Naim NAIT
Having already made their name producing solid-state pre-/power- amplifier separates, Naim launched a low-powered integrated amplifier that embodies the qualities of its amplifiers, aimed at cost-conscious audiophiles.[8][9]
Since the Nait was launched in 1983, it has been re-imagined six times. In 2013, the NAIT brand is a three-amplifier range,[10] consisting of the entry-level Nait 5si, the top of the range Supernait 2, and the mid-range Nait XS 2.[11]
History
Up to that point a manufacturer of solid-state pre-/power- amplifier separates, Naim Audio wanted an entry-level integrated amplifier to complement their range and widen their appeal, so they worked to create a low-powered model that shared the "family" characteristics and sound. The approach, seemingly against the received wisdom of the time that power and sound quality go hand in hand, remained nevertheless controversial, despite the fact that NAD Electronics had trail-blazed five years earlier with the top-selling low-cost audiophile amplifier, the NAD 3020.[8][12] The Naim Audio Integrated amplifier (or "NAIT") was launched ten years after the firm was founded.[8][4] Sam Tellig of Stereophile said that the Nait was "a profoundly anarchistic, almost subversive product".[2]
In terms of styling, the Nait, priced in the UK at £253, was housed in a small black aluminium "chrome bumper" case[1] shared by other "half-size" Naim components at the time.[Note 1][8][1] The first "chrome bumper" version was followed by a second, then two "Olive" incarnations (including the Nait 3), and three Nait 5 versions. All bear the Naim Audio logo, but none have any markings or other indication of their model numbers on the fascia.
Between 1983 and 2007, Naim had only one integrated amplifier on offer, although the product has seen several guises. Naim extended the range with the Supernait in 2007, and the XS barely a year later.[13] In 2013, the NAIT range consists of the entry-level Nait 5si and the top-of-the-range Supernait 2, with the XS 2 slotting in the middle.[11] Some of the models provided an upgrade path for their equipment by allowing the simple insertion of an external power supply unit.
Design and power
Naim insist on the unimportance of specifications in general, and never published technical specifications for this low-powered design.[8][14][15] Trade speculation of its power output ranged from 5 to 15 watts per channel.[8] Naim confirmed years later that the Nait is rated at 13 watts.[1][Note 2] Part of its mystique seemed to stem from its low power: in developing the successor to the Nait, Naim founder Julian Vereker remarked that R&D "cooked up a more powerful version and presented it to me on my return [from holiday but] it sounded awful."[2]
In its product manual, the NAIT is said to have "low continuous power output ... balanced by a very large peak current capacity so there are no restrictions on the size or type of loudspeaker that may be used. But please don't expect the impossible".[16] Hi-Fi Journal wrote that "the NAIT excelled in musical terms ... and would comfortably drive loudspeakers that caused other amplifiers to sound lumpen and distinctly unmusical".[14] And for that reason, many people who owned the Quad Electrostatic Loudspeaker (ESL) – which are known to be a very difficult load for amplifiers[17] – would choose the NAIT to drive their speakers.[8] Reviewers attribute the perception of power of the NAITs to the over-engineered, dedicated power supplies that ensure generous current delivery for musical transients.[18]
The Nait 5 is a redesign from the ground up.[1] Subtle mechanical and electronic changes introduced in the Nait 5i (italic 'i'): control of internal heat dissipation, wiring, radio-frequency interference and mechanical vibration through more efficient materials, compliant mounting and decoupling.[19][5] The Supernait benefits from a fully active line-level preamp developed for the NAC 552 pre-amplifier, and its output section is derived largely from the NAP 200 power amplifier.[20]
In launching the 2013 NAIT range, Steve Sells, electronic design manager of Naim, explained how the new NAITs fulfilled the goal of delivering sound quality performance. They are stripped of superfluous components and features, and as such, the digital–analogue converter (DAC) previously available on the Supernait has not found its way into its successor.[5] The transformer is deliberately positioned as far away as possible from the inputs to avoid electromagnetic interference, while the power supply and its capacitors are closer to both the transformer and the output devices.[5][20] Non-audio circuitry for controlling the amplifiers are optically isolated from signal sections, and are designed to power down when not in use, to avoid interference.[5]
Construction
While reviewers criticised the styling of early NAITs of having a distinctly "cottagey" feel,[21][22] Ian White observed that the typical Naim product is "meticulously laid out, clean, and well put together".[23] Housed in the same small, black "half-size" aluminium cases used by Naim pre-amplifiers and power supplies,[8] the electronic components are of high quality and "discrete" – that is, with few or no integrated circuits,[8][2][15] mounted on a single, printed circuit board. For many years, Holden & Fisher supplied custom-made toroidal transformers used in the amplifiers. The ones used in Nait were rated 100 VA,[8] but these have been progressively up-rated over the years, with consequent increases in power output: the entry-level Nait 5si has a powerful 300 VA transformer for the delivery of 60 W of rated output.[24]
While Naim's practice of using DIN connectors has been regarded by some reviewers as "quirky" or "arrogant",[21][25] DIN sockets continue to be Naim's choice for line-level inputs. From standard DIN sockets used in the "half-size" NAITs, Naim upgraded to higher-quality locking DIN sockets on the Nait 3. However, models since the Nait 5i include a number of hard-wired parallel inputs using RCA sockets.[4][26] But as the Nait was conceived as an entry-level offering, the RCA connector – undoubtedly more popular with mass-market equipment – was offered in place of the BNC for the phono source.[8] In all 2013 models, RCA inputs double the DIN counterparts.[5][26] Banana plugs,[27] the absence of tone controls,[28] the tendency to harshness when cold[14][20][26][27][29] are family traits inherited by the Nait.
"Nait 1" to Nait 3 have hard-wired mains cables. Since Nait 3, the on–off switch has been located on the back of the amplifier – given that units are meant to be permanently switched on; since Nait 5, power is delivered through a detachable mains cable via an IEC connector fixed to the back panel.[26] Consequently the front panel looks more minimalistic.[1]
The 2013 range of Naim equipment has aluminium chassis and sleeves; the fascia is die-cast zinc.[5] Inside, circuit boards "float", and the rear-mounted mains switch and IEC socket are decoupled to reduce microphony.[3] Techradar noted that the Nait XS, launched in late 2008, is the first Naim device to use a new bayonet PCB-mounting technique to "float" the circuitry.[3]
Popularity
Strong and polarised opinions about Naim amplifiers led to the Nait being called "one of the most controversial and famous integrated amps in the history of HiFi" by Lucio Cadeddu.[7][8] This controversy has been as much to do with the company's refusal to follow the fashion of "audiophile-approved values" – such as power ratings and holographic soundstage – as its idiosyncratic preference for connectors other than RCA connectors and its eschewing of tone controls.[21][22][26] The volume control always sits on the "wrong" (left) side of the facia.[25] However, the trade noted that the unique sound of the Nait caused it to become "an instant classic" upon release.[1][26][30] As one of the most recognisable pieces of hi-fi, the Nait has acquired an "iconic" and "legendary" status among integrated amplifiers;[7][8][1] Hi-fi World said: "If there was ever a quintessentially British affordable audiophile amplifier, the Naim Nait is it."[1]

Nait (1983)
The Nait, created by Julian Vereker, is a minimalist black shoe-box design that includes a phono and two line-level inputs – one for tuner and one for tape recorder.[1] The phono input, for moving magnet cartridges, is derived from the NAC 32 pre-amplifier.[8] On the left side of the front panel, a plastic volume knob is adjacent to a small-diameter rotating potentiometer that controls the balance. Then follows a bank of three press-button selector switches – for each of phono, tuner, tape – then a power on–off button. On the right side is an light-emitting diode (LED) indicating activity status.[8]
There are two major variants of the Nait, and apparently several minor variants with different motherboards. The simplest and most notable distinction between older and later models is the LED on the fascia: the red LED on the earlier Nait became a green one on the later model.[8] The balance control unusually only attenuated the left channel by up to −3dB;[8][1] the lack of obvious markings to indicate a central position was criticised for being "slightly confusing".[8][14]
Tellig was ambivalent about the "Nait 1" in Stereophile: noting that it was "a good-sounding little amp", he criticised it for "look[ing] very cheaply made, inside and out", and for its lack of features, particularly the absence of an 'aux' or 'CD' input, tone controls, or moving coil input.[28]
Nait 2 (1988)
As in its predecessor, the Nait 2 uses gold-plated RCA jacks for phono, and DIN jacks for line inputs.[15] The pre-amp can be factory-modified to work as a preamp-only unit – the upgrade path assured by partnering with Naim's own stereo power amplifiers – in particular, the NAP 90 and NAP 140, that have in-built power supplies for their own pre-amplifiers.[15]
Although he was unimpressed with the poor value for money of the "Nait 1",[28] Sam Tellig said the Nait 2 was peerless at the US imported price.[Note 3] He attributed his positive listening experience to the attention to small detail in design, manufacture and testing at Naim.[2] His Stereophile colleague Robert Harley disliked the Nait 2 for its "unusual styling, DIN connectors, relatively high price, and poor performance on the bench", but applauded its sonic qualities.[15]Nait 3 (1993)
Both the external styling and the electronics of the 30-watt Nait 3 are derived from the NAC 92 preamplifier and the NAP 90/3 power amplifier with which it was launched – it is basically the NAC 92 and NAP 90/3 in one box.[31] Its flat slimline Olive case with rounded edges measures 17 by 12 by 2.2 inches (432 × 305 × 56 mm).[1] The Nait 3, costing £500 at its launch, has five line inputs labelled aux, CD, tuner, tape, and VCR, the first one of which (aux) is an optional phono input if fitted with suitable phono boards.[32]
Nait 5 (2000)
Naim skipped '4' and launched the 30-watt Nait 5 as successor to the '3'.[9][22][23] It is powered by a 180 VA transformer and is a full redesign employing surface-mount technology.[1] In terms of styling, it is housed in the same low-vibration black die-cast alloy casing employed in the '5 Series', and measures 17.2 by 12 by 2.3 inches (43.7 × 30.5 × 5.8 cm).[22][23] Like its brethren, it has the same low-energy-transfer feet and decoupling pillars inside the case that help better isolate the circuit boards from vibration.[23] The Nait 5 has six inputs, all DIN sockets: CD, Tuner, Tape, A/V, Aux 1, and Aux 2, three of which have record output facilities. There is no phono input, but the Aux 2 input can accept an external phono pre-amplifier. There is no balance knob on the fascia; A button on the fascia mutes the output from the speakers.[23]
In terms of construction, its power supply includes a new 180 VA toroidal transformer,[1] with separate secondary windings for the pre-amplifier and power-amplifier circuits; all the pre-amplifier's supply rails have double regulation.[23] The amplifier's volume control section uses a discrete resistor ladder and microprocessor-controlled switches. The Nait 5 possesses a remote control function, previously unavailable to the NAIT, that controls the volume and the balance. The "5" can also be converted into a pre-amplifier or power-amplifier by adding an external power supply.[23]
NAIT range (2003–13)
The NAIT is henceforth a range extended across its three series – the entry-level 'i Series', XS, and Classic series.[Note 4]
The Nait 5i (italic 'i') benefits from a number of important but subtle improvements over the "5i". Visually identical to its predecessor except for the 3.5mm jack for portable devices on the front panel, reviewers noted sonic improvements "from the first track"; it is demonstrably better at handling higher sound pressure levels than the '5i'.[19] Improvements can be attributed to mechanical and electronic changes. More efficient ceramic heat sink material is employed and PCB wiring has been restructured; mains input, audio connections and circuit boards are compliantly mounted to control resonance and vibration. The level of electronic feedback employed has been reduced so that transient intermodulation distortion is lowered, more stability is achieved for difficult loads – and RF filtering in the pre-amplifier section is improved.[19]
Nait XS:[Note 5] Reviewers have described the XS as a "Supernait in the slimmer casework of the Series S".[10][4] Launched in late 2008, the XS is rated at 60 watts, with six inputs, a remote control and a facility for unity gain. The power to the unit is supplied by a 380VA toroidal transformer.[3] The amplifier has four inputs where the user may choose between RCA phonos or the DIN sockets that are wired in parallel.[4][34] In addition, there is a 3.5mm stereo input with auto-switching on the front-panel, suitable for an MP3 player. A powered input, provided for turntable users, is designed to supply one of Naim's external phono pre-amplifiers.[10][4][3] The unity gain option and AV bypass function allow it to be used in conjunction with an AV processor in a home cinema system.[3] It also includes optional RS-232 interface for custom installations.[4][3] The XS omits the internal DAC.[34]
The amplifier sections can be isolated electrically into 'pre-amp' and 'power-amp' sections. The XS is programmable so that pressing "play" for a CD command on remote control will cause the amp to select the appropriate input.[4][3] The transformer has separate secondary windings for each of the pre-amplifier, the display illumination, the relay switching and the two power amplifier channels. The amplifier wiring can be user-modified (by using a shorting plug) so that the pre-amplifier section of the unit can be driven by an external Naim power supply[10][4][3] while the on-board power supply feeds the power-amplifier section.[34]
Supernait: Released in 2007, this amplifier incorporates connectivity for digital sources that facilitate direct connection of computers, media servers and the like. The Supernait's circuitry is supposedly identical to that of the XS,[34] although it has more features, a power supply with a "'proper', meat-eating, bourbon-drinking, toroidal transformer with seven discrete windings" – and can deliver 80 watts.[18] The amplifier has a balance control, headphone socket,[34][35] six analogue line inputs.
The five digital inputs include two coaxial and three optical, including a combination mini-jack/mini-Toslink connector with auto-switching on the front panel.[18][34] The amplifier's 24-bit DAC can be called from any of five S/PDIF inputs. The digital input section runs a Crystal CS8416 receiver chip, which can identify incoming data as 44.1, 48, 88.2, 96, or 192 kHz. To eliminate digital gunge, the digital board powers down when an non-digital input is active.[20] Like the XS, the Supernait is configured to accept external power supplies. It also caters for the possibility of bi-amping suitable speakers by adding a secondary power amplifier.[18][35]
NAIT range (2013)
To mark the 40th anniversary of Naim Audio and the 30th birthday of the original NAIT, Naim unveiled a new 3-product range under the "NAIT" brand: the Nait 5si, Nait XS 2 and Supernait 2. The three units all share a styling, but the height of the case increases for the higher models. The range has seen a general uprating of the transformer compared with the versions they replaced, allowing for better power delivery. The manufacturer claims use of better components in critical areas and new circuitry. All three models have built-in headphone amplifiers. The digital–analogue converter has been removed as being available either as a separate unit, or as part of the Uniti.[5][6]
Nait 5si: The entry-level NAIT and the direct replacement of the NAIT 5i (with italic 'i'). Through using a more powerful transformer, the rated power output has increased to 60W per channel.[5][6]
Nait XS 2: Positioned as the mid-range offering. Its power output increased to 70W, from 60W of the NAIT XS. The amplifier incorporates a headphone output via a class-A headphone amplifier. According to the manufacturer, the NAIT XS 2 also benefits from technology originally developed for the NAC 552 pre-amplifier that reduces noise floor levels.[5][6]
Supernait 2: The second generation Supernait the becomes the flagship integrated amplifier in the Naim stable. All digital inputs and audio circuitry have been removed, as has the independent record output selection. According to the manufacturer, all inputs are individually decoupled, like in all pre-amplifiers since NAC 282. The Supernait 2 incorporates a headphone output via a class-A headphone amplifier.[5][6][Note 6]
Subjective comments
In Stereophile, Sam Tellig, who was unimpressed with the poor value for money of the Nait,[28] said the Nait 2 "sounds insanely great" and that there was "[no] better-sounding integrated amp at the price".[Note 7] He remarked that and the 2 resembled his Krell KSP-7B / KSA-80 combination sonically, but lacked "ooomph, kick, balls in the bass".[2] Although his colleague Robert Harley disliked the Nait 2 for its styling, connectors, price, and poor performance on paper, he found it to be the most musically satisfying of several amplifiers in his test.[15]
Reviewers of NAIT rarely fail to mention their characteristic PRAT (pace, rhythm, and timing) sound of Naim.[8][9][21][22][23][25][27][30] Channa Vithana, wrote comparing the Nait, Nait 2, Nait 3 and Nait 5 in the October 2007 edition of Hi-fi World:...the original Nait had the best musical timing with precision tempos. The Nait 2 had the most tuneful bass with a much quieter musical background in comparison to the Nait. The Nait 3 had clearer sound overall than all the others, and opened out the music superbly by being the most free flowing. The Nait 5i was easily the most refined, yet was more immediate too. It proved superb with the tonal qualities of instruments, and added a dash of sweetness to higher frequencies also.[1]David Price, writing in Hi-fi News, said that with the earlier NAITs gave the impression of "something overly reminiscent of British hi-fi's 'cottage industry' past", but remarked that the Nait 5 made "all other integrateds sound positively pedestrian".[22] Ian White said the Nait 5 "sounds like a Nait 3 that finally finished going through puberty and emerged as a mature adult",[23] and What Hi-fi? referred to the Nait 5 as "one of the finest amplifiers available this side of 1000 pounds";[36] In The Absolute Sound, Wayne Garcia noted that the "staggeringly good sound and wonderful value" of the Nait 5i contributed significantly to raising Naim's profile in the US audio market.[37] Matthew Masters remarked about the 5i amp and CD player that "it didn’t seem to matter how complex or demanding the music was, the Naims would sort out the elements then present them in a perfectly-timed and coherent musical picture that helped me understand – and feel – precisely what the performers were on about".[27] Commenting on the Nait XS, Malcolm Stewart wrote that the NAITs were "a musically communicative, minimalist design".[3] Confirming Naim's upgrade philosophy – the belief and objective that incremental improvements to their equipment can be gained with improving the quality of the power source,[31] Martin Colloms of Hi-fi Critic concluded about adding an external power supply to the top-of-the-range Supernait:
... simply transformed the sound quality, immediately bringing a substantial and obvious improvement. Supernait-with-Hi-Cap has greater poise and dynamic range, is better at getting feet tapping, has less 'character', a bigger soundstage, and the bass is tauter with less 'thump'.[38]
