Naim Nait 2

A question regarding speaker cable connections for my  Nait2 . I seem to remember Richard Dane posting recently about only using Naim connectors at the Nait end ?? The original speaker cables had these plugs but are long gone . I haven't used the Nait 2 for quite some time but have recently had it serviced by Darran and it will be the centre of a 2nd system . The reason I'm asking this now is because I've just changed my speaker cables in my main system and thought I could keep my old TQ Black speaker cables for the Nait2 , are the TQ Banana plugs really unsuitable ?

Pete, yes.  Quite apart from providing a similar metal to metal contact, the Naim speaker plugs also reduce any torsional stress on the amp speaker sockets which are soldered onto the PCB and can develop a bad joint or even separate from the board if other plugs are used.

I can't help thinking the stress issue is a bit of a Catch 22, as the stiffness of NACA5 is surely part of the cause.

Hi, blown away by this little amplifier...

Has a bounce, an energy which is hugely infectious. Really makes me want to stay listening waaay beyond my bedtime 

Can forum advise closest sound to this in a more powerful amp with remote control facility for volume? This thing is amazing! Has a love of life/music I've not heard before 

Just wish it went louder., or is that the Naim upgrade spiral I've heard of.. ?

I bought mine spanking new when it had just come out in 1990. If I could alter history, I'd still own it- ad infinitum.

Paired with the (even newer, hot off the press) Rega ELAs, it was-and remains- my ultimate amp/speaker team. 

Amen.

I did wonder that Chris. As Richard mentions, the spacer bar on the Naim plug housing helps spread the mechanical load across the two pins and as much as i find the unwieldy A5 a PITA, its stiffness means you can pre shape it before connecting to minimise the stress on the sockets. 

Just to add, i've been enjoying the Nait 1 of late and It's proving to be a fun little amp within its limitations. I'm not sure how well it will fit in the modern digital world as most kit is shoving out around 2v and that really reduces the volume control range. I've configured the output of my DAC to be 1V which is more in keeping and gives more travel. Fronting it with a Naim source would mean using attenuated leads

Longer term this may be an itch that has been scratched but it'll have been fun scratching

Chris, yes, the speaker connectors are a must with NACA5.  I can't imagine anyone using anything else with their NAIT, surely..?

(well, some maybe still using NACA4...)

I'm certainly not disputing the effectiveness of using NACA5 and Naim plugs, I'm just wondering if the plugs were designed as a solution to the 'problem' of the stiff cable. Given the popularity of TQ Black, I would be tempted, in Pete's position, to at least try it, he could probably borrow some A5 from a dealer to make the comparison. 

The Naim speaker connectors were designed to best allow the pins to make the most natural contact down the socket shaft - i.e. minimise any torsional that might force the pin to make a poor or less optimal contact.  The housing may also act as a kind of isolator for any vibrations picked up by the speaker cables.  Bottom line is that it sounds better with the plastic housings on than off - just be sure that the pins can move slightly otherwise it may mean that excess solder is jamming them up within the housing. Oh, and yes, it also helped out with the PCB mounted sockets on the NAITs and the NAP90.
