Nap 180 with Threshold SL 10 pre


Maybe this is a stupid cuestion but I’ve just bought a Naim Nap 180 power amp and I’m not completely sure about how to use it. I want to connect it to a Threshold SL 10 preamp. I’ll do it using a Chord 2 Rca to 4 pin din cable.

Speakers are Tannoy’s Berkeley connected with Naim Nac 5 speaker cable.

Anything to have in mind?. I don’t understand anything about electronics so I’m a bit frightened of blowing up the hole system.

I’m really excited about having my first Naim device, but everything I read about this brand is that their devices are “tricky and delicate”.

Any advice will be appreciated.

Thanks to all and kind regards.

Welcome Pillo917.

A Chord 2 x RCA Phono to DIN4 cable should be fine for the physical connection.

As for Naim being “tricky and delicate” it’s not that so much that - Naim amps are extremely well built and generally very robust - as that Naim amps are designed in a particular way and usually best match Naim pre-amps as they like a bandwidth limited signal (gently rolling off around 40kHz) to work from. Ultra wide bandwidth pre-amps can potentially upset a Naim amp. The amps also don’t have extra inductance networks on their output (this sounds much better) instead using a rather elegant solution of relying on the speaker cable for the necessary inductance for overall stability. This does mean you need to be careful with the speaker cable that you use - it needs to be low in capacitance and moderately high in inductance and of least 3.5m per channel in length (longer here usually sounds better, up to 10m+). I see you have NACA5 which is perfect, so long as it’s more than 3.5m per channel in length and well terminated.

You can read more about this in the FAQ;

The Threshold is a rare bird here in the UK. I do recall the Stasis power amps being well regarded back in the day though and I did hear one such system with a Stasis amp sounding very good into Magneplanar IIIs when I was in Boston during the '80s. Is it an ultra wide bandwidth design? You may not know for sure, but I guess it’s easy to find out how well the Threshold and Naim amp pair up by giving them a listen.

By the way, it’s a fairly old bit of kit I would guess? Do you know when it was last serviced? That will likely make a substantial difference to performance.

Hell Richard and thank you very much for your kind answer.

I knew a very important aspect on using these device was to use original Naim cables. That’s been the first thing I’ve read everywhere. I’ve bought a 3’75 mtrs. pair on Nac 5.

Connecting cables are on the way to home. As soon as I have everything ready I’ll let you know how it sounds. I have great expectations.

About the Threshold, it’s a rare bird everywhere. Serviced in 2017 and sounding … well, great to me.
