Naim Nac-N272 vs Cambridge 851E, N, D with ATC SCM50ASLT
Posted by: Tesilk on 17 January 2017
Hi everyone,
I am thinking about moving to Naim from Cambridge Audio. Current setup - Cambridge 851E, N, D connected via balanced xlr to ATC SCM50ASLT.
Will it b much better if I replace all the Cambridge gear with 272? And then if I add an XPS or even better in the future?
Thanks,
Serge
Ah thanks, I see - they cheated by modifying a pre-made cable. I'll be doing it from scratch.
I'll actually use two separate lengths of Mogami W2549 wired as Pseudo-balanced, Prehkeytec DINs and Neutrik XLRs (I'll use W2549 as it has lower capacitance than W2534).

It would be nice if you can share it with me when it will be done - maybe will be my next step. You can pm me whenever you want.
The idea so far was at least to get those DINs working.
After a lot of reading I decided to start with 2534, but will certainly try 2549 later.
I can say that 2534 sounds amazing.
When I made a stereo interconnect (ND5 XS to Nait XS 2) I made up 2 cables to try against each other... 1 W2534 stereo pseudo-balanced construction and 1 using W2534 stereo twinax construction. In this application the W2534 stereo pseudo-balanced won out by a very small margin, but the biggest difference wasn't the type of the cable it was the pseudo-balanced vs the twinax construction.

I see, could you explain please, how the pseudo-balanced construction is made? I did not hear about it before.
With Coax (and twinax) the return current flows in the screen
With pseudo-balanced, two cores are used to handle the 'signal' and 'return' currents, the screen is connected to the return (0V) core at the source end only.
A very rare variant also exists in cases where the shell of the connector is earthed separately from the 0V pin: the shield can be connected only to the shell, and not to the 0V pin. However, for this to work well and without risk, it's essential to know how the amplifiers are earthed internally, so this construction isn't generally used (and I didn't even try it as I don't know that Naim amps are fully stable when connected this way). This construction is normally only used with amps specifically designed to be connected like this.

Well, after checking with technicians, they confirmed that actually the pseudo-balanced construction was implemented in my set also. )
