Re: Looking for a system upgrade (if possible)

I'd be looking to change the speakers first - for best sound quality. Away from low efficiency slimline ported / transmission line speakers. To medium efficiency sealed box speakers with 12" or bigger woofers. Or to high efficiency designs. This would be at the expense of losing the fashionabl...

Looking for a system upgrade (if possible)

I'm considering upgrading my current system (well possibly just the amp to be honest) - and I appreciate that NVA can build real Hi-Fi in the UK ... I am easy in terms of the sound signature I am looking for and in summary I am looking for "beguiling" for want of a better word. I mostly li...

Re: Which pot for NVA passive? 10K, 50K, 100K ??

OK would a 50k pot be easier and more universal so I can use the AN DAC and other DACs with it too?

Yes it's in their documentation and general AN DAC users know this too. I guess that's because their DACs are meant to go with their valve preamps. So yes, 100k pots (50k ish should be OK but certainly not 10k).

Re: Which pot for NVA passive? 10K, 50K, 100K ??

I now own an Audio Note 0.1x DAC which to my ears sounds very good (bought it used - can't justify the cost new) - but AN advise the preamp should ideally be 100k - but 50k will suffice (my P50a is 10k I believe). Is there anyway I can get a 50k or 100k pot fitted to my P50a preamp as a result of th...

Well - when I've saved up a little more I will probably get my current NVA P50sa upgraded to a higher end pot and silver wiring etc.

Re: Which pot for NVA passive? 10K, 50K, 100K ??

Actually Glen just replied 'Pre-amp pot value doesn’t matter with matching to the power amp.'

I wonder why that is when many others are saying that 100k is the right fit?

Obviously Glenn knows best - but to say it doesn't matter surprises me nonetheless.

Re: Which pot for NVA passive? 10K, 50K, 100K ??

Because I swap between solid state power and valve power - is it possible to make an NVA preamp with selectable 10k and 100k ?

If not - I use the Croft power the most so - an upgrade from my 10k to a 100k might be in order.

Re: Which pot for NVA passive? 10K, 50K, 100K ??

Ok reading between the maths the conclusion seems to be: ..as long as its maximum resistance does not exceed the input resistance on the target (input of power amp) it makes absolutely ferk all difference. Well the output voltage of most digital sources are 2V - and the input impedance of a Croft Po...

I'm not sure yet - but generally is there a mathematical rule I can work with?
