NVA Pre Amplifier

[Principia]

Looking for a new preamp, the P50 SA and the P90 are both £300, whats the difference between the 2 in terms of sound quality. Anyone experience of using either passive with Quad QMP Monoblocks?

Thanks

The 50SA has a superior potentiometer, a Stepped Attenuator. The 90 doesn't. Sorry doc

He is right, the P50sa will be better sound wise, the P90 is when more inputs and a balance is needed. You can then step the P90 up to a P90sa which is better again than the P50sa.

I know that passives work with quad power amps. Would be interested myself in the SQ difference. For me both a stepped attenuator and two vol knobs have their inconveniences so its a best compromise based on sound and connectivity.

I have the P90SA; having two volume controls is no burden at all. I change both without really being concious of it. I

Thanks for the info the 50 SA looks favourite since I only have CD input the increased flexibility of the 90 is not needed
