Promitheus Ref TVC and RWA Sig 30.2 Power Amp

Hi All,
The itch to upgrade is getting stronger day-by-day and I think I should start by asking this wonderful community, certain questions that I have no idea about.
I do not plan to upgrade everything at once - as budgets do not permit. I currently have the NAD C352 integrated and want to start with the Promitheus Reference TVC preamp. I will use my NAD as a power amp for now. When budgets permit, I plan to get the Red Wine Audio Sig 30.2 Power Amp. This is based purely on the reviews from many people online and also 6moons and other online sites. I am not sure if this amp will be good enough to drive my Quad 21L.

The questions are:
Will the Promitheus and RWA work fine with my Quad 21L speakers?
What should be my expectations after I replace the current preamp section in the NAD with Promitheus Ref TVC? Will the sound step-up be huge or slight?
Is this the right approach, or should I just upgrade to a better integrated amp (like Primare, Creek, Musical Fidelity, etc)?

Thanks much.

Hi

I have the Bent Audio TVC (which would offer similar performance to the Promitheus) and I also have the Red Wine Audio 30.2 integrated version.

I have run the TVC with the Red Wine amp (with the built-in Gold Point attenuator in and out of the circuit) - in both cases I preferred the 30.2 alone with it's own attenuator. It is very well matched and perfectly voiced to run with the Gold Point (gives you a remote volume control as well). It is voiced on the warm and full side but does not sacrifice any of the detail.

If you only have the need for a single input, I would suggest passing up the Promitheus and just save-up for the Red Wine 30.2 integrated. I'm sure it would sound great with the Quads.

I've never heard the Prom but I'm sure that the Bent is comparable if not even better (as far as features go). The Red Wine integrated and the power amp are virtually the same except for the Goldpoint attenuator (also input Z - 20K for the integrated versus 100k for the power amp).
The sound of the power amp version will be greatly influenced by the sonic signature of the preamp preceding it. The TVC's are very transparent and neutral, however the Sig 30.2 integrated is just nicely flavoured as it is.

In my case, the only reason I would consider going with the power amp version is to precede it with Vinnie's Isabella preamp.

Once again I say just go with the integrated version.
