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.

I also bought a pair of Ref C-Core TVC unheard a few months ago and i'm using it in a system that is not ideal for passive pre setup due to lowish input impedance of my Bel Canto Ref 1000 monoblocks and inefficient Dyanudio Confidence C1 speakers. But it works and works well to my ears especially with >100 hours use. Natural sounding with good resolution.
It would be interesting to hear of your impresison later.
