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.

Thanks Clio09. I would go step-by-step. So right now I am looking at my existing NAD C352 to run as preamp for the TVC. At some point in future I will add the RWA power amp.

Not sure you're going to get the best out of the Promitheus with the NAD. One option to consider is the Lightspeed attenuator. This is a passive preamp using photo-optic technology. No transformers and no resistors. I just bought one and it is everything it is advertised to be.

Go to DIY.com and do a search for Lightspeed. There is a very long thread on the preamp. Nelson Pass even participates and IIRC uses the technology. The preamp is available for about $350. Single input and single output only. This will work with your NAD as it is pretty immune to impedance matching. Also, the new Pass B1 buffer is another option at $895. Again will work with the NAD.

Just now ordered the Promitheus Reference C-Core dual box with Elma switches. Have never heard one, but ordered it based on positive feedback/reviews from fellow audiogoners/asylum inmates/audiocircle pals. The estimated wait period in 3 weeks.
This is going to be my first "separates" component. Will eventually move to a separate power amp when budgets permit. So the "upgrade bug" finally got me!!

Let us know how it sounds after you've let it settle in a bit.

The TVC was supposed to be delivered today. But man...I missed the DHL delivery guy today. Will have to wait till Monday for their second attempt. DHL does not have the option wherein, I can take the delivery attempt ticket and collect the package myself. Oh this is killing me!!!!!!!!!
