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 Mingles,
The Bent also costs much more than the Promitheus. I heard about the buzz in AudioCircles forum, but there were ways to rectify it - and simple ones at that. Right now I cannot spend more than certain $$s on the preamp.
But you got me thinking by making the same point what Dave has mentioned above :-)
Thanks

Anyone with Promitheus+RWA Sig 30.2 combination or NAD+Promitheus combination? Your inputs will be highly appreciated.

Thanks,

Go with integrated first.
If you need more gain (volume) buy "Goldenjack" attenuators ($50 direct). If you need more inputs get TVC.....it is great for the money(read on).
I see that you posted this question all over the place.....that is all good but the wise thing to do would be to start small. Meaning - RWA integrated. If needed.......
Add attenuators later. That should easely drive your speakers.
If you are thinking about passive TVC, I would dump the idea of the RWA integrated and go with RWA amp. There is a difference in sensetivity between the two. RWA Sig.30.2 amp is 100K which is more suitable to work with seperate preamp.
Just my 2c.

Hi Mariusz,
Thank you for your reply. Honestly, I do not know if I require attenuators or not. I don't even know what that would do. I will surely look up some sites and try to understand that. Yes, I was looking more at the power-amp rather than the integrated, and hence the TVC. Also, the TVS would give me more inputs compared to just 1 on the RWA amps.
The reason for posting all over the place is to get the most from other's experience. I feel that the forums are a best place to get these. And you also get to know about stuff that you were not aware of.
I really appreciate your advise - especially getting my attention to the sensitivity of the RWA power amp.

Reviving my old thread. Need to get a second opinion. My integrated amp's power amp section specs are as follows:

770 mV / 20k ohms / 470 pF

I am not techie and got this from NAD directly. Are these specs suitable for a Promitheus TVC?

Thanks
