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.

Dave,
Thanks for your response. How does the Bent Audio TVC compare to the Promitheus? I have heard good things about Pomitheus. That was the reason I thought I could replace the NAD's built in pre-amp section with it and then eventually use it with RWA's power amp. I also hear from online forums that RWA power amp is better than the integrated. This was another reason I decided with the Promitheus. I appreciate your response and will look forward to some more before I decide.

Regards
Dave,
I get your point. But I will have to wait for at least a year to get the RWA, since budgets are routed elsewhere currently.

Mrjstark,
Yes, I m looking at the used market too. Can you please throw some light on the "more gain" part. When it comes to "tech" terminology in the audio world...I m a noob. My concern is I will be going down from 80W/ch to 30W/ch. So will the sound (music) detiorate if I use the RWA 30.2 with the Quad 21L I own? I am really very happy with my Quads and have no intentions to change the speakers. If the RWAs cannot handle the Quads, then I will look at some other amp/preamp combination.

Ngjockey,
My source is the Marantz SA8260 that I am pretty happy with and do not intend to change it in the near future (unless it gives up). Occasionally I will also use an Oppo 970 player.

Thank you guys for your responses.
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,
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
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.
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!!
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!!!!!!!!!
Ngjockey,
The source in the case of Promitheus TVC does not seem critical. I get my moderate listening volume even if I use an iPod and the volume knobs set at position 10 of the available 24 positions. I believe it is the power amps's input sensitivity that matters in this case.

Mariusz,
I did not need any gain and the TVC worked fine as a preamp for my NAD's power amp section.

Clio09,
You were right. The input sensitivity of the NAD was fine for the TVC.

I am extremely happy that I decided to go with the Promitheus TVC. It has matched very well in my system. The initial hours were not enlightning. But after 40 hours I was surprised with the performance of my NAD!! Yeah, I know that the TVCs do their magic, but I did not think that the NAD was capable of handling that magic. Of course the full potential of the TVC cannot be handled by the NAD. I require a separate power amp for that.

I plan to start a thead later in May after I have done some critical listining with the Promitheus. This will not be a review - but a pointer to all integrated amp owners who have the capability to use a external preamp/TVC. I was so fraustrated searching the web for such a combination. The closest I came to was at a mention of how a person used his TVC set to MAX and then control the integrated amp to control the volume. That was certainly a waste of TVC - I thought.

Anyways, I keep getting surprised by the TVC - the more I listen to it and find certain nuances in my system that I never heard before. More later.
Jaspert,
I have added a review of the Promitheus Reference C-Core in the reviews section.
