Promitheus Ref TVC and RWA Sig 30.2 Power Amp

The source(s) is/are more critical to a TVC, or any passive, than the amp.

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.

I have a 1st gen Bent TVC with S&B transformers. It's an excellent performer with stellar imaging and transparency. I had a Promitheus about a year ago. Everything about the Bent is better. The Promitheus had a buzz I could never get rid of. The Bent has a better ground design. There's a switch for each channel allowing you to float or ground the output jacks. The Bent also switches positive and negative inputs when the source is changed. This prevents crosstalk and eliminates any ground issues. The Promitheus and Sonic Euphoria have a common ground for inputs which can lead to problems.

Bent just released a new passive using autoformers. I heard it about a month ago and was impressed. In my opinion, autoformers have more bloom than TVCs. TVC's often sound thin in the midbass region. If you do the comparison, you'll know what I mean.

In my experience, the Sonic Euphoria was better sounding than the Promitheus. It had significantly better bass. It also uses autoformers.

FWIW, I think the money you put into a passive would be better spent on your goal of getting an RWA integrated.

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,
