In search of more power ... MF? V Alstine?

I like the sound of my Opera Consonance a120 Hybrid Integrated amp (90 w), but my 87 dB speakers and large room size dictate a need for more power. Somewhere around 200-250 wpc perhaps. I was considering staying with an integrated so I could help fund my new purchase with money from selling my current one. I auditioned the Krell KAV 400xi - it was powerful and dynamic with kick-ass base like I've not heard before (too much?). BUT, not lush enough in the mid-range for me. So next up is a Musical Fidelity A5. I will audition this in a couple of days. BUT, Van Alstine Fet Valve Ultra 550 keeps creeping into my pea-sized brain. I've never heard any of his stuff, but I can't shake this nagging suspicion that it may be just what I'm looking for. However, I live in Atlanta, not in the frozen tundra a.k.a. Minnesota, so an audition seems impossible. How does the quality (sound/build) and mid-range compare between the Musical Fidelity and Van Alstine Fet Valve? And what about using my a120 pre-outs to provide the source for the 550? Or can I buy a better pre-amp than the a120 for $600 (the amount I'd likely get if I sold the a120)?

Jaybo - Thanks. BAT, CJ, etc. ... if V.A.'s build quality is on par with those then I'd certainly be happy with that.

TonyPTony - Thank you for explaining the sound qualities of the 550. You described it very well.

After hearing from both of you I feel comfortable about ordering one to try out. I don't have much spare time to try numerous gear and depend on research to help me narrow the field considerably. Also, I don't have extra cash to be making mistakes. So your replies are a great help to me. Thank you again.

AVA build quality has always been ABSOLUTELY first rate. He has been in business...well I don't know...30 years? The basic principles have always been, No designer components (magic caps or whatever) or anything of that nature...just top quality components, top quality engineering and top quality build. Very straight forward.

Danny, good luck if you get one in your house to try! I'll certainly be hoping to hear from you and how it sounds in your system. I have to admit I'm a little nervous; my gear is mostly out of the "main" mainstream. Not too often that something I own winds up getting looked at by someone else!

As always, there's never a guarantee, and YMMV, but I was a SS guy for a long time and had a chance to hear plenty of good tube gear in my system (CJ, Moscode, VTL, AR, Quicksilver and others) and other SS gear over the years. Some worked great but were too expensive; most did not work well enough in my system to warrant a change. The FetValve did. Is it the best amp I ever put in my system? Honestly, no, but I wasn't about to or able to pay close to $10K for the one that did! And just so I don't scare you off from the prospect, I turn my system on and never think of replacing the FetValve. (Unless it's with the possibility of an Ultra!)

Well ... I did it! Took the plunge. Ordered a Van Alstine Ultra Fet Valve 350 amp today. And I am GEEKED about it! Spoke with Frank to dicuss options and decided on the 350. Only issue is five weeks back log. So, five weeks of anticipation. Can't wait!

Best of luck. I just bought the one from gongos that was listed here. I actually recommend he try one but it was too expensive for him to keep. The way he describes the sound is like tonyptony. It's better than either.

The reason I bought it is because I have a Blue Circle BC 24 hybrid. If the AVA 550 is similar then I will be one happy camper. I totally agree that it's better than SS or a full tube amp when it comes to my Blue Circle. If it had more power I'd just keep it but 80wpc isn't enough.

Two people I know that heard the AVA 500 on similar speakers to mine describe the sound the way I'd describe the Blue Circle's sound. I'm sure that they're different but hopefully not too much, maybe I'll like it more maybe not. I've read the same type of description from others of the very clean and natural sound that is full and rich yet detailed which is exactly what I'm looking for.

You will have to let us know what you think of it. I doubt too many people would ever send them back.
