Seems like there are loads of ABX listening tests (Carver Challenge, etc) which tell us there is no audible difference between any amps which deliver sound at your top listening levels within their design limits. Any particular choice of amplifier above a basic good design (about $400 seems to be enough) would be justified only if you deliberately seek some distortion type of your choice.

Yea, about any amp above 400.00 will work. LOL That is 1990s tech, along with the flat earthers (fuse and cables make no difference crowd).

When folks quote "Blind test", Including the name "Carver", BS!!

It’s real obvious you don’t know too much about Bob Carver or you wouldn’t SAY your quoting him. That guy is his own man, and changed with the times just like everyone else, who is still in business.

Either you change, or start working for someone else.. The audiophile community would have put him out of business along with ALL the other Amp companies that have gone by the wayside.. That guy pushed a lot of cool ideas, BUT was able to tell the difference in sound quality, by changing a 50 cent part. Even Mcintosh changed the stupid policy of "Cable don’t matter" 20+ years ago.. BUT people quote from the 60-70s. KEEP UP!!!

No good treatment for cancer back then either, there sure are some good treatment now... Which articles do you read? Mustard gas treatment with radiation, or todays options.. I know what I would chose...

His idea that it doesn’t cost a fortune to voice or change the voicing of a product is his greatest asset, THAT is what Bob Carver was known for.

BTW so was Mr Nelson Pass. NEITHER were limited by folks telling them what the book says or what "THEY" can or can’t do. Brother/sisters they were and still are the Chuck Yeager’s of the Amp and Audiophile world..

Not a good idea to quote 40 year old STUFF, from a 17 year old threads..

Keep up OR enjoy your 400.00 amp... BTW I have quite a few around 400.00 class ds. Perfect for the right application..

My issue is no suggested retail price on OPs amps.

NO 20 - 40k amps or 15-20k cables either, total BS too.

I'm a big fan of Musical Fidelity's products. However you have what I think is a decent amp. There may be a change by swapping amps but the change might be very small and only at the frequency extremes. If I was looking for a change I would be looking at the pre-amp. What pre-amp and source are you using?
