Anybody have some experience with Bedini amps?

Yes sir, the Bedini amps seem to fly way under the radar. I too concurr with Mr. Walsh on the little Bedini 25/25. My favourite of the vintage Bedini's, It truly makes beautiful music.
I too ran a pair of them into stacked quad 57's for years[1 channel per panel]. Although I am not certain it will drive the Shahinians.... I wouldn't be the least bit surprised if it did though? It certainly did a very credible job with a pair of acoustat 2+2's in an average sized room.
Perhaps one of their bigger amps may be more applicable though.
While I can't vouch for any of their later examples [never heard], I do remember their biggest amp in their line up at the time [the 250/250 class A] In fact it did share a lot of that beautiful 25/25-like voice,and more 25/25-esq than any of the other Bedini amplifiers back in the day.
Back when I was using the acoustat 2+2.... It was my preferred amplifier over the other class A designs from Krell, Classe[Dave Riech era] and the Threshold 400a.
Not sure how many were made or still in service out there, can't remember seeing one offered for sale but you might want to check with the Bedini company site or perhaps place an add in the "wanted to buy" here at Audiogon. Bedini still services, updates or rebuilds all their products. Best of luck! Cheers...david

Fabulous sounding amps(the 25/25 model).My pal had these powering stacked Quad EL 57's,with ribbon tweets between.
Very sweet,in the "best" sense.
Best of luck.

David, it WILL drive a pair of Obelisks. I ran a 25/25 into mine for years. Worked quite well, if not quite able to make them go to the highest SPLs. While I've moved up in both amps and speakers, I'm sorry I sold both.

Hi Tony. Good of you to post that, and I am not the least bit surprised. Considering what the early Bedini's typically sell for in todays resale market .... Surely has to be considered as the proverbial "NO BRAINER" buy relative to the pricing in todays hi end market place!

If you can find a 25/25 jump on it. I sold the Oblelisks to move to the Diapasons, and the little Bedini could drive them but honestly not well. After several years of using other Bedini gear I moved up (and I do consider it a move up) to an AVA FetValve Ultra 550. I consider this amp a head and shoulders improvement in driving my Shahinians over any amp I've heard in my system - including the Bedinis.
