Anybody have some experience with Bedini amps?

I have a Bedini 25/25 that I love powering a pair of Obelisks to the level where I once thought I would blow the woofer drivers — the sound was that enormous. I couldn’t believe the sound coming from what are really rather small speakers. Vasken Shahenian assured me I could not damage the Obelisks with the 25/25 since the speakers were rated to 400 watts capable. Glad I found this group - I have a MAJOR ASK - my 25/25 has been repaired 2x here in Las Vegas, where I live, and has lost its magical bass transparency and speed (now sounds thick and muddy at the low end). The tech said it was fixed to full frequency spec on his test gear, but I can tell you it does not have that holographic musicality. CAN ANYONE HERE direct me to someone who knew John Bedini and knows how to restore a Bedini 25/25 as if John were doing the work? I was emailing John prior to Gary passing, and John passed soon after Gary. Broke my heart. I keep my 25/25 not only because it is great but because I have known John and Gary Bedini personally since the 1980’s-90’s. So if I can restore the 25/25, I would be delighted and feel I honored John in the repair. Currently, it is less than, what we are all recognizing as, the Bedini Magic of the 25/25 (which Gary once told me was their most musical amplifier).

@stereotwo  I agree about the Bedini Shaenian system,. Pure JOY.
