If anyone else is thinking of buying a JOB 225, I can report that despite the problems I've had with it, the amp sounds unbelievable for the money. I don't remember hearing an amp with high-frequency response like the JOB's. To my ear, the JOB sounds more transparent than similarly powerful Accuphase, Rowland, McIntosh, Quad, and Simaudio equipment that I've heard. I wish I could compare it to Spectral gear, but I've never had the opportunity to hear a Spectral amp.
When I was having my Gryphon Antileon in for repair, I was lent an old Golmund amp while I waited...good service from my local dealer. That old Golmund taught me a lot about pure treble. Coming off CJ MV60 and Antileon, my reference was to the darker side...but the Goldmund was not just far more illuminated in the treble, but that treble was incredibly pure.
When the chance came to sell on the Gryphon Antileon and take a second hand Geyphon Colosseum, I gladly did it, and the area of greatest improvement was in this area. More than a match for the older Goldmund in treble with everything I already enjoyed about Gryphon generally.
But that old Goldmund was a remarkable piece in the high frequency.
