This amp is one that I learned of only through audio Web sites. Been using one about a week. Preamp is passive/active (no gain in either mode) Schitt Saga with 6sn7 and resister switched volume control. It is a very nice sounding and relatively affordable combo.The sound of instruments timbre is what I think the 225 amp does best. It has good detail and bass, but my Rega elicit integrated (2nd version) edges it out on bass. The sound of piano, violin, acoustic guitar and vocals is spot on with the Job 225, dispelling any hardness, harshness or etch. The overall sonic picture is somewhere between B & K st 1400 and Pass labs Aleph 30 amps I've owned, if that makes any sense.....all 3 are well regarded Mos-fet based amps, there's something I prefer about mos-fets versus bipolar transistors, maybe more "tube" like?
It's a really nice sounding amp for the money. The term "giant killer" gets thrown around so much that after some time in the hobby one kind of gets anesthetized and wary of it. I wasn't expecting a 1700 dollar miracle when I ordered the Job, only to get a nice sounding, musical Mos-fet amp, and I think the Job 225 certainly is.
