The first thing to note is that the Job INT is made by Goldmund (we’re talking very high end audio) and is a Class AB amp vs the Peachtree which is a Class D amp. Many audiophiles will say that a Class AB amp sounds better, but Class D amps have come a long way and also sound very good. In general, speakers that are designed in Europe (UK), in my view, match better with amps designed in Europe. With that said, I would imagine that the Job maybe a better match for your KEFs. Of course the best thing would be to audition all both amps, but if you had to go blind, personally I would go with the Job and KEF match up. Btw, It a bit more expensive than the Job, but I think you own it to yourself to also check the Hegel H80. At the end of the day, trust your own ears.
