Devilboy,
I had the Momentum stereo amp and yes it was VERY good, one of the best amps I have had and I have heard. I prefer my CJ ART monos over everything. There is no contest against my CJ ART amps. CJ ART monos are stunning.
Believe it or not, the Job is better in some ways and not as good in some ways compared all my other solid state amps. Yes, compared to those mentioned. This is my opinion and not fact. If you consider the price difference and the amount of power you need (meaning if the Job has enough power), give me the Job 225 and I am done solid state amp-wise. After all, it is a baby Goldmund. Having gone back and forth with tubes and solid state, tubes give me more enjoyment. Tubes over the Job? No. The Job over other solid state? Yes.
My new Job arrives Monday. I am happy.
