What about the Belles SA-100?

I guess you are right that marketing may play a role here; unknown, unloved. When I was looking for a new amp my dealer suggested to audition the Belles SA-30, even while my speakers have a difficult load. I decided for the SA-100 as that was the one available for a demo while I was visiting him. I instantly loved it, though it took quite a while to run in the amp. And I still have the feeling that it is getting better every day. So similar to your experiences with the SA-30, this is phenomenally good amplifier, second to none. It is a true gem.
Not sure about the politics, but perhaps these amps are too cheap...?

My 150a ref v2 took roughly 850 hours to reach it's peak. As good as it was about every week I was happily suprised that new nuances of sound for a more positive and natural presentation would rear it beautiful head.I don't know if most wait long enough on these to rear them at their best. But from about 200 hours mine was about 90%-95% there. And at that point even the amp was a stellar performer. I have had a few models of audio research, jeff rowland, and listened to many others in well broken in systems bat, cj, threshold and others and with the belles it is right there with these others or very very close in a properly matched system. Now I would like to try the sa 30 or sa 100. Nice to hear from you guys these amps also are something special.

It is interesting what you are saying. Earlier I have had JR monoblocks, but as good as these were, they could not even stand in the shadow of the Belles. The SA-100 is such an open window for every kind of music. But also needs a proper match and time to open up to reach its peak. If you have the opportunity to audition one, then you should.

I agree. Thanks Noortje.
