Belles research?

Thanks, good to know.

Phusis - Thanks for the link, very much appreciated.

Got my SA-30 this week, at this moment listening to Idle Moments ( Grant Green )
Sounds wonderful and I am using the pre out on my old solid state intergraded amp! Very happy also that it is sounding great on low volume.
Looking forward getting a Supratek pre to give the Belles some quality.
The amp oases quality, but it does get quite warm, so good ventilation is paramount.
Very happy with it so far.

SWEET!  Wonderful amplifier.  All Class A amps run very hot.  IMHO, the hotter it runs, the better it will sound.

Mick makes a GREAT preamp.  Should mate very well with the SA-30.

You picked some very, very nice gear...
