Never heard the Belles amp, though I have read the Pass Labs amps are on another level. Currently own a Pass X150 one of the older ones, but see no reason to upgrade with my Supratek preamp.
I had a Modwright preamp before the Supratek, comparable with a different flavor. I would think the Modwright would pair well with Pass
go for the .5 or .8 series which are suppose to be a little warmer.
