What's a good amp to pair with SF Grd Piano Home

As you're looking for a good match for the 38, too, I would recommend ML334.
Otherwise, I would propose a change in the pre: to these ears, the ML amp -- say the 334 -- outclasses the pre. You may wish to reconsider an integrated, though, if the investment for a pre+amp combo is too high....

Truth is, Hammer, many amps will drive these speakers so, it all boils down to what you're looking for! (Any tips? Music you listen to, rest of system, what you like sonically...?)

Taking a shot in the dark while remembering these speakers' nice mids & upper bass, the following integrateds could a nice job: (no order)
YBA passion integre (SS)
Jadis Defy (tube)
S-Line RG14
S Faber's own integrated (whatever it's called)
Rowland's integrated
Pathos towers
... and many others. Also bigger pre-amp combos of course.

More info will help! Cheers
