No one else seems to be responding, so, while I can't directly answer your questions, perhaps I can provide some directional input. I have the Gaincard S -- 50 watt version. It replaced an ARC VT 100 Mk. II, largely for heat and space reasons, and I don't think I've lost anything (gains in rhythm and pacing balance some loss in soundstage depth.) I'm driving the ProAc 2.5's with it. They are fairly insensitive, at around 86 db. The Gaincard plays as loud as I can stand, in my rather small listening room. I believe 47 Labs has a 30-day trial period. Hope this helps.
