First Watt with KEF LS50s

I think I would use only the balanced input, perhaps with a Goldpoint to switch between an Oppo BDP 105 and Sony HAP-Z1ES, both of which sound better with balanced output.  It would be nice to have an HDMI option, but HDMI seems a can of worms small companies fear to open, although Bryston seems to have done HDMI pretty well in my SP3.

If you mean a Halo Integrated amp, the answer is no.  I've used both an A 21 and A23 to drive the LS50s, and much prefer the A 21, but it's too large for the cabinet I want to use so I sold it last night.  Richard Schram tells me the sound with Halo Integrated should be closer to that with of an A 21 than A 23, so that's a strong recommendation.

This is a secondary setup that's in use most of the day, so a low energy Class D amp could be attractive.  My main setup uses three JC 1 monoblocks for LCR and two A 23s for surrounds.  I have three Proceed Amp 2s sitting on a shelf that as I recall, are fine amps, but an integrated or Class D is an attractive idea.

mapman, the Reno folks who sell First Watt concur that it's not a suitable pairing.  (I think I got carried away by how well the pair of 20-watt Cary CAD 573 SE tube monoblocks sound with the LS50s.) I sold the Parasound A 21 last night and will use a Proceed Amp 2s until I decide which way to go, i.e., a Halo Integrated or something else.  Which Class D amp would you suggest?
