I think perhaps the biggest problem with small SE sand amps today will be speaker efficiency!! "In auld days" speakers were routinely 95 dB or so. Today a 12" speaker can handle 1000 watts RMS ( or so it is claimed) and maybe 82 dB/watt. That equates to some very big heatsinks !!!! not to mention battery grade cable to handle the idle current.

Just my take
