With such high efficiency speakers it would be soooo tempting to go pure Class A. The cleanest and quietest signal will reap the most reward. 102db efficiency indicates the first watts are the ones you will be really using so might as well have the best.  Some of the folks here can do the math but Class A will IMHO give you the best sound possible out of those Cornwalls.  30 watts of Class A should give you around 104db @ 20 ft away.  But if I had to choose from your list, the JC1+ since the first 25 are class A .  The Classe only gives around 3 watts of Class A  I think. Good Luck. 
Bingo Lord.....that was my choice but I was being polite and trying to answer your list. ;)
Everyone has given great input on this thread. I checked my calculator again and imagined in a garage you would be no more than 15' from those speakers at any given time. 3 watts is going to produce  a hard rocking 96.6 dB SPL with 2 speakers.  At 10 foot away this jumps to 100.1 dB. Watts are definitely not your issue. When I crank my system up, an SPL of 80db is all I want because I'm not interested in damaging my hearing and that is only for a song or two.   


Respectfully, Arctic...that would be true with Magnepan for example,  not with OP's speakers. The current & capacitance supplied by all the above mentioned amps will not clip before your ears quit on you.  It is a different beast. Hence the reason why so many choose Tube amplifiers. Be assured the power supplies on the Pass Labs amps are far beyond adequate.  Watts are not the right measurement.  Cheers.
