Powering Acoustic Zen Adagios

I am about to purchase AZ Adagios for my living room (normal size) and looking for something to power them up. I have a DAC with volume control, so it can be either power or integrated.
I want an amp that runs relatively cool (my previous one was a behemoth running 80W in class A and producing tons of heat) so pure class A and tube based output stage are out of the questions.

I am limited on budget so focusing on used equipment, and have narrowed down the list to the following contenders:
1. Teddy Pardo 100mb monoblocks (the only ones within my budget I've heard so far with these speakers)
2. Mcintosh MC202 (power)
2. Leema Acoustics Tucana (I)
3. McCormack HT3 (much cheaper than the other alternatives)
.4 Mcintosh MC 2125 integrated (questionable condition, but relatively on the cheap side of the price scale)
5. Krell Kav 250a 2 or Krell Kav 250a 3 (similar pricing)

I need your advice to narrow down the list to the top 2-3 candidates for listening audiotions.
