Mark Levinson 29, 27.5...

I have owned a dozen power amps. Let's keep this specific. Just talking amps not anything else. Cables and the preamp and source, the speakers especially matter of course a lot. I'm specifically just talking power amplifiers. The amplifiers I have liked the most were my ML 29 and 27.5. I upgraded to three other brands one by one of other power amps. For me, for my system, I'm now convinced the 23.5 will be the best. Best balanced output 20-20K dynamic, deep, fast. Please advise me what amp you LOVE with your floor standing loudspeakers and top shelf sources and preamps and interconnects and power cables etc. I like the rest of my system. I tried to get some more SPL by upgrading my ML 27.5 100Watt and the three more powerful amps I tried were sorely disappointing. The two objections I see are what were the three amps and it's subjective if you like ML...

What is the best amp? I don't want to disparage the competition but the three amps I used were more wattage, more expensive and current modern successful brands.

I will enjoy comparing a 23.5 to all the other power amps I've had but there have to be a dozen super better, what are they, I want one ASAP thx!
