Best amplifier for low to moderate listening levels

My system consists of Martin Logan 11A's, Conrad Johnson Classic 62 (60 watt per channel), Rogue Preamp, Lumin U2 mini streamer, and a Chord Qutest DAC. I realize that a high sensitivity speaker in the mid 90's for example would allow the use of a lower powered amplifier. I just purchased the Martin Logans 11A's one year ago and am not looking to get rid of them so quickly, not to mention the financial loss. Is anybody from the school that more power will bring a speaker to life even at low to moderate listening levels. I typically listen at 65dbs with 70DB peaks. I have listened at low levels and do not get the dynamics until the volume is turned too high for my ears. Any amps recommended that will mate well with the Martin Logans and maximize their sound. I know the speaker is a tough load to drive as the impedance drops below 2 ohms. I was thinking a high current amplifier (where power doubles when you drop from 8 ohms to 4 ohms. This only applies to solid state. My budget would be up to $10,000.00, but I would have to have a home audition before to avoid another mistake. Would a better DAC help in this regard? In short, I am trying to get this right, but its almost like I am operating in a vacuum. Difficult to obtain unbiased advice.  Thank you.

I can’t say that it is strictly the amount of power. Two amps with same power rating often sound different. I have a recommendation for you that may seem too inexpensive. I recommend the Martin Logan Forte amp (with ARC room correction). I have used this amp and continue to be surprised how it can take speakers that are not ML and impart that huge, clean, electrostatic type soundstage you get from an ML speaker. I absolutely love this amp. Don’t let the low price fool you (on sale at 60% off), it should be a perfect match. ARC will dial that amp in for your listening room at any volume:

I listen at similar levels on low sensitivity speakers and am currently auditioning new preamplifiers. I have noticed a difference between preamps in their ability to bring life to the music at lower levels. My point is, don’t focus solely on the power amp, maybe a different preamp could improve low volume performance.

I am very happy with a PS Audio S300 amp (300W/ch/4 ohms, stable to 2 ohms) driving the mids and tweeters, and a pair of PS Audio M1200 monoblocks (1200W/4 ohms, stable to 2 ohms) driving the woofers of my B&W 803 D3.

I think you would be very happy with them.

For a preamp, I'm using the Topping Pre90. 130 dB S/N! Amazing clarity.

I think you would be happy with it too.

It may be time to experiment with speaker placement (closer to the front wall) and seating position (closer to the speakers).  Possibly increase the toe-in, also.
