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.

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.

I found that a Nord Purifi Class D amp at 250wpc at 8ohms was a great match for my ML Vantage speakers, Funnily enough when I bought Sonus Faber Sonetto V speakers the Class D did not work as well as a Rogue ST90 with KT120 tubes. My guess is that the Conrad Johnson amp is too rolled off at the top end and is sucking the life out of the MLs.

For a preamp, I'm using the Topping Pre90. 130 dB S/N! Amazing clarity. I think you would be happy with it too."
You might be happy until it stops functioning.
