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.

"

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.

I drove Quads with CJ Premier 12xs with great success for many years. Not the same setup as you but very similar.  Pr12’s use EL34’s and have 60 watts per side just like your amp.  So I don’t believe the problem is your amp.  It should be driving those speakers just fine particularly since they have powered subs.  Make sure your speakers are at least 2-3 ft. off the wall.  Further is better.  Other than that sorry I really don’t have any other suggestions other than trying the CJ Owners Group.  Lots of CJ owners there that might be able to help.

I can’t help you with any specific experience with your set up but my objectives are similar - rich fulfilling sound with detail and dynamics with max 85dB peaks.

I’m there and very happy - good luck - what you are after makes sense and is achievable.

Why is no one talking about the equal loudness effect?  If the OP has separates or a monitor loop in their preamp, add a Schiit Lokius and dial in a contour that suits the desired listening level.  Easy to tweak and sonically neutral, especially at low volumes.

Doesn't sound like an amplifier issue at all. If you are not getting all the dynamics you expect except at higher volumes that sounds like you need some EQ, speaker placement, etc. Someone with hearing issues, known or unknown, may need EQ tweaks and not power.
