Music with differences between class A and class D amplifiers


Hello,

I own an ATI AT523NC Class D amplifier and recently purchased a Schiit Aegir Class A amplifier to compare two different approaches to amplification. I've been switching them back and forth all day but can't hear any difference at all between the two in my music. The good news is, both of them sound great.

Does anyone have any suggestions for music that sounded clearly different between their Class A and Class D amplifiers? If so, I would appreciate some pointers on what to listen for.

My setup is PC (Roon) -> Matrix Audio X-Sabre Pro DAC -> Schiit Freya Plus Pre-Amp -> Amplifier -> KEF LS50s.

Thank you for your help.

Thank you Al, I appreciate the help. Will take a listen tonight, happy holidays to you as well!
From what I have read in other discussions as well as publications, LS50s are quite sensitive to amplification. When I include a crappy AVR in my listening test, the treble noticeably sounds more congested than either of the other amplifiers.
Thanks George. Yes, this is a small room near field setup where theoretically the first few watts are the most important.
