I am in the process of doing that. I need to give it some time cause I don't think I have "trained ears." I have listened to Simon and Garfunkel box set from late 90's - slightly more clear and nicer clear bass than the M3s. Rameau SACD with Pinnock and Podger from Channel Classics - again - slightly nicer. Like the M3s but with more detail and smoother mid and treble (surprise surprise).

But I need to listen for a while to say definitively. I will hook up the M3s again on Sunday to A/B them on stereo setting.

As I say - I don't really think I know what I am hearing for sure yet - over time I think I will be more certain.

M22s, QS4s, M2 center, Hsu stf-1.
