Mark Levinson 531H vs Classe CT-M300


Anyone know both Mark Levinson 531H and Classe CT-M300? They are newer mono amp, 300W at 8 Ohm, same price range. My speaker is B&W 802D. I need to choose one of them.

I have the Mark Levinson 532H amps bi-amped, one amp per speaker and they sound very musical. I highly recommend them.
