Anyone with info on vintage Muse 160 power amp

Hello all. I bought the Muse 160 power amp just going off the few older reviews that I've read and must say that I agree that it is a fine sounding unit. Paired with a MF Pre24 CD/Pre into ADS 1230's the system sounds a little 'thick' in the mids but not by much. Does anyone have any info or experience of this amp and what 'synergizes' (???) with it. Thanks, Mike.
I Have the model 160, have used it with the b&k pre, moscode pre and threshold pre, works beautifully sounds awesome, have the manual too
