Bsimpson, you're talking about equipment that is at, or near 50 years old.
What would anybody expect from such? Who was around back then to compare, Levinson, Krell, ARC, Pass Labs, Accuphase, Burmester, etc etc.
It's like you are saying, I onwed a 40 year old Sansui 7 Reciever, and was not impressed with it driving my Wilson Grand Slamms.
Lot's of snobbsh "esoteric" BS being pedalled around here for over 12 straight years.
Go audition an MC-452, or a pair of MC-601's, MC-2301's then tell us what you think?
