I heard a pair of M60s many years back, can't really comment with any meaningful comparison with the later Silver 88, compatable with the kt150 tubes and what I currently use. The Silver 88 is a most exceptional amp with nada a one irritant that fatigues over time. I never heard a Quicksilver I didn't like. They really are an amazing value in tube amplification.
I agree with tooblue, give Mike Sanders a call. He is direct and a no bs guy. He'll give you his honest opinion.
