Thanks, folks! The MF and Simaudio are, indeed, absolutely wonderful! The time I spent with the MF was with a pair of Paradigm (forget model number but somewhere around 4K or 5K retail at the time), the same Marantz CD player I have but currently using as a transport and an outstanding Marantz TT-15S1 turntable.
The Simaudio I spent time with involved the same CD player, a pair of Martin Logan Motion 60XTi and then a pair of GoldenEar Triton 2.
Gano, when you say the Simaudio is "hard to match" what do you mean, exactly? That puppy has such a massive current supply, it had no difficulty driving the ML to their fullest capabilities. However, I was wondering how well it would do with speakers that live in the 4 Ohm zone most of the time. Even though the ML are rated as a 4 Ohm design, some reviewers think it's really a 6 Ohm speaker.
