Thanx joekapahulu, I know about Audio Classics. Several years ago I've bought from them Mac MC275 and it was in like new condition. I used it for quite some time but due to my listening habits came to conclusion that I prefer SS power amp. I made this switch and honestly speaking quite satisfied with results, but that ansatiable audio bug of ours force me to look for smth better, and Mac SS looks like a first natural choice.
