Hello Vad58, just curious if you ever got the mc 275 vi? I have never heard tubes in person but love what they got to offer sound wise except the heat of course. I have an opportunity to buy a pair of mc275 vi and run them in mono set up. I currently own Pass Labs 250.8 and I love the sound they create in my set up with Martin Logans Summit X and I was told tubes will get me even better sound.
