I tried a Blue Circle 21.1 preamp to go with it, but the sound was not very good at all. The same preamp with my MC-240 was okay. So I am wondering about useful preamps with this amp. I had a friend come over with a Bottlehead Foreplay which played very nice. Just hard to match up a preamp with, could that be transformer coupled problem?

I have had this for approx a year, the sound is good once you roll some "old stock" tubes to replace the chinese tubes which tend to be forward and lack the subtle details that vintage tubes have. I know a friend with a S45 Moth amp that shows the difference in quality though.

Thanks, Ron
