@davenrk it seems you have mistakenly drawn the conclusion that tubes are generally not transparent, and detailed. I find them more transparent and detailed than any ss amp. It's like taking the heavy blanket off the speaker.
So any of the highly rated tubes are rated that way for detail and transparency.
I think "warmth" is often a euphemism for "less harsh". People who have a harsh system try to add something to reduce the harshness. and if the harshness is caused by their pre, and they put a tube pre in, they think that tubes are less harsh, they are really just more accurate.
BTW, this is a 4+ yr old thread.
