Any Problems with Conrad Johnson Premier 140?


I see a surprising number of Premier 140's available on the used market. Is this indicative of problems with this fairly recent offering from C-J? The amp sounds very interesting to me for running my Totem Mani-2's, but I don't need to court trouble. (Been down that road with ARC Classic 120's!)

Why don't you e-mail some of the sellers after they have sold their stuff. I've done this as research if I have a similar concern. Folks are a little more forthcoming after they have money in their hands and the gear is gone. For the most part though, people just like to try different things. Nothing wrong with the items but boredom.

Cheers,
John
Just slightly related;I have a set of the 8XS mono blocks. I read some hype about this 140 being CJs best ever ? I wonder ?
I had the 140 in my system for an extended audition period. I found the amp quite musicial but decided to keep looking. They are big and generate quite a bit of heat.
I too am curious but I suspect it is just what robert8409 mentions. There is alot of heat generated with large tube power amps on top of the maintenence issues with the power tubes.
