LP70s v. Classic 60

[bgiliberti]

Ok, maybe I misread. Jeff was referring to LP70 vs LP140 monoblocks. I thought that the LP275 was the same design as these, more like two LP140s combined. That's more or less what I gather from the CJ website. I don't know enough about the LP275 to say if I was over extrapolating from the LP70 vs LP140 comparison. Here is the thread, with excerpts.

C-J LP140Ms To be or not to be? That is the question - AudioAficionado.org

That will offer a much bigger performance gain than going from an LP70 to a pair of LP140's. ...If you talk to Lew and Bill they will tell you that the three amplifiers are all basically the same, other than larger output stages, with more tubes and transformers that are equipped to handle the additional power. The quality of amplification is the same across the range.
