I have heard the Aesthetix Callisto and I was not impressed. It actually has some harshness in the upper mids which is slight but still evident. Also, I found it to be surprisingly undynamic. I have not heard the Lamm L2, but did hear the L1. I compared my CAT Ultimate to the L1 in a system powered by Lamm amps and I prefered the CAT over the Lamm significantly. I would rate the Aesthetix as the worst of the three, although admittedly no head-to-head comparison was made between it and any of the other two.
Has anyone heard the new LAMM L2 preamp?
I presently own a pair of LAMM 1.1 monoblock amplifiers and am considering the purchase of a new preamp. Has anyone tried the new Lamm Referance L2 preamp in there systems? I am also considering the CAT ULTIMATE preamp which is my second choice and is far less money.Your help would be appreciated!
