I heard it twice in Ypsilon systems with Ypsilons own speakers...really fantastic. It is one of the very few push/pull amps I have heard that is worth considering.
I still need to hear their big SET100 mono hybrids and their PSE300b amps.
For now I am having fun giving Diana a spin and the Ayon Crossfire III. Soon I will have Vulcan Evos as well to add to the mix as well as the new Auris preamp. Diana likes Thiel CS3.7s very much.
I am biased since many years ago we decided to only carry Lamm for our electronics and dropped all other lines. After nearly 30 years in this business and hearing many, many others we still believe Lamm electronics are the best and most natural sounding equipment that there is, bar none.
