I have used Meier Classic, WA6SE, V200 and also Soloist with the LCD2.2, not sure if they are considered "high-end".
But i still prefer the LCD2.2 with O2/ ODAC.
Thanks for clearing the specs up..
PS: your msg is not offensive, but i do admire your passion for Toxic Cables..
Wow, you prefer the O2 over all of those amps SQ wise? Could you please do a quick comparison between the Soloist and the O2?
