@rick81 Listening to the LCD-2s right now with the AMP1 in high gain. They are OK together. The music isn't as controlled as I would like. The AMP1 drives the LCD-2 but not really well in my opinion. I was listening to Hello by Adele and that sounded flabby and I didn't hear really good separation of instruments.
I'm listening to Taboo by Skinny Hightower and Andrew Hawkley now. Much butter sounding but still not as controlled as it should be. So not a terrible pairing but you can do better.
I have the AMP3 but I don't have an adapter for 2.5mm TRRS for my LCD-2 cable. The AMP3 may do better with the LCD-2.
