Hello,
A local dealer uses a Conrad Johnson tube pre amp with the 2500a solid state amp on the JM lab speakers or one of the tube amps. Currently I'm using a Herron tube pre amp and the Herron M150 mono solid state amps with my JM Lab Mini Utopia speakers. I think the sound is very musical with a low and tight bottom end and excellent mid and uppper end. Some have said the JM lab speakers can sound a little bright and/or thin so picking a musical source and amplification really helps. Some folks have recommended staying away from the Pass and Plinius gear with these speakers but or course those are just opinions and I don't have any first hand experience with those two companies.
