Good amp for ATC speakers

Thanks for your response about the Herron amp. They look like fine amps but actual detailed reviews are pretty much nonexistent. If you used these yourself, can you comment further on their sound? I have a low power Pass class A amp and love the resolution but feels it lacks a bit of "slam" for the type of music I prefer. Thanks.

Well I got the new SCM19s and mated them with my 30 watt Pass. In my small listening space they work ok, although in some cases the volume is now pushed to about 75%. I would look for more power down the road, but for now this will be fine.

Thanks for the amp tips, all look interesting and will be up for consideration when the time comes.
