Yes!!!!! MacDEF give them another chance, get a Perreaux, a cheap good amp for it, and try them again, and let us know later.
About the Headroom amps and the HD600, i have a concern, it's true that many members have talked about that in other threads and maybe it was a sad coincidence, and that doesn't mean that they did that on purpose, and I do not think that way neither, I do feel that they make pretty good amps, and if none of them match with the CD3000, is really sad, because they are even loosing many potential customers who could get their amps instead of looking to another places, but you have to agree with me that is a coincidence indeed, that all of the amps they make perfectly match with the HD600 (or the majority), and none of them, with the CD3000, OTOH also they carry the HD600, and they do not carry the CD3000, you have to agree with me that is a coincidence that could leave you thinking.....if you have not read those arguments made by Tyll before...
Now for other members that wants to know exactly how they sound, and do not want to listen or read those raves, you have to do the same I did, search, read, and ask, there is no other way, as an audition is very rare, unless in a meeting, and if is not hooked on the right amp, you get the wrong impression and opinion later, just search and read, this is the key, ask hirsch, mark, servinginecuador etc....members that have owned and extensivelly listen them with a lot of gear....
