From what I've read about the amp it is excellent for the $ but can be lacking a bit in body more neutral side. It might mate well with something a bit mellow like a Warfdale. Maybe a Lyntons. Also from personal experience, CSS Criton 1D is an excellent speaker of that type if you want to make a pair from a kit. One more choice foe a speaker that is laid back consider a Dynaudio Evoke 10 or 20. Maybe rustle up a used pair. I'v owned the last two so it's personal experience.
Speaker matching for Audiolab 6000A
Shopping for some monitors that match well with Audiolab 6000A integrated amp. Recall reading somewhere this amp not the last word in grunt, and difficult to drive speakers should be avoided. Deep bass not necessary as the speakers will likely be supplemented with a subwoofer. Budget up to about a grand, but much less is great if the match is right.
