The Audiolab amps definatly need to be partnered with speakers that have some character, I have a rack of Audiolab 8000M's and use them to drive Mission 753F and its a really good match imho. Its probably not that surprising though, as before Mission was bought by IAG, they were pretty much designed to be driven with their sister company (cyrus) amps. And like the Audiolabs, the Cyrus Amps dont add any real character to the music. They are very neutral amps, which is fine if your pairing them with speakers that have chararacter. I've tried the Audiolabs with some old big tannoys, and it was pretty entertaining, but I found the tannoys to be a little too boxy in the mid range. Still good party speakers though.
IMHO its a lot easier to get a happy musical system from Audiolab amps and well matched speakers, than trying to find an amp that will add character/personality to Monitor Audios

... Speakers are in my opinion where the real tone of the sound is set.
Of the Audiolab range the 8000A, C/P and M's are the most forgiving models, and the 8000S, PX, and MX's are the most sterile models. But they are all lean/neutral designs.
Personally I love my Audiolabs, but I wouldnt want to partner them with bright speakers, or source. I had an arcam CD player hooked up to the system once, and it was so over the top bright it was very tiring after about 10 minutes listening.
