Hi Shrink, I have been a bit slow to post but it's the Audiolab Q + 2Ms upgrade that I had a bit of experience with.. First, though, I'd need to say that I went right up the standard Audiolab ladder for three reasons, the last 2 probably being more valid than the first which was of course the dreaded What HiFi reference system.. The second reason was a lazy, more of the same, + synergy approach. The third was financial and tactical: I found it very easy, living in London, to buy and sell Audiolab gear s/h and without much punishment from depreciation. I bought the 8000Ms for ?700 about 5 years ago and easily sold them on 2 years back for ?600. Perhaps there WAS a virtue in the old What HiFi push after all...
Anyway - like you - I had the Q and definitely rated it above the C. The switchable gain was a nice bonus too. Then, and with Audio Synthesis DAX both introducing me to the brand and giving my digital replay a more pleasantly analoguey feel, up came the chance of an Audio Synthesis Passion Ultimate passive pre-amp.
I wasn't at all sure what I was getting into especially when I was given some verdicts on inductance and the length of the interconnects which all went above my hopelessly non-technical cranium. But... it was so much better. The first thing that I recall standing out was the channel separation in a far wider sound-stage. After that it was clear too that the Q was a bit sluggish. However - I do need to point out that my set-up location is not one which allows easy a/b comparison. The decision, though, was easy. The Passion came from Larkrise who sadly no longer posts here but who kindly allowed me an approval period longer than I needed.
Anyways - I'm still there with a Passion and a Desire Decade (non-black gate) Power amp and can't say I miss the Audiolab stuff too much.
Just a few thoughts for you... and good luck with the hunt.
