Heh, I'm still at work, and will be for a while
As soon as I get it home I'll hook up the new pre.
As to the original question, the DM Stratos and the AI are one of those combo's that just "work", not just a good match, but a GREAT match, IMO. If there was a flaw or weakness in the pairing of these two, my RM40's would let me know, post haste!
If you couldn't tell, I really like this combo. So much so, that I'm a bit skeptical that the Symphonic Line Erleuchtung is actually going to be a big improvement. Klause swears it will be, and I have no reason to doubt him, but dangit the system sounds so good right now!
Anyway, I can only afford to keep one of these 2 preamps, so if you see my AI up for sale in a couple of days, you'll know whether I thought the SL pre was better
