Lucky guy! I have two pairs of Type A's (AII & AIII). I'm currently running the AII's as the III's need surrounds & I haven't gotten around to it. The AII's had new surrounds about 6 months before I got them (now 5 years back). I don't find the base thick/slow at all. Others have heard them and never suggested any base issues.
My power is a DNA-1(bi-wired). I also run a ACI TitanII sub.
You need more power & some break-in time on the woofers. When I first got mine I ran them for a short time with 60 tube watts..sounded nice, but not enough power. As for placement..I've played around with mine quite a bit and now haven't changed the setup for a couple years. Mine sit on 1.25 inch thick slate slabs that sit on top of carpet(this tightened up things up when I made the change from sittng on carpet). They are tilted in to be face-on with the listening position. One rear corner is about 18-20 inches off the front wall, the other corner is maybe 30 inches?? off the wall??..I'd have to measure(tonight). I'll check the side wall distance also.
My listening position is on a balcony over a great room (no wall behind me, speakers are set up on the long wall of a 13 x 16 foot space). My ears sit on one corner of a 103 inch equilateral triangle...I only discovered this after extensive adjustment until the sound was right..I then measured and 103 inches is where the center of the mids sat from me & from each other...go figure.
I've seen a number of posts that say the speakers should be parallel to the front wall and about a foot off...all the research I've done indcates this isn't the case..for me. The bass gets better with them off the wall a bit..too far and it drops off.
Also..with anything better than an average recording, if you can hear sound localized to the speakers, then you don't have them set up right, yet. Mine disappear into the soundstage with nearly any recording.
