Integrated SS amps - Luxman vs. Simaudio Moon?

What Verity speakers are you thinking of? I had Fidelios with a Pass INT-150 and thought it was very good, but not exceptional. I've heard the Luxman, and while it runs very hot (not my cup of tea) it sounds phenomenal--very natural. I haven't heard it with Verity, but I do imagine this would be a good combination. Verity is easy to drive, so there are a lot of lower-power integrateds you can look at. The i-7 is very good, but maybe a little too analytical for verity, but again, I don't know which verity's you're thinking of. I don't know anything about the 700i.

Pass has a new INT-30A which is based off the X30.5, which is 30 watts of class A. That might be an interesting thing to audition.

If you're deciding between just luxman and sim, I would say luxman.

I would personally pick Verity over B&W's any day. I am a fan of building systems around speakers, and I think Verity makes very good speakers that respond well to a variety of amplification (tubes, class A, beefy AB, etc) and are life-like natural while still being neutral.

A big factor will be your room, as unless your dealer will allow you to audition at home, you're not going to gain the ultimate insight into a possible system by listening at a dealers. I've purchased from dealers, from friends, and on Audigon. I'm the kind of guy who likes to play around and tweak my system until I feel it's right, or I can settle in and listen (usually how I know I'm onto something). I don't mind buying and reselling if I have to, and I get to sample a lot of equipment that way. If your idea is to get everything and be done, then more research is required, or you have to find a dealer you trust, and let them put together a system you can try at home.

Do you have a particular listening preference? My feeling is that the kind of person who listens to B&W and Bryston wouldn't necessarily be pleased with a verity/luxman system and vice-versa.

What's the room size? That will be a big part of which speakers you choose.

The best thing to do is call up Verity. I have a sneaking suspicion the Rienzi's will be too small for your room. I had the Fidelios in a 17 x 20 room and while they sounded good, they did sound small. If you are buying new and can afford good speakers, then take your time. I've spoken to Verity before and they're straightforward and helpful. Since you mentioned the Leonore, I'd investigate them. The 509u doesn't doesn't have a remote, in case you need one.

Other speakers you may want to investigate: Devore Silverback Reference or something from Audio Physic. If you can handle the heat of the Luxman, then go for it. I thought it was stellar.

I'm going to reiterate my above post that given your room size, the Rienzi's may sound too small. The new Leonore is probably more appropriate. Just my feeling, and could be wrong.
