Best Speakers to match Ayre V-1xe and K-1xe

I would be shocked if you found that Ayre front end combo insufficient to drive the C4's - that's a stout amp.

You don't highlight your room size or listening habits. I can only comment on the Dyns - I've owned the C2's and C4's, amongst several other models - but have never heard some of the others or only at shows.

If you have a medium sized room (say 15x20 or smaller), the C2's are a wonderful speaker and the Ayre front-end would be a great match.

If you have a large room, the C4's are a much better choice and, again, I think would mate very well with the Ayre gear. When I moved my C2's from a medium room to a very large room, I wasn't nearly as satisfied. The C4's are really in a whole other league when you get into "big" music - rock, large-scale orchestral, etc. - but really need the room to support them.

If you've heard all the speakers on your list, hopefully you've formed an opinion of which you liked best, given the different conditions under which you heard them. I think the Ayre gear will compliment the sound of all of the speakers you mention, not change the character, so if there was a clear favorite from your auditions, I'd think you'd be safe to go with that.

My current setup is the Ayre models you mention paired with the Dynaudio Sapphires. The Ayre's are completely new in my environment, and it's all set up in a new room / house. Early returns are excellent :-) I really like the C4 at $9000 or so used, which seems to be what they go for, but if money isn't as valuable to you as keeping the wife happy, the Sapphires are considerably more wife-friendly, and they're less than the WP8's.

Another question - is your K1xe equipped with the phono stage and do you play vinyl?

I think the VPI Scoutmaster is an excellent table to try - it's obviously a very popular line, there is a lot of support for it, and it is widely reviewed positively.

The Sapphires are less, retail, than the C4's, but the C4's are available used for under $10K and the only way to get the Sapphires at this point is to pay their retail price of $16.5K. It's a great litmus test for the significant other, though - they currently cost more to obtain, but they are a far better looking speaker for the domestic environment. I like the looks of the C4, but it is very large.
