Speaker Recs for McIntosh and Jupiter Combo?

price range?

Under $3000

You might want to look into some of the current model
Thiel speakers. I have an all McIntosh system except for my CD Player; and I'm using Thiel 3.5s - which sound better
than ever.
Some folks tend to classify Thiel speakers as being "too
bright". Quite frankly, I find them very revealing of
inadequate upstream sources. As you have a great CD player
and electronics; I think you might be pleasantly surprised
if you listen to some Thiels.

If you're looking for something perhaps temporary, or maybe even long term, when I was buying my McIntosh equipment the dealer hooked up a pair of PSB Stratus Bronze's, the cheapest of the Stratus series, apologizing that that was the best he had just then and admitting that they would not compare to my B&W Matrix 802's. But I was extremely impressed with the combination - very pleasing midrange and mid bass, and pretty good all around. Ebay sells loads of these. Many argue the Silver i's are the best of all three. I had the Gold's in my system (with the Mac) for a long time, and thoroughly enjoyed it. For the money, the bronze is really a good value though.
