Looking for Speaker Recommendations

I would suggest the Rockport Atria.  When I was upgrading my speakers I listened to the Sabrina’s as well. For me the Rockports were just more musical and natural. I liked to them so much I bit the bullet and bouts Aviors

Fyne speakers might be a good choice, but be sure to go for the F700 series or the SP models in the 500 series.  They are made in Scotland and have great sound—92 db sensitivity and great imaging and sound stage.  I have the F702s driven by Rogue Audio RP-1 tube preamp and Benchmark AHB power amp.

I've gotta +1 for Spatial Audio Labs. I have X5s. It takes no power to drive them beautifully - I am using a 2a3 SET amp. A couple months ago I spent a few hours at the Pacific Audio Fest in Seattle. To my ears, NOTHING matched the Spatials in terms of top to bottom coherency and the illusion of floating the sound between the speakers.

If the OP considers Vandersteen "possibly too wide" (see his post above) then a lot of these recommendations are not going to work.

I have a Mac C47/ MC452 with the Aerial 7t’s and they are very nice. These speakers are a Stereophile class A  item.
