Magico A3 replacement

@dpm2340 

A couple others that have crossed my mind are Avalon and Verity. Wilson is also on my radar.

Ironically, Avalons powered by Grant/Lumley tube amps and CAT SL-1 pre is one of the other best sounding systems I've spent some time with.  It's all very subjective, so YMMV, but I liked them. 😏

Your room isn’t very big, and yeah, I know Fremer has Chronosonics in his basement. But if Magico isn’t cutting it, maybe you might consider dropping your spend a little. Monitor Audio 300 Gold might surprise you. Subs optional. Kevin Deal at Upscale Audio might advise.

I was looking to buy the A3 but I felt the following speakers were better, more coherent driver integration:

• Vivid Kaya 90 (maybe Kaya 45 for your room)
• Yamaha NS5000 (they are classified as "bookshelf" speakers). I bought these and they are not going anywhere. Though I wonder if a 13 x 16 room is big enough for them. My room is bigger. The drivers on this speaker are ALL made with a new material called Zylon. Supposedly better than BE. Incredibly the 12’ woofer is made with Zylon.
• I have a Magnepan LRS+ in my office and it is a killer speaker. I planned on spending 10k on a monitor for the office. Not anymore. The LRS+ is powered by a very powerful Sanders Magtech amp, a great combo. I would look at a bigger Maggie for the 13 x 16 room.

I purchased the NS5000 new for $12k. The Kaya are pretty unique and fast sounding speakers.

BTW - I use the KEF KC62 sub with the LRS+. I also got the Magna Risers stands for the LRS+ recently and that just blew up the bass to much stronger levels. There was also a binding post tweak with the Magna Risers that may be the reason for the sonic improvements. 

You do not list a budget unless I missed it and your room is on the small side.  I recommend either the Vivid Kaya 90 or the better the Vivid Giya G3. I auditioned Wilson’s, Magico’s, Raidho’s, and Focal’s of equivalent price and chose Vivid G3s for their clarity, staging, uniformity from treble to bass, dynamics, and timbre.   Will mate well with the clarity of your Constellation amp that will have no issue driving them.  You need to warm up to their esthetic.  Read pro reviews on either model.  You have courage buying without audition.  Since this is a subjective hobby I always recommend auditioning.
