What speaker is the most musical, one you never want to sell?

I've owned Martin-Logan CLS-1s for over about 35 years.  One of the most transparent ever.  Hard to move away from Will probably add a  ML sub this year.  At retirement, will seek out a set of Sonus Faber Amatis, but will keep the Martin Logans.

B&W 800 matrix, Lovely classic sound

After some years using these for Totem Model 1 as my favorite speakers, I must say that the recently acquired Closer Acoustics Full OGYs are here to stay forever!

They deliver everything I ever dreamed of in my 17sq meter room: a full range, tridimensional, transparent, effortless and uber engaging sound! I am done :)

I have five different speakers in my collection, but only the Magnepan LRS+ will stay, mostly because they are easy to store when using the Full OGYs.

Salk Veracity H2-TL. But my Snell Type D are a very, very close second.

7rps7 - I have to agree. I gave up my Moabs for a pair of $10k Martin Logan's, and now wish I had the Moab's back. They were so much better. So much so that the ML's are now up for sale and I've talked with Eric about getting a replacement pair.
