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

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. 

My favorite bits from each of the speakers I’ve been attracted to. I am leaning towards Magico and Kef for advancing the science in every aspect they can consider 

Although not in the same league as most loudspeakers here I am blown away by the sound quality of the Elipson Prestige Facet  24F's along with a pair of subs. The tweeters in particular I find very pleasing and non-fatiguing . They were reasonably priced as well.

This French company has a following over in Europe but are not well know on this side of the pond. Next upgrade will be to the amplifier, currently eyeing the Sugden A21se.

I'm very happy with my Von Schweikert Model One speakers.  Paired with two REL S/510 subwoofers. 

With retirement on the horizon, I'm not likely to be putting out the cash to try to improve upon them.  

I still have my Von Schweikert VR-4 speakers sitting under covers.  I think one of my boys will end with them.
