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

My second system's speaker is the excellent Studio Electric M4.  I have had them about a year and still love them.  Definitely a speaker I will hang on to for a long time.

I was looking at the MoFi Electronics, Sourcepoint 888. Never heard them, so I wrote the company and asked if they'd have a pair at AXPONA this year. They said yes....but they won't be demoed???? 
Guess I'll have to do some sweet talking to see if I can get them to cooperate. 
My concern with those is I heard the V10 last year and OMG, the bass in a large room was beyond excessive. Hoping the 888 is more balanced. 

traudio, I have never heard a V10. I do have a single 8, for my center channel. It blends very well with the 888's. I have not noticed excessive bass. I know every room sounds different. I'm in a 1300 sq ft room, and have (3) subs to balance out the system. But, in 2ch mode I can run the 888's alone, and with the subs, calibrated with a miniDSP and REW software. Most music doesn't need subs. I don't like boomy bass. These are good, tight sounding bass speakers, at least in my room.

A beautifully restored/customized set of Altec Valencia. After the Sonus Faber, Thiel, Equation, Audio Note etc go-round (still have the ANs) these suit me in every way and bring me pure audio joy!

My Reference 3A deCapos. The only speaker I had once, sold, and then realized I had to get again years later. And now that I have them, I cannot possibly see letting them go.
