I just bought a pair of 50's. My previous post concerned my preference for two speakers and straight -line amplification.
I advise using as clean and as powerful an amplifier you can.
After nearly a week-my speakers-are almost broken in.
I can sense the bass content-and I am hearing more inner detail in the mid-range.
Within 20-40 hours more listening -they should be sonically balanced-and completly broken in.
Are the 50's right for me !
My room is almost exactly a match to yours-and the sound-at this stage -is sweet, rich, deep and clear.
It's up to you what other elements you add.
But I am satisfied with my set-up.
Enjoy !
