I've been running my Nak CM1000's>V3 for just a little over a year now and love the sound. I've recently run my CM700's>V3 and like it just as much with just slight differences in sound. I think the 700's sound just a tad better in shitty venues, but the 1000's rule in good sounding venues.
I'm waiting for my CP1 leegeddy mods(Franken Naks)to come back and really looking forward to trying them. Before I had a pre, I ran CM300's with batteries into an SBM1 with nice results. The Leegeddy's, a PS and an SBM1 would make a nice little stealth rig. Real inexpensive small rig, without a pre. I wish I never sold my SBM1.
