Greg - You've certainly attracted a lot of good advice. Ha...maybe too much advice. For my two-cents worth, I owned the top of the line Prima Luna and did lots of tube rolling and such. Loved it for two years. But last year I heard and purchased a Line Magnetic 845ia and the "wow factor," as you put it earlier, took a huge leap up/forward - improved presence, body, speed, sound stage, more natural instrument tone, the whole schmear...and all non-fatiguing. My speakers are Forte IVs. As an aside, two weeks ago I added a Border Patrol DAC and my entire system improved yet again. Crazy, and I thought I had reached the promised land.
