My jbl-integration failed after the stupid PAC converter gave up and so I figured I'd go here. 4 matched jbl components front and rear, alpine HU, and this amp. No subs.
Amp seems medical grade. It's better built than the jbl speakers are (speaker assembly was a bit of a disappointment but still sound good) and it's clean. It pushes the 6.5's effortlessly, is clean, doesn't seem to color the sound, and controls cone movements accurately. The s/n ratio was a little low compared to some of the others but if there is noise I can't hear it. It is a little large to shoehorn into some spaces but class AB would be. Very happy.
UPDATE: found a flaw: I kept noticing that I one speaker (left front) was always louder than the rest. I ended up sending a test tone through the amp and 200hz and measuring each output with an ac voltmeter. The left front channel on my amp is always higher by 5-10% unless I keep the sensitivity adjustment down all the way towards 4v. It's a bit of a pain because it's noticeable and there's no per-channel adjustment. The rear channel is balanced left to right.
