So, as much as I love my class D head (AI Clarus II) I have read enough of people saying they don't sound as good as traditional A/B etc builds that I have decided it is worth picking up a "lead sled" power amp, preferably used, possibly vintage. thought I'd ask here for suggestions. Here would be my Ideal specs (I understand I probably can't get these exactly, the closer to the specs the better): Watts/channel stereo: 125 @ 8ohms 250@ 4 500-600 @ 2 Bridged 800-1000W @ 4 or 8 ohms Under 30lbs would be awesome. Right now the QSC RMX 850 is my top pick, although it's a little heavier than I would like. All the other specs are pretty close, and I could with live with the extra weight if I needed to, especially since it has a built in HPF. The reality is this thing will probably only get used a couple times a year, on those very rare gigs when I need to play really loud and don't have PA support. Thoughts?
