Everyone knows the Tech21 unit - thing sounds absolutely amazing in a pre/power setup. I'm regretfully switching over to a Shuttle (I know, they're amazing, but I like my pre/power setup, but small apartment = small gear). Looking for 225 shipped OBO on this.
Behringer Europower EP2500

Puts out 500 watts at 8 ohms. I'm not going to lie, it's a heavy beast. The thing weighs a ton. But it goes down to 2 ohms, if that's yer thing, and it's durable as all hell. It's been in a rack case so it has typical rack scuff, but not much else. I'd like to get 200 for it but again, will consider best offer.
I'd do 400 shipped for both without hesitation, and I'd throw in a rack case fo' free in that instance. PM with any questions, and thanks!
