Odyssey used to make a dual-mono version of their monos. It's currently only on their Mexico site. Not sure of the pricepoint and level of performance you're looking for but I found theirs to be an excellent amp overall. My friend had one that I had in my system for several months. I'd highly recommend it. There's one for sale currently on A'gon. No association with the seller. Recommendation is general, not knowing the rest of the system you'd be pairing it off with. It has plenty of power at 180w into 8 ohms, and is very fast. A tad on the warm side, which I liked. Best after warmed up, better yet if left on 24/7. Nice amp for not a lot of money. I think the owner of that company, Klaus Bungee, also has a great upgrade program and transferable warranty.
