Recommendation for Integrated Amp w/ Big Sound


I've gone back and forth on a multi-channel system or a 2 channel for tv, movies, and movies. I think I'd be a nice Solid State integrated amp with a big full bodied sound will suit our living room better. 100 wpc more or less seems right from past experience.

My first thoughts, though not conclusive, are the Anthem 225, Cary CAI-1, or Harman Kardon HK990. The problem is these don't fit into my budget of 500-700 used. A used Denon 2000IV would fit into my budget but I'm wondering what is out there that has a big bold sound that I'm missing?

Lots of good suggestions, but I don't see many used I can afford.
The Wyred4sound class D amps look like an amp that I'd like, but again I don't find them used.

I'll be patient and keep looking for that great deal.
Sorry, I didn't see the price maximum. Maybe the STI 500 for 1k, but that may be wishful thinking also. I recently bought the W4S sti1000 for a second system and am floored by how great it sounds. It might be worth saving up for.
There's a Plinius 8100 for a starting price of $850. You can't go wrong with that.
