I'll restate what I said earlier.
Try to find a used McCormack DNA 0.5 or DNA1 for under $800. They come up for sale very often, and they are outstanding amps! Power, finesse and some warmth.
From what I can tell, you've said nothing about using this setup for home theater. If this will be used in a two channel system only, the best thing you can do is to dump the Denon. Any Denon! You can get a $10,000 amp and it won't sound good with the Denon ahead of it in the chain.
You've given a budget of $1000 to $1300 for a preamp and amp. For $400-$650 you can get an Audible Illusions L1 or 2D preamp, an Audio Research LS1 or LS7 preamp for $500-650. The McCormack DNA 0.5 or DNA1 solid state amps are in the $650-800 range.
Keep the Signal cables and don't worry about spending on anything more expensive. Going to biwire speaker cables at this time wasn't necessary, but since you have them. stand pat with them.
For now, keep it simple and affordable. Good luck!
