Best Sounding used amplifier under 1000???


Looking to get into a used 2 or 3 channel power amplifier to power my Paradigm Studio Reference 80 ver. 1 speakers. Looking at around 200-250 watts per channel or such. I am currently using a Xtant 3300c (60x2, 360x1) high end car amplifier and it sounds so wonderfull but looking to get into more power and with possibly better overall sound (how much more better will it be I dont know?). I'm using Monster Cable M Series CX-4 Bi-wire cable for the speakers. My limit is $1000 used for the amplifier. Please post any comments and suggestions retaining to this idea.

Thanks!

HA!!! to the other choices (kidding guys!!) If you can find this gem, an EAD Powermaster 500 is incredible. Should be able to find one easily for under a grand and its design helps it excel in stereo listening as much as it does in HT applications. Don't let the fairly modest 100X5 wpc fool you. this thing can output better than 300wpc in stereo listening with the smooth, high-end sound EAD is known for. Quite a few people have stated they feel this is possibly the best amp for stereo listening that EAD makes......that may be a stretch but there has to be a reason someone said it:) good luck!!
The EAD is great. I own the EAD Ultradisk 2000 Reference CD player and it just killed Musical Fidelity A3 CD, Bel Canto DAC 1 and a few others. EAD has great products and they look awesome with the Jeff Rowland faceplate. If you can find one, let me know because I want one too!
What is the difference between the 12ax7 and the mullard CV4004 tubes???

I have a mint condition Browning Mark 4A CB radio from the 70's that uses 12ax7's and was wondering if Mullard CV4004's would be a replacement or any better????

And maybe I'll get the Rogue 88... but I'm still looking around!

Thanks for the comments and keep them coming!!!
I've heard all of these and can say without a doubt the McCormack DNA 0.5 deluxe can be had for that $$$ used and you will never look back.
The Mullard CV4004 is a Military grade version of the 12AX7. It sounds better than stock tubes but costs about 5X as much.... They go for about $50 each.
