Need Advice on a Low End CD Player Giant Killer


I'm on the lower end of audiophiledom - I have Paradigm speakers, an Outlaw receiver and a Sony multi-disc CD changer that had the first modification from Tube Research Labs.

My original intent was to send it back to TRL for them to do their latest modifications on it and tighten it up a bit since discs skip a lot or don't read well, but in doing my research online it seems there's a lot of controversy about TRL.

Basically I want to spend $500-$700 tops for a new or used CD player that's a giant killer. I'd love to have a modified multi-disc player if those exist that equal the sound quality of a single disc player, but I'm open. I need suggestions, and if anyone can give me any info on the work and honesty of TRL I'd appreciate it as well - I haven't updated my set-up in a LONG time but am ready to make a change.

Habit. I've got around 600 redbooks. I'm continuing to buy them because they are so cheap right now. Kind of like how vinyl was 25 years ago. If I was just starting out, the server would probably be the direction I'd go though. 
A single disc player will outperform a multi. I would purchase a used DAC with a new transport.
I just looked up the Oppo 103.  Those above recommending it, are you using this Blu Ray DVD player for audio?  Just curious.

I have an older Oppo DV970 and for $100, I don't think you can beat it.  But it's getting older and I'll need to replace it at some point.
