CD Player to match with ARC and B&W 802 Martix

An excellent match and excellent player would be the ARC CD-2, available used at very good prices lately. You'd probably be very happy with it.

There is a Theta miles cd player that was posted for sale today for 1,100 great deal for a great cd player it has an anologe volume control so you can run directly to you amp and bypass a preamp. But my first choice would be a MARK LEVINSON 39 Mind blowing detail. You can pick one of those up for around 3,000 good luck

Electrocompaniet 24/192 CD player. The best I've heard regardless of price. Not cheap, but can be had for around $3200.

YBA makes digital closer to analog than most players in it's class

My system is sort of like yours: ARC VT-100, LS-16, B&W Matrix 802's III.
I've tried Wadia 830, Levinson No.39 and Meridian 508.24.
The Meridian is my preference for overall musicality and soundstage.
