Best redbook CD player


I wish to buy a CDP to play CD's, not DVD's or SACD's. My budget is under $2500 in the USED market. Any suggestions?

Thanks all. I current have a Meridian 507 24 bit CDP. Would anyone not conceed that the Resolution Audio Opus 21 would blow it away? I am thinking of using the Meridian for a second system, and maybe trying the RA in my main rig. I am 75-90% vinyl but still love certain CDs a lot, especially when the CD bests the LP (Glenn Gould on Sony for example).

I almost got the Lector CDP MK3. Anyone have any thoughts on that versus the RA? It is certainly more expensive. I have learned not to trust price tags in this regard!

Without question the BAT VK-D5 24bit CDP...it is the turntable for the digital age. Then again, the vinyl aesthetic is not for everyone. Some prefer a little auditory pain with their playback machines.
I am happy with my very reliable well built Audio Research CD 3 MK II and comfortable that if if ever needs service ARC will repair it quickly at a reasonable cost. I have not experienced this quality service and support with some of the other high end brands out there.
there is a lot to be said for Weiserb's comment - especially considering that a modified unit will have no warranty from the original manufacturer. ARC still fixes stuff from thirty years ago...
