Well, on the cheap you could do worse than the Raysonic 128 as a 2d unit. It really responds well to tube changes and turns in a very credible performance. I retired my old Cal Alpha/Delta without a tear.
I'm not as as fond of the use of an equalizer in this function. IMHO, you can shelve down the frequencies where the 'digital glare' occurs on 'bad' CD's but you don't change the fundamental glare - at least I can still hear it anyway. But using the right tube CDP (or an outboard buffer as suggested by Beheme) you can by selecting the right tubes soften the glare itself.
FWIW.
