Sony xa7es, wadia 830,850,860. Opinions and tastes on these vary. To me they sound a little less involving driving direct as opposed to via a superlative tube preamp.
The Audio Aero Capitole is in a special league of it's own due to it's tube output stage and 192 upsampling. Another top dog player is the modwright XA777ES SACD player. This has a jena labs design tube output stage and volume control. Both of these players have the harmonics and midrange punch that you get with a good tube preamp. Great sounding.
