Esoteric UX-1 and X-01 are not the same players and they are not, IMO sounding the same. X-01 is better than UX-01 in RBCDP. Also, all Esoteric gear that I auditioned in my system( I own DV50s and tried D-70vu/P-70vu and D-01/P-01/G-0s combos) sounded very best via balanced(XLRs) connection. Reimyo CDP-777 is very good indeed but, IMO it is sounding best via single-ended connection. More or less X-01 and CDP-777 are in the same class-I agree with Teajay.
One other thing-Esoteric is using PIN2 positive on thier balanced connection and Reimyo is using PIN3 positive on XLRs. I personally heard Reimyo out of phase and his owner was raving about the sound... When I pointed out that we are listening in inverted phase he didn't belive it. After correcting the phase we listen again and he didn't like the sound of his player any more!! So, there are many issues about good sound...but, personal preferences are allways first,IMO.
