It pains me to do this, but I am selling my modified Onix XCD-88 to fund the purchase of a more expensive CDP. For those who don’t know, this is the same unit as the highly-regarded Music Hall CD25. Purchased new from Underwood HiFi/Parts Connexion as a Level 1 modification for $850. Current price to upgrade a stock unit to Level 1 is $380.
I upgraded to Level 1+ by adding Burr Brown OPA-627 op-amps for an additional $100. These were subsequently upgraded to the newer Burr Brown OPA-827 op-amps. The stock 2604s are also included.
Unit is in excellent condition and has performed flawlessly. I have the original box, manual, and remote. I will post some pictures shortly.
Here is description of the modifications performed by Parts Connexion:
BlackGate output coupling capacitors
4 x MultiCap 1% polystyrene film and foil capacitors are added in the analog filter stage
