This is an original (not the most recent) version of the Paradisea dac. I swapped the opamp to the LM4562, added power supply filtering to the opamp as suggested in
this post, and upgraded the output caps to Auricaps (3.0uF). The opamp upgrade is what's used in the current Paradiseas. The two upgrades improved the sound considerably, IMHO.
Also included are a WE396A (D getter) with ~150 hours, National 2C51, Raytheon 5670, and the stock GE 5670.
Asking $450.00 OBO.
