The old Optimus CD-3400 used to stir up controversey over it being as a good sounding transport compared to the likes of Levinson. Stereophile had mentioned it quite a few times, even seperate power supplies were sold for them. I also like the older Sony D-555 more so without a DAC than the CD-3400. The CD-3400 has a mini jack to RCA, and the D-555 has a toslink digital output. I would look for a model with a digital output if possible.
