Here's some interesting stuff Anthony at Aberdeen components had to say about the DV--60, DV-50, and UX-3.
"I agree 100% with Frank. I currently have 2 of each, of the Dv-50, Dv-60 and one UX-3.
A dv-50 is very easy to uncork the performance. Dv-60 same Pioneer drive as dv50, but the dv-60 has half the size of the Dv-50 power supply, and a 1/4 of the size what the Dv-50 uses as the HQ 2 channel output.
UX3 has serious potential, ready to be unleashed, but a major bottle neck I found within the core board prevents this beast to be unleashed. (Fix is almost there)
A big plus for the UX-3 the analog board is very similar to the UX-1, another plus the UX-3 has a New (Neo) drive assembly over the UX-1, with a final plus the UX-3 can upscale the Video, via DVI, while the UX-1 cant.
Dv-60 can upscale the video threw the much wanted HDMI,
While the others lack this feature, with the exception of the PO-1 and PO-3. What get me nuts, it has the ABT top chip that can support HDDVD and Blue Ray, looking at press photos, the Dv-60 was shown sporting the 2 optional ram chips to be used with these features to top it off. Meanwhile they disabled the chip to support these formats! :c(.....My Likes of the Dv-60 internal... Cute little R-core t-former, and despite the smaller power board section, nice to see multi - Inductor/capacitor filtration being used.
Unlike the DV-50, the rest of the video section looks great. But all analog sections are nothing like the more robust section used in the Dv-50...
My wish: Give me a dv-50 with the video section of a Dv-60 (re-worked of course)
In reality: total re-worked Dv-50
Ux-3: A beast, re-worked, but I think at this price point,
I would like to see HDMI."
"The Dv-60 uses Teac's horizontal sled and vertical optical assembly. A plus over the Dv-50. Unlike the Pioneer drive, the control boards are not sandwiched under the drive assembly. They are laid out cleanly, in an uncongested manner. Again, Inductor based ground decoupling is heavily employed, showing a well designed control board. Much more Robust engineered, over the Pioneer dive assembly design. In regards to the Dv-60 power board, despite being a smaller footprint over the Dv-60, as above, inductor based filtration, is used with a well designed power board, over the Dv-50."
