Agree with Reb1208.
I brought a DV-50 with the intention that it will be only used for SACD, DVD-A and DVD-V. For the red book CD, I had a Wadia 270 + 27ix system.
In the first week of usage, the DV-50 is just so so. However, after a week of intense running-in, the sound improved tremendously. Then I started to take the DV-50 serious.
I enabled the CD-direction option, turned off the video circuit and display, added a grounding wire to the pre-amp, put the DV-50 on a proper auido platform. Then the sound improved to another level.
SCAD play back from the DV-50 was already better than the Wadia playing the CD layer. The CD play back of DV-50 was still behind that of the Wadia. Basically, the DV-50 CD play back is too bright and the low frequency lack enough control and was misty. At that point, I also noticed that I have to use a rather low volume setting in my pre-amp for the DV-50. It seemed to suggested that the voltage of the output of DV-50 is too high.
I immediately changed to use the RCA instead of the XLR output of my DV-50. Bingo! It solved most of the problems. After a few more days of running in, the CD play back from DV-50 is still behind that of the Wadia, but by not much.
I was surprised, excited and considered that it might not be worthwire for keeping the wadia combo. So I sold the Wadia combo together with my ML 380S pre-amp and brought a ML 32 pre-amp. I can tell u that the preformance of DV-50 + ML32 is way better than that of 270+27ix+380s.
