Dtc:
I got my DA-3000 today. It has a large number of op amps, either 5532s or 2114s (JRCs version of the 5532). No matter. Sound quality is mediocre at best.
I did a test recording of Blind Faith "Had to cry today" because I have the UK vinyl LP and three different versions on CD (US Polydor 1986, German RSO 1986, and 2001 "deluxe edition"). The vinyl sounds better than any of the CD versions, so a faithful recording of the LP has a leg up. I recorded a 24 bit, 96K copy of the song direct from the outputs of the Spectral DMC-10 (what I listen to, not the tape monitor) and converted the .wav file to FLAC with dB Poweramp. I then A/B'd with all the CD versions and the LP playing directly.
The copy recording made with the 3000 could not hold a candle to the LP. Period. Not even close. It was not even as good as most of the CD versions (although these are all different sounding from the LP). Symbols, in particular, were "mushed" and distorted compared to the vinyl.
Actually quite disappointed. Swapping opamps is not really practical due to the large number. And what is worse, it appears all these amps are cap coupled with electrolytic caps. Without a schematic, modding is not even possible.
For making copies of rare, vinyl not released on CD, or maybe versions were the CD is unlistenable, maybe the DA-3000 will work. But don't expect that vinyl air and magic to come through in the recording.
And I also found out the DA-3000 will NOT record to USB drives, only CF or SD cards. It will not even function with USB HDs. It will only play back from a USB drive. So you have to record your files to an SD card and then convert it or transfer it to a USB drive on another computer. You can transfer files on the DA-3000 directly, but it very complex and slow. Better done on an outboard PC.
Looks like I'll be looking for an Ayre.
