If is is not an MKIII then it does not have the Digital flywheel.That was added only to the MKIII versions of all their dacs.

Thanks for the info! Any thoughts of where I might find a pdf or manual? I've used an original Theatermaster in the past, and remembered, incorrectly that the dacs in it were "the same as the 7000". Been out of two channel for a while and when I restarted a couple of weeks ago, the front end was and is a Sony 200 disc changer. The 7000 throught the toslink out makes it sound considerably better. Believe it or not, the system is Belle Klipsch, 2a3 monos, and a PAC ref ll pre (and a soon to be setup, VPI mklv) so its pretty revealing. Still the bad rap EAD is enjoyable. I get a lot of error readings on a few cds. Can't hear 'em. My real lust is for the EAD 9000 when one surfaces cheap.
If you email me privately and I will send you a photocopy of either the original DSP 7000 or DSP 7000 M3 manual (I have both). Here is how you can tell what series your 7000 is:
Series 1 - original 20 bit dac, it also has a de-emphasis indicator light
Series II - Burr Brown PCM63 Series K dac
Series III - Pacific Microsonics PND100 HDCD chip, Digital Flywheel. De-emphasis indicator light replaced by HDCD indicator
I also agree with the above post, DSP 7000 Series 3's are excellent candidates for modifications and make an already good dac sound awesome.
"BRF Is there any external indication between the 7000 and 7000 m2?"
No, the Mk1 and Mk2 look identical with no external differences. EAD did not silk screen Series II on the faceplate as they did with late production Series III. Many of the original Series 1 were sold with the gold faceplate. Upgraded Series 2 to 3, and early production series 3, have a HDCD badge placed over the de-emphasis indicator light (which now denotes HDCD disc). Late production series 3 had HDCD silk screened and series III on the faceplate.
bad rap? What actually happened was the absolute sound gave the 7000 a excellent review and purchase recommendation then stereophile for some reason gave it a bad review I believe it was just to create controversy which obviously does sell magazines. Anyway stereophile was absolutely flooded with letters from ead owners who were very much in disagreement with their review. The ead 7000 is a very musical sounding digital converter. The absolute sound review was correct stereophile review was not period.
