Digital "Crispies" and the ART di/o


I was listening to Glenn Gould playing Bach Goldberg Variations (1981 recording - Sony Digital) the other night, through an Arcam Alpha 7 and ART di/o DAC and on track 17 I noticed this static, "crispy" noise along with the piano notes. Maybe it's the dac, I thought, so I hooked up the preamp to the analog out of the Arcam, and the crispies weren't there. Neither was the soundstage, and alot of timbral detail. My question: are the crispies digital dust in this recording that the ARCAM DAC did not reveal (I've only heard them on 2 tracks), or could they be lack of power in the ART di/o (I'm using the wall wart power supply that came with it), or maybe my new speakers (thiel 1.6) breaking in.

Thoughts?

Thanks!

I have not gotten to hear my ART yet. It returned from extensive mods a few days ago, and a good friend is playing it to break it in. For those who have not already heard the boring story, I am still under construction.

Is your ART stock or modified? How do you rate the performance overall, and what have you compared it to?

Sorry to ask questions when you are looking for answers, but I have not read many posts here about ART performance.
Al, still under construction? Damn, you need to give me a BIG heads up when you're done, cuz Joe and I'll be making a road trip your way. I'll bring the beer, you provide the tunes. Cheers!

Which input sampling rate is your DI/O set to? If it is not 44.1 then that could be the problem and if it is the external mode then you may be losing the digital lock. The DI/O doesn't have a very wide window of tolerance in the ext. (green LED) mode. Then again, there is always the possibility that something is wrong with that particular CD. Has this happened on other CDs also?
I've heard this in ART DI/O units, but haven't been able to pin it down and haven't had the chance to ask around as you are. I would notice it only on specific tracks, and it appears to be towards higher frequencies when it shows up.

My question to you, do you notice it more or less at different ART settings? (ex. X2, vs internal lock, vs external lock)

Secondly -- When you're looking at the front lights, does your lock light go on and off through a track alot? Do you find that your red light, the one I believe is actually for A/D, goes red a lot?

I know there is a DIOMODS group on Yahoo that I've yet to look into, you might want to inquire there -- plenty of folks that know the product in and out.

I think this was asked already, but is your unit modified at all?

If you do get an answer outside of these boards, please drop an email!
A 1981 digital recording is an early digital recording...that may be the problem. The DIO may be passing along more info, which may include more low level info, but it may also include flaws in the recording or engineering. It's hard to say without hearing the sound.
