Jitter reduction, best device?

There's a very old (1996) article from Hi-Fi News on the Monarchy website where four "jitter-busters" were tested and measured. The Monarchy was apparently the only one that successfully reduced jitter. I'm sure that in 2009, the jitter reduction devices would be measuring far better.

Personally, I've just ordered the Monarchy DIP Classic to put between the Wadia 170i and an Audio Note 1.1x Signature DAC (which does no internal de-jittering).

I plan on posting a review of the system in the next month or so.

This may have been addressed in other threads, but how does one know for sure that jitter is the issue when not satisfied with the digital sound?

I use a Meridian 518 and besides jitter, I rely on its gain function which overcomes the low recording level of many discs issued in the 80s. I would also recommend the EAD 7000 Mk I-III. Still serviceable, and handles jitter and sound is warm. I use an EAD Theatermaster 8000 that incorporates the jitter technology of the above dac. Reasonably priced used. Another possibility is the Apogee Big Ben which is a reclocking device that is not often seen on Audiogon because of its professional use, but many on Ebay and supposedly does a bang up job as to lowering jitter

Mig007, I also have a EAD DSP-7000 Mk II with the balanced output option that I picked up on the 'Gon. Sounds great with my Haflers and my GFP-750 in passive mode. Have you ever experimented with the 4x/8x oversampling switch? I've never opened mine.

By the way, to the original poster Boleary3 - I just want to be clear that I am not claiming the 518 to be the best device to reduce jitter. I am quite certain that Audioengr may be able to supply you with a more qualified answer. I found the 518 to be a budget alternative in taming the jitter as a result of the path I took with my PC audio endeavor. I was ultimately pleased with its performance and versatility. I just couldn't see investing big bucks for marginally better performance for an audio "transport option" that is still being developed.

I have fiddled with that switch on an EAD Theatermaster Classic and noticed little difference if any. Really did not experiment. I've since switched the processor out with an EAD Theatermaster 8000. The 518 may not be the best anti-jitter device, but it certainly is the best bargain for taming digitalis.
