Sonic Frontiers Ultra Jitterbug Processor

If you can find a Camelot Dragon 5.1 it is a higher end anti-jitter processor that sells for a great price!

Plus this is one of the only ones that passes DTS,AC3 etc... perfect for hometheater DVD players also has two inputs

It's was outclassed by the original A.A. DTI Pro years ago, but it's still supported by Assemblage while the Pro/Pro 32 have no support. The Camelot should be better.

You might also consider a used Genesis Digital Lens. This device was more sophisticated than the others mention above. They use phase locked loops to dejitter the incoming signal.

The Lens actually decomposed the incoming SPDIF data stream, discarded all subcode information (a useful jitter reduction technique by itself), buffered the audio data in local memory, and then clocked the data out the memory with a high precision local clock. The Lens then reassembled the data into a new SPDIF signal minus the subcode and output it to the DAC.

It also applied dither to the audio data to extend it to a user selectable 18 or 20 bits.

Don't waste your money, even on a low quality CD/Dac combo the improvements are noting to write home about and forget using it on a higher end CD/Dac combo. Iv'e tried on both and with the lower end combo it seem to give the higher freq. a cleaner sound but took a something away from the bottom end making for a non musical sound. For the higher end CD/Dac combo it was a disaster. I have tried the Sonic Frontiers and the Monarchy, both of which I sold weeks later. This is just the results with my system, however there are many that use and like them as mentioned above. I'm not trying to knock these units as they have sold many but I don't think they are the answer. A bit off topic but if your looking to do some upgrades that won't break the bank you may want to consider a few dedicated lines or look into room treatments as these two things will get you real improvements.

Go for the Digital Lens or the Assemblage D2D-1 Upsampler jitter reducer.
