Jitter reduction, best device?

Read up on Benchmark DAC1 also. They pretty much stake their product on its low jitter output even in the face of any extremely jittery input. No reviews with proper measurements have found fault with it, so far, although listeners may like or dislike it, according to taste - same for any product.

Mapman,

It sounds like you may be hearing beat frequencies. This is a subtle effect that could come from a number of things - including your room setup and/or listening position. It is, as you say, nearly impossible to be conclusive that any specific audible effect is from jitter. Jitter is a detail that does not necessarily stick out like a sore thumb. The industry continues to argue about the thresholds of its audibilty....

so I suspect it was some artifact resulting from the Denon's DAC.

It can often be subtle but everyone agrees that DAC's do sound different. Whether this is the effect of jitter reduction or simply the result of a different output stage (tubed) or both is nearly impossible to say.

Hens,

the bottom line is that with a DAC which doesn't reclock or reduce jitter (AN 1.1X Sig.) this jitter reduction device made a significant difference.

Interesting. Your observations suggest that for those connecting gear through digital interfaces it is worth investigating this issue when selecting a DAC. For those with a DAC already (particularly an older generation DAC that rarely had anything other than a simple PLL), this points the way towards a postential improvement.
