Looking for a DAC for the Squeezebox Touch

"Wonder if it's worth to get the Metrum Octave to connect directly to a SB3 through optical link without reclocker?"

K330,

I contacted Metrum with the same question

"While I am waiting for my Octave to arrive I have one question. Some have said that the Octave is very jitter sensitive and that a good quality reclocker between the Squeezebox Touch and the Octave will improve sound quality. Is that possible or even probable? There is so much of what I call 'Voodoo' in the audio industry and amongst audiophiles that is hard to know what to believe. I don't like wasting my money on imaginary benefits ;))

To which they replayed

"Yes there is a lot of Voodoo so be careful. As you know there was a very good reviews from 6moons and the Hificritic where the dac was compared with very expensive units (+ 10000 Euro’s) and it was very close. The Octave has a very low jitter ( below 40 pSec) so there is no need for some extra gear to reduce this. Difference in sound by this gear is mostly created by upsampling and people do not realize that this up sampling methods create ringing in the signal. This is what you hear , pre and post ringing. There is no need for such devices as you cannot create info which is not actually there so please forget such gizmo’s . Only real hig res. material improves the sound."

Bottom like for me is that I am very very skeptical about many (most) of the so called audiophile 'upgrades'. When the manufacture of the product calls upstream jitter reducers (in so many words) a waist of money, I trust them a 1000 times more then any supposed audiophile claims.

The manufacturer (Metrum) states that no matter what source is being feed to it, it reduces the jitter to <40ps. (otherwise the 40ps claim is pointless and they would not consider a jitter reducer a waist of money). I would think they know their own DAC better then anybody and would know what would make it sound better.

Since each word of data arrives every 1/44,100 seconds or 22676ps (for redbook material), 40ps is a 0.176% possible variance, which is extremely low. Even if you feed it with a lower jitter source it would likely not improve the actual jitter of the DAC.

IMHO, you can Google "The ten biggest lies in audio" and add reclockers to the list, at least for the Octave.

I got the Audio DG Digital Interface just for kicks and it made absolutely no difference to the sound over the Octave itself, at least to my ears. The manufacturer was correct, don't waist your money. My Digital Interface is going on the ebay. Bye Bye...
