Transport for DAC

The Paradisea tube DAC supposedly reduces jitter as long as the jitter at the source does not exceed a certain tolerance as I understand it.

Not sure exactly how this works. Maybe someone can explain?

It is not the same thing as upsampling and reclocking as like the Benchmark though I am pretty certain.

Still, I have to say though that I cannot hear any clear defects or differences in the sound reproduction using either Roku Soundbridge or the Denon player's transport that I might attribute to jitter.

Al - are you running XLR or RCA?

RCA at present, because that is what my Rotel cdp puts out, but my Classe CP-60 preamp can accept either.

Digital newbie here. I have been listening to CD's since they came out.I have found that they are no where near as musical as LPs.Then I got my first DAC. I just got a Audio Alchemy 1.1 DDE and a AA DTL 1.0. This has transported my CD's into another world altogether. Listening is fun again. Now to add to the string: I am using a cheap Sony NS601HP.This has a TOSlink digital out interface to connect to the jitter box/DAC.(It also upgrades std. DVDs to 1080P,which is nice).
It cost about $60.00 at Costco. This setup rocks! My Accoustat 2s now have wide and deep,transparent soundstage with a much sweeter bass and treble than I have ever owned.
Makes me wonder if I really do need that VPI I am bidding on.............

sure I do.

Al - One review of the Benchamark claims way better performance at 0dB settings for XLR (four jumpers inside) than any other position (-10, -20, -30). I can hear a little livelier sound at 0dB than -20dB but -10dB is much worse and my 0.5m cable has total of only 6pF/ft x 1.5ft=9pF.

Benchmark stated in manual that for XLR:

Setting (dB), Output impedance (ohm)
0 60
10 1600
20 500
30 160

and -10dB is really bad. If you're concern with it - get DAC1 USB. I think that pre has also LM4562 on the output and different divider but verify. I'm not sure how better it is - will check their website for the manual.

Word of a warning - Benchmark is not a warm sounding DAC. According to John Siau it was meant to be neutral because warm sound (exaggerated even harmonics) sounds wonderful with voice or guitar but not with instruments that have more complex harmonic structure than simple overtones (like piano or percussion instruments)

Interesting comment. FWIW I noticed an improvement in percussion and piano with the DAC1 versus standard low end Sony CDP. Vocals also sounded thinner and more articulate with the DAC1.

I prefered the more natural sound of the DAC1 (more natural to my ears - especially for cymbals and piano) but a friend of mine (given an hour of blind A/B testing) prefered the regular CDP sound with thicker vocals but less realistic cymbals. Of course, he thought the organic thicker sound without the DAC1 was more realistic for vocals.

I was able to accept hearing exaggerated vocal articulation due to the singer using a microphone in the recording process and get past this reality and still enjoy the music whilst my friend found it intrusive (too evident that we were listening to a recording).

Certainly - it is a very subjective subject! And what I describe above was extremely subtle and NOT evident on every recording... on some recordings we were unable to tell which was the source. It suggests that you need to listen to a wide variety of music and recordings in order to make a full comparison and it inevitably requires some compromise. To me the greater the precision the more problems/anomalies you discover in your recording collection.
