Are you talking about the low freq "notch" filter that up and over sampling DACs use? I am getting away from digital but this is interesting. SK recently got a 47 Labs DAC that has "no sampling?" Anyway, XRCD is way too expensive! I'd rather get an LP
There are currently four companies that I know of offering digital components that sport zero upsampling/oversampling and no digital filtering. I believe that Audio Note was the company that started this trend, and it is the only one offering integrated tube CD players with these features. The other three companies are 47 Labs, Wavelength Audio, and Zanden.
While I'm almost certain that all of these filterless digital products would measure quite poorly in comparison to "traditional" CD players, they truly sound superior to my ears.
David Cope, a fellow Audio Note dealer (his very cool shop is called Triode & Co.) and a member here at AudioKarma, actually purchased one of Sony's top-of-the-line SACD players so that customers can compare its performance with SACDs to the performance of the less-expensive Audio Note CD2.1x with Redbook CDs. Now that's putting your money where your mouth is - and guess which unit consistently comes up the winner?
Of course, vinyl still remains my favorite source, but here's an interesting story:
Just before the Lima show, I had a customer over who wanted to hear the Audio Note OTO SE integrated amplifier and Audio Note AN-J/LX speakers that I had just acquired. Knowing that he was a vinyl buff, I decided to pull a little stunt - I took out my RCA Living Stereo LP of Debussy's Iberia (Fritz Reiner/Chicago Symphony Orchestra) and started spinning it on one of my Kuzma rigs, but the OTO SE was not set to "phono". Instead, I discreetly hit the "play" button on my Audio Note CD2.1x, which contained the JVC XRCD version of this title. And guess what? My guest immediately relaxed in the listening chair and began singing the praises of analog playback! I only played this game for a couple of minutes, but the results were quite telling, in my opinion.
P.S. In case you're wondering, the customer was quite taken aback when informed that he was listening to a digital source, but reluctantly admitted to being rather impressed. Still, I don't think he'll be adding a CD player to his system anytime soon - he's quite set in his ways!
P.P.S. I don't normally engage in such shenanigans with my customers, but I know this fellow pretty well, and I simply couldn't resist...
