Chord's Choral Blu offers a surprisingly large number of output options for a CD transport. To examine what it did, I connected its data output to the digital input of the RME soundcard fitted to my PC and looked at the data in the digital domain using Adobe Audition and RME's DIGICheck program. Fig.1 shows the statistics of the Blu's output data while it was set to upsample those data to 88.2kHz and increase the word length to 24 bits. The test signal was 16-bit "digital black" on a test CD. DIGICheck indicates that bits 1–16 are indeed permanent zero, shown by…
So it's reassuring to now and then review a product whose mechanism…

First, a few basics: Audio Valve was founded by Helmut Becker, a German guitarist and music enthusiast who began building amplifiers 40 years ago, at age 15, and who has spent the greater portion of his professional life building audio electronics and medical equipment. Herr Becker and his wife, Heike, operate Audio Valve in Kalletal, a municipality in the Lippe…
