Customers' Testimonials

The following comments have been made about the DED and the CD-CHECK products:

  • "We have been using your Digital Error Detector (DED) and the CD-CHECK disc for some time now and are very pleased with the results. Looking after 30 or so CD players and close to 50 DAT recorders in our station has just become a lot easier.

    We use the disc (CD-CHECK) to evaluate the CD players before they fail in an on air situation, or whenever an operator reports questionable operation. The DED has improved the reliability of the DAT machines, allowing us to check out the decks after repairs, and routinely before they fail. Keep up the good work..." Ralph Keeping, Maintenance Coordinator, CBC Radio, Canada

  • "....some of my CDs are scratched to hell and are unplayable, so DJing the rave with CDs I wasn't sure about would have been a bad idea. I checked my whole playlist (watching and waiting for the red LED...) and replaced songs that showed errors with ones that would play error-free. father's Marantz has come back from the plant or repair shop with new parts installed. It doesn't do any better with CD-CHECK than it did before, but with any CD in good condition the player plays flawlessly. Sounds real nice, too. The DED sits on top and occasionally we see it light up red, but only with my CDs, not dad's finger-print-free CDs.

    ..the frequency of clicks tends to be once or twice every rotation of the CD. Usually there are a number of visible scratches on the surface of the CD, although only some scratches are deep enough to cause DED to light up. Sometimes the DED is displaying error messages (intermittent flashes of the red LED) while the music plays uninterrupted from the Marantz. I suppose our player is built to deal with small scratches easily." Matthew Claener, DJ, Canada

  • "I guess the folks at Digital Recordings weren't content to have the best error correction and error concealment test CD on the market. Shrtly after developing CD-CHECK, they developed and are now selling a unique device called the "Digital Error Detector" or "DED" for short.

    Both CD-CHECK and DED were both very informative and fun to use.

    Digital Recordings' CD-CHECK proved to be an outstanding tool for checking the quality and serviceability of CD players. It has found a welcome home in my bag of tools when evaluating players. Highly recommended ! DED is a unique and useful product as well. The nices thing is that it can be used with any audio CD, be it music or a specially constructed test disc.

    Another plus is that DED can detect errors with DAT players as well. I therefore give an enthusiastic "two thumbs up" to DED as well. It's a super product...." Robert Thompson, "How to Evaluate CD Players - and How NOT to Enhance Their Performance", "$ensible Sound" magazine review, No.72, Nov / Dec 98, p.10-18, USA

  • "I had a chance to check out the CD-CHECK today and loved it. I tested 5 different units and got varied results that were a bit surprising.The school (Conservatory of Recording Arts) where I"m on staff wants to buy one already. So it's a hit.....I've used it and I highly recommend the product." Kevin Becka, musician, sound engineer, teacher & reviewer, USA

  • "Your new CD-CHECK evaluation disc has already proven itself to be a wonderful, quick and reliable resource for our store in evaluating trade in's and new products that we receive often from our suppliers for evaluation. We highly recommend your CD-CHECK for any audio store, manufacturer or importer." Steven Budovitch, Glubes Sound Studio, Canada

  • "Not since the introduction of the Dennison Protractor have I found an audio set up tool as impressive and useful as the CD-CHECK. What the Dennison did for turntables the CD-CHECK disc will do for CD players. I've been in the Hi End Audio industry for 25 years and I am regularly called on by customers to tune up their systems. The CD-CHECK will now permanently be added to the battery of tools I use to do this job. Congratulations to the folks at Digital Recordings for a truly spectacular product. I won't leave home without it." Gary Harrington, audio consultant, HARRINGTON AUDIO, Canada

  • "I've always thought that error-correction abilities were underemphasized in high-end CD-player reviews. As I see it, if the digital data isn't read correctly in the first place, no amount of D/A magic will make it sound right...I'd really like to believe that this superior error-detection scheme will catch on...I've become quite fond of CD-CHECK. The test is so simple and quick that I can get good results in a matter of seconds....CD-CHECK offers an unparalleled CD-player evaluation tool. Nothing else I know of works quite as well for really ferreting out which players correct errors well and which don't." Greg Smith, reviewer, "SoundStage!", the high-end audio magazine, USA
