The following comments have been made about the
"Digital Recordings' CD-CHECK is an outstanding tool for checking the quality
and serviceability of CD-Players. Although its specially encoded test signals
are extremely sophisticated, it requires no special training and/or equipment
other than a good set of ears with which to operate. Highly recommended ! "
Robert Thompson, reviewer, "The $ensible Sound" Magazine,
"Wow CD-CHECK is exactly what I have been waiting for ! Fantastic ! So easy
and fast, it's great"
Jeff Liem, Atlantic Photo Supply Ltd., 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
"I tried the CD-CHECK and found your system to be very simple to use and
interpret. Consequently, I would not hesitate to recommend your system to
anybody who is looking for a quick and easy method of testing and/or
evaluating a compact disc player"
Tom Hayman, P.Eng., acoustician, Canada
"Overall, I found this product to be remarkably easy and fast to use."

"The CD-CHECK has shown itself to be an invaluable tool for problem analysis

"CD-CHECK is well worth twice as much as other similar products while costing
half as much. Marvelous !"
Mike Merrigan, Peak Audio, Canada
"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
"CD-CHECK is one of the most innovative products that I have seen in 20 years
in the computer hardware field. It is an essential addition to every CD
owner's tool kit."
Reg Hody, K-PC Ltee, Canada
"CD-CHECK mercilessly exposes the differences between CD players. One of our
CD players seems to work OK with most (but not all) CDs. It tested very low on
CD-CHECK. I wish all my digital equipment could be checked as easily and
precisely as my CD players can be with CD-CHECK. At PUT IT ON CD one of our
problems is how to guarantee our CDs will play on all CD players. With
CD-CHECK we could provide a guarantee that our CDs will play properly on any
CD player that meets minimum standards"
Reg Macmichael, Put It On CD Manufacturing, Canada
"I am working in the area of AI-based processing of audio data. Consequently,
I cannot rely on subjective evaluation of CD and CD-ROM fidelity. Your
valuable tool (CD-CHECK) helps me to accurately determine the reliability of
my data sources. I noticed that similar CD-ROM players can have much different
capabilities in the domain of error correction. It would be almost impossible
to determine it without the tool you have prepared."
Prof. Andrzej Czyzewski, Sound Engineering Dept.,
Technical University of Gdansk, Poland
"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,
"CD-CHECK was able to quickly and efficiently determine the source of our DVD mastering problems.
It’s ease of use and low cost made this one of the best purchases we’ve ever made. It has probably
saved our company and our clients hours of frustration and extra costs. CD-CHECK has become an
integral part of the daily calibration and maintenance of our DVD and CD hardware."
Jeffrey R. Fish, President, Filet Post Production, Canada
