Subject: Casio DA-R100 vs. Denon DTR-80P
Organization: Taligent
Date: Tue, 29 Sep 1992 18:51:14 GMT

What is the difference between the portable DAT recorders
made by Casio and Denon?  How did Denon modify the Casio unit?
Here's what I've found out so far, but it's not conclusive:

Comparison with Denon:
---------------------
Denon America: Mr. Toshita, Service Manager, (201) 575-2810
Q: Did Denon modify the Casio DA-R100?  If so, please be specific.
A: We can not say for sure what is different; why would we say that?
It's *probably* in the D/A converter and the power supply.
Q: Have you presonally listened to the Casio?
A: No.

Casio America: Ed Alstrom, (201) 361-5400 x402
Q: Is the Denon DTR-80P really a Casio DA-R100?  Does the Casio 
have a 64 fs A/D and a combined 18-bit, 1-bit 8 fs D/A?
A: Denon did little more than put their name on it.  
They are essentially the same.

My answer to Mr. Toshita was if you can't tell me exactly 
what's different, why should I pay $300 more for your unit,
when it sounds exactly like the Casio? In other words, I have 
to guess that there's some hidden increment in quality,
when what I can readily perceive appears equivalent.

Price:
-----
Denon price $799 at the Goodguys (includes dry cell pack). 
+$79.95 for nicad pack
+$29.95 for case
Total $908.90

Casio price $585 at Uncles  (includes nicad and case)
+$35 for Denon dry cell pack (works with Casio)
Total: $620

Notes: 
The remote control Denon RC-423 ($39.95) also works with the Casio
Denon does not warranty a unit purchased at an unauthorized dealer
Denon warranty is 1 year parts and labor, Casio is only 90 days 
parts and labor

Listening Test:
-------------
R: Reference system: Denon DCD-1290 with dual 20-bit converters.
C: Casio DA-R100
D: Denon DTR-80P
Disks: Chesky Jazz Sampler and Audiophile Tests Vol. 1 & 2 and 
assorted music.
In particular track 25 on Vol. 1 - "Bonger Tests"
and tracks 60-70 on Vol. 2 - "Converter Resolution Tests"

(1) AD/DA - analog input, anlalog output

(2) DA - digital input, analog output

(3) AD - analog input, digital output to preamp with 3 digital inputs

When playing back music - instruments, synthesizer, acoustic,
classical, jazz, ethnic, etc. there was little difference if any.
When playing back the Chesky tests, the reference system R was 
always better than both the Casio C and the Denon D.  In some 
cases C sounded better than D.  In particular, and interestingly 
enough in agreement with an earlier posting, the resolution tests
at -40 dB and -60 dB sounded cleaner - less distortion - on the 
Casio in test (2).

Note: The Chesky liner notes claim that the Bonger should sound 
like a pure tone, but none of my converters manage its decay without distortion.
 They must bepretty far from perfect if ideal conversion 
had not distortion.  Although there may be some on the recording itself, 
even if they did use a 128 fs A/D at Chesky.

As far as I know, B&O builds their own stuff.  I am sure that certain
parts, like CD player mechanics, come from other manufacturers.

B&O is noted for their slim (not tall) styling, and is on the upper
end of the quality range in the consumer electronics field, approaching
audiophile.  I have a B&O 4004 linear tracking turntable, which I like
very much.  I have heard of some criticisms of the lack of a damping
pad on the platter which may be valid, though the grip on the record
by the center post makes this pretty much a non-problem.

One of the local electronics hobby mags reviewed a pre-release DCC recently.
The reviewer was a total techno-junkie who hardly ever criticises anything
new and flash. He loved the DCC, BUT said the analogue playback measured
and sounded pretty bad. He even wondered if Philips were deliberately
making analogue cassette seem worse than it is, to encourage upgrades....

This was without measuring wow & flutter, BTW (he forgot!). The frequency
response was bad on all tape types. This on the expensve 900 series home
deck, I wonder what the portables will be like (if they ever arrive).

dbx is quieter and less fussy (less tape-deck-dependent/tape-sensitive) than Dolby C
Dolby C. A working NX40 does not need to be critically matched to the 
tape deck to work very well (make SURE the pots are at midpoint or below!---
the pots on the rear, that is). On traansient-type material at low levels,
like piano or bongos or wood blocks or baseball bats, which lacks a lot of
HF masking overtones, it is possible to hear tape-noise modulation w/
dbx. One partial solution is to record at as high levels as practical short
of distortion. Sometimes with low-level piano it is never satisfactory;
sometimes it is.

Dolby C is better on such material (sounds better sometimes), and its 
own noise-
floor modulation is really minor. For some listeners this may be preferable.
For others Dolby C's slightly higher noise floor (hiss) makes dbx (type II
in this case) preferable. Dolby C is much touchier about proper tape deck
care and feeding and alignment and tape-matching, as noted.

dbx is no more flaky with dropouts than C, in my experience; dbx does
NOT "double" FR errors (cannot double them), as an old and persistent
myth has it (there is only one gain at any given playback point---think 
about it).

Dolby C is also barely listenable without any decoding. dbx is, really, not.

Try the NX40 and see what you think. Dolby B in combo with the NX40
works very very well (Dolby B "inside" dbx type II), can sound better
than any of these systems alone, and is relatively bulletproof. You
will always have to play the tape back on the system it was made on,
though---no sharing with friends, no use in the car, etc.

Most of the recordable units are still priced for the professional
in the high 4 - 5 figure range.  The discs that you record are WORM
and will run you more than a blank DAT.

I do not believe that a WMRM drive is available that produces a CD that
"obeys" the RED/BLUE book standards for CD manufacture and playback.  While
WMRM drives exist (MO for one) the CD these units "cut" cannot be played
back on compatible players.

Vinyl seekers & lovers,

I like to recommend the service of Mr. Hector Acevedo to you. 

First I like to state that I have no business connection to Mr. Acevedo
nor were we friends prior to my dealing with him.

I connected to him by chance. We have exchanged phone calls and mails.
Mr. Acevedo has a home based samll business which supplies records to record
Lovers. Recently, I bought Lyrita SRCS-92 Finzi: Concerto for Clarinet &
Strings, SRCS84 Finzi: A Severn Phapsody and SRCS-131(2-LP): Elgar's
Symphonies 1 & 2 from him.  These Lyritas are all Nimbus pressing and are
all in mint conditions.  Mr. Acevedo charged me more than reasonable
price which I could not even buy the same non-Nimbus pressing records
on the market.

Through our phone conversations, I learned that he was once an owner of 
High End Streo store, and was the president of Florida Audio Society.
He is very knowledgeable in Classical, Jazz and other types of music, as
well as in hardware. I was very impressed by him.

His service has been focued on 50's - 60's Jazz, and he has customers not
only from N. America but also from Europe and Asia. Recently, he has started
to deal with Audiophine records. Mr. Acevedo is a very resouceful person.
From my dealing with him, I beleive that he is an honest person and is
really enjoying what he is doing not only from business point of view.

So if you are vinyl seekers & lovers, you may like to get in touch with
Mr. Acevedo.

His address & phone number:

	Hector Acevedo

  I own a Nak Cassette Deck2 and think it's probably a miracle tape deck
for the price.  I was also considering the top of the line Denon at the
time, but the Nak sounded way better (in my opinion) in recording and in
playback than the Denon.  The Denon are also very good, my 2nd choice to
the Nakamichi, and have many more features.  As for Sony, Sony stinks!
I guess you could get the cheapest Sony ES for the same cost as the
Nakamichi, but the Nakamichi has better sound quality while the Sony has
more features.  Yeah, none of the Nak's have HX-PRO, not even the
CR-7A's or Dragon's because their decks are "superior" and they also
manufacturer pretty good heads.
  I've owned my Nak for 2 years now, and have not had a single problem
and don't regret my purchase.  In fact, I listen to my Nak tape deck
more than I listen to my CD player!!  What it all boils down to is
wheter you are willing to sacrifice some of the features that other
manufacturers offer and the extra head for monitoring during recording.

I bought a Proton D540 integrated amp from them about 2 years.. maybe 3 years
ago.  It was an incredible deal.  I think it was around $218.  But three days
after I received it the protection relay went out in one channel.  So I asked
to return it and exchange it for another.  No go-  I would have had to pay
to ship it to them and then waited for the part to arive, and then waited for
them to ship it back.  So I played around and figured out if you applied  
pressure to one side of the relay it would work.  So I propped it up until
I got back to Mpls where there is *one* day service if the part is in.  It
was fixed under warranty.  I beleive the price I got was really close to cost.
He initially charged me 3% extra for amex, but when I couldn't exchange it 
for a new one I called amex and they were upset to hear I got charged 3%
additional for it and refunded my 3 % probably at Sound City's expense.  So
don't count on any service from them.  As far as I know they are authorized
dealers for everything they sell. But ask anyway!  Never buy "new" gear
from an unauthorized dealer!  If you buy from an authorized dealer you can 
have it fixed at *any* authorized repair shop under warranty...  if it's
unauthorized... you're screwed!

Sorry, a DCC deck is not what you want.  Although the DCC decks will play
back an analog casette, they will not record.  Perhaps later some makers
may add analog record capability.

I suspect that the tape transports will be fairly good, especially with
lateral tape path control, because of the need for tight lateral control
to make the DCC tracks hit the multiple record/play gaps lined up on the
DCC head.  On the other hand, due to digital buffering, DCC could withstand
a fair amount of wow and flutter and still work just fine.  But the analog
audio would be degraded.  So if they are looking to cut costs, this would
be one area.
