I sold hifi stuff from about 72 until 79 or so, and the midrange decks
that I bought very cheaply from Panasonic/Teac/Akai/Sony/Onkyo would all
do at least 17K absolutely minimum, and many would go over 20 or even
22K. Most of them could record an LP well enough that it was very
difficult to tell the difference between the copy and the original. Some
actually had a slight bass boost, kind of a bonus back then, as records
had the bass cut most of the time.

I paid less than $200 for almost any of those decks, and if they were on
closeout, it was closer to $100. I still have a Technics deck I bought
in 1979 for a whopping $119+ shipping, and it works perfectly. I
recently bought another Technics deck, the same model as the first one I
bought at 14 years old. I got it from a guy on Ebay, and it looks and
sounds like it just came out of the box. Mine lasted over 27 years
before the take up reel motor died. I tried and tried to find one, and
finally scrapped it, only to find a perfectly working, but cosmetically
challenged one at Goodwill a couple months later. The one I have now is
slightly different, as it turned out there were four slightly different
versions of the same model. Panasonic/Technics did a lot of that with
cassette decks for some reason. A friend of mine's brother has the same
deck, with slightly different fonts on the labels, and the Technics logo
is smaller, too. My original one had sliding level pots, it's the only
one I've seen like it, except in pics, but every other one I have seen
in person has regular rotary pots for the level. The panel layout shows
that the sliders were the original design as there is a lot of wasted
room all around them.

I never could take 8-track sound for very long, the wow drove me up the
wall. Not to mention the track changing in the middle of songs.

Not a Nakamichi, nor a Denon, but an admittedly above average Sony, mine
will wind off a bit of tape from the spool, record two tones, rewind and
evaluate to determine the exact bias for that particular formula tape,
and when combined with the headroom expanding version of Dolby (HX-Pro)
can deliver frequencies way above my current range. The sound level

I think I mentioned this kid six or seven months
ago in here. But there is this kid on youtube,
goes by "CassetteMaster"....he definitely has
a love for bringing back to life older cassette
players / eight tracks....just about anything.

It's good to see IMO, a kid with the love he has
for the older electronics.

Except the Nak sounds way, way better. Even high bitrate MP3's sound
pretty bad, if you can still hear. They do sound a lot better than

1) One cares about whether one can get 24KHz reproduction out of a tape
machine (or any other reproducer) beause the flat response curve at the high
end actually affects the sound at lower frequencies (the characteristics of
musical instruments are that many carry large numbers of harmonics, which,
even if you cannot hear the harmonic itself, would change the intrinsic
sound were they not there at all)

2) There is NO mp3 player that can as accurately reproduce a complex audio
waveform as well as a high end cassette machine. I don't care how many
samples you take of a complex waveform with an ADC/DAC system, the resultant
playback waveform will never represent the original analog waveform as well
as a high end analog device. Even a simple 1000 Hz sine wave will not come
out as a pure sine wave after digital conversion, it will be a series of
stepped square waves. You may not be able to tell the difference with your
ear, as long as there are enough of those little steps, but that's not the
point. The point is, it will not "run circles around" a high end analog
device.

If you take a look at a 1khz square wave after digital
conversion, you'll see ringing at both ends of the flat top. You'll
see that same ringing wherever there is a hard rise or fall. Is it
audible? Oh yeah. More so on a naked square wave. Less so in complex
music. But you can hear it.

You'll see this wherever there is hard digital filtering, such as
anti-aliasing on CD players. You'll see it where there is copious
amount of data loss, as in MP3.

An MP3, at it's best is a 4:1 data loss. The songs on iTunes and
elsewhere are mostly 10:1 data loss. Sometimes more, sometimes less.

Noise may be reduced, but it's hardly high fidelity audio. And
though cassettes have their many flaws, a properly set up Nak will
have more noise, but far less digital artifacting and zero data loss
than any MP3.

Sorry. Apples and oranges.

I once built a two transistor pre-amp that was flat from 10 Hz to over 2
MHz. Thing is, it didn't have all that good of a distortion figure.
Digitally reproduced analog waveforms have distortion. There is simply no
way around it. You cannot make a true, perfect sine waveform out of a bunch
of square waves. It can't be done.

Further, the universe is most certainly not digital. About the closest thing
you get to digital in the universe is a hydrogen atom. But even the radio
frequency wave output from a hydrogen atom is a sine wave: analog. Digital
can only be a representation, in various degrees of fidelity, of an analog
signal.

Yes, but the error from a perfect sine wave may be extremely small. In fact
much lower than the noise in most analog recording methods.

The same can be said for analog recording systems. They also introduce noise

I work with a lot of 20 to 30 year olds and many of them have a severe
hearing loss, listening to their car stereos is nearly torture for
anyone who can hear normally, they almost all have a huge boost on the
top end. It sounds horrible, but they think it's great. My one friend is
deaf from jet engine noise, but he's 60 years old, not 23. By the time
these kids are 50-60 they will be stone deaf.

An MP3, at it's best is a 4:1 data loss. The songs on iTunes and
elsewhere are mostly 10:1 data loss. Sometimes more, sometimes less.


Isn't equating compression ration or data rates to data loss a bit
misleading? Sure, MP3 and AAC are lossy codecs, but a lossless codec such
as FLAC reduces the data rate without loss of the original content. The
amount of original signal lost by the use of AAC or MP3 compression is much
less than you imply with your numbers.

Noise may be reduced, but it's hardly high fidelity audio. And
though cassettes have their many flaws, a properly set up Nak will
have more noise, but far less digital artifacting and zero data loss
than any MP3.


I would expect an analog system to have no digital artifacts. But, you admit
there is more noise, isn't that also a loss of 'data'. But you also ignore
any reduction in bandwidth that occurs with magnetic recording. Also, at
its best the Nak may have higher distortion than a high end MP3 player.

Cassette decks have their BW specified at -20 db because at higher levels,
head/media saturation limit useful bandwidth.


There are several technical criteria that must be met with digital
recording so that it can equal analog. These criteria must be met in
both directions, analog to digital, and then digital back to analog
being a complete process.

The sampling rate must be twice the highest frequency you want to record
so if the analog frequency is 22 KHz then the minimum sample rate is 44
KHz. A higher sample rate is better. For this sampling scheme to work
well the conversion in either direction should be low pass filtered.
This scheme has the 22 KHz sine wave represented by two steps, which is
very coarse.

The analog filtering will help the reproduced analog look like the
original recorded analog signal but the conversion sampling has several
types of imprecision to contend with besides sample rate. Just as
important are sample levels. The smaller the sample level the more
precise the reproduced analog will be.

So the two main parameters are the number of samples made in time and
voltage or to look on a sine wave on a graph the horizontal and vertical
axis. The smaller the steps in either axis the closer the digital
stepped waveform approximate the analog. Then a low pass filter smoothes
out the tiny steps as a way of "polishing" the digital waveform to look
even more like the analog.

The problem with the above conversion scheme is the sample imprecision
in time and voltage, which leads to conversion noise and distortion. The
precision can be improved with an increased number of steps in either
axis. Increasing the number of voltage steps means the sampling number
must be numerically larger and increasing the sampling rate increases
the number of samples that must be processed and stored for the same
length of the recording so higher quality means bigger numbers and more
of them.

This is a big problem for digital recording, storage, and reproduction.
If you want high quality you need the electronics to operate rapidly and
generate more data requiring larger storage. The electronics operating
rapidly consumes power and large data storage also costs more money so
the solution is low sample rates and small sample numbers.

Along with small sample numbers and low sample rates, data storage
requirements are further reduced with compression algorithms that are
lossy or in other words further distort the data. Here "lossy" means
some of the data is thrown out and not saved to storage.

The financial cost of these problems also burdens the transmission of
digital data similar for the digital storage cost. Higher quality means
higher transmission rates similar to larger storage requirements. Higher
transmission rates means the signal must occupy more spectrum. For this
reason and others the IBOC and DRM sounding "better" in the same band
space is just plain BS.

So basically, regardless of the sample size and rate used you have
inherent sampling and anti-alias filtering distortion so the converted
analog waveform can never be as good as the original but using more
power, band space, and storage it can be close.

We are all used to the continual improvement in electronics where they
run faster with less power and storage becoming cheaper, smaller, and
lighter with time, so with time all this can be overcome except the
amount of band space needed for transmission. Here improvements in
electronics cannot overcome basic physics.

You need to be more generous to yourself and not be so quick to
dismiss things that overwhelm your intellect.


This is a good analogy to your missive.

Sound that is too LOUD will blow off some of those tiny little hairs in
the Ear canal.That impairs hearing too.

Eh, what did you say? I can't hear you!

Clean that nasty old wax out of your ears and you might hear
something,,,, and stop pickin them boogers out of your nose!

Eh, hold out your cup and catch this booger.

What's an iPod?


I read the article also. *Most people look at the cassette as
equivalent withthe *8-track tape. *But I bet these same people would
be shocked to find out that some of the better cassette decks had way
better specs than a Ipod. *I have seen some of the Naks with freq.
response to 27 khz and my Denon, which was a mid-level deck, has freq.
response to 23 or 24 which I know is more than you can squeeze from
digital at even the highest bit rate. *I'm just sayin'..........


Sad. *You can't hear much above 10 K; *why do you care about 24?

You can buy a credible MP3 player for $20 that'll run circles around
your POS Nakamichi.


Reality check!

I have yet to respond to any post on this group in over a year, but
after 34 years in high end audio (sales, technical sales training,
product planning and development on three continents...) I couldn't
resist...

Frequency range has very little to do with it. ANYTHING that
compresses by any form of digital "bit grooming" can loose vital
information. Case in point... A fairly high priced MP3 recorder/
player with minidisc and computer MP3 capabilities managed to lose the
bells (actually a glockenspiel, I believe) at the beginning of a
Phoebe Snow track that I used as a demo for years (many other
examples, but this is a case in point). Digital compression can lose
textures, details, imaging, transient information in ways that is
COMPLETELY foreign to the human psycho-acoustic mechanism. Our ears
and brain can "fill in" information lost by anything as natural and
simple as bandwidth limiting, BECAUSE IT HAPPENS IN NATURE ALL THE
TIME! If we, as a species, have had to deal with bandwidth limiting
by something as simple as distance or intervening materials such as a
drape or some walls, etc., WE HAVE ACHIEVED THE ABILITY TO RECONSTRUCT
THE MISSING HARMONIC INFORMATION. And we can pull information out of
the noise floor of analog recordings by dithering.

I used one of the few decks that can trump all of those mentioned
above (although the Nakamichi units were excellent), the Tandberg
3014A, and have been able to produce recordings that (on over
$60,000.00 of amps and speakers) rivaled the very best digital
technology available at the time (2005 or so), and was only lacking
compared to an excellent virgin vinyl LP on $10,000 worth of
turntable.

As for bandwidth and digital technology... Anything that has a bit
rate as high as SACD or Meridian lossless packing on DVD Audio can
produce a bandwidth of 50 kHz and beyond. And that is your best hope
of achieving a recording that can compete with high end analog,
PERIOD! I have some SACD remasters of mid-1960 Rolling Stones
recordings that sound BETTER than the British virgin vinyl recordings
of the exact same performances. Of course, digital is quieter, but
I've already mentioned that we can dither significant information that
is below the noise floor in an analog recording. The "noise floor" in
a digital recording is the point of no return. NOTHING exists there,
it's all truncated. Ignored!

I know of NO MP3 device that can compete with the best Tandberg,
Nakamichi, Harman Kardon 400 series CD recorder regardless of the bit
rate. THEY DO NOT EXIST!

And a truly audiophile turntable with a moving coil cartridge can
trump any of the above in most respects, but that's another
subject...

Maybe so but the price is prohibitive except for the elite
billionaire.

For far, far less dinero a very decent SA-CD player, a modest 5.1
channel surround sound amplifier, and 5 mid-priced full range speakers
and subwoofer will equal the best mucho dinero mega-bucks elite vinyl
sound system TO THE VAST MAJORITY of listeners.

A very good Universal SACD/CD/DVD player can be had for for $200-$600
A very good 5.1 / 7.1 channel home theatre amplifier can be had for
$1000-$2000
A very good set of 5 indentical full-range speakers can be had for
about $2500 used (recommended on a budget) or at least double for new
speakers.
A very good subwoofer for about $1000.

TOTAL for an very good "audiophile system for the rest of us" - less
than $10,000.
And if you are prudent you can do it for half that price. (Used
audiophile speakers are a bargain.) Well within reach of most
"working" music lovers.

If you are foolish enough to spent money on a vinyl LP system and
expect to surpass the above $5K-$10K system than you had better take
on a second or third job.
