Telarc has put out a number of Super Audio CD's, this being one of them.

Hopefully, you have a Super Audio CD player (Sony) and
amplifier/receiver that
will accept it's 6 channel output with each channel having a dedicated,
discrete input. The amp/receiver must be then put in direct, 6 channel
mode, (often called "Multi-Channel Input" driving a main left, main
right, center, left rear, right rear and subwoofer. Most Telarc SACD
are hybrid, meaning they will also play on a conventional CD player but
you will lose superior fidelity of a SACD recording. Conventional,
digital "Surround Sound" ... be it 5.1 or 7.1 is *not* SACD.

In addition, SACD's are recorded completely differently than a regular
CD. It's complicated and hard to explain but it uses phase modulation
rather than amplitude modulation. Basically, it's much like the
fidelity difference between AM and FM radio. Many people don't realize
that AM radio's bandwidth is limited to 10Khz which means it can't
broadcast the full audio frequency spectrum that the human ear can
detect. FM, in addition to being frequency modulated rather than
amplitude modulated has a 200Khz bandwidth.

The only negative about SACD's is the limited number of them available
and the fact that Sony is the only manufacturer of SACD players (last I
knew).




My criteria is how much do the "super" CDs sound like a live concert.
The few I have heard on really good sound systems sound over-engineered
to me, sort of like an AUDI car. They sure as hell don't sound like you
are sitting in the expensive seats at a serious music concert.

BTW .. a true "audiophile" (which I am *not*) would be dismayed at the
sight of a bass or treble control or any other circuit that "colors" the
sound of the recording. I am not that far gone with this stuff. Living
rooms and listening areas vary acoustically and really can't duplicate a
concert hall or your local live music hot spot.

I've played with audio stuff for years but have pretty much lost
interest in it. I am cleaning out our house and you wouldn't believe
the gear I am tossing. Came across a big box *full* of directional
audio connects that must have cost a fortune to accumulate over the
years. Problem is, I never bought into the "directional" BS to begin
with. The idea is that the capacitive reactance changes along it's
length and the directional cables compensate for any losses.
My problem with that is that at audio frequencies there is *no*
capacitive or inductive reactance generated anyway. At higher freqs ..
like RF ... yes, the transmission line becomes reactive to frequency but
not at audio freqs.


I'm in the market for a new computer sound system. The one I've got now doesn't do
justice to the 'normal' Telarc.

I bought my wife a Bose "computer" speaker set that is as good as the
old sound systems we grew up with that had coffin sized speaker boxes.

I have a Bose system for the family room - TV and stereo. With my high frequency
hearing loss, the Bose speakers sound really 'bassy'. What I need to do now is go to
Best Buy and listen to some. Which Bose set did you get?

I have some "M-Audio" speakers hooked up to my imac.

Like these:

They sound pretty good.

Thanks, I'll look into them. Do they get enough bass without a subwoofer?

It's subjective. I think they do. Your mileage will vary. If you order from
anazon returns are easy

I'm very happy with these. USB powered, but plenty loud for a
PC.

True. The best I could do is compare them to each other in that environment. Also,
most of my listening to the computer is from about 4-5 feet. Doing the same in a
store would probably negate the effects of the huge area.

We are saying the same thing. I just left out the the 455Khz
intermediate freq for simplicity. The BFO (controlled by your tuning
dial or pushbutton) is tuned to the carrier freq however, as I recall
and not to the fixed, IF frequency. If that were the case you couldn't
select any particular broadcast frequency.

It's a matter of standard terminology.

The local oscilator (LO) is what allows you to select stations by
frequency. The BFO is specialized for CW and SSB reception and many
(most) radios do not have a BFO.

Where does the cats whisker fit in there? ;-)

That's easy, the cats whisker is basically a semiconductor diode that
demodulates the AM signal. Of course the availability of vacuum tube
diodes and packaged semiconductors made the "whisker" obsolete. :-)

The sub woof says Companion3 Series II. It is a sub woofer/amp box
with 2 small satellite speakers. I got it at Costco for her to use by
her chair in the living room. I have a Creative set by my chair.
They are all hooked to the audio out of the TV so we can set the
volume to what we like for movies and such. I also use mine at night
after she goes to bed to hold the noise down. My satellite speakers
are mounted on the back rest of my chair so they can be set pretty low
and I still hear it OK. At night I turn down the sub woof.

I was just screwing with you guys. I did make a very simple radio when
I was a kid using the brand new germanium diode for the detector.
There really wasn't much to it since it was basically the old crystal
set design.
The next radio I made was a 3 tube deal that was one of the projects
in a 12 week (by mail) electronics course I took. You got a box of
parts every week and a new project building on what you did the week
before along with a bunch of training material and a self checked
quiz.
It was pretty good training for a kid and the radio worked pretty well
for what it was. It got me interested in DXing

Thanks. No new ones on Amazon, but Ebay has several at auction in the $100-150 range.
Might keep my eye on them. I do like the looks.
