    I seemed to have generated a minor stir when I reported that
the salesman I spoke to at American Audiophile Inc. "trashed Yamaha
and Denon."  Yes, now that I'm home and was able to check the specs,
not only was he being ridiculous, he was downright wrong about what
he said.  He said that Yamaha/Denon have this great big warning
that you can't hook up any speakers rated at less than 8 ohms.  Well,
I'm holding the brochure here in my hand for the Yamaha RX-460 55w/ch
receiver:

   "Low Impedance Drive Capability:

    Speaker impedance can significantly influence music reproduction quality.
And although speakers are rated at a certain level (such as 8 ohms), actual
impedance will vary widely as the audio signal changes.  Yamaha receivers
have special low-impedance drive circuitry, enabling them to competently
handle loads as low as 2 ohms."

   The salesman also said that Yamaha receivers don't have any bass,
which is a totally unfounded claim anyway, so I ignored that too.
But I do have to say I was taken by the Carver unit he was showing me
anyway.  The Carver receiver (HR-732, 60w/ch) looked so solidly constructed
I could probably get away with tossing it off the roof of a building.
According to Stereo buyers guide, all Carver receivers feature
Sonic Holography, Ambience Enhancement, and Proprietary multipath
suppression circuitry, but he didn't mention those features.  I didn't
look hard enough at the unit to see any markings/toggle switches for
the first two though, so they might be there.

   Anyway, thanks to everyone who has helped so far.  Now that I bought
the Paradigm phantoms, I'm still looking at purchasing a receiver.
People have steered me towards NAD, but most mentioned that Yamaha
and Denon are good units.  NAD makes a 40w/ch unit for the same money
($499) but I think the extra power on the Carver would be desirable,
especially if I'm shelling out the extra $200 or so to pick up the
Carver anyway (I just might do this, anyone agree/disagree?)

   Well, that's the story so far (-Fish, Marillion).  Happy Holidays
to everyone!

What makes you believe that my Carver Amp will mask the differences?  Is this
because of the transfer function 'tweaking' that carver does to his amps?
If this is the case, then why wouldn't the higher end tube stuff (which
carver attempts to immitate) do the same thing, since those amps also add
artifacts in their own transfer function.

Also, I don't have any intention of purchasing the #30, (my wife would either
kill me or have me put away!).  But I do like listening to what's new out there.


I'm also looking forward to listening to DCC and MD and comparing them to
my CD player.  I know that audiophiles are cringing at this new devices, but
I don't care what they think especially if they haven't listened to them.  I
do believe that there will be some sort of perceptable difference between 
DCC/MD and CD but I'm not sure what it'll be.  I would have thought that the
audiophile world would have at least given these devices a listen before
castigating them.  I also believe that DCC/MD is nothing more than the 
record industries attempt at limiting 2nd/3rd generation copying though...
What are your thoughts on this matter, and do you think you could give thses
devices an objective listen, or have you been convinced without ever listening
to them?  (hope not...)

Heck, I can beat that, I've worked on an old class C amplifier
that used an 892B power triode (or is it tetrode).  The hardest
thing in using it was to keep the fool water-flow switches
working right!

And, yes, I've used Class C amplifiers as part of an audio-distribution

No! No! No!!!. You must use the sheilded part of the cable! Connect it to
the outer RCA connector on both th eleft and right side. This provides a 
ground shield for all wires. Check to see if you are parrallel to a house
wire in close proximity. That will induce hum as well, but not as much as
with an unsheilded cable.

Actually, it pretty much does say that as it applies to your personal
use of the copied recording.  It doesn't allow carte blanch pirating
and sale of copied materiual, but it more or less sez if you make
a copy of a recording and keep it for yourself you are OK.

In actuality, even without the Audio Recording Act, you could 
pretty much do whatever copying you wanted for yourself without
fear of any prosecution, etc.  The legislative discussions about
copying all seemed pretty intent on recognizing the home recording
for personal use as being OK.  Additionally, there's no documented
case of anyone ever being prosecuted or sued for making recording
tapes for themselves that I have ever heard about.

The royalty is a couple of cents per tape and on the order of 8-12
dollars per recording machine.

Here's the scenario - I have a Nak CR-3A deck with Dolby B and C, and
an Eq switch for 120us and 70us.  I have so far been recording on
chrome TDK SAX tapes with Dolby C and at 70us with excellent results.

My car deck has Dolby B and I think it plays everything back at 120us.
Unfortunately it also selects the tape type automatically and reads
my chrome tapes as metal.  Because of this, normal tapes actually sound
better on my car deck than chrome ones.

I'm going to get my deck optimized real soon and I'm not sure which tape
to optimize to.  Do I start buying metal tapes and record them at 120us
and Dolby B?  Do I buy normal tapes (optimize my deck to NORMALS!?!?)?
Do I optimize to chrome tapes and buy separate normal tapes for my car?
I'm sooo confused!  Any ideas?  Anyone....

I want to get rear-channel speakers for a Zenith television.  The
problem is, the T.V.'s amp is only about 5w, and I don't want to
spend a lot of money ($150 at the very most).  What are my options?
I thought about the following:

1.  Buy powered speakers.  I heard some really bad SONY powered
speakers.  They were tinny and I didn't like the fact that there were
two separate volume controls.  The only decent SONY speakers had two
small channels and a subwoofer, for about $150.  Even so, they seemed
quite directional, which is not good.  Wouldn't a subwoofer be kind of
weird for a surround system?  Where would I put the woofer?

2.  Buy real speakers, and some kind of mini-amp.  Does anyone make an
AMP for less than $100?  I'd feel kind of ridiculous purchasing an
automotive amplifier for my television....

3.  Are there other options?

You sound like you don't beleive in the #30.  Hmm.
 
First, It is amazingly good.  But that's not your
real question, is it?  You want to know how such
snake oil can work.
 
It isn't snake oil.  I don't know your level of
experience in digital and analog engineering, but
implementing D-A-Cs, clock circuits, and reconstruction
filters is neither easy nor cheap.  Arguaments of
"a bit is a bit" show a lack of understanding:
the problems in digital audio are predominantly analog.
Furthermore, there is no such thing as a digital signal
anyway, only analog signals which are interpreted by
digital recognition and coding rules.  Enough theory.
 
The Levinson #30 is, in my opinion, far and away the
best processor I've ever heard.  of course, for
$15 grand, it better be.  Is it 15x better than
a $1k processor?  Dunno, what do you value?

Max, JJ, and a few others can give the best descriptions
of what's so hard about digital audio.  BGut that's all
been done before, and I doubt they want to drag it all 
up again.  To convince yourself, just try to build one.
Its harder than you might think, and the performance of
off-the shelf components is just FULL of surprises.

Since you spent more than $79.96 for your NAK, I'll
presume that you DO hear SOME differences between
audio compoennts.  Right?

I'd look elsewhere.  The stories of problems with Sony CD players, both -ES
and non-, are legendary.  

One non-legendary data point:  I have a CDP-208ESD in my office system.  It's
okay most of the time.  But I have one disc that is scratched in such a way as
to cause this player to skip.  (The scratch is a sort of a spiral shape,
neither circular nor radial.)  The skipping is very repeatable.  Yet the player
does just fine through *all* of the "generated defect" spots on the Pierre
Varney test CD, so no one will look at it ("it's working fine!").  My other
players (Magnavox/Mod Squad 650, the Sony CD changer in my car, and a Sony
D-160 portable, all play this disc with no problems.  (Of course, the disc is
out of print and can't be replaced.)

Perhaps the Sennheisers will last longer than most walkmans, but a $50 
walkman *does not* sound very well. I would expect the differences in both 
sound quality and durability of $50 and $100 walkmans to be no less than
*huge*.

So buy a $100 walkman and throw away the el cheapo headphones later when you 
or your frend can afford the $50 Sennheisers.                 ^^^^^

What I would do is: look for a brand that is known for their durability and 
quality (e.g. Sony or Aiwa) not for their fancy bass eq. or auto reverse. 
You don't need anything but play, fast forward/backward and volume (and 
perhaps Dolby B). Auto reverse is wasted $ and makes the sound worse (loss 
of treble).

Then, when you have got the walkman, you should align the azimuth to match 
the recorder to be used. This is easily done by recording some FM-hiss (or 
music if you don't have a tuner) and adjust the azimuth screw visible near 
the play head on the walkman. The azimuth is correct when you get most high 
frequencies.

PS: I bought a $60 Sanyo once (with 3 stage equalizer) and it was terrible!! 
The speed was correct with fresh batteries and then it went slower and 
slower and slower as the batteries got used (started after ten minutes....). 
It was not anything wrong with it so I delivered it back and bought a $250
(NOK 1700) Sony (I regret that I sold it, it was real hi-fi!).

What?  If I recall correctly, Mr Pierce said class C amps are NOT used
for audio.

I worked on a class C amp in the military, it was an old tube type sonar
transmitter with big 4PR60 tubes for the output stage.  The tubes were biased
so high that only the top 1/3 of the waveform was amplified.  You could
get away with this type of biasing since the amp was only designed to
amplify a single frequency, 8KHz I think.

There is no way you can use a class C amp for audio, period.
And why would you want to.
