I don't have the A/V receiver, but I bought a Kenwood KR-A5040 this
summer and I love it.  As the other posted said, Kenwood doesn't pack
them full of techno garbage like sony and panasonic (and lets not

as the center of my modest music system.  In short, I highly recommend
Kenwood for the money.  As far as comparing it to separates, well

For Subwoofer under $300, the best one is probably made by Dana Audio
model Sub 1.  It's a cylinder about 1 foot tall.  Having one of their
mini monitor speaker (Model 1), I am very happy with their sound.  I
recommand you give their subwoofer a try.  They only take mail order
and you have 30 days to try it.  They're located in San Antonio.  I
don't have the # handy, but will look for it if anyone is interested.
(Just look up any issue of Stereophile)

Celestion also make a subwoofer. I don't know the detail, but I believe
it's under $300.  Also Hsu research made something similar to the Dana
audio for about $400,  and they're located at Gardena, CA.

That's very true.

I called up Carver and they told me the opposite is true. They take time to
be played to massage out stress and strain incured during manufacturing process.

Well, the whole thing here is not to idolize Carver or anything but I think
just due has to be paid to Carver speakers. Personally, I don't like anything
else made by Carver. The speakers are the only Carver stuff I own. For 
amp/preamp, I would prefer Mondial stuff.

   I took a look at Philips' DCC900 ad. Though it mentions that the
 technology uses a "coding" scheme in the recording, the ad claimed
 flat out that the sound quality is _equal_ to a CD. This is, of
 course, a lie; but is it grounds enough to, say, sue Philips for

I don't know if your assertion about deposition is correct.

The SEM's I have seen of gold v.s. aluminum metal interconnect
systems in IC's clearly show that gold has better step coverage.

I doubt if the difference is of importance to the relatively imprecise
systems imployed in CD players. I don't have the facts but I suspect that
the feature size is huge compared to that of typical IC's. If I'm
wrong on that assumption then there actually could be something to it.

I will also defend the planar approach. My video system is a pro-logic system
using Magnaplanars. I power them with Adcom 535's, rated at only 60w/channel.

I have a 25 x 35 foot listening room with an 8 foot ceiling. Most of it has
thick carpeting. One long wall is lined with books, the other is all glass
but has curtains. The wall behind the monitor and main speakers is a continuous
curtain. The room has many many problems and the speakers are in VERY
compromised positions. The room is, however, fairly dead overall.

When watching high dynamic range movies like Preditor, Lethal Weapon II,...
I can only run the system at about .25% on the master volume control. The
dynamic range is stagering. Although you can comfortably hear the dialog,
when a big explosion goes off or a high impact score peaks for effects it
blows me out of the room. I even find myself riding the volume sometimes.

I would NOT want more dynamic range. In fact I am thinking of trying out
some compressors and/or limitters to reduce it!

Just another persons experience. BTW I have plenty of conventional dynamic
speakers and like (at least some of) them too.

I also listen to alot of rock on this system and am generally pleased
(never satisfied though B^). The planars are a little lacking in low end
and I am currently without subs (and funds :-().

Hi!  I was just wondering about class A amplifiers.  There is a shop
in my city that is selling kits to build a 'pure class A amp'.  The
specs say that it delivers 250 watts/ch into 8ohms and 350 watts/ch
into 4 ohms.  It does have an enormous heatsink but I'm still wondering
whether it is a good buy at about $100.  It isn't really class A is it?

They also have another kit that produces 50 watts mono and is also
supposed to be class A.  This seem a little easier to swallow.  I wouldn't
mind some responses.  Please post to the net because I think that these
kits are quite common.

Thanks

Subject: Re: Amp Distortion vs. Source Distortion
Date: 18 Dec 92 17:21:47 GMT
Organization: Division of Electrical Engineering and Computer Science, UC Davis

It is well known that an amplifier dirven to distortion can damage speakers,
and someone asked whether program material that contains a lot of distortion
is just as harmful.  An amplifier driven to distortion produces a lot of harmonics,
and a great deal more power is produced at higher frequencies (even ultrasonic!). 
Hence, the first thing to go in such cases is usually the tweeter.  If the amplifier
is cleanly amplifying a distorted program, the high frequency content would have to
be somewhat less than that same amplifier driven to clipping.

My experience suggests that if the amplifier is not clipping, there is little chance that
the speakers will be damaged BY THE SAME MECHANISM as when the amp is clipping.
The program material you describe could well have more power in the midrange
and highs than the typical power spectral density used to assign a power handling
rating to the speaker, so caution is advised.  But I think you're a lot safer
than if the same sound were due to your amplifier clipping.

Also, I think that studies have shown that distortion increases perceived
loudness beyond just the added power of the extra harmonics.  If you set
up a really clean system, and ask people off the street to turn up the
volume until it is "loud", they will tend to turn it up to where something
begins to distort.  So maybe that awful sound  is not actually delivering
as much power to the speakers as it would seem.

I wonder if anyone could comment further on how power handling ratings are
assigned, and what sort of power spectral density is used as a model?

Yes, It should be.  Heres why:
   This logic applies to DCC only.  Remember the posts regarding how CD
prices may rise, and DCC will assume the current CD pricings?  By
telling them that it is equal in sound quality, they would get away with
charging CD prices for DCC, and the extra cost of CD's would be for
'random access convenience'.  Thats the only way they could get away
with raising prices for CD's.  Customers would be told 'Hey, just go
DCC.  You aren't missing anything.'  This is a lie.  If DCC was a car,
it would be regulated, and they couldn't say that.

   It is wrong and should bluntly say Near CD quality.  Think about
TV's.  Can you imagine Phillips charging $4000 for an IDTV (wide NTSC
picture) and saying it was HDTV quality (it's only a third the
resolution, just the same aspect ratio).  Thats the equivelant of saying
a Malibu is as fast as a Porche, just a different exterior.  It is a lie.

    The only benefit of DCC applies to DCC makers.  CD's cost a buck to
make each!  Tapes cost more (especially with the 'quality' tape required
to make DCC).  Consumers don't benefit (If they're so sonically stupid,
they should stick with analog cassette; if they're audiophiles, go DAT).
 Record companies only benefit because they have a new format that they
lie about its benefits, but really makes poor reproductions.

    It is not CD quality.  I have heard the unit (Phillips DCC-900), and
the only time it is CD quality is when it and the CD player are OFF!

>Is it compatible to combine the DR-7 and the M&K sub?
   
   Yes it is.   How did you intend on hooking it up?

   The M&K Subwoofer can be driven directly from a preamp output or
   from your speaker outputs.

   In the pre-amp connection, the regular speakers would be attached
   to your normal speaker outputs from your main amplifier.   This
   sends a full range signal--including bass to the main speakers.

   If you hook the M&K to your amp's speaker outputs, you can hook
   your DR-7's to the M&K subwoofer.   However, the speaker output
   of the M&K is still a full frequency signal...so you DR-7's will
   still be receiving a full range signal including bass.

   If the DR-7's have problems with the bass level (it will really
   be unchanged, the sub doesn't add any), contact M&K and they can
   give you details on how to insert a high-pass in series with the
   DR-7's.  [You shouldn't have problems, but just in case...]

   M&K ships most of their subwoofers with the bass cutoff (or
   crossover) frequency set too high, IMHO.  Most sound much better
   if you cut them off at 80-100 Hz or less.
