I'm curious. I know that many people with tube amps leave them on
24 hours a day. But I have recently been told that I should leave my
solid-state Adcom GFA545 on also. Why? Is this correct?

Most of the recommendations that I have saved have raved about
the bass quality or "liveness" of the reproduced sound of rock or
progressive (sorry, I don't know what call it) music. Youngjoon
and Marc Hauser (unimpressed Klipsch 5.2 review) were the only ones
to mention anything about the classical genre.

I've listened to the KEF 103.4s that Shiv Naimpally touts and was very
impressed. I plan to listen to the Vandersteen 2Ce this weekend.  Does
anyone else have any other suggestions for the type of music mentioned
above (i.e., 18th & 19th symphonic, chamber, opera music, and 50's
Jazz)?

Thanks and I apologize for the repetitiousness of this subject, I thought
being more musically definitive would provide for a better recommendation.

Thanks again,
Dave

You, sir, know for a fact that the answer is "yes". You have
consistantly ignored the history of this newsgroup that I

are well aware that several people on the severely skeptical

I am sure this request is asked alot so please post your responses so 
you can help others as well.

I can go as high as $1300, anything above that is a definite no go since
this will be stretching the budget enough.

I listen mostly to progressive rock (older Genesis) and I enjoy good
bass and a very live sound. I have looked at Theil 1.2s and also have
had Vandersteen 2Ces recommended. I have several live recordings and I
like the feeling of being there. I will also be purchasing a preamp/
amp as well at the same time ($900 budget) so the speakers and amp
will be a matched at time of purchase. Any suggestions? Thanks

No, you excuse me. The tweeters in McIntosh speakers are definitely not of
domestic manufacture. I don't believe the woofers are either, but am not
sure of late. As to the quality of those drivers, the last time I looked
at them, they would not rate in the same category (in a measurement and
mechanical inspection sense) to the kinds of drivers used in similarily
priced equipment. You may not like that fact, but that's the facts, tough!

Howdy:

I was at a local flea market today and found some guy selling old audio
equipment. Among the various old radios, tape players, etc. that he
was selling was an old wire-spool player--or at least, that's what I think
it was; I remember vaguely reading something about these things but had
never seen one before. There was a set of spools that came with the thing;
I assume they were pre-recorded. My question: is this thing a collectible,
or is it junk? The guy wanted $50 for it. If I had an extra $50, I'd buy
it just because I thought it was cool; but $50 will go a long ways to
buying some nice new CDs, if the spool thang is just a bunch of junk.

Now, speaking as someone who couldn't be called a "serious driver" by any
stretch of the imagination (I work out of my house and do little driving
most weeks beyond a trip down the street to the grocery--and have never
tried to do driving that pushed the limits of the car), I should point out
that a difference of a few pounds of tire pressure very definitely changes
the way my Porsche handles.  (In fact, at the recommended levels, it's a
little on the sloppy side, so I keep the front tires a few pounds above
that.)  Occasionally, when I take the car in to be lubed, they'll let out
some of the air in the tires to bring it down to the recommended levels
and as soon as I start to drive the thing, I'll know about it.  (Not
quite a double-blind test, but close enough for our purposes.)

On the other hand, on the various stereos that I own, the differences
between Kimber Kable and Romex and Straightwire Maestro and Belden
twinax are subtle enough that, if they exist at all, I would be very
hard-pressed to tell them apart.  (As opposed to, for example, the
much larger differences of moving the speakers a few inches or even
rearranging the furniture in the room.)

Trygve   (Hmmmm...maybe I ought to try inflating my speakers to a few
          pounds above the recommended levels....)

Definately worth the money are the two Chesky Test CDs/Samplers.  Not only do 
you get useful tracks to evaluate your system but the music tracks are among 
the finest available on CD (sonically).
     With their first Test CD, you get the LEDR test with which you can test 
your imaging.  I used the Bonger test to adjust the MSB trimpots of my player 
for optimum performance!
     With their other test disc, you can tests that are less useful for setup 
but are really fun.  Take for instance the tracks of natural sounds--amazing 
realism!  There's many more that just make you say "wow!"

Both are highly recommended.  Even if you could care less about the test 
tracks, buy 'em for the music!  You can't go wrong.

Not entirely correct. It does make a difference based on whether none, one
or both ends of the port are "flanged".

That is a port used in the conventional sense, that is, one end flush with
the outside of the cabinet (one "flange"):

       |
       |
       +---------------

       +---------------
       |
       |

Will behave noticeably and measurably differently then one that has no flush
ends:

               |
               |
       --------+-------

       --------+-------
               |
               |

While this last case is somewhat silly, it does illustrate the point.
Flanging effectively raises the acoustical mass of teh port slightly.

>
>If the port length is .75" then you may be in trouble.  The size of

Don't be tempted to adjust the port length vs. size by simply assuming
that it is the volume (and hence the mechanical mass) of the air in the
port that is critical. It's more complex than that. In fact, the change
will be less than intuitive. Changes in the port diameter ends up changing
the port length by roughly the square of the diameter change (not the
inverse, as you might expect). It's not quite a simple square relationship
becuase of the end correction needed, etc.

broadcasting power. I get the stations "ok" but on some of them

there is some background hiss.  I'm using a Yamaha CX 750 reciever with

Hi,
i had to learn that i'm probably looking for speakers in the $1000/$1500
range :-( since all those (not european build) speakers are much more 
expensive here. As example, the Apogee Centaur (never found a 'Minor')
cost here about $2800 (~4000 DM) without stands (grumble). 

I'm still looking what the B&W 804 will cost here around. At the moment,
i plan to involve the B&W DM640 and 804, I.Q. speakers (german made),
Apogee Centaur (too expensive) and Infinity RS60 speakers in a listening
session. I'm also very interested in the Thiel 2.2 which got good test
results here, but i still have to find a dealer here around where i can
listen to those beasts.

>BUT beware of these speakers !

The room i have is about 30 square meters. Also, i'm using two Denon 
POA 4400 mono amplifier. How can i get some information about their 
abilitys with more or less difficult speakers? Although the overall 
performance should be more than sufficient with 4/8 ohm speakers, i don't 
know about the effects of speakers who have very low resistance in 
lower frequencys (like the Infinity's). Anyone using the same amps?

Thanks for all the responses until now. Unfortunately most of the 
recommended speakers are too expensive or not available here (JBL L-5, 
Vandersteen, Definitive Technology, etc.) (Just don't stop with the
recommendations, i'm still looking =)

Thanks again,

About 5 years ago, there were some units available which were able to pick

reception.  I haven't seen one of these for several years.

There was a construction project for one of these boxes in Radio-Electronics
three or four years ago.  At the time, you could get a kit of parts,
including printed circuit board and at least the less common parts.
The circuit, which did general real stereo sound, did not claim to adhere
to the MTS standard for decoding the sound.

This information is contained within a normal two channel stereo audio
signal.  Assuming the decoder box adheres to the MTS standard, you should
be able to plug the outputs into your Dolby Surround Sound processor and go.

	I just posted an article asking for suggestions on good
portable disc players.  After flipping through Crutchfield's new
catalog I'm wondering if I shouldn't just buy a new stereo.  As you
may remember my home stereo consisted of a discman and AR's Powered
Partners.  One of the speakers buzzes a little and the bass response
is almost nonexistant.  If I got a new portable cd player I would want
one with a radio.  There don't seem to be too many offered this way.
	In Cruthfield I found the Yamaha YST-99CD, which seems to be
exactly what I want. But it has "flat" speakers.  A friend that has
Oslen(?) flats say that they sound terrible.  The Yamaha employs what
they call "Active Servo Technology" for bass response.  Does this
stereo sound good?  Has anyone had any experience with it or have any
opinions?   The list price is $429 and Crutchfield has it for $399.
I'm sure that I can find it for less but its still pushing my budget.
