No, assuming that the supply cord to the strip is indeed heavy gauge (such that
there is no added drop due to the load - unlikely anyway, as most audio
systems really aren't that big a load compared to, sat, your typical space
heater :-)) and that it is properly grounded and provides grounding (three-
prong) outlets.  This might even be a slight improvement, as without the
strip you could be forced to use AC outlets which are on different branches,
and run into more serious noise problems as a result.  At least with the 
strip you know everybody's on a common ground.

First of all, I would seriously doubt he owns a Class B amp.  Most
home audio is at least Class AB.  You won't find consumer audio with a 
class B rating unless it is low quality car audio, or maybe a clock
radio.

Secondly, why shouldn't he put his amp on the top of his rack?  I
would say that is a very wise thing to do.  That's where I keep mine.
If you put it underneath the rest of your components, you are simply
cooking them as well.  Of course, if you have them in a sealed
(or even simply air-flow restricted) case, then yes, perhaps it would
tend to build up heat at the top.  However, by the nature of his
article, I do not believe this is the situation.

I've measured the temp of the air around the top of my amp, and I
have found it to hit highs of around 130 degrees F.  This worried
me slightly, so I keep a whisper fan running on it constantly.  With
the fan, it never hits above 80.  I don't know what a safe operating
limit is.  Try looking in the back of your owner's manual, where
they give the unit specifications.  Often, they will list temperature
and humidity ranges for ideal operation.

Subject: Subwoofer hookup advice requested
Organization: Texas Instruments
Date: Fri, 21 Aug 1992 19:59:08 GMT


I have a Velodyne (powered,adjustable crossover) subwoofer and I'm
trying to figure out the best way to hook it up given the following
constraints.

Amplifier is 15 feet from Subwoofer which is near speakers.

Amp 125wpc.
SW  100w.


The options are:

(1)
            line level
pre-amp out ---10 ft--->

            line level   subwoofer/crossover
            <--10 ft----

amp         speaker wire
            ---15-20 ft---> speakers


(2)
            speaker wire
amp         ---10 ft---> subwoofer/crossover ---5-10 ft---> speakers


The negatives for each as I see them are:

(1) Subwoofer and speakers are effectively 25-30 ft apart.
(1) pre-amp to amp is ~20ft.

(2) amp is works harder since it amplifies low frequencies.
(2) I would suspect that line level processing is better.

Is 35ft enough to cause phase problems?
Is 30ft of (shielded) line level, too much from pre-amp to amp?


Any comments (including "both stink" with suggestions) are welcome.


Thanks in advance,

My aging system is showing signs of wear.  I've been out of the audio
scene for a while and need some advice/help.

*  I have a Mission DAD 7000 CD player.  Beautiful unit, still love it,
   however, I am having problems with the output circuitry.  Does Mission
   still exist?  or am I going to have big problems (read bills) getting
   this thing worked on?

*  I also use a dbx 228 external type II NR unit with my Nak tape deck.  
   The panel switches are pretty worn.  Does dbx still make NR units, or
   do they just manufacture speakers for DAK?  ;-)
	
*  I never did purchase a tuner.  (Could never justify spending money to
   listen to commercials).  I could use some recommendations on a good
   value in a tuner.  My new cable company has half of the stations
   simulcast in stereo instead of using the stereo TV bands.  (Yeah, this
   is the 90's!)

*  Does Dynavector still exist?  I am curious due to my vinyl investment.

Thanks to all who reply!

Right. But this guy wanted a sub-woofer not surround-sound. 
And as his sub-woofer reject frequencies above 100 Hz, I'm not
sure that the result will be really great !

I heard them recently at Bay Area Audio with Conrad-Johnson electronics.
The width and depth of the stereo image were amazing good.  They had
beautiful, realistic-sounding bass.  I was so impressed that I bought
the electronics.  (I already had decent speakers, but I may still trade them
in for the Stratus Golds.)

However, I thought the speakers looked slightly klutzy.  Maybe the same
talented speaker designer also specified the appearance of the cabinet, 
about which he had somewhat less talent?

Watch out for Sound Advice.  Their prices are good and
they have quick service, but they lie like dogs when it comes
to expressing themselves as "authorised dealers".

Case in point:  I was interested in buying a BA subwoofer.
I called Sound Advice and got a real good price.  When I asked 
they claimed to be an "authorised dealer". 

A friend had heard that BA did not have any mail order
dealers, so I called BA up and asked
if they knew of Sound Advice and who were their Authorised Dealers
in Wisc.  The lady gave me a long list which DID NOT include Sound Advice.
She even remarked that I was not the first who had asked about Sound Advice.

I asked BA if they had a standard US warrany, and the lady said they would
back up their products.

I ordered from Sound Advice and received what I believe to be a
grey market device (French and English writing on Box).  The box 
was not double sealed and appeared to have been opened but not
appear to have had the subwoofer removed.

At first I was unhappy about the BA SW, and asked if I could return it.
Sound Advice gave me some BS over the phone and told me I should
have bought brand X like they had originally told me (or so he said).
He then said if I allowed anyone to return anything I could not sell them
for the prices I do.

I did some rearranging, and hoked the sub in differently. I have found a sort
of operating sweet spot amongst my system and now
the SW is working flawlessly and adds greatly to my home theatre,
but in the future I will be more cautious.

fyi,

mike

I talked to the home THX rep at Lucasfilm some months ago trying to find
out specific info so I could at least move in the direction of THX
quality without spending mega-$$.  Bottom line: Lucasfilm will not divulge
any of the specifications or guidelines unless you are a licensed THX
manufacturer.

From the very few generalities I did get, I would conclude that you
simply need reasonable-quality components (noise, distortion, dynamic
range are key, but none require exotic designs), and a lot of
experience setting up listening environments.  The speaker orientation
and placement, especially the surrounds, are critical.

I think that if they were to publish the specs and guidelines,
Lucasfilm's competitive advantage would disappear since they would
probably be fairly simple and straightforward to meet.  I don't believe
there's any magic involved; just collective experience within Lucasfilm.

Note that all the above is conjecture and opinion, but based on my
own experience with audio design I think it's generally true.

First I want to thank you all for your many helpful responses to my questions
about the NAD/Adcom/Magnepan system that I am about to purchase. (At the
time I asked my questions, I was seriously considering purchasing a similar
system.  Various suggestions from a number of you helpful souls allowed me
to put together a system which I thinks sounds even better and yet remains
within my budget.)  Allow me to update my intend-to-purchase list:

CD Player:  NAD 5440	   	$430
Amplifier:  Adcom GFA-555II	$850
Speakers :  Magnepan 2.6	$1675

I'll be plugging the CD directly into the amplifier.  It is variable-output
and so I can control the volume that way.  Given the dispute that was raging
hear about the necessity of a preamp, I decided to solve it for myself by
listening to the system with and without a preamp.  I heard no deterioration
of sound with its removal.  The money I saved allowed me to get the 555II
amp and the Magnepan 2.6 (versus the 545 and the 1.5s).  There was really no
doubt about which way I was going to go given that I didn't not think the sound
suffered without the preamp.  Again, if anyone missed my post last time around,
I'm interested in any input (experiences, impressions, cautions, etc.) on
any and all of the components above.  That is not my main point in writing
this time, however.  My main question concerns what sort of cable I should
use to connect the components/speakers and how much I should spend on
connectors.

I understand that there is a considerable amount of debate on whether or
not or how much connectors affect sound quality.  I don't want to really
rekindle a flame war, but am really looking for some advice about reasonable
cables at reasonable prices given the system I'm purchasing.  I am really
close to my absolute limit in terms of spending on this equipment, so
suggestions of $1000/m cable will unfortunately be of no help.  I'd love
any help you could give (suggestions of what would work for my system,
what works on your own system, what I absolutely *must* do/hear before I
think about buying cable, guidelines of how much to spend on connectors
for a $3000 system, whether it is reasonable to expect a discount on
cables from a store from which you are buying $3000 in equipment already),
again I stress *any* input would be helpful and most appreciated.  Thanks
for your time.

NNTP-Posting-Host: headcrash.berkeley.edu

Hi!  I have two questions about two different types of speakers.

First, looking through Stereophile's Recommended Components list from April,
I noticed that there was a speaker in the Class-B list which had a price
way out of line with the rest of the list ($2000/pair).  That was the PSB
Stratus Gold.  I'm curious what experience/knowledge any of you have with/
about them.  I am having some difficulty locating a dealer near me, and so
in the meantime I'm looking for opinions.

Second, I was looking through TAS's Guide to High-End Components (lustful
spec-monger that I am ;-) and I saw the most extraordinary specifications
listed under a Metaxas Audio Systems (MAS) speaker called Revelation.  Here
are some of the more extraordinary ones:

Frequency Response 15 Hz - 150 KHz
3 Drivers
Driver size 36" x 100"
Sensitivity 102 dB
Distortion .005 %

I was wondering what these babies sounded like.  If these specs reflect the
range of *quality* sound produced (i.e., if this sound is musically satisfying),
then these speakers could be easily worth the price listed of $4500.  Of
course, I'm looking for anything you might know/have heard about these or
where I might audition them in the Bay Area.  They sound fascinating on
paper, I'd love to hear what they sound like in the room.

Thanks very much for any help.
