	some time ago, i posted an query about the break-in time
for the rotel 955 CD player. i expressed concern about the ``ghastly''
sound out of the box.

	lets get the break-in time out of the way. the stereophile
review said a month, my dealer said a day or two, and a couple of
netters said a week or two. i AB'd the 955 to a magnavox 560
after 0, 60 and 120 hrs. the sound noticeably changed altho
i feel uncomfortable describing how. it was all improvement,however.
(of course, i mean hours playing CDs.)

	my ghastly sound complaint turns out to be unfounded.
its all my fault. it was a combination of several things;
the new sound wasn't the best, a bad reference recording
(that i didn't know was bad), and an interaction with my amp.
the recording problem was a peculiar kind of subtle vibrato
fuzzing on acoustic guitar; the 955 revealed it, the magnavox didn't.
(of course, after noticing it was there, i could just make it out
on the magnavox.)

	so, the reputation of the 955 remains unsullied. when you
get it, i would recommend for the first week or so leaving it on
playing a CD (repeat is useful here altho i also select shuffle
so the player won't get bored). and yes, the high frequencies are
rolled off; violins turn into violas. and after several hours
ABing the 955 to the 965 (at home), i conclude that violins
on teh 965 sound like violins but everything else (the midrange
and bass) is rolled off to an unsatisfactory degree.

		andrew

p.s. to anyone who still believes all CD players sound alike,
try AB'ing the 955 and 965.

I would like to get the opinions of the rec.audio and rec.video gang
on a new audio-video system I am possibly buying.  There are also
a couple of questions about it that I hope some of you can answer.

The system:
   Yamaha RX-V850 receiver
   Polk Audio RM 3000 with wall brackets
   Polk Audio CS-100 center channel speaker
   Polk Audio M3 studio monitors (rear effects speakers)
   Sony SLV-696HF VCR
   Sony KV-27EXR20 27" TV
   Sony SU-276 cabinet (to hold the tv and audio gear)

Questions:
   - The system price is $3150.  Reasonable?  I am planning to buy from
     a store, and I know that I could save some by buying some of this
     mail order. 

   - I can save $200 by eliminating the Polk rear effect speakers and 
     using some Minimus 7's that I have. Is there something special
     about the M3's that would make them better than general
     purpose bookshelf speakers?

   - Do I really need these $7/pair gold-plated banana connectors that
     the store recommends?  
     Is this just something that audio stores do to rip people off?
     The FAQ mentions these things, but gives no recommendations.  I
     want some good opiniated mail please.

   - Consumer Reports 1993 Buying Guide says that the Polk CS-100
     center-channel speaker, when placed atop the tv, 'caused moderate 
     sound-related disturbance in picture'.  Has anybody on the net 
     experienced this problem?

Mail please, I will summarize.

Thanks -

Can anyone tell me where I can get the plastic-lined paper
inner sleeves for 12-inch records (remember those black things)?
The sort of thing better-quality LP's used to come in.
Once upon a time Radio Shack used to carry them, but I haven't
seen them at any RS shop for two or three years now.  Also, there used
to be a mail-order ad in the "The Gramophone", but I see that's disap-
peared too.
Surely somebody must still make them, given the audio enthusiast
interest in certain types of LPs.
Any leads to a source would be most welcome.  Please reply by e-mail,
as I seldom have a chance to keep up-to-date in this newsgroup.

I was going to e-mail directly to the gentleman who restarted the "Best `phone?"
thread but as John has started the followups I'll just join right in.

I also own MDR-V6s but have a slightly different slant on them.  I can believe
Telarc uses then as a recording tool because that is why I bought them. (Now
if I just had copies of the rest of Telarc's equipment. :-}) ).  I tend to
think of the V6s as the JBL studio monintor of headphones.  Tons of detail
and punch, you are not going to miss a thing off that master tape or mic feed.
For general music listening many will find all the detail exciting, others
would feel it a bit unrelenting.  On the comfort issue they are ok (for me)
but the plastic covered ear pads squeek on my metal glasses frames when the
`phones move against them.  Another reason I selected them is that of the
over the ear, sound blocking types they fold up into the smallest size when
not in use.  Handy for taking along to locations or on trips.  Finally they
are quite efficient so, unlike my Beyers, my collection of Sony recorders
can drive them to adequate levels using the internal `phone amps.

For a smoother yet still quite detailed sound anyone considering phones in
this price range owes it to themselves to audition Sennheisers & Beyers.
If unlike the original poster you do not need to block outside sounds the
Grados are highly respected, personally I found them to be uncomfortable
on my ears.

Which brings me to the three most important points of selecting head phones:
1. Comfort
2. Comfort
3. Comfort.
It does not matter how good they sound if you can't stand to have them on
your head.

I have a reversed question.  I have a receiver with Dolby Surround. 
The output for the rear is 4 ohm, 2x10 W.  I am using a pair of 
10 W speakers 8 ohm for it, so far so good.  Is there any potential 
problems for doing this?

Another question:  The rear speakers I am using were designated as 
front speakers for a low end all-in-one Sanyo system (turntable, 
receiver and double deck ...).  Since I got the new system, I bought 
a pair of Boston HD10 as front speakers.  Is it important to match 
with a pair of more expensive ones for the rear, or this pair of Sanyo  
perform just as good?

Thanks.

I am experimenting with surrounds myself after having bought a new
ProLogic receiver (Denon ACR-2000).  I have looked into the ProLogic
theory and tried to wangle as much info as I could about THX from LucasFilm
(not very rewarding) and looking at THX speakers in stores.

The info points in the following general directions:

	A. the best surround effects are achieved when *ALL* speakers have similar
		sonic qualities, particularly frequency response
	B. surround speakers should set up a non-directional "ambience" effect
		that surround the listeners from the rear and/or side.

The easiest way to achieve A. is to use the same speakers all around.  This
is somewhat complicated by achieving B. as below...

Achieving B in THX is typically done by having each surround speaker
actually radiate the sound in opposite directions (front and back) out
of phase with each other.  The ear apparently has great trouble
locating the source of the sound when this is done.  Then populate the
side and/or rear of the listening area with as many of these as you can
(2 is typical; 1 alone actually works; fancy THX setups have more, like
4-8 pairs in big theaters).

Some home experiments proved out a few things.  I also have RS Minimum 7s
for the surrounds (a stop-gap measure for the moment).  Since the surround
channels are driven with the same signal, driving the two speakers with
the same signal, in phase with each other, results in easy location by the
ears of the source of the sound: from one speaker when you are closer to one,
and from the exact midpoint between them when you are equidistant between
them.  This is not the desired effect.

Placing the two speakers back-to-back at the center rear of the
listening area, pointing one right and one left, and wiring them out of
phase with each other results in an amazingly good "diffuse sound
field" (the ear can't locate the source).  This *is* the desired effect
and sounds great on well-mixed movies.

The drawback of only one set of surrounds out of phase is that the
intensity of the sound drops off as the inverse square of the distance
from them, of course, which makes setting the surround level
difficult.  Better is to have multiple sets so a more uniform sound
field is established.

I've not noticed a "break-in" period with the 955 or most
CD players.  However warm-up is critical in anything containing
a multi-bit DAC.  They are only linear once warmed up, and, like
any CD player, contain amplifiers that require a warm-up.  I find the
955 requires several hours, and I never turn it off.

Just a comment / question.  Did you find more??

Hi, I'm looking forsome help in choosing a good, versatile, powered

I've looked at so far are:
                            1. Velodyne F-1200  ~100 watts    $1095

I haven't done a lot of listening. WhatI need to know is :

                  1. How much power is enough? (everyone says Velodyne's

Summary: Radio Shack Quality


I also feel that the case against Radio Shack is overstated.  Radio Shack does not
build many of their products.  Their headphones are mostly Koss.  They market
Aiwa walkman's.   Some of their products are made by CASIO.  There are cases where
there products are good values.  

The Minimus 7 speakers are great little speakers.  Once a year, Radio Shack puts 
them on sale.  

I have had better luck with Radio Shack telephones than any other brand.  Usually,
any phone I buy goes bad in a couple of weeks.  I now buy all of my telephones from
Radio Shack.  

Radio Shack also is pretty good about taking things back that don't work.  I have
had to take back a few items from time-to-time.  I got them replaced with no
problems.                  

I will never buy a CAMCORDER, TV or VCR from Radio Shack.  I will also never buy
any stereo equipment.  However, I would not avoid every product and I continue to
watch the flyers for some of their promotions.

    A simple electronic timer will do this.  The electro-mechanical
    ones come with accuracy of 1 hour down to 15 minutes.  The
    electronic ones can be accurate to within seconds.  All they are
    is a device which controls the AC power to the receiver.  You
    preselect the station, set the volume, plug the receiver into a
    simple timer (about $10 up to thousands), plug it into the wall,
    and snooze out.

Nah, not if you have the hardware in your PC to handle receiving over a one
gigbits per second and 16 bit 44.1kHz D/A conversion, and of course the drive
space to fit all that and fast enough software to make full use of it.
