	I have this problem with the electrical noise in my dorm room.
(I think).  The power lines in the room don't seem to be "clean".
I have a Nakamichi TA-2A receiver hooked up to Celestion SL-6si
speakers.  When ever I, say, turn on my room light (flourescent), the
time in which it takes the light to turn fully on causes a popping
noise out of my speakers (when the receiver is on, that is).

Likewise, I get a big pop when I turn my CD player on as well (which is 
located next to it.)  The fridge, Also does this too, whenever the
condensor kicks in.  The CD player is connected to the same power strip,
but the Fridge isn't. 
The Thing is, my Computer doesn't do this to my speakers, and neither 
does my tape deck (a/d/s/ C4), which is also located next to the receiver.

This happened in someone elses room, so I brought the receiver to be
serviced.  A couple weeks later, it came back to me with a note from
the technician that he had benchtested the thing for 1 week straight and
couldn't replicate the symptoms (thank god it was under warrantee).

So, I'm assuming that this popping noise in the speakers is a problem with
the electrical lines around here.  Is there some way that I could fix this?
Would something like Adcom's ACE-515 help? [not sure abou tthe part  #]

And why doesn't the tape deck affect this? could it be magnetically shielded
inside?  Oh, the CD player always kills FM reception when it's turned on...

Any suggestions would be greatly appreciated.

What about the electrical contacts of both the cart and the playback unit.

	I own a pair of Beyer Dynamic DT-990. When I auditioned different
pairs of headphones and decided on the DT-990, no other model came close!
The stereo-image, overall tonal balance and comfort make the Beyer a great
buy for the price... I tried Audio-Technica, AKG & Sennheiser models but
these where pale in comparison. Weither the DT-990 Pro has a removable
cord, I don't know. However, the cord on my Beyer can expand to about 8"
without any noticable pull. In my honest opinion, the DT-990 could just be
the *best* pair of electro-dynamic headphones in that price range.

Talking about watts per channel....
I'm looking at getting a new receiver (probably one of them new A/V Pro
Logic ones) and one of the salesguy told me that for the type of music I
listen to, instrumentals and classical, clipping is of an issue hence I
shouldn't get any receiver with less than 100 w/ch for the front
channels at least. I was looking at getting a "no so expensive" unit
with maybe up to 80 w/ch up front, maybe even down to 70 w would do?
What do you all think about clipping? 

I was also looking at the above mentioned Sony but if it's only 75 w
up front... and clipping is an issue, I might have to rule this one
out.

Thanks in advance.

Thomas.

Ho, ho, ho.  Love that nerd humor.

Among those I know who feel the need to own a subwoofer, Velodyne seems to come
highly recommended.  Unfortunately, none of these acquaintances understands the
concept of "subtlety," preferring to "show off" the bass capabilities of their
systems, much to the chagrin of those present.

I can't help you with prices, but surely one of the year-end audio catalogs
will, while in most respects useless, at least list retail prices for a variety
of products.

I purchased a pair of BUF-03s from Newark Electronics, who has
distributors all over the country.  I believe I paid about $25 for a pair
of EJ spec'ed but they also sell a few different versions.

I recommend you get their catalog even if you don't buy it from them.

Sorry, don't have their number with me right now.  Try your Yellow pages.

Incidentally, I'm using them as output buffers for a DAC I'm building. 
It'll also allow analog inputs to be sent straight through the pot/buffer.

The DAC uses Crystal's CS8412, NPC's SM5813, BurrBrown's PCM63P, Analog
Devices AD811 for IV conversion,  passive deemphasis, and a GIC output
filter using BurrBrown OPA2604 dual FET input opamps.  Haven't built it
yet but I've drawn up a schematic.

Since MD and DCC are brand-spanking new formats, they cost alot.  Theyll come
down in price... Proabably halve the price in 12-18 months.

MD is the best of both worlds.  I can record my freinds CDs, I can have
direct, instant access to any track, I never have to rewind, and the thing
wont skip (which Is really annoying with my discman, it skips all the time
when Im walking or riding my bike.. more annoying than rewinding).

Gad, you must be impatient!  Many DAT machines (some of mine included)
rewind at about 200 times the play speed.  It only takes a few seconds
to rewind the full length of a normal pop recording.  When you add the
ID numbering, skip, and track access features, it's really not too awful
to deal with -- not at all in the same league as an analog cassette.

By the way, I too am fairly excited about the MD as a portable format,
though I'm not happy about the compression concept.  DATs are great in
the home, studio, and doing field recording, but if you look at all the
teeny-tiny parts in, say, my Casio DA-R100, the thought of lugging it
to the beach becomes rather scary, especially when those parts are all
whirling around *touching* (yech) your favorite recording!

Happy listening,

Tony

As i mentioned in the post "questions on pre-amps", i mostly use 
the Rotel for headphone listening, both because i don't want to be 
bothered and my speakers are not great ones. But because the Rotel 
doesn't have a headphone out, i use the headphone jack of my Sherwood
receiver. i recently realized that i am not getting the real sound of
the Rotel through the Sherwood's headphone jack. So I either upgrade 
my system around the Rotel OR let the ROTEL go and get a reasonable CD
player which has a good headphone output, better than that of Sherwood 
of course. I've decided NOT to go the former. Have to resist it! 

  I'll let the ROTEL go if i get a reasonable offer. I guess i could
ask $260, right? But i'll seriously consider offers around $240. Bought
around August 1991.  Still under 5 year Warranty. With the original 
package. i'll take care of shipping.

  Also, i would appreciate any suggestions on CD players around
$300. Remember i use the headphone output very often.

Thanks!

I tried responding directly to Mike, but e-mail bounced.

Hi Mike,

There are hybrid designs that combine the best of both worlds.  They are
not easy to manufacture, but they cost less than full ribbons.  Carver
Platinum Mk IV is good example of a speaker that uses ribbons for mid
range and treble, but four 12" cone woofers (per speaker) for bass.
Unfortunately, because of Bob Carver's dispute with Stereophile and
Absolute Sound, these magazines no longer carry ads for Carver equipment
and refuse to review it.  This top of the line Carver speaker can be
bought for about $2500.  There is also a smaller and cheaper model.

Martin Logan makes hybrids as well but they are more costly.  Apogee
makes Centaur Minor, Centaur, and Centaur Major as their hybrids.  I
think Minors are under $1500.  You may want to check this hybrid
alternative (however, I'd bet many people would oppose the idea).

The problem with planar speakers (a friend of mine has Maggies 2.6R) is
that they are a pain to position properly and you pretty much spend the
rest of your life moving them as well as furniture around your room.
The other more troublesome issue is that ribbons are very delicate and
do not last a long time.  They also degrade sonically with time.  My
friend bought a 1-year-old demo pair from a dealer and after about 3
months one of the ribbon panels died.  He called the dealer and sure
enough since the speakers were under warranty the ribbon was replaced
free of charge (came really neatly packaged).  But then (get this!) my
friend realized just how lousy the corresponding panel on the other
speaker was.  By setting the sound to mono and switching between the 
two speakers it became painfully obvious that the old ribbon was dark 
and muffled.  He took the cloth off and looking from the side noticed
that the ribbon (which is BTW unbelieavably thin) has a couple of
ridged areas almost like wrinkles, unlike the new ribbon that was
perfectly flat.  So he called the dealer to come take a look at that
and dealer said he'd call Magnepan and get another replacement panel.

Problems with planar speakers are accelerated in humid regions where
they tend to degrade rather rapidly.  Regarding their suitability for
low frequency reproduction, I would agree with your statement.  However,
if you listen to rock music, there is something else to consider: how
dynamic the speakers are and by that I mean can they deliver punch and
slam.  Yes, you can play them loud but they just do not rock.  There is
always the feeling of some restraint.  I have listened to Quad ESL-63
for quite a bit and they are excellent, excellent speakers.  Beautiful
classical music coming out of them.  However, if I played some Rolling
Stones, ZZ Top, Led Zeppelin etc. they just did not sound right.  This
has nothing to do with reproducing low bass (say, 45 Hz) because such
low frequencies are seldom encountered in rock music (bass guitar will
go down to 40Hz and ESL-63 can definitely handle 40Hz).

Subject: SUMMARY: A/V Pro-Logic receiver: Onkyo or Technics ?
Date: 21 Dec 92 00:38:03 GMT
Organization: Viewlogic Systems, Inc., Marlboro, MA


Hi all,

This is the summary of the responses I received as a result of my
posting few weeks ago. I was trying to choose A/V Pro-Logic receiver and
it came down to Onkyo TX-SV70PRO and Technics SA-GX910.

First let me thank everyone who took time to respond. I got many
valuable suggestions and comments and only one flame (pretty mild and it
was useful too).

1. Overall quality.

Most people felt that Onkyo makes much better receiver than Technics in
general. I got many more responses from Onkyo owners than from Technics
owners, but they all have been very positive, both regarding sound
quality and reliability. No horror stories about either model. One point
was that SA-GX910 was top of the line for Technics, whereas TX-SV70PRO
is middle of the line for Onkyo (at basically the same price).

2. Importance of S-Video inputs (Technics has them, Onkyo doesn't).

Most respondents agreed that it doesn't matter very much because there
are not that many S-Video sources. Some pointed out that it makes a
difference if you make your own video recordings on S-Video camcorder.
But even then you need S-VHS VCR and TV with S-Video input.

3. Importance of digital in/outs (Technics has them, Onkyo doesn't).

I got very little response to this question. It seems that for digital
recordings (say from CD to DAT) it doesn't matter that much because you
can connect them directly (assuming they both have digital connectors,
otherwise it's a moot point anyway). I am not sure what else you can do
with this capability. One respondent suggested that it could be very
useful if the receiver was capable of re-clocking the signal to
different clock rate (say from 44.1KHz to 48KHz). I don't know if
Technics does that but I think not.

4. Power

>    SA-GX910 is more powerful (370W vs. 315W) but TX-SV70PRO's
>    power is better distributed, with the center channel the same as
>    front channels.

As it was mentioned many times in this group, almost all respondents
said that center channel power equal to front channels is very important
for Pro-Logic. Onkyo was recommended despite having lower power rating.

5. Class A amp ?

>    The spec for SA-GX910 says that this is Class A amp. What does
>    it mean ?  Is it important ?

This question led to a separate thread in this newsgroup, so I won't add
anything. Let's just say that nobody believed that Technics is a true
Class A amplifier.

That's all folks. Thanks again and Merry Christmas!
