I just recently bought an Onkyo Rx606. Lovely! I went to a high end store in
centerville, Va (DC suberbs). If you live in this area, I highly recommend this store. Its called Gifted Listener. I went
there to check out the Rotels. I mentioned to the dealer that I liked the idea
of a carousel and he mentioned that the onkyo was terrific. So he let me 
audition both of them. To my ears, the Onkyo sounded the same if not better
with certain musical selections. It was also $30 cheaper than the rotel. I bought it for $429. I saw it advertised at
Circuit City for $400. However, I would have never bought it from there 
because you could never get the personalized service that I got, at Circuit City.
 (I even get a free loaner while my player is being serviced, that is if I ever need servicing).

As I've said before, I have the same worries about a DAT deck in a car.  I 
know that they've been built but I wonder just how long they're going to last.
Anyone who has opened up a car cassette unit after it's been on the road a few
years knows what I'm talking about; even in car that's kept clean inside, 
the deck still accumulates LOTS of dust.  

Re a DAT deck, even if this doesn't bother the deck itself, having the 
rotating head contact the tape in a dusty environment can't be good for the
tape. 

Of course, if they could eliminate the tape loading door, that'd solve the
problem.  :-)

Magnepan does not inflate the list price for their speakers so you
will NEVER see them go one sale (at least I never have).  If you are
looking for a lower price purchase a dealer or used pair.  When I purchased
my IIIa's I did get the price down a little but don't hold your breath.

An excellent product including outstanding service.  I popped a tweeter a

speakers for any flaws and replaced the tweeter including the service
work free of charge.

I'll never go back to a box-type and I'm sold on Magnepan.  Now if I can

Buy a $50. walkman, then buy a pair of Sennheiser model PD-100 headphones
(about $50.) to go with it.  Not only will this combo sound better
than most $100. walkmans used with the cheap headphones they come with,

		       ^^^^

At least in the lower price range, I'd stay away from Aiwa.  First off, they
throw in both of those worthless features ("bass boost" or whatever plus
auto-reverse) on most of the models.  The tuner section is pretty poor (and is
particularly confused in radio-saturated areas like the bay area, as I learned
this summer), and the tape playback motor is terrible -- I've never heard so
much wow and flutter and overall incorrect speed.  Granted, I didn't expect
much for $50, but this is inexcusable.

Mine's not terribly well made, either, and doesn't give me any sort of
impression of durability.  I doubt that any mid-price Sony will be too hot
either, from my experience.

I know that you were referring to $100 models, and both Aiwa and Sony may be
quite good at that price range, but I just wanted to point out that this isn't
the case at lower prices (and I don't know of anyone who does make a decent $50
walkman, by the way).

>You don't need anything but play, fast forward/backward and volume (and

Dolby is probably a waste on a portable given its sensitivity to azimuth
alignment, which is too easily screwed up with all the jostling walkmans take.
If you play a lot of commercially produced cassettes, Dolby may be unavoidable,
but otherwise is probably more of a hassle than it's worth.  However, a
"metal/normal" playback equalization switch is a nice thing to have.

Unfortunately, as noted above, you'll have to do this altogether too often with
a portable.  (And it'll never be right if it's an auto-reverse model.)

I simply cannot believe that the ear, the most dynamic and

can be satisfied by 16 bits.
 
I don't think 16 bits can truly represent what our ears were

the difference between cd and md, but I CAN on a good system
with simultaneous a/b comparison.
 
I say lets leave it at ONE disc format for simplicity,

Best bang for the buck IMHO is VMPS subs.  They have a "smaller" one
with a 12" active and 12" passive drivers.  They have the original with
a 12" active and 15" passive and the "larger" with 12" and 15" actives
and 15" passive driver.  I have auditioned both the smaller and the original
sizes and they sound excellent if you want very good flat response into the
20Hz range for the original and about 30Hz range for smaller.  It is a tight
bass with no slop.  The smaller one lists for about $400 but you can mail
order it assembled for under $350.  You can order it unassembled for just under $300 and put it together yourself if that makes you happy.  I think they      
compete with subs much more their price but that is just me talking so take
it for what it is.

There are a couple of choices that come to mind.


Luxman makes a small 4 channel amp (F-110? I cannot remember the model) 
that is rated at 40w/ch, bridgeable, and is only about 1.5" tall.
Separate Volume controls on front panel for all 4 channels.
Since they resell the Lexicon CP-2 as their F-116 surround decoder,
it should work with all pre-amps.


Also, NAD does make a multi-channel box as well.
Look in the 9000 series.  9130?  
It doesn't have volume controls on the front.


Sigh, my Audio directory is not at work.
You might check a pawn shop or a used audio place and find a 4-ch
amp from the quad days ( 70's ).

   Dunno about the cheaper ones, but mine explicitly notes that the

   More likely to meet the cost constraints of smaller home A/V
   receivers which don't have the power supplies to drive a
   full-band center channel at full power...so they bandlimit to
   save a few bucks.  However it should be noted that most of the

   and rear channels just a couple years ago.

I have a pair of Infinity RS5000 speakers for sale.  The RS5000 have
an Emit K tweeter, a 4" midrange, and a 10" woofer.  The cone of the
midrange and woofer are made of some translucent polymer material.
On the rear of the cabinet are two controls.  One control for the
tweeter and the other control is for the midrange driver.  The cabinet
is 24" tall and has a beautiful oak finish.  

These speakers are in a perfect and umblemished condition.  They have
never been abused (i.e., driven to distortion).  I would describe their
sound as a warm deep bass, with clear crisp highs.

I am asking $400 or best offer.  Included are the oak stands they are
now on.

I tried writing you directly but it bounced back. The problem with your cd
player is tracking. I know this because I had 3 other cd players in the last
week go through the same problem and I fixed all three of them. What you have
to do is remove the cover and look at the circuit board. There will be a
"screwlike" device. You turn it just like a screw and it regulates the speed
at which the cd turns. Play the cd you want to listen to and turn the screw
till it finds the track and stops skipping. It may take a few tries but that's
all you need to do to fix the thing. Don't throw it out, get it serviced or
change any belts. If you still want to throw it out, send it to me and I will
take it! There shouldn't be anything seriously wrong with it.
             Hope this helps.

I own a Philips FC40 cassette deck that is a couple of years old now.  I am

and the Philips made superior recordings).  Anyways, I use TDK MA110 tapes.
I can get them for $7.00/3 tapes, which is only 33 cents more per tape
than the SA90's.  Some have told me that metal tapes are bad for the heads
and will ruin them in the long run.  Is this true?  If so, what is a GOOD
chrome tape that I should use instead?  Also, I'm just wondering if any of
you have used That's CD-IV or CD-MH tapes.  They are the best I've ever used.
What do you guys think?  (I like to make tapes from CD's for my car stereo and

You sceptics may learn by listening to music (not use it as background 
noise). Then you will notice that 'something is wrong' and you will perhaps 
change the amplifier or the speakers. When all you actually needed to do was 
to change your cheap NOK 10/m cables.

A friend of mine has very good results from the B+K preamp/amp combo,

Or, another good setup involved Rotels. Anything would good current
and smooth (not bright! ) treble should work well. IMHO, the 2ci's and

purchasing.
