I like the Arcam CD players.  The Alpha is good, and while the Delta is
a bit better I don't think it's enough better to be worth the extra
cost.  That's a matter of personal values, though, and you really
should try to hear both so you can decide for yourself.  For the amps,
though, I think Rotel is a better bet than Arcam -- though it IS close,
and they do have different 'features' which might influence your
choice.

First up, the input format to a Dolby Surround (passive logic) and Dolby
ProLogic decoder is the same. It's all Dolby Surround (for the home versions)
or Dolby Stereo (for the movies).

Obviously Dolby Labs sell such devices, but there are other manufacturers that
sell Dolby-compatible encoders. NBC use encoders made by Shure for example.

You first step is to contact Dolby Labs. When I asked them for tech info on
the system I also got some brochures on Dolby encoding. If you want to be able
to claim 'Dolby surround' you will probably have to pay for a Dolby consultant.

I have a pair of ~10 year old Bose 901 series III`s.  The speaker
surrounds has completely rotted out on seven of the eight drivers in the
back of one of them.

Look at the material used for surround the cones on the drivers.  The foam

I imagine that the cone could become "tired".  Drivers can be reconed
however.

	I am looking to buy a sat/sub combination and a friend
recommended M&K to me.   I have several questions on this and would
really appreciate any responses to any/all of the queries...

	1.  Could I hook up any M&K subwoofer to a pair of M&K 
satellites??  I know that in the case of the Bose AM5-II, you cant
do this.

	2.  I know the model of satellites I want but unfortunately
I dont know the model number (only know what it looks like) and I cant
find a local dealer who stocks M&K.  Could someone help me out with the
model number of the M&K satellites that look like...

	3.  What difference is there in sound quality if my amp. does not
have a subwoofer input?  I will be connecting the speakers the traditional
way -- satellites -> sub. -> amplifier.

They have some nicks and such on the cabinets, but are in good condition
otherwise.  One needs a woofer, it costs $50 for the part.

0dBu is the same as 0dBm except that with dBu there is no termination
resistor.

I expect that the DAT machine is "rated" for dBu and the source is
dBm?  If you want both devices to read 0Vu (in the case I have stated)
you will need to put a termination resistor on/in the DAt machine.

I am specifically NOT getting into a long discussion of the merits of
termination of lines etc because it doesn't seeme to relate to your
question.

Should you need further information I can supply it.

The sensitivity is 87 dB @ 1 W @ 1 m, according to CSW, which is about
average I think. I can't say that I think the midrange of my Ensemble II
sounds harsh, but it lacks a bit in "warmth" which could be a little dip
in the midbass where the satelittes crossover to the bass unit.  I don't
find it to be bothersome, though.

In my small room putting the Ensemble II bass unit in the corner sounded
too "heavy" for my taste.  I now have it against the back wall between the
satellites and away from the corners of the room.  It definitely sounds
tighter when it's out of the corner.  The Ensemble II's bass response
rolls off below 50 Hz whereas the Ensemble I is good to 40 Hz according to
some reviews I looked at.  So for an extra $100 you gain slightly deeper
(and maybe cleaner too) bass and the flexibility of having two bass units.
Of course, two bass units makes the whole system bulkier which might be
an issue in a small room.  For this reason, and the $100 difference, I
elected to buy the Ensemble II.  $400 well spent I think.

Summary: looking for ideas for "best" enclosure....

Organization: Purdue University Computing Center

I Have just purchased a pair of Dynaudio 21W-45 8.5" drivers.  I am 
looking to use them in an audio install for now and would like some
advice on the type of enclosure that this driver is best suited for.

I have to set a volume limit of 1.75 ft^3 in order to get it into the trunk.

I have designed (with perfect box 4.56) an isobarik enclosure of 1 ft^3.
It is ported (two ports, 1.5" dia and 9"+ long- forgot the exact length) and
has a -3dB point of 32Hz.  I realize that this allignment is less efficient, 
but it gave me the low bass extension that a more efficient allignment could
not.  The curve is almost flat with only a slight dip around 50Hz.  

Is this the best way to go?

Does anybody with experience with this driver have any other recomendations?

I would appriciate any input!

If the problem IS with the speakers I would suggest that you attack
the peak in the speakers.  It is common for speaker manufacturers to
do response compensation inside the speakers.

This method will eliminate the need to put the whole monitor signal
through additional electronics.

I would also test for your self the "strong peak at 3kHz" by listening
to a known source on known good sounding headphones and do a direct
comparison listening test.

Major acoustic treatment of the room will correct the speakers

room.

Go to used equipment brokers.  Look for a music/sound store that will
deal with you.

Parametrics can be a trap so be careful!  The details are involved and
are best learned by sitting down with one and working with it on a
project you can't *hurt*.

Hi, I was thinking of adding Dolby Pro-Logic to my stereo system and I would 
like to know what the best way of doing it is.  I currently own a Denon PMA 920
integrated amplifier which has very good sound and I'm very reluctant to change
it with a Surround Receiver.  The Denon has pre-in and main out connectors
to it.  The major draw back is that it does not have a remote control for the
volume which limits it's utility when used with the TV. I was thinking of
gettin a surround sound processor and I wanted to know how they are hooked up
to the amp.  I have seen that most of them offer a remote. Does this also 
control the front (main) speakers? If so, how?

Finally, if you think that adding a surround sound processor is a good idea,
do you have any suggestions as to brands and models? Preferably not more than
$300-$400.

Here here, bravo, etc.  I can not agree more.

I'd like to add that you should bring your own music with you and be willing
to spend several hours just to listen for differences in small items.  A good
shop will leave you alone, or even better, they shut-up and listen along with
you to get an education as well.  Another nice feature of this type of
critical listening is that the salesman BS mode switches off and/or you get
someone that knows their stuff listening with you and they don't try to
color your judgement with alot of talk.  When it comes time to discuss price,
they also give you a fair one as they know you know what most stuff can be
purchased for.  If your passion is music, the last thing they want to do is
turn you away from their store with alot of BS.
