Not clear.  Some large organs have the "principal" pitch
of the Great division at 16', although most are at 8'.

The above descriptions of the tone of the stops is
incorrect. Principal = open flue pipes, usually metal,
with a flute tone and added bright harmonics.  Bourdon =
stopped pipes, sometimes wood, sometimes metal, with a
mellow flute tone.

A quint stop plays an interval of a fifth (plus various
octaves) above the principal tone.

There can be quint stops in any division of the organ.  In
the above case the quint plays a tone two and a fifth
octaves above the 32' principal tone, which reinforces
the 5th (?) harmonic of the 32' stop.

The "Swell" name for a division specifically implies
that the pipes are enclosed in a case with movable
shutters that regulate the volume of the division,
causing the sound to "swell" when the shutters are
opened.  The "Choir" is a more general name for a division
that can be of several types and/or characters.

A Cymbel stop, also known as a Mixture, is a group of
several stops set at high pitches.  The roman numeral
denotes how many pipes play for each note.  Cymbels and
Mixtures can have pipes as little as 3/4" high!

  Unfortunately, not too many places sell them around here.  The place
  that had the Khorns had Martin Logans (I listened to the $2700 pair).
  They were very clear and I like their styling but they seemed very
  directional...he started off pointed both of them in a parallel

  then pointed them at me (letting the planes intersect) and I was

  however.  Granted these were less than a foot wide, but the widest
  ones were $7k...
  Any other suggestions?  I'm trying to find a Magnepan and Carver dealer

Subject:    Affordable parametric eq

    I now own a pair of AR M1's, and like them very well *except* for the
 strong peak at (I am told) 3Khz, which results in a pronounced sibilance ---
 "Well I miSSSSunderSSStood," sings Richard Thompson on his latest release,
  a CD which sounds perfect on other minimonitors. Also, a certain shrillness
  to things like cymbal at nice SPL's.
     Anyway, several solutions have been proposed by List members, none of
  which worked (but good ideas, all). Major acoustic treatment of the room
  *would* work --I know 'cause I tried it out at a high-end store this weekend.
  But it's not a current option because of the Partner Acceptance Factor (PAF).
     So, does anyone know of a *single* band, or at most two-band, *parametric*
   EQ that's affordable and very clean? The pro music dealers sell parametrics
   that begin at $500.00, but I was hoping more for the $300.00 range.
     Or, maybe I should just ask: ANY EXPERIENCES WITH PARAMETRICS AT ALL??
  I'd also be interested in semi-parametric EQ's and good 1/3-octave EQ's...
  Where are the bargains to be had?

     Your _last_ point is true.  However:

1.  The labeling inks reacted with the aluminum substrate on _audio_ CDs,

	theoretically only be applied to the solved-years-ago-ink-problem

2.  Laser discs had a problem years before (the sole referent of the misnomer

	together with a glue that reacted destructively with the poly-

3.  Microwaving a CD is NOT going to look the same as any kind of natural

This talk about high-end tables led me to realize that there is one brand
of high-end turntables (or, more accurately, source of high-end tables)
that I have heard, but never seen mentioned:

Has anyone heard the Merrill turntables, created/modified/etc by George 
Merrill (Underground Audio, Memphis)? I heard one on a system consisting
of a Merrill table, (I do not recall the preamp), Klimo amps on highs,
Dynaco ST-70 on mids and a modified Dyna 120 on bass into Dynaudio 
drivers. To me, the table did create a sound that was at least as 
clean as the high-end CD also in the system (Don't recall, but was sep.
transport snd D/a), with an effectively inaudible noise floor on some
new direct-disc records! It was just plain difficult to tell which
source was playing on many pieces! I know this was in near-sterile 
conditions, and the absence of surface noise would not last for long,
but it was an uncanny experience! 

Note: I am not making any comparison of the relative subjective
qualities of the table and CD. In fact, we did not even play the same
material on both. However, the overall absence of noise and distortion
on either source made them virtually indistinguishable w/o direct 
a-b comparison w/the same material. I have no idea how such an a-b
test would have fared.

Regards,
Gordon.

I have a pair of Polk Audio SDA-2B's.  I'm looking for a good amplifier for
them.  I have been told to steer away from amplifiers that warm the sound.
I'm looking for an amplier for less than $1500 and about 250-300 watts into
6 ohms.  My speakers will handle 350 RMS.

Thanks for the help.

Rick Waller
----------
I use Forte' 1A to drive my SDA-2B's. Forte' was designed by Nelson Pass 
and manufactured by Threshold. It is purge class A amp with rated power
50 W/ch. Before I purchased it, I compared it to a 200w/ch NAD amp( I
forgot model nubmer ), Forte' sounded much better. I paid $1100 for it( list
price ) 3 years ago. I think it is replaced by newer models now.

SDA-2B's are efficient speakers. Only half of volume dail can shake the
whole house. So, 50W/ch of class A power is enough for me.

I think that it is normal.  It is probably just the power transformer.  In
high power amplifiers the transformer is fairly large.  My receiver makes
the same type of noise when it is turned on.

   I would agree with the Telarc (and country), but the Kraftwerk
   and Pink Floyd stuff show off stereo separation more than imaging
   in my opinion.

   But my definition of imaging includes a decent illusion of 
   front/back location in addition to the traditional left-right
   location.  

   In other words, a recording and speakers with good imaging should
   allow you to notice that the violins are directly in front of the
   french horns (or wherever they are...).   

   These are speakers with extremely well controlled resonances,
   impulse responses, dispersion, and no early reflections.     

   You can get SOME sense of your speakers (and room) by playing
   test CD's with tone bursts and looking for smear much beyond
   a millisecond or two after the main impulse.  (scope the output
   of a good mike).  A LOT of grills cause smearing, that's why a
   lot of philes prefer the sound with the grill off.

		 Device Ground	
		-----------------
		|		|
		|		|
		-----------------
		  True Ground

Using the above illustration, if there is a connection from Device
Ground (say the chassis of a TV or amplifier) to the True Ground
(outlet ground or water pipe) in more than one place you form a
"Loop" through which current can pass in a circle.  If electromagnetic
radiation passes through the loop, current is generated in the loop.
It acts just like a radio antenna.  You can pick up TV stations,
radio stations, CBs and Hams.  The strongest source of local EMF
is often 60 cycle power lines.  That results in a 60 cycle tone (or
sometimes a 120 cycle harmonic) which sounds like "hum".  

It is pretty easy to avoid connecting one device to ground more than
once.  What is difficult to ferret out is when you have a string of
devices (as in an audio/video system) all connected together by
audio cables which are usually shielded and the shield is connected
to the ground on both ends.  Thus all the devices have their grounds
linked together.  If any two or more of the devices are connected to
ground, voila!, Ground Loop.  Grounds may exist in unexpected places:
A cable TV system has its shield side connected to ground near your
house for lightning protection, many devices have a connection to
ground through the ground pin of a 3 prong power plug.  You must
vigorously eradicate ALL ground connections and then try making one
and only ONE connection at different points until the hum or other
emf noise is minimized.  Sometimes hum elimination is an equal mix
of art and science. :-)
