Another question altogether, and quite right as well.
I hoep I didn't scare you off a new amp, just wanted
to scare off your scare (does that make sense?  It does???)

There are many fine moderate power amplifiers out there,
and the 2Cs are very easy loads (like 6.8 ohms minimum
20-20kHz ... I mean EASY).  But they are NOT particularly
"efficient" in terms of dBs out per volt in (the heavy metal
metric is earbleeds / k-joule/sec).

So if you plan to keep it under 95 dB (at 1 meter) or so,
100W will do you fine.

I've got a really nice 100W used amp for sale, if you're
interested, e-mail me off net.

My Sony 1020 (older model of yours) did the same thing frequently at
high volume (over 6) with a set of sub-sat speakers that showed the
receiver a ohm impedance.  This only happened with those speakers, and
since they have been replaced with a set of Dahlquist M-903's the amp
has never complained - even to higher volumes.  I suspect that the low
impedance is the problem (lame though isn't it).  I found that if I
ventilated the amp when using it with the old 6 ohm speakers, I could
keep the protector thing from clicking in.  Try a fan and see if that
helps dissipate the excess heat.  (I believe that the amp is shutting
down from overheating caused by excess power output to the 6 ohm
speakers.)  There probably is a way to adjust the impedance that the
amp is seeing, but I'm not sure how off hand.  
	Anyone care to explain if this is possible?

Try the Sony STR-D590, the Kenwood KR-V6040, or the Pioneer VSX-401.  They
meet your requirements for 2 tape monitors.  I love JVC video equipment, but
not their audio equipment (cant stand their recievers).

----------

No, there THEY go.  You spent $12 on nothing, since it
broke while under SONY's warranty, and not under the
purchased one.  You would have been given a new one
even without the extended warranty, since it died 
before the extended warranty went into effect.

If they claim that the extended warranty started on 
the original purchase date, they are devious scum, 
and don't deserve your future business.  If they are
somehow selling SONY equipment with less than a year
of mfg. warranty, the same opinion holds (unless SONY
doesn't normally include it, in which case SONY is
the scum, and I am ranting about nothing).

You should at the very least insist that the extended
warranty you already purchased now cover the new Walkman 
(starting when IT is a year old).  If they can't transfer
it, demand your money back on the warranty (it WAS unused) 
and buy another one if you are so inclined.

   Used Klipschhorns.  For pipe organ you need lotsa bass, dynamic
   range, etc.  I can't imagine a pair of 600 speakers that are
   gonna sound much like a pipe organ.  And IMHO only the
   Klipshhorns wouldn't need a subwoofer as well.

My turn to throw some more petrol on the fire...

People who've tried to explain why cables make/don't make a difference to the
sound of a hifi have concentrated on capacitance, inductance etc. I have 
another suggestion. If you don't agree with me, please mail/post a reasoned
explanation as to why I am wrong.

I know that a rusty piece of metal near a transmitting aerial can cause
interference to nearby receivers. This happens because the rust acts like a
semiconductor diode causing non-linearities that produce harmonics. If a
length of cable carrying an audio signal contains impurities then maybe it
effectively contains diodes that may cause distortion. Presumably, the
manufacturers believe that oxygen free copper and crystalline structures
avoid these effects.

I'm looking for a source for a couple of low-fi (el-cheapo) cassett
decks that have a timer (an amfm radio would be a plus) so I can 
set them to tape radio shows (like Larry King).  Obviously the
specs need to be minimal as I'm recouring voice only.  Auto Reverse
would be a requirement (so I can tape 90-120mins at a whack).

It's funny that VCRs do this all the time, but not cassett decks.

Has anyone else wanted to do this?  Do you have one that you want to sell?

Thanks,
Lance

   Contact DAK in North Hollywood CA.  They carry close-out specials

I think this is an unjustified attack.  Dick's article is not
arrogant because he does not use overt insults, does not cast
aspersions on the ability or intelligence of David Wright, and does
not state his own case as fact.  Mr Pierce certainly contradicts
Mr Wright on many points of subjective opinion, using direct, rather
brusque language, but emphasizes that his contradictions are his
own opinion or experience, not undisputed truth.  Mr Pierce may be
guilty of using aggressive language, but I think Mr O'Connor's
(badly spelt) assertion is unwarranted:

>  Reply's like

In my opinion, Mr Pierce has repeatedly demonstrated his experience
and competence in the field of audio engineering, and writes clear,
informative articles.  His reply to Mr Wright expresses many of
the frustrations I felt when I first read Mr Wright's article.
The following segment hardly sounds like discouraging open-ended
discussion:

A trifle facetious, perhaps, but Mr Wright's original questions
were not going to stimulate useful discussion because they started
from poor premises.

	On a related note, as this is similar to a JBL sub box I've used in 
live applications, can anyone also explain th modelling of a box like
the one below?  There are actually 3 ports in the centre chamber, one
which is a tube, and two open hole type ports. 
I have heard this box called both a triple chamber bandpass, by JBL, and
also a serial bass port enclosure.

        |         |         |          |
        |------------------------------|

	Could the boxes be modeled individually, or would you need to relate the
behaviour of each compartment to the box as a whole. Also, I've seen similar
designs where there were also ports from the centre chamber to each of the 
outside ones. How would this change the modelling?

The 7se is a great speaker for the money. You might want to check about
'seconds' - Paradigm periodically sells off new speakers with slight
imperfections in the cabinet etc. (I have never been able to see what
the imperfection was) and a reduced price. Often if you mention to
the salesman that you'll wait until the seconds become available they
will give you a pair at that price.

I own a set of BP10s as part of a 'Definitive' surround sound setup [I
also have a C1 center channel speaker and BP2 rear channel speakers, and
a Velodyne subwoofer]  The manual is correct.  These speakers definitely
need to be 'broken in' and once you've done that, you'll notice a
smoother midrange response.  I have.

I've very pleased with the overall quality of the speakers.  I bought
them locally and I haven't dealt with the manufacturer.  If you're happy
with the bipolar nature of the BP10s [and the BP2s], go for it!  These
speakers continue to amaze me with their realism.

The $110 applies to an 11 tube console w/ record player  with a complete model
nuber of 1210PLM.  I thought the radio in question was a large table top versio
n.  I've never seen either version of this radio, but $110 for a 1948 sure seem
s high, and I mean higher than the usual to high quoted in these guides. Was t
he Rolls Royce slogan from SC or a personnal comment?  Scott used Stratavarious
 as their comparative slogan.
And Aaron, this may be a dumb question, but are you aware of the swap meet i
n Elgin?  They had over 300 sellers and over 800 quests from 39 states & 5 coun
tries!
   The Bunis book is a fine refrence, but like most price guides, it's question
able.  I have both 1st & 2nd editions.  The first thing that caught my eye in t
he 2nd book was how he upped the prices on ALL bakelites.  He pretty much took
the 1040's sets which were mostly valued @ approx $30  in the first book and in
creased them all to $45.  Maybe I'm doing something wrong but I still pick up
non-playing sets for $5 at our meets.  The typical set as described goes for ar
ound $25.  The book is still probably the best for identifying year and descrip
tion.  I use the prices as a relative gauge.  And of course, I love looking at
the pictures!  Spencer Doggett
