Hello Netters,

I have a JVC receiver (2x100 W) for which I am looking for a
pair of speakers under $400. I heard the Bose 301 series III
bookshelf speakers and the Advent Legacy II. Could you please
suggest me any other good speakers in this price range?

e-mail you replies to vaidhyan@ecn.purdue.edu


Thank you.

You are wrong.  50 pound interconnects are rather like green pens for CDs. 
If you bought 40 pound interconnects you are smart, but 50 is gullible.

I agree! I would like to recommend the British speaker manufacturer
KEF to you. KEF speakers have a nice 'dry'/clean and neutral sound,
superb for acoustic music (and rock too, unless you want to
play very loud). Especially in combination with your Phillips
receiver they have the advantage of being pretty 'amplifier friendly'.

   Here I agree with Seth, so much emphasis is placed on what we can and can't

Or what you want to hear. That's one of the main weak points of most

Obviously you don't fulfill the requirements of maturity (just kidding). 
Some psychoacoustic parameters like the absolute hearing threshold have a great

Sound quality is relative to a reference. There's also the matter of price

This is incredible! 

What is this tax for? To cover 'lost royalties' as a result of 
home taping? If so, the record companies should allow manufacturers
to produce DAT (DCC or MNIN DISC) machines without SCMS protection.
As you know, the whole point of SCMS is to prevent people from 
copying from one digital tape to another, digitally, etc. So, how
can they justify this tax?

The interconnecting cable between components can make a difference. However
spending 60 pounds on a length of cable is being gullible. It is simply not worth
it. You can get much cheaper cable that will be technically better, then again you
may like the sound of truely awful cable that attenuates the high frequencies owing
to capacitance. Spend a tenner on the cable and put the other 50 into better
compunents (or 4 new CDs).

As for loudspeaker cable, again you can pay through the nose for rubbish like some
of the solid core cables that are thin, expensive and have some name printed on
them implying they eat suger puffs (only UK readers will understand this). What you
need in a speaker cable is low loss to all frequencies. Thick multi stranded
copper (silver if you can afford it!) helps here. 

Whatever speaker cable you  use, it will have a characteristic impedance nowhere
near 8 ohms, probably more like 100 ohms so there is going to be a missmatch
between the (hopefully) zero ohms output impedance of the amp and the 8 ohms (if
you are lucky) of the loudspeaker. As audio wavelengths are very long, this should
not matter very much even at 20 KHz assuming a good dampling factor at the amp. A
reasonably wide spacing, say 1-2 cm will recuce capacitance and boost HF
performance over a very close spacing. Don't spend more than a couple of pounds per
metre and buy it trade price.

60 pound interconnects are rather like green pens for CDs. Aimed at the gullible.

  I have a 1070 (bought nearly a year ago) that was doing similar things to
yours. The relay would click every so often, and only turning it off by remote
or changing the volume (also by remote) would 'unclick' it. I took it in to
a local authorized Sony repair center and just recently got it back. (Took 
about 2 weeks... :( ). According to the receipt, they ordered an IC from
Sony (hence the delay) and replaced it. So far, it still runs warm (it always
did), but there's been no clicking. More info. on request...

A half-step (in equal temprement) is equal to the 12th root of 2,
or about 5.95%.  So the tape deck can go nearly a whole step in

I do not know exactly what the mains power situation is in Sinapore so
I will make an assumption that it is similar to British power where
you have a hot lead (at 220VAC) an common lead and a (saftey) ground
(where used).

Your equipment is just two wire which I am assuming is common and hot.

If all the above it true than there is only one (well maybe more
but..) reason you have "hot" chassis's...A fault in the equipment,
leaky mains bypass caps, wiring error in "powerboards" or in the mains
connection that you plug into (let's see that was 4! reasons).

This hot chassis situation is very dangerous and you should be
extremely  careful. 

Does all of the electrical appliances you have have the same problem?

I would start unplugging equipment a piece at a time to look for one
or more that may have a fauly.  If you get to the end and the problem
is still there then plug each piece of equipment directly into the
mains connection bypassing the powerboards to see if it's that.

If all else fails *try* an electrician?

I didn't like the Ensembles at all. They produce a nice sound stage but they
are very bright and thin sounding. The bass is also pretty slim but this is to
be expected with speakers this small. To increase the bass and mid-range they
recommend that you place the speakers against the wall, but then the sound stage
goes to hell. To further increase the bass they say to put the woofers in the
corners, or - for even more bass - next to each other. I played some song
recital disks and the human voice comes across as being very nasal sounding. I
would expect a speaker of this size to get at least that right.

A local audio/video store is selling Mitsubishi M-S5376 speakers for 
a super discount of $300, claimed retail is $900.  They have a 12"
wolfer, 4" and 3" midranges, and a 1/2" tweeter.  They are very nice
looking speakers and as far as I know Mitsubishi audio stuff is good.
The salesperson said that the low prices were because they ordered a
huge shipment.  The store is Bryn Mar Stereo.

Does any have these speakers or know about them.  They sounded good to
me in the store, but does anyone know how well they last?  Is there
anything about this deal that I should know or beware of?

I currently have a nice Phillips receiver and CD player and a pair 
of cheap fisher speakers that I bought at a garage sale.  I wasn't
planning to get a decent pair of speakers until I got out of college
and didn't have to worry about something happening to them, but this
looks like a very good deal.

Any help would be appreciated.  The salesman said they would probably
have these for about a week at that price(until the shipment runs
out).

All the statements I've seen of the Nyquist theorem state that the
Nyquist rate is a *lower bound* sampling rate required to reconstruct
a bandlimited sampled signal w/o aliasing, for example:

	The sampling theorem says that x(t) can be reconstructed
	perfectly if the sampling rate f-sub-s = 1/T-sub-s is
	GREATER THAN TWICE THE FREQUENCY BOUND B for the signal.
	The minimal sampling rate 2B is called the Nyquist rate...

[emphasis mine. I would have preferred to quote a more commonly
known text such as Oppenheim&Schafer, but their statement has a
lot more math in it that I didn't want to try to type in on this
ASCII-only machine.]

Gedanken experiment: Suppose you sample a sinusoidal wave of frequency
2kHz (2k cycles per second, or 500 microsec/period) at 4kHz (every 250
microsec). If you just happen to catch the zero-crossings you would get
zero for every sample, which is not a very useful representation from
which to conclude that the reconstruction should be a sinusoid rather
than nothing.
