	I find Led Zeppelin's _When the Levee Breaks_ to be a most violent 
song while driving. I find the need to bob one's head violently, stomping up 
and down on the gas, pound the steering wheel. The compulsion is ten times 
worse than in Bohemian Rhapsody. I remember one time, I found myself hitting 
the gas pedal so hard, I would floor it, completely release it, floor it... 
This was in my father's Broghm, and the constant jerking set the car in a 
violent rocking motion ( his car has the "not so nice" plush right, meaning 
the shocks are too bouncy ) I guess the rythm of the drum beats in the song 
was about the natural period for the shocks... Next thing I knew, the car's 
front shocks were bottoming out! This was going down I-295. The other 
drivers probably thought I was having a seizure. [ thank god I don't have 
the desire to pound the brake pedal....]
	As much as I love the song, I do NOT play it in the car anymore 
while driving.

I have had my Sony STR-AV1070 Receiver for a few months from now and
am pleased by it's performance.  But then again, I am no real audiophile,
so most stuff sounds good to me.

My question is in regards to the rear surround channels.  Now, I forget
what the specs are as in terms of rear output, it is something like
15 watts + 15 watts.

There are no RCA pre-outs on the back for the rear channels, just the center
channel.

Is it possible for me, in the future to be able to boost the rear channel
output by the way of an external amplifier?  How would this work with the
existing speaker outputs?

Any help would be appreciated.  Thanks in advance.

I agree that there seems to be a need for an audio group dedicated to
budget-limited audiophiles.  I don't think that people are looking for a
group dedicated to the el-cheapo garbage that is so prevalent in the
market, but rather the few products that actually perform very well and
are priced for the budget-conscious (such as the typical college
student).  Examples that occur to me would be the Panasonic SL-NP1A CD,
($150), the PSB Alpha's (~$200), used NYAL Moscode Amplifiers
(~$250-300), DIY Passive preamps (~$20-100), DIY RG-58 interconnects,
etc. etc.  I'm sure there are many people out there who have managed to 
put together very rewarding and musical systems on peanuts, and who are
 now either unwilling or intimidated to post their ideas/experiences/
comments on either of the rec.audio groups for fear of vicious flame-
responses.  The problem with, say a rec.audio.budget group, would be
rampant cross-posting, and even worse the resulting cross-flaming that
is inherent in related but unmoderated newsgroups.  It even shows up on 
rec.audio and sci.electronics from time to time!  Just my $.02..

 Next Monday I'd like to use my tuner - a Denon TU-260L - to record a programme
from Medium Wave (on 693 or 909 Khz, which have a wavelength of 330 and 433
metres) as well as I can onto my DAT recorder.

 Unfortunately, the little loop antennae supplied with my tuner picks up a lot
of whistles and whines, and leaves a lot to be desired.  Can anyone suggest a
way of improvising a decent medium wave antennae?  In particular, would
looping a very long length of thin enamelled copper wire around my room many
times have any effect?

I have a Philips CD-680X player on which I installed some of the popular
modifications done to the 16-bit Philips-based boxes.  The Philips players
had series resistors (typically 10 ohms) in the lines from the regulated
supplies to some of the integrated circuits.  These are marked as "safety 
resistors" in the schematic, and are likely fusable resistors to interrupt
current if a short develops (someone correct me if I'm wrong on that).

Since the resistors have the effect of reducing the stiffness of the 
power supply, modified Philips players often had these resistors removed
(e.g., replaced by a jumper). 

I cannot vouch specifically for the audible benefits of bypassing these
resistors, although the net result of all the mods I did was worthwhile.
The modified player had no problems with tracking, but I had bigtime problems
with static.  On two occasions, I had a static pop jump from my finger to
the front panel of the player, destroying the chip controlling the front-panel
numeric/status displays.  Philips stupidly placed this chip right behind
the plastic front panel, very close to the controls.  Perhaps the safety
resistors would have provided a bit of damping to the static discharge and
saved the chip - I'm not sure.  My current Sony player has the important
ICs wired directly to the regulators, and the PCBs are behind metal shielding.

It makes no sense to amplify the digital signal.

The only option I see is to eliminate the amp by makeing a high
power D/A converter that can drive the speakers directly.  I don't
know if this is feasable.  My guess is that it isn't - at least
not yet.  In all D/A converters, you get an analog signal that has
a lot of extra high frequency noise that must be filtered out.  If
you wanted a D/A converted that could put out 100 watts of power,
then the transistors would have to produce a analog signal with much
higer power - maybe 200 watts?  Then you have to have filter out
that extra 100 watts of power.  This might be why it makes more
sense to do the D/A conversion at a lower power and then only
amplify the "real" signal.

It might make sense to build the D/A converted into the amp, and have
it produce a higher power signal than normal to reduce the number
of stages required in the amp.

There might also be some possibility of building the D/A conversion
into the speaker.  For example, instead of producing a high power, very
accurate analog signal to drive the speaker, you might be able to build
a speaker with a feedback circuit that worked in the digital domain.
The position of the speaker cone (or the sound output from the cone)
could be measured, and digitized, and then the output current driving
the cone could be adjusted to make it match the digital input.  But this
of course requires building a high quality A/D converter into the
speaker - which would make it cost way to much to justify at this time.

Or you might be able to build a speaker with 16 drive coils.  Take the
16 bit digital output and drive each coil with a different amount of
power.  This way, half of the D/A conversion occurs in the mechanical
domain.  But this means the speaker is much more complex, and you
basically need 16 amps per speaker cone instead of one.  I don't see
how this could possibly be justified.  Maybe some variation of this
will be practical some day.

   Also you can watch your local high end audio dealers for
   close-out specials this time of year.  High end audio speakers
   and other "core" products don't tend to be used as holiday
   gifts.  And the new models are about to be available for dealers.

   Most will tend to try to salvage business to pay the rent as well
   as clear shelf space for new models about this time of year by
   marking down existing stock quite a bit.

Various reviewers have noted that despite the claim that the Rotel 955
CD player is just the Rotel 855 with a facelift, the Rotel 955 sounds
NOT as good as the old Rotel 855. Hi-Fi Choice compared the two boxes and
noticed that an extra 100 ohm resistor to chasis ground has been added to
the Rotel 955 and that if it was removed you get back the sound of the old
Rotel 855. I've opened up the box of the Rotel 955 and the extra 100 ohm
resistor to chasis ground is plainly visible and was going to remove it
when a good friend advised me not to. Aparently the old Rotel 855 had the
problem that because it was floating, static could build in the system
which could lead to mistracking and the extra 100 ohm resistor to chasis
ground was added to overcome this problem. Why then does the 955 sound
not as good as the 855? Ground loops?
On a related question, what can be done to improve the sound of the
Rotel 955. I've installed the Laser Illusions spatial filter (I don't
at this stage know what difference it makes as the unit came with it in
and I am going to find out how to remove it to see what difference it makes)
and am waiting on a Simply Physics isodrive. I'm open to other suggestions
than an external DAC as simple changes may make a nice difference and I
don't believe that I should spend a huge amount of money on digital at this
stage as it is changing fast (hence my initial emphasis on the transport).

Now that's one of the most interesting ideas I've heard in quite a

perhaps the purchase of 5 Minimus 7's and something like a Yamaha

The cost should be way under the cost of a typical total package
(perhaps $500 US) and the sound would be perfectly matched all around
with decent kick from the sub.  This might also be an excellent
alternative for those who don't want to make their A/V system their

Hi,

I have a question regarding the Bose AM-3 Series II satellite subwoofer
speakers. Is it ideally suited for a certain type of music ? My tastes
in music are primarily jazz and reggae. When I called Crutchfield for some advice regarding this, the salesperson told me categorically that with my music tastes,
I'd be better off getting more conventional (acoustical suspension) speakers, 
adding that the Bose AM-3 satellite/subwoofer speakers were more suited for
rock music. He recommended the Advent Legacy/Bose 4.2 series II instead.

The saleperson at the local audio store here (Circuit City) was adamant that 
this was not the case. I spent an hour listening to a wide variety of stuff
on the Bose Am-3's at the store, but I really could'nt figure out what was 
missing. Does anyone have any opinions on this ? For the same price ($400/-) the 
salesperson at Circuit City recommended the Harmon Kardon, HK 10 speakers. They
seemed to be as good, if not better to my non-discerning ears, when compared
to the Bose AM-3's, but I was a bit hesitant since I am not sure if HK makes
good speakers. What do you people think ?

I'd appreciate any feedback from you regarding these concerns.

Nope, sorry, you're right off the mark.  I listen to just about
every kind of music (except for things from Star Wars-- I just listen
to Holst and cut out the middle-man) and after extensive testing,
I find that rock music is the best for driving.

Namely, for long, contemplative drives, especially at night:
	"Wish You Were Here" by Pink Floyd
for scaring roadside woodland critters, whilest traveling at
excessively high speed:
	Led Zeppelin IV

Just my opinion-- but my opinions are right.

NEAR dunno what model - great comments from industry folkks

Spica SC-30 ($400)
Spica TC-50 ($550)
(both great values, with drawbacks.  Spica will send reviews
that cover both sides pretty well).
