Hi, I am an avid fan of Faure and Ravel, and was wondering if any of
the net audiophiles had recommendations on the different recordings
available of these composers. Specifically, I am looking for a recording
of Faure's Requiem, Pavane, and Pelleas and Melisandre. I have the London
label recording with Charles Dutoit conducting the Montreal Symph. Orch.,
Kiri Te Kenawa singing the Pie Jesu. This recording has all three pieces,
which is nice, but not necessary. I would like to find "audiophile" quality
recording, and a good performance. Please send mail to my address, or post to
the net, which ever is easiest.
					Thanks,

I'm not sure what you are asking regarding adding a parrallel output 
stage.  If you mean can you add two additional tubes as output tubes 
for push-pull parallel operation, I doubt it.  First, because when 
putting tubes in parallel, the output transformer impedence should be 
about half, and second, because going class A as you suggest you want 
to do, already will be putting too much current through the amp, both 
in the power supply, but likely also in the output transformer.

Unless you are completely redesigning the amp from the ground up, 
around your output transformer, I can't see that this way of taking 
the project would be a good idea.  I can see some reason to wire the 
EL34s in triode.

As you can tell, I'm skeptical also just about running the amp in 
class A, unless the transformers and power supply were designed for 
something very close to that.

Hope this helps.

Can't any clock jitter be got around by putting a ring buffer between the
bits coming in off the SPDIF line and the DAC?  When SPDIF reception starts,
the receiving equipment lets 32 or so bits accumulate in the buffer before it
starts clocking the bits out to the DAC using its own, crystal-controlled
clock.  If this were done, jitter of +/- one bit wouldn't matter.  The DAC will
see a steady, jitter-free flow of bits.

Well, I really don't feel like typing in the whole Radiotron
Designer's Handbook.  The best thing to do is hunt down a copy.  More
information than most people can ever absorb.  Unfortunately, they are
rare (used booksellers usually don't touch technical books), and when
you find a copy, it's pricey.  About 50 dollars is the going price
around here.

As for the getter (which makes the silver), that't not tantalum.  It's
something else.  (See Saga of tha Vacuum Tube for more detail on the
history of vacuum tube design.)  However, there aren't many books I've
found on the details of modern tube design.  (I've got one from the
30's.)  I suspect that may not have been an area of open research, and
was more trade secrets of the manufacturers.

Little chance of it being the speaker wire.  More probably a combination
of low speaker impedance and poor efficiency.  

If a speaker has an efficiency of 85db instead of 88db, it will take
twice the power to reach a given level of sound.  If the speakers have a
4 ohm impedance, the output transistors will dissipate about 1.8 times
as much heat as an 8 ohm one.  Thus, you may end up having to
dissipate 1.8 x 2 times as much heat for a given level of sound with the
Cambridges as you would have to with 88db speakers with 8 ohm voice
coils.  Small wonder your amp is hot.

Does the amplifier have a 4-8 ohm, 8-16 ohm switch?  If so, use the
low number.

Rob.......

I have a Nak ZX-9.  If you're unfamiliar, it was released about 2 months
priro to the Dragon and is really about the same deck as the Dragon sans
the automatic real-time alignment circuit and its related machinery.

The best tape I have found to date is TDK MA-XG.  Can't really tell you
if it is due to the better shell construction or the tape formulation itself,
but there isn't another tape on the market which sound s ANYWHERE near it.

One warning though.  MA-XG is expensive and hard to find.  The last
source I had for it charged something in the neighbourhood of $17 
apiece for C90s.

Good luck.  Let me know what you find out about your deck.  If you DO
try MA-XG, let me know what you think of it too.




Best,

I don't know about *must*; the energy required does not as far as I can
tell come from the tape, but from the relative motion of the tape and heads.
I don't have any official statistics, but tapes can be played hundreds
or thousands of times, and the limits seem more to do with physical wear
than "magnetic" wear in the signal itself.

Of course, magnetized heads can cause real trouble.

What do you think of Acoustat?  From what I've heard of the Spectra 33's,
they sound superb, far better than $10k Apogee's (and cost "only" $3k).

FYI, Acoustat are American-made electrostatic speakers featuring large
speaker area, and look like (but don't work at all like) Magnapan,
which seem to be more widely available in terms of large flat-panel speakers.

Also, has anyone ever heard some of those truly hi-end electrostatic
speakers that come on one-ton cast iron frames and cost $50k?  (So high
end they might as well be in orbit.  :-) ).  Sorry, forgot the manufacturer's
name.

Subjectively, to me Acoustat Spectra 33s can do one or two instruments
(solo voice, solo violin, solo piano) almost as good as a real instrument.
(And better than a real instrument in a bad concert hall.)  They reproduce
chamber pieces well.  Orchestral music, like any speaker I've heard, is
but a shadow of the real thing.

Probably titanium, which acts as an excellent getter and is often used in large
vacuum systems (i.e. several cubic feet) as a getter to absorb stray molecules
and bring the pressure down.

     Thanks to all who responded to my question about tube amps.  You are all
helping me learn about a subject that is sometimes quite confusing.  It is
people like you who help bring new people into this exciting (if somewhat ex-
pensive) hobby.  Thanks again.

New question:  How do all those solid state amplifiers that claim to use
new technology to sound like tube amps stand up to the real thing?For
example, most ads I see for Hafler and Carver say that they deliver tube sound
without the tubes.  Now I know that they can not be perfect because then there
would not be any demand for tube amps.  My question is, how close do they get?
As a Carver owner, I am interested to here tube owners/fans have to say.

As I mentioned during my D/A converter shootout, during my audition of a
Wadia X-32 I discovered that my Denon DCD-2560 did not provide a "Level 1"
digital output (meaning there was more than 200ppm of clock jitter in the
digital signal being sent to the Wadia).  This is important for Wadia
converters, as they program their gate arrays into what they call the
"Rock Lok" circuit, which is supposed to provide a 2500:1 further reduction
of jitter before the signal gets to the D/A circuitry.  If your transport does
not output a Level 1 signal, you must substitute an alternate EPROM which
essentially programs the gate arrays to act as a standard PLL (although they
claim that even in this configuration there is a 10:1 jitter reduction).

Well, I'm happy to say that thanks to some help from my dealer, Wadia and the
service manual for my 2560, (not to mention a source of high quality capacitors
of all places here in Longmont, CO and some time put in with my soldering iron)
my player now falls within Level 1 tolerances.  More importantly, I've been
told that the same basic modification can be made to any of the three "higher
end" -60 Denon units (1560, 2560 and 3560) to bring them up to spec, and that
units now leaving Denon spend extra time on the test bench making sure they're
up to Level 1 spec as well.

What did I gain sonically?  Better bass and improved soundstage depth and
precision.  What did it cost me?  $15 for the service manual and $.45 for
the parts.  If you have one of these Denon units and are pondering the
purchase of a Wadia converter, send me email and I'll relay what I did
so that if you're feeling adventurous you can do it too!  (If there's
sufficient interest I'll post the details here as well...)

As a general rule, IMHO, the more powerful the amplifier, the cleaner the
sound, all other things being equal.  The extra power provides a reserve
for those musical occasions which tend to overload less well-powered
amplifiers.  The extra watts aren't just there so you can blow away the
neighbors three doors down instead of just two doors down, they also give
more musical results.  Of course, better parts also helps...

Or even a new one for ~$400.  And you could probably get a discount on *that*,
so it's still cheaper than the Velodyne.  Plus, the Hsu goes down to 20Hz
@104dB *outdoors*, or 15Hz @109dB in a typical room (or something like that).
I don't know if the Velodyne can or not, I haven't checked it out.

I'd also like to point out that you *can* get a high pass crossover from Hsu.
They just assume most people wouldn't need it.  Plus, their subs are optimized
for low bass.

I've checked out the Hsu subs twice (the designer lives in Cerritos, where my 
parents live (and I live when not at school), so I've gone over to his home
and met his family and everything  :) ), and I think they're great (not biased
because I've met him, believe me).  I'd be hard pressed to find a sub for
under $1000 that can do as much.

And for all you Adcom owners out there (like me), you can get a good amp to
replace your Adcom for your main speakers, something not so hard in the
treble, and use the Adcom for what they're known for - bass!  :)
