No mention of an additional board for the analogue section, given that
Alex isn't keen on capacitor coupling in the analogue output I'm
looking forward to hearing what other changes have been made.

Sean has posted a few times that the SB2/3's processor isn't fast enough

If I understand correctly, the Duet is basically a displayless SB3,

I have not been posting here long, but I like Sean's posts as well. 
Their 'no nonsense' approach is refreshing.  They are similar to
another engineer - Frank Alstine at AVA Hi Fi.  Careful reading of them
shows they are rather well considered.  My only concern is that when an
idea looks silly you should look at the guy making the claims.  Alex at
APL Hi Fi is a well respected engineer of quite a few years experience. 
If he makes a claim that looks on the surface like 'hooey' then perhaps
a request for clarification is warranted rather than dismissing it.

Thanks
Bill

Maybe, in effect, that's what APLHiFi are doing. Given that they're
stacking DAC chips and including a new single ended analogue output
stage (stated as disabling the XLR output), to me that reads like a new
DAC board being fed from the digital section of the original Transporter
PCB and bypassing the rest of the original circuitry. Pretty much the
same as Patrick Dixon is doing with the SB+, but based on a transporter
rather than an SB3. An expensive donor using the Transporter but his

Good point. I was only going to say that selling 27.6bit 212kHz
recordings does not make them worth buying.

OTOH (back to the subject), it would be nice to have a device able to
process all available formats like e.g. dCS Elgar Plus:

"This wide range of interfaces, combined with the unit's ability to
lock to any standard sample rate from 32kS/s to 192kS/s and accept DSD
data, enables the Elgar Plus to be used with almost any currently
available, or foreseeable standard audiophile digital source."

To understand why valves sound better in some ways than solid state,
and conversely.  Research in that direction has led some designers (eg
Hugh Dean at Aspen) to the design of a solid state amp that does not
have the 'colorations' of valves yet, to the ears of guys that like
valves, has their other desirable properties (musicality, fluidity and
the other gush they go on about).  Ask him what makes an amp sound good
(and he has designed a god awful lot of them) and he will tell you he
does not know.  There are tons of possible circuit topologies to
investigate and listen to. Me - I simply want an amp to disappear, but
since the ear is a rather complex thing designing an amp to do that
requires building and listening to it - not measuring distortion in a
lab or dismissing ideas that may on the surface look like hooey.

I appreciate Sean's comments as he is the designer, and engineer and
knows a heck of a lot more than I do!  Thanks for the voice of truth.

If Sean can look at the mod and know if it's going to be an improvement
or not from theory and design and reality, then thanks for letting us
know!

This takes personal preference and imagined improvement out and puts
objectivity in.

Parts swappers and modders are not necessarily right.  There is theory
and truth involved too.

A higher noise floor and the addition of some distortion related bloom
and color doesn't produce a better product unless that's what you're
looking for.

Nicely put, Radish.
The whole thing about mods (of anything) is that ultimately it is the
customer that has to decide if the mod was worth the money to them. The
OEM has zero interest in the outcome for the reasons stated. In this
respect, Sean's contribution to this thread is ... unusual.

I've recently had my DAC rebuilt (almost the only original components
are the DAC chip, PCB and case) and it sounds fantastic and way better
than before. I wouldn't expect the OEM to have an ounce of interest in
this. They built their original product - which I was happy to buy - to
a pricepoint and a technical/performance spec they set. Their job is
done. 
I wouldn't waste their time telling them how much better the mod is - I
know they made conscious design decisions and could have made it
differently if they had wanted to.

Sean (I think) is saying that he made the TP as well as he could at the
time - and if he was doing a TP mkII he MIGHT make some minor
changes...that is the nature of progress.
However, as the designer he is perfectly entitled - in fact he is more
entitled than anyone on the planet - to express an opinion on any mods
from a theoretical point of view.

Does anyone out really think that all manufacturers spend time
listening to competitor products? I don't believe they do. I think they
spend time following/refining their own vision.

For that matter, those who would like Sean to do the footwork in order

at the modders.

I don't follow that statement at all. It was an analogy. I am
_supposing_ that these bits of strings were sold by me, and then modded
and re-sold by someone else. Of course I am not actually in the bits of

Your analogy is a bit disingenuous - these mods are available, so you

You may have better things to do, but Slim Devices, a company producing
an audiophile product, should have someone who investigates actual
competing and complementary products.  This is not some theory out
there that the software version x has quantum alignment properties that
sweeten the sound, it's an actual product that someone makes and people
buy on the basis that it sounds better than yours.  How much time would
it really take?

I don't believe that the Modwright (or whatever) mods are better than
the stock TP; I haven't heard them, so I can hold no position. 
However, the more I see where you diss them without checking them out,
the more I am sceptical about the TP!

Would it not even be interesting to get the modders around and have
some kind of challenge?  Allow them to demonstrate the improvements,
with neutral observers?  This would be a fun event, and there's no
downside for you - every TP modded is a TP sold by you!

Maybe. Or maybe based on what I know of the Transporter and of
electrical engineering, I can be quite confident in my position with
just the information at hand.

Here's an analogy: Suppose I sell bits of string which are 3" in
length. Perfect for tying up very small parcels, attaching notes to
pigeons' legs, etc.

Then someone claims that by simply tying one of my bits of string into
a knot, he has increased its length to 4". Now, based on what I know of
string and of knots, I can safely say "no way".

Is the onus not on the tier of knots to demonstrate that he has in fact
increased the length of the string by his method? He could at least show
a picture of this magically knotted string so that we can see that at
least _something_ of interest has been done to it...

The length of a bit of string, like the amount of jitter in a clock
signal or the number of bits per sample supported by a digital audio
device, are observable things. But not only are they easily tested,
they can also be predicted and understood without even having to lay
hands on the thing, because we have theory to tell us how this stuff
works. 

However, nobody has seen, heard, or measured this claimed 4" bit of
string. Nobody can explain how one might tie a knot in such a way as to
make it 4" in length. Perhaps the first few people to buy such a string
will never take the time to hold a ruler against it and see how long it
really is. They will just be happy to have a longer bit of string
because they were told it is longer. That is exactly how these scams
work! People are gullible. The snake oil salesmen would be out of
business if people took time to test this stuff or learn how it works.

OK, more examples. 

Compare Georgy Cziffra playing Liszt with anybody else.

Compare Brandenburg Concertos played by Masaaki Suzuki and Ton Koopman
or Harnoncourt.

Compare any Russian music played by "Russians" (Russian speaking

Compare Strauss played by Reiner or Karajan with anybody else.

I'm not making any point here. Just listen and compare.

Of course, there are exceptions. E.g. Glenn Gould (Mozart, Bach, etc),

Re: [SlimDevices: Audiophiles] Doh! Now we need 24-bit/176.4kHz on the Transporter!

2008-01-08 Thread gharris999

And another thing...

I'm no Buddhist, but lately I have been trying to think through a
theory of what would constitute "mindful" listening.  This isn't easy
for me as I have trouble differentiating between "preference" and
"judgment".

When listening to music, I find that I have a hard time giving up
certain personal preferences: I prefer to listen to musical
performances that are contextually "in tune" and performed with good
ensemble (i.e. "together") and with some transparency of texture (i.e
so I can hear all the parts...I'm a "more is more" kind of guy) and
that also possessing of some hard-to-quantify "other" element, which,
for lack of a better term, I'll call "interpretation", and which, for
me, I think is really about "coherency".   My shorthand for this, and a
term seemingly laden with judgment, is a "good" performance.

So, given a "good" performance, isn't it my job, as a
struggling-to-be-mindful listener, to try and strip away all the rest
of my prejudices and expectations so as to bring "fresh ears" to the
performance?

And yet, isn't most western classical music all about the creation,
denial and ultimate fulfillment of expectation?  (E.g. Mozart "works"
for us because he is so clever at setting up multiple layers of "ahas!"
for us.)

To me, this poses something of a paradox.

2008-01-08 Thread gharris999

I don't think you've misunderstood this at all.  Yes, it's off topic,
but I'll gladly pay the OT fine.

EVERYBODY plays with a heavy musical accent (pun not intended.)  It's
call interpretation.  With the exception of truly iconoclastic
interpreters, interpretations tend to cluster together in groups of
minimal variation.  You could call them "dialects" or, less charitably,
"fads."  Its not surprising that this is so when you consider how
musical pedagogy has worked in the 19th & 20th centuries.  And again,
it's not surprising that there would be a nationalistic element to
this.

But do you have to be Hungarian to be able to REALLY play Bartok?  Or
French to be able to REALLY play Satie?  Of course not.  If you did,
then you'd have to be a, what -- 300 year old Lower Saxon to REALLY be
able to play Bach.

There is no REALLY right way, period.  And then there is taste.  And,
as we all know, there is no arguing with taste, or about taste, if you
prefer.

Early Music practitioners gave up on the term "authentic" many years
ago precisely because of this philosophic problem.  The term of art
these days is "Historically Informed Performance Practice" a.k.a. "HIP"
performances...no more claims of "authenticity".

I was in Budapest a few years ago and listened to a concert of baroque
music performed by some of Hungary's best young string players.  It was
totally like getting caught in a time warp:  they played like "modern"
western European and good American ensembles used to play baroque music
back in the 1960s: heavy vibrato, "terraced" dynamics,  minimal rubato,
no metric accent, etc.  Not a "HIP" performance in the least.  And yet
I found the performance totally enjoyable.

So, for me, the lesson is not only about the empathy and emotional
connection between the musician and the music, but also about the
empathy and emotional connection between the listener and the musician,
too.

I have never said any such thing, and you're absolutely right, that

What you may not know is that many of the ideas that went into
Transporter came from other experts in the community who educated _me_
about this science. Now that Transporter is out, the bar has been
raised much higher in terms of what needs to be done to take it a step
further. However, if you read the forums carefully you will find a few
posts where I have acknowledged several possible improvements worth
trying.

But hey, maybe I don't know my head from a hole in the wall if you

That is because it is not an RG-6 cable! How hard is that to figure

We have found that cables with copperweld somehow don't sound as well
as ones with pure copper. Even the ones with silver-plated copperweld.
Yes, there are times when you need something like RG-179 or -187 for
internal wiring. We cringe when we are forced into something like that.
(And it does happen.re: SB2/3 mods.)

When you don't have a choice, well, sometimes you have to do what you
don't want to. When you have a choice, there are literally 100s of
choices when it comes to 75 ohm cables that perform better.

Perhaps with a talented designer. But the usual RLC filter can't be as 
complex as a nice tube and big honking transformer.

Tube amps have been well understood since the 1930s. Its easy to get 
"tube sound" from a tube amp, you can get the same sound from a solid 
state design, but not as easily.

Sure, its 'possible' to make tubes sounds like transistors, and vice

state, get them.

Sean didn't say the Transporter is perfect and can't be improved upon.

He said it couldn't be done by merely adding components - it would take
a complete re-design of the PCB.

Please read more carefully.

I think the idea is to use something like a CS8421 and up-sample it to
32 bits, then feed it into AKM 32 bit dacs.  At a technical level I
have a preference for Anagram upsampling technology but I have an open
mind.

The ear is a rather funny thing.  You really need to suck it and see to
find out. Some guys, for example, claim they can hear jitter below 2ps. 
I find that hard to believe, but am willing to give them the benefit of
the doubt.  My greatest concern about such claims is if those that
claim it are willing to subject it to a blind listening test.  I
generally discount those that wimp out on doing it.

Thanks

First I want to make it clear I am not a tube fan.  To me it is fragile,
expensive, old tech, whose day is long past.  IMHO, equally good results
can be achieved with solid state at a cheaper price.

Tube gear can be designed to be as clean as solid state, and solid
state gear can be designed to sound like tubes.  Tubes are inherently
more linear than solid state, so require less negative feedback for the
same level of distortion.  Negative feedback, while improving
distortion, harms transient response.  Many audiophiles (I am not one
of them) prefer no feedback class A designs - tubes naturally lend
themselves to such designs.

And solid state isn't?  All components change a signal. Many in fact
believe (guys like Frank Alstine) that hybrid circuits can be designed
giving the best of both worlds.  His take is the linearity and higher
voltage of valves makes them great for input circuits, while the low
output impedance of solid state makes them great for output circuits
driving loads.  Personally, I believe fully solid state circuits can in
practice match valve, or valve hybrid circuits, - but technically he has
a point - I just believe it is not worth the effort.  Blind listening
tests conducted by National Semiconductor showed it was rather
difficult, (but probably not impossible), to beat a lm4562.  I have no
problem with guys attempting it - and yes if something sounds better is
a personnel preference.  Searching for the ultimate is what led National
to develop the lm4562, which in blind listening tests, by all reports,
usually does beat the previous workhorse - the 5534.

Sure - but more than a preference for the 'distortion' of valves is the
reason, otherwise we all would be listening to ultra low distortion amps
with massive amounts of feedback that sucked the life out of music.
