2006-03-17 Thread julian2002

i'm of the opinion that whilst jitter and digital domain signal
transmission are important, once you get jitter under 200ps then you
effectively have that sorted and you start to hit the 'diminishing
returns' wall. of far more importance is the nature of the digital
filters and analogue output stage. of course as an audiophile i have
nothing objective to back this opinion up with just the observation
that those cd players / dacs that pay a lot of attention to digital
filtering and the analogue output stage seem to sound better (to my
ears) than those that don;t (i'm talking multiple power regulation,
massive power transformers, funky 'audiophile' components, etc.) even
if the 2 players compared use the same transport mechanisms and dac
chips - which to be honest below a certain price most do (phillips
transport and burr brown or crystal dacs)of course i'm also of the
opinion that 1 bit dacs and delta sigma decoding are the work of
beelzebub so what do i know...

PS,

In case anyone is interested:

Robert Greene, among others, has reviewed the Harbeth M40 in glowing
terms.  Is it one of the best speakers out there?  Yes.  Is it the
best?  No, of course not, because now we get into questions of taste,
room, needs, etc.  A Dali Megaline, which is arguably amongst the very,
very best -- it is scary good -- would not work in a 12x12 room.

However, I have owned speakers ranging from Dali (the Grands), Von
Schweikerts, Spendor, Quad ESL-988 and 989s.  For my needs and tastes,
the Harbeth is easily the more engaging, tonally pure speaker.  Quads
image better, of course, if set up properly and if you sit in just the
right spot.  Harbeths are easier to position and have a warmth and
rightness to the midrange that beat the Quads.  Apples, oranges.

So, this is what I find bizarre about Dan's comments: first, we have no
idea what he uses; second, if someone OTHER than Dan recommends a
component, it must, perforce, be a bad component and the user must be a
dupe.  

Of course, Dan, who hasn't been reviewing speakers on a weekly basis
for twenty years, who has no formal training in acoustics, no PhD in
mathematics, who is not a recorded musician and engineer for
well-received classical recordings, etc., certainly knows better.

Again, I just fail -- utterly -- to understand people who insist on
baiting and insulting strangers.  When that person has no legs on stand
on other than his sarcasm, snootiness, and financial agenda, well, it is
even worse.

[SlimDevices: Audiophiles] Re: SB-3 and external DAC

2006-03-17 Thread CarlOtto

Hi!

Well, I'm very pleased with my SB3. For the price, it is unbeatable.
However, I would have loved an SB3 audiophile version which could be
slaved to a word clock and with balanced digital output (AES-EBU). The
PSU could possibly be upgraded but that is not as critical as long as
we are still in the digital domain and if we have clock sync to the
rest of the system. Obviously I don't care about the DAC - an
audiophile version SB could be completely without DAC.

I have a dCS system (Verdi transport, Delius DAC and a Purcell
upsampler) and I have found myself using the SB3 (via upsampling) about
95% of the time. The difference is rather small compared to a CD from
the Verdi (but then again, loading it with an SACD is a pretty large
difference so I can't get rid of the transport yet).

Anyway - I don't think Slim Devices will ever cater for the audiophiles
(any further). They have done a good job for the mass market and it is
even borderline high-end quality. So - I've just started a project with
a media server PC.

I've just bought a Lynx Two soundcard (which has word clock, AES-EBU
in/out etc). Unfortunately that means I need something to put it in -
i.e. a computer next to the stereo. So I found the Zalman TNN300
(Totally No Noise) - a fanless PC chassis. I will simply design a PC
with this and the soundcard as a base. I was delighted to find that you
could simply synchronise 2 SqueezeBoxes, so I can slave a SoftSqueeze to
the physical SB3. That means I can still use the SB3 and the remote to
control the music - but in fact it is the SoftSqueeze and the
professional sound card that will be connected to the hifi, SB3 will
only be the interface.

By servicing the SoftSqueeze (i.e. using one of many programs to
convert SoftSqueeze into a windows service) I can get it to start
automatically so I never need to log on to the media server (don't like
Windows here, but the Lynx hasn't got Linux drivers).

This will cost around $2000-3000 to implement and that is basically the
cost of getting a word clock and balanced interconnection to the SB3.
OK, I'll get the spin-off of using the same server for video to our TV
so it isn't too bad.

It is all much cheaper than a high end transport anyway so I don't
complain. It's just a pity they couldn't put the right gear into the
SB3 from scratch, that would cost only a fraction of this. But I accept
the mass market thing...SB3 is still the neatest interface I've seen and
I will use it as that (only).

 Just curious, as I read that another member prefers the sound of the SB
 DAC to his audio mirror NOS DAC (can't remember which member, or if it
 was a daydream).

Let me say this. After finally upgrading my amp last week, after which
I noticed a huge difference in sound, it made me realize the DAC does
not make nearly as much a difference. I do feel the NOS DAC has a
slightly less fatiguing sound, maybe a little more laid back, with a
little more slam in the bass. But those differences pale in comparison
to the difference with my new amp. Therefore, to my mind, it make more
sense to spend the bulk of my money on a better amp and speakers, and
then perhaps, worry about the DAC later, if the sound still leaves
something to be desired (of course, I didn't do it this way and
hindsight is 20/20 etc). To put it another way, I was missing
something before I got the DAC. The DAC did not fix it, so I was
still searching for that missing thing. With the new amp, I feel like I
found it. I am content now. I could go on listening to my current
system forever (I think) without a burning desire to upgrade again. 

Now, I don't want anyone to think I'm saying that it is specifically
Parasound amps that are so great. Rather, it is probably the case that
there is some threshold above which an amp can be really good, and you
can hear a tremendous improvement. Once you get an amp above that
threshold, and similarly speakers above a certain level, I'm sure the
DAC makes an additional improvement, but not nearl as much. If I had to
make a pie chart of how much each component contributes to the sound, my
guess after my recent upgrades is it would go something like this
(assuming no pre-amp):

speakers: 65%
amp: 25%
DAC/source: 10%

So, in the future, I will allocate my resources accordingly. For
example, if I were given (or earned, I suppose) $10,000, I would spend
$6500 on speakers, $2,500 on amplification, and $1000 on a source/DAC.

Jeff,

I'm not saying that Dan is always like this -- and, surely, he knows
quite a bit about TacT equipment.  Cables, of course, are a matter of
personal taste and philosophy :)

Having said that, Dan has a well-earned reputation for being a

people down, and otherwise harassing those who do not share his views. 
For this reason, he was booted off of Robert Greene's audio forum, much
to the relief of others.  Some people just let, well, something go to
their heads when they can hide behind the veil of email and web forums
and willy-nilly mistreat others.  In real life, a lot of these people
are, I suspect, rather demure and insecure.  Invisibility brings out
their bravado.

Anyway, look at the style and substance of his posts to and about me. 
Bear in mind that I played no small part, along with half a dozen
others that I know, in getting him booted off that forum for bad
behavior.  Can you say resentment?  I sure can!

Anyhoo, no flames from me and I do appreciate your input.

A I got the ball rolling on this one, I can try an answer...

Whether a powersupply is linear or switching does not imply quality or
the lack of it. You are right there. 

The reason I am sceptical to switching powersupplies in an audio
setting, is in the way they work. Switching power supplies chops up AC
to a higher frequency so it can use a small transformer. This is
usually done to save costs or space (linear PSU needs larger
transformer that are expensive and heavy). 

So what? you may ask. A badly designed linear PSU will introduce
ripple into your sound system (50 or 60Hz) as it doesn't have adequate
filtering. But that's it, and it is cheap to filter out. A switching
powersupply will add a high frequency noise in addition, so you need to
filter both the 50Hz (or 60Hz) and the high frequency introduced with
the switching technology. As an example: I have experienced more than
once that switching PSU's have ruined FM reception when I have had a
switching PSU close to my FM tuner. 

So basically, my experience with switching PSU's are that they don't
belong with quality audio equipment. 

Hope that this did clear up a few points.

that if an amp measured the same, it sounded the same has been
discarded by audiophiles and even normal serious listeners
this century. I take that to mean that the measurements
are missing something, maybe not measuring the right thing.

Another serious thing to consider is room acoustics, speaker
placement, listerner placement, etc. They have a huge impact.
And placement changes are free.  However, there is a problem,
in that the optimal positions for most setups have a totally
unacceptable WAF.

And room acoustic treatments are much more effective and
cost effective than they are in the WAF department.

But if you can swing the WAF, you can put, say, $2K into
room treatment and only need to spend $3K on speakers,
saving some money to increase the WAF with some nice
resturant dinners.

Interesting numbers. The last few times I have been to Hi-Fi shows,
there have been many who say that you need to spend a lot of money on
the source (CD-transport, DAC, etc.). Their argument is that the the
end result cannot be better than the source...

I don't have a DAC, and my numbers are somewhat different:

speakers: 40%
amp: 40%
source (SB2): 11.7%
cables: 7.3%

I have tested an Elektrocompaniet DAC (ECD-1) which costs the same as
my speakers, and the improvement was amazing. I am not sure if buying a
set of speakers costing twice as my current kit will give me the same
improvement.

 The reason we don't recommend a PC powersupply, is because it is a

 If you ever have opened a PC powersupply, you will notice that the
 transformer is tiny, it contains lot of electronics, and the remainder
 is heat sinks. Look at the powersupply of a typical 2x200W power
 amplifier, and the transformer is huge, weighing a few kilo's!

Thanks for the info. It was interesting to read the stereophile article

cheap. Note that the PSU is heavily filtered, multiply rectified -
this is quite different from the stock SB powersupply and the typical
$30 PC PSU I have been talking about.

it's just like with computer programming in that you keep improving

Ouch! You wouldn't want that. It's a 12V not 5V. It woild fry your
squeezebox.

You should look for a 5V (V = Volt) PSU. Should be 1.5A or more (A =
Ampere). The squeezebox uses about 1A at the peaks, but an engineering
principle says that you should use a PSU that is capable of the double
of your need. Note that the Voltage must be an absolute; the amperage
of the PSU can be larger.

Yes, that makes sense. As I don't have large sums to spend, I have to
improve my kit in as small sums as possible (That explains the cable
expenses). For me, I think a DAC is the next stage.

I've looked into getting a linear supply because:

a. I'm an inveterate twiddler with a background in electronics
b. I'm interested to see if it does make an audible difference on my system
c. They're cheap

I am in no way unhappy with the sound of my stock SB3. That doesn't stop

I was pointing out that the standard SB PSU is a switcher. And switching
PS circuitry is used internally within the SB2/3.

Correct me if I'm wrong, but there are those who think that the stock SB
sounds pretty damn good.

So it seems a little strange to suggest that it is wrong to advocate the
use of switching PSUs in audio electronics.

Equipment is important, but attention to detail sometimes makes an even
bigger difference. Or perhaps I should say a more important
difference.

In my experience an expensive system that is good on paper can have
problems sounding its best unless all connectors are in very good
shape. I used to clean all contacts at least every month, but
deteriation unfortunately happened in a matter of days. I got lazy and
started to settle for cleaning by removing and reattaching connectors.

The effects of cleaning was usually dramatic, but the magic didn't last
many days.

I now use SST (Super Silver Treatment), which gives better effect than
I used to get by cleaning, and seems to last much longer without any
maintenance.

I have no affiliation with the SST-manufacturer.

P.S: I believe a lot of the upgrade-mania is driven by deteriation in
connectors making the system perform badly. Symptoms to look out for
include: Systems sounds good after hooking up things afresh, but with
time the fun of listening goes out the window, and listening becomes
more of an effort.

No objective proof, just ideas from various forums- including this one.
Linear supplies for digital sources tend to be recommended over SMPS. I

I agree.

For me, it is ok that Slimdevices deliver the SBx with the PSU that
they have toady. But they should sell a linear one to us freaks as an

 Where the comment even came from, considering this discussion was about
 powering a squeezebox.
 
 Of course an SMPS is ok for charging your cellphone, but what's that
 got to do with this conversation?
 
 Thinking SMPS's are bad for all applications is not audiosnobbery, it's
 stupidity. Why state the obvious? Surely you weren't advocating thier
 use in audio electronics?
 
 So I'll ask again, what is your point- in relation to the topic at
 hand. Are SMPS's bad for the SB? Have you hooked a good regulated
 linear one up to it? Or are you just playing engineer on TV.

I hesitate to wade into the linear versus switch mode power supply fray, not
having the physics/EE background, but I can't refrain from noting that in
the world of Linn enthusiasts, the later switch mode power supplies
(Brilliant SMPS) seem to be typically rated as sounding much better than the
earlier linear power supplies (in otherwise similar components such as
preamps). (I have never made any comparison though.) It would seem that
there are SMPSs and SMPSs...

Let's see...ahem.  Okay, now that everyone has read the entire thread:

Who started this?  Who began with the insults, baiting, teasing
whatever?

That's right.  Dan himself.  Lord, may he get a life.

 No objective proof, just ideas from various forums- including this one.
 Linear supplies for digital sources tend to be recommended over SMPS. I
 don't have the equipment to prove anyone wrong, so I go with the flow.
 You, on the other hand, seem to want to go against the flow, but with
 no recommendations. I would say you have the burden of proof in this
 case.

Do I have the burden to prove God does not exist? That'll be tough!
It's very hard to prove a negative. As a scientist, that is something I
DO know about. In this case the logical null hypothesis is: There is no
difference between linear and switching supplies in terms of audio
quality. Therefore, my friend, it is YOU that has the burden of proof.

 jumping in out of the blue and lavishing sarcasm, snootiness, and
 personal vendetta against a de facto stranger.
 
 That's right.  Dan himself. Kind words aside, I have known few people
 who have managed to get themselves thrown off a forum for exactly the
 arrogant and abrasive behavior shown here.  Kicked off a forum for
 being rude, and, it seems, resentful of it.  Point, set, match.
 
 Now, back to audio.
 
 As before, Dan, I put it to you that it is best for you simply to
 resist your inner urges and not reply to any of my posts.  I will
 likewise do the same.  You don't like me, I don't like you, we don't
 respect each other.  The better part of valor, then, would be to avoid
 each other, not step into conversations, etc.  Got it?  Is this hard to
 grasp?Mahalo.


Please keep the flame war under control here. The forums are here for
people to discuss things related to audio and Squeezeboxen, not be
derogatory towards eachother.Thank you.

Kevin-

Thought you asked for the flames to stop?
