Re: [SlimDevices: Audiophiles] Squeezebox Duet and Beresford Caiman DAC

2010-04-30 Thread dogsnadgers

Hi
I have been meaning to do this for a while, when first installed I
couldn't live with the Duet against the CD5i, the sound was dull and
lifeless in comparison, the DAC solved that (bought used, so already
run in).  Approx nine months on the Duet is well run in and the
difference is not so great but it is still noticeably better with the
DAC than without, just more of everything, more life and groove, more
toe tapping! I would be very interested to try the Caiman or upgrading
my DAC internally, from what people are saying (I haven't heard one) I
reckon a Touch might outperform a standard T-7510 so might need a
Caiman to improve it.  I put my Panasonic Blu-ray through the DAC for
music DVD and I can't tell any difference whatsoever between the DAC
and anolouge output from the TV, so may try a Touch and not bother with
a DAC, decisions decisions!

HI,
Im using a Touch with a modded Caiman Dac.
I've upgraded the Regulators and the Output capacitors, which gave a
great upgrade to the standard Dac.
Its fair to say that the Dac Im using is a fair bit better than the
standard 7510(I've also owned a 7510 MK6/3 and a standard 7520), and
I've compared the Touch analogue with it running into my Dac.

The Dac is better..more of everything..just plays music not hifi.

That said, I could live with the analogue outss on the Touch if I didnt
have the Dac, its very very good, a lot better than the SB3 I owned
previously.

Guess Im saying you would get away with just using the Touch on its
own, I'd equate it with a very good £600 CD player...but as a digital
transport its capable of a whole lot more.

I'm upgrading my Dac again because of it!

 Your last test has already been done, as I posted earlier.
 The fact is that people cant hear a brass marching band stuffed into
 the bottom bits of a 16-bit file playing Brahms Lullaby!
 
 Ironically, if they could, reducing the volume would eventually lose
 the Brass Band but leave the Brahms...
 
 You are also missing the point about human hearing vs what systems can
 actually do in terms of dynamic range. There are very few hi-fi systems
 that can generate 120dB of clean sound. Even so, the human ear cannot
 actually hear 0dB and 120dB AT THE SAME TIME (especially if the ambient
 noise level is at a realistic 50dB).
 
 Yes the loudest sound we can comfortably tolerate for a short while may
 be 120 and the quietest we can hear might be 0 - but the ear+brain
 doesn't work like a perfect microphone! It has to make choices.
 
 The ear-brain has a built-in AGC to amplify very quiet sounds and a
 sophisticated compressor that protects us from loud sounds. The
 practical result of this is that the actual perceived dynamic range is
 much less than theory would imply. Probably more like 70dB, but the
 baseline datum point moves - this is the important point. IF the max
 level is 120 you can probably only hear down to 50 - if the max is 70
 you might be able to hear 0...
 
 
 I'm still not clear exactly what effect you think digital attenuation
 has on the sound?

Re: [SlimDevices: Audiophiles] DAC Resolution Test and Don't EVER use Digital Volume Control

2010-04-30 Thread darrenyeats

Imagine sitting a comfortable distance from your 50 1080HD TV screen.
Imagine someone reduces the size of a picture from fullscreen to
1/128th the size - a 7 bit reduction of digital volume to a dithered
15x8 pixel image. Is the image noticeably more pixellated than with a
fullscreen image?

If you pushed your nose against the screen or if you blow up the 15x8
pixel image to the full 50 you will notice the distortion on the
smaller image. That's irrelevant to this discussion.

On a 50 TV the size of the picture is now less than half an inch
diagonally! If you stay at your comfortable distance from the screen
the smaller image will not suffer because of the lack of pixels because
it's too small for you to see! If there were a way to render 150x80
pixels into this same postage stamp of screen area would you notice the
difference? (If so, I suggest that means you can see pixellation on a
fullscreen image from your sitting position.)

I think this is a pretty good analogy for how a digi volume control
works. Either you can perceive distortion in a 16 bit signal (at full
volume or low volume) or you can't. Reducing digital volume doesn't
change whether or not you can perceive digital distortion.

If you can't notice digital distortion at 100% volume you won't notice
at reduced volume either. If you can hear digital distortion at low
digital volumes you should be able to perceive it at 100% volume too -
and that has nothing to do with digital volume control.

The big assumption here is comfortable distance from screen which is
the equivalent of setting up your analogue attenuation right. Not
optional, absolutely essential.

While the display is nice, having a broken display is no reason to throw
away a Transporter. I rarely pay any attention to the displays on mine.

Of course, if you really want a display, the one from a salvaged SB1/g,
SB2 or SB3/Classic will work fine.

Or, one could buy a couple of Touch units, and use the displays from
them in the TP housing. Its huge and mostly empty.

This is a trend not just for the TP, but for nearly all stuff with
non-trivial electronics, and that includes any car made this century.
Years ago, I could rebuild the four-barrel carb on my Pontiac 389 V8, as
well as nearly anything else on the car. With modern fuel injection and
mixture and spark advance systems, they are considered black boxes that
are replaced.

Even TVs have become like toasters, use and throw away.

Makes me glad I didn't stick with the Transporter when I did the trial
evaluation three years ago. 

This weekend I have to replace the failed hard drive on a nine year old

 While the display is nice, having a broken display is no reason to
 throw
 away a Transporter. I rarely pay any attention to the displays on
 mine.
 
 Of course, if you really want a display, the one from a salvaged
 SB1/g,
 SB2 or SB3/Classic will work fine.
 
 Or, one could buy a couple of Touch units, and use the displays from
 them in the TP housing. Its huge and mostly empty.
 
 This is a trend not just for the TP, but for nearly all stuff with
 non-trivial electronics, and that includes any car made this century.
 Years ago, I could rebuild the four-barrel carb on my Pontiac 389 V8,
 as
 well as nearly anything else on the car. With modern fuel injection
 and
 mixture and spark advance systems, they are considered black boxes
 that
 are replaced.
 
 Even TVs have become like toasters, use and throw away.

I understand the Transporter still works without a display, but most
people who buy high-end audio items also value the appearance, just
like auto enthusiasts who work as hard on their car's cosmetics as they
do performance. 

I understand that one can cabbage parts from other SB models. The
question is whether that's appropriate one month out of warranty. And
as for using a Touch screen in the Transporter cabinet, who wants their
$2,000 high-end toy looking like it was a jerry-rigged entry in a You
might be a redneck... contest? 

As for the carburetor on your Pontiac, I bet you can still get it
rebuilt.

For me, I don't have a Transporter, so I think I'll cease worrying
about how to fix what I don't own. ;-)

 Makes me glad I didn't stick with the Transporter when I did the trial

 This weekend I have to replace the failed hard drive on a nine year old
 Dell PC. (Don't laugh - it's one of three at home and for what it's
 used, it is as fast and stable as the one year old machine I use at
 work.) 
 
 Kinda sad that the Transporter's repairability can be upstaged by an
 old Dell

Not laughing - but it's a very unfair comparison. PC's are made from
modular, pluggable, generic components (excluding laptops - which
certainly are in a similar boat to the TP). The TP is mostly made from
bespoke devices, apart from the wi-fi card and some of the components
on the mainboard.

Pat is right, the world has changed (not for the better IMO) in the
last 40 years in this respect. It's the price we pay for cheap(er) to
buy - expensive or impossible to fix.

If you want Linn/Naim/Quad/etc long term support you really DO have
to pay for it. I made my decision 20+ years ago and so far it has
worked out. However, I know if my pre-amp died I would probably have
trouble getting it fixed... and a replacement would be £7k :-(

For the prices one has to pay for (to buy and to fix) other high end
audiophile stuff, there is no reason for a Touch's screen to not look
perfect. Its about the same size.


 As for the carburetor on your Pontiac, I bet you can still get it
 rebuilt.

I'm sure that it can be for a price. But what you can't do today that
you could when I had it, was go into any local autoparts store and buy
not only all the parts, but all the other needed stuff, like the evil
carb cleaner fluid.

For one, there are far fewer autoparts stores. More importantly, the
local autoparts store no longer carries such parts. Back in the day,
everyone had to rebuild carbs, now only a few specialists know what a
carb looks like.

 For me, I don't have a Transporter, so I think I'll cease worrying
 about how to fix what I don't own. ;-)

Seems a bit weird that you were so concerned, while the TP is still for
sale, its no longer a $2000 product and its not getting any press.

Even audiophiles like their tail fins.

Yes, but your grounding and standing is pretty weak since you don't have

I might complain that a Ferrari gets crappy gas mileage, but folks in
the market for one won't see things the way I do.

The people who designed the Transporter left the company. The new
company has a different culture, different priorities.

Perhaps they will be interested in an niche audiophile product, but I
expect not. It was more of a an engineering exercise by  a few talented
folks, as are nearly all audiophile products.

Nearly all audiophile products are made by companies with under $5
million in sales, and often they are under $1 million. I don't know of
any high-end brands that are multi-national, even the well known ones,
like Meridian, or Wilson Speakers, are tiny in the normal world of commerce.

I expect that today, I would not buy another Transporter if mine goes
belly up. I never use the fancy knob, and the dual displays are just fun
eyecandy. Its sure not worth $1700 more than a Touch to me. I'd rather
have two or three Touch units. But back when the Transporter came out,
there was nothing like it.

And it still sounds pretty darn good.

 This is so true. Does anyone really think engineers/producers sit there
 in studios, staring at banks of digital faders (real or virtual or
 both) and think hmmm, better not touch any of those in case the sound
 falls apart..
 
 No they don't. They mix/master the tracks!
 Clive is right, this thing is so silly.

Your damn right they do. Or the software/hardware they use does a lot
for them. The Meridian 518 was an early device used by mixers to dial
the gain in among other things. I've looked at a bunch of CD's with
Audacity and the pristine ones always take full advantage of all the
dynamic range and have just an itty bit of clipping. Good CD's never
throw bits away. Where poorly mixed CD's are over attenuated (to much
headroom 6,9,12dB). They don't sound bad but those are never the great
sounding ones. And other poor ones are of course the way over
compressed ones and not taking advantage of the lower bits.

In fact here is the Meridian 518 Manual that discusses this very
topic.

http://www.meridian-audio.info/public/518user[120].pdf

See page 19.

The 518 allows you to tweak the Digital Gain (of each Piece [an
album]) to Maximize the performance of your DAC (NOT for LOUDNESS,
sorry if you don't get that, if you don't, stop reading and move on).
That's why they call it Secondary Gain. The system also has a
Primary Gain which is ANALOG. We are talking SMALL digital changes
here to optimize performance. Not -20dB which would totally butcher
things. You'd typically use a 518 to boost an album to Full Scale
(what they refer to as Full Digital Code).

If anything you'd want to go ABOVE 0 on the Transporter if an album is
not mixed full scale. That's basically what a 518 does. You'd never
want to attenuate unless you doing some sort of mixing.

But what does Meridian know about digital stuff.

Well, the thing is, it plays the transcoded wav just fine and that's a
higher bitrate than the native flac.

Also, I've re-flac'd the files using flac -5 and they work OK.

Sorry I don't have much time right now. But exactlty that. An itty bit

fringes than to compress or attentuate just avoid clipping a few

Let say you frame pictures and you want what ever it was centered. But
there was twig on the edge that would get clipped if you centered it.
Is it better to be off center (your goal) or clip the twig? Or even
worse put an over sized frame and pad the whole picture with a white
border except where the twig protrudes?

 I'm sorry that the clipping I'm referring to is beyond your grasp.

I write software for Mass Spectrometers. We sample at 4Ghz. We
determine the speed at which IONS fly through a vaccum in order to
determine their Mass.

We have dozens of DACs and ADCs and I understand them quite well. We
oversample from 2 - 2 million times. The we use an ADC that cost around
$23K each (that's discounted in volume).

I also have written a childrens programming language and digital
simulator I publish for free and used in many schools and colleges.
Hence the name mswlogo.

I also run the Meridian forum for 10 years. And have invested about
$40K in Meridian audio. And I want every ounce of performance out of
it.

Is that specific enough for you? Do you need my full resume?

I would provide you some real examples with wave forms to explain how
this works but you folks are so close minded I think I'd be wasting my
time.

I gave a fairly good example.

Here it is again slightly changed.

Think of a photo that is 24 x 24 inches.

But your frame is 16x16.

Where is the best place to place the frame?

The important content is in the middle !!

Do you place it on the upper right corner?
So you won't Clip the upper right.
Oh my that would be terrible to clip white sky with a tiny bug in it
you can't see from 2 feet away. Let the bug clip so you can get some
nice grass on the bottom. It adds to the WHOLE picture.

You place it some where in the middle.

You could compress the photo to fit but that has problems too. But a
little compression is ok.

It's a balance !!!

Don't ignore the bottom (even if it's low level).
Don't be parnoid about the top either (if it does not persist long
enough you won't hear it).

And don't F'k with the frame once it's been placed by a good framer.

I did that in high school physics class, over 40 years ago.
