Today, probably not. But DVD is dying too. The BlueRay war was a case
of winning the battle, but losing anyway, they vanquished HD-DVD, but
BlueRay disk sales are not what the studios expected.

Its all download now. I expect the trend is unstoppable.

When DVDs came out, I bought three players and perhaps 100 DVDs, but I
don't use them. Unlike music, where I want to listen to it over and
over, except for a tiny number of movies, I watch them once and am done.
Perhaps after 10 years I'll watch it again if its really great. But most
movies are not great, and after ten years, none of my initial set of DVD
players work.

how it suppresses noise.

Nothing with two wires is going to work for long cables.

How long is long is a personal question, to me, 6 feet (two meters) is
all I trust.

It depends on so many other things, many of which are uncontrollable.

Mains cables, even in walls, florescent lights, etc.

That means it is realistically non-existent.

Typically, down 70 dB means cut out completely since humans only
have about 90dB of range. Plus a quiet living room is typically 35dB,

atrocity;311245 Wrote: 
 It's too bad most (all?) of the hybrid SACDs from old analog masters
 (Rolling Stones, Bob Dylan, Pink Floyd) contain DSD to PCM conversions
 on their redbook CD layer.  

RedBook is PCM. To get PCM, you have to convert it. Whether or not
there was anything there to being with.

Old masters were typically either 2 24 track or 1/2 stereo. The terms
get misused a bunch. The tracking tapes were nearly always 2 24 track,
unless you go back to pre-Sargent Peppers days. (Some of the early
Beatles stuff was recorded in mono.). The 24 tracks are then mixed down
to stereo and put on two track 1/2 tapes sent to the mastering
engineer. For Vinyl, mastering was an art. So the mater tape in was
really the 'mix down' tape, and the output of the mastering engineer
was stereo sent to the pressing plant.

None of the 2 machine had much frequency response above 20kHz. Most
didn't have any, but it hard to generalize. Most used Dolby or
something like it, long before Dolby became popular in the mass
market.

If the tracking was done on a typical Struder 2 machine with Dolby,
there isn't much pure signal about the 20kHz that red book can cover.
And Dolby processing is audible if you pay attention and have good
gear.

Re: [SlimDevices: Audiophiles] Amp has started popping

2008-05-16 Thread pfarrell

No clue as to the cause, here is a hint at isolating the problem:

Do you have any other sources? An FM tuner would be idea, something you
can plug into the same connections on the amp and play music for a
while?

Or try other RCA connectors on the amp, and see if that changes
anything.

I had a Sony receiver that worked fine for about a decade and then
started getting all sorts of weird stuff, channels dropping out, phono
section getting noisy, etc. I did the problem isolation thing for a

Re: [SlimDevices: Audiophiles] please urgent answer - want to be shure

2008-05-11 Thread pfarrell

You can't be sure. (Shure is an audio company, makes nice microphones).

The recommendation is to validate that the system can run at wide open
volume from your SB3, through the amp to the speakers. If you can
listen to it, then you are probably fine. But if you need to use the
SB3's volume control to keep from frying the tweeters, then you may
have a problem in the rare case that the SB3 software gets weird, has a
bug, etc.

So the recommendation is that if your system can't run wide open
listening to music, you should get either some attenuators, or use a
preamp.

There are nice audiophile attenuators that are fairly inexpensive,
search the forum archives

As others have pointed out, the fuse is short. One could argue that
resistance is really measures in x milliohms per foot for any vaguely
useful cable, so if the speaker cable is marginal and long, it might
make a difference in voltage drop. The fuse element is typically short,
fractions of an inch. But once the cable is long, its resistance is big
enough then the resistance of the fuse drops out of the equation.


In general, there is no point in an four-OUGHT cable when there is a 18

David Bendeth, a producer who works with rock bands like Hawthorne
Heights and Paramore, knows that the albums he makes are often played
through tiny computer speakers by fans who are busy surfing the
Internet. So he's not surprised when record labels ask the mastering
engineers who work on his CDs to crank up the sound levels so high that
even the soft parts sound loud.

Re: [SlimDevices: Audiophiles] Square waves are not very helpful for audio

2007-09-30 Thread pfarrell

No argument, that was my first sentence.

But unless you are designing audio gear, I don't see the relevance. The
square wave picture on an o'scope provides a great intuitive picture.

But as a consumer, I can't use that information once I've bought the
amp, wire, etc.

You can't feed a square wave through to your speaker, or the infinitely
high frequencies will burn the tweeter before you can hear it.

And you sure can't sample it, even if you were crazy enough to think it
was music.

I even had an o'scope a while back, it was very old and the internal
caps became un-form-able. I've looked at prices, just for giggles
recently, and you can buy a very nice car for the price of a modern
o'scope.

[SlimDevices: Audiophiles] Square waves are not very helpful for audio

2007-09-29 Thread pfarrell

Thought this deserves its own thread.

Audio amp designers (and testers) use square waves in testing because
they can see the amplified square wave and get an instant insight into
what the amp is doing. Square waves are very hard to amplify, as they
are the infinite sum of an infinite series of sine waves. 

The 16/44 vs 24/98 thread talks about square waves at 20kHz being
sampled. This is at best misleading. For two reasons:
1) music doesn't have any 20kHz square waves
2) you can't sample a 20kHz square wave, per Nyquist's fundamental
rules.

I think #2 deserves a bit of explaination.

Before you can sample any signal, you must pass it through a low pass
filter set at the Nyquist frequency. For 44.1 kHz, the filter has to
pass signals below 22.05 kHz, and block all signals above 2.05 kHz.

Once you've filtered the incoming signal, then you can sample it.

But, what is not obvious, is that when you pass a 20kHz square wave
signal through a 22.05 kHz low pass filter, the result is a sine wave
signal at 20kHz. It may have some spurious harmonics, but the basic
output is a sine wave.

When you sample the sine wave, you get a stream of bits. When you pass
the stream of bits to a DAC, you get a sine wave.

You do not get a 20kHz square wave.

jt25741;231080 Wrote: 
 Indeed.  Nyquist says that any frequency above 2X the sampling frequency
 is garbage, and must be thrown out(filtered).  

The key word here is *must*. Its not optional, you must do it.

And one of the claims in favor of higher sample rates, and oversampling
in general, is that you can use simpler filter circuits. Many early
systems had 12dB/octave filters, which really screw up phase. The
designers needed the steep slope to avoid causing massive aliasing
problems. With 88.2kHz, you can use a 6dB/octave filter and be as free
of aliases as a 44.1 with a 12dB/octave filter.

The 16 vs 24 argument is less well grounded. Since recording engineers
consider -70 dB to be gone, the 96dB provided by 16 bits is overkill,
in theory. But there are established audible tests that show that
dithering of the 16 bit signal is important. With a few more bits,
dithering becomes less important. And in the days of PCs with RAM
enough to hold an entire RedBook CD in memory, adding a few bits is
easy and cheap.

Professional turntables are designed for the needs of professional

I don't think any real radio stations have used vinyl for decades.

In either use, the professional use is not about audio quality it is

If there is sonic quality you are trying to extract, I would strongly

There are a fair number of decent ~~$500 turntables, Project, etc.

A pro-audio shop is a good place to get phono preamps that are decent
quality and inexpensive. The audiophile shops seem to think that $3000
is a good price for a preamp that really is only good enough to feed

 Another slippery slope (or $lippery $lope)... maybe one day.
 

You bet.

My guess (only a guess) is that for occasional usage, the Behringer
would be fine. I'd expect that the Earthworks would work over time,
like a Fluke meter. But even Fluke meters are supposed to be calibrated
periodically.

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?

  Reading a CD isn't much different to reading a hard disc - both are
 digital, ie. yes or no, right or wrong. Why should playing a .WAV file
 directly off a CD-ROM via SlimServer be any different to playing a
 regular CD in a CD player?


It depends. An audio CD player reads the music per the RedBook spec. A
PC uses CD-EX to Extract the data. It is not the same.
Way back in the 90s, many PC CD-rom drives could not do the extraction
(which is essentially reading the digital data as you would read a hard
disk sector).

The normal RedBook way to read the music off a disk is very different.
The error correction is different, etc. Most of this is due to the very
limited capabilities of microcontrollers at the time when the RedBook
spec was written.

I believe, that if the spec had been written just five years later, it
would have been very different, using more of a digital approach from
the start.

 FF and REWIND that works as well (not better - just as well) as a
 circa 1982 CD player would be a start!

Rewind? Please be kind, rewind?

I'd love to see your mythical 1982 CD player. From the Sony site:
On August 31, 1982, an announcement was made in Tokyo that four
companies, Sony, CBS/Sony, Philips, and Polygram had jointly developed
the world's first CD system. These companies announced that they would
commence domestic sales in the autumn. 

I bought my first CD player in late 84 early 85. Before that, they cost
a grand and there were no CDs for sale, only records. The first Tower
Records opened in Washington DC at the same time, it was mind boggling
to see their store, they had over a thousand CDs for sale. And it was
only 5 blocks from The White House.

Aside from the history, why would you want a rewind function?
The only button on my SqueezeBox remote that I use is Play

  I came across musicgiants.com but its selection is pretty limited.

I tried to see what selection they had, and got this:

We're sorry, only Microsoft Internet Explorer is supported.

so they clearly don't want my money.

[SlimDevices: Audiophiles] Re: Does an amp need a preamp?

 There have been some threads elsewhere indicating that a pre-amp does
 something that enhances the sound quality - all the usual, soundstage,
 etc etc.
 

I can't see how adding signal processing improves a signal. But some
folks like to use tube pre-amps as tone controls. They can add a 'tube
warmth' which is usually just rolling off the top and bottom of the
spectrum.

And of course, tubes can add some nice intermodulation distortion.
Which is why I play my Gibson ES355 thru a tube Fender amp.
