Moron. You really have no concept of how slimdevices work (or the real
world of networking for that matter.)

Two approaches:

Ipeng in the app store (has an advanced interface similar to Touch.)

Use the webUI via safari on the new iPad. 

Vortexbox is a fine piece of work that will run on any Linux. You don't
mention having another computer to run it. It does not run on an iPad.

Pete,

My first higher-powered (and better phono-cartridged) stereo had DCM
Time Windows (and later, Time Bass.) Everything was paper, and not just
in my speakers. This was before poly or any other exotic drivers (except
JBL.)

My only argument with the above is that it's the precision of placement
with dipoles, not just the correct distance. You can use 1/4" instead of
1/8" above as long as the speakers are 1/8" in agreement with the back
wall. You will know when you are too far away from the wall,

My "old time" instructions for managing a bi-amp setup could be helpful
if used in reverse:

Set the bass segment and the treble segment to maximum volume. Play
music at a reasonable volume and reduce the treble gain until the music
sounds "normal."

The is very simply done with an active crossover but most subs just
have sub gain control so you end-up starting with no sub gain and
adding slowly.

For sub-satellite setup, I agree with Dynaudio: let the satellites play
full range. (Assuming the satellites are substantial.)

A well done sub is very subtle. Don't be tempted to want to hear it all
the time.

In a smaller room, avoid having the driver parallel to it's back wall.

Amps

In the common retail market, only Yamaha posts full range power (rather
than 1K.)

See also Crown  and QSC. Toroidal is good. In my

Speakers depend entirely on your airspace which you haven't mentioned.

The volume control in ALL the products is digital. My confirmation was
that the limit parameter only had an effect on the analog outputs.

Do attenu-tators turn your 'taters into antenna?

Thank you in advance for your clarification.

Yes, it only affects the analog outputs (if the 'i' button is correct.

SB3 has a preamp output limit.. I wonder why that wasn't done on all
the players??

Also, SBR output direct to a power amp sometimes does not play loud
enough (even with replay gain adjustment disabled.)

The various models of Magnepans have very specific instructions on
placement that answer all your questions about starting position,
separation, and adjustment distances.

Of course, it is possible you don't really want facts in response to

So calm down. More data: yes. Sending WAV: the only issue is whether
the link can take it. If it can't you will have gaps. Remember: boxen
only have an empty buffer at the beginning of a track. The TCP/IP
"protocol actions and buffer manipulations" are all done in the network
interface card so you are left with the doubling of data and the WAV to
FLAC conversion.

List a few of those "many factors" if you will.

Things are not how you think they should be.

Your fault is to assume the results are dichotomous. Heads/tails:
independently dichotomous. "I hear the differences" will never be a
"very clear-cut binary situation" because there is not proof you hear
well 

If two "audio configurations" are different, there will be a measurable
difference. We invite  a demonstration of
measurable differences.

people have the same imaginary friend, they are all crazy.

If you don't mind my reply, the "cores" you refer to are 
used to reduce analog "hum."

Years ago  I realized I could use "computer grade" cable to
connect the stereos in my home at "line level." The three stereo
systems joined in a switch. By using the "tape monitor" inputs and
outputs I could make things work almost as well squeezeboxen.

Ferrite rings at the end of each connection prevented hum in the
circuits.

This is not to be confused with current digital wiring. Such
physics-based rings can not have an impact on a digital signal's
quality.

You have something else playing?

Most of this is based-on dispersion and the distance from you to the
speaker and the speaker from the side and back walls.

I'm not directly involved with QSound and I really hope you are not
here to sell it.

The interactions of speakers and their environment is complicated

Please re-read the question. Playing a 64kbs stream can only be
"improved" by increasing the bit rate. It's something to do with the
lack of information. Of course it could be digitally equalized but then
"improvement" would be completely an opinion.

Congratulations on your esteemed equipment ! 

I will suggest your coarse attitude is not appropriate.

As well, the sound at the "bottom" is important. Does the speaker "drop
off like a rock" or "make a graceful exit" rather than burp and fart?
There's a little subjective issue here.

Where the speakers sit in the room and whether the amp has enough are
the questions. Expected volume is the other variable.

I call it "environment." 

It's a sad story of fried amps but a nearly happy ending: 

When I first got my infinity speakers, they replaced bi-amped DCM Time
Windows/Bases. The first hook-up sounded so good I gave 'em a lot of
wrapped dollars in a strawberry basket.

After I'd slept, and after I'd fried my GFA-1, and after I'd borrowed a
GFA-555 , and after I had a
walk outside behind the speakers, I realized that having 3 feet behind
the speaker wasn't the issue. I had to deal with the square faced house
next door. The bass to the rear was not impeded by my 1950's
construction.

To make a long story short, long live active crossovers ! They can make
your house sound better

Ignorance is bliss: I've always been impressed with Mark Levinson power
amps (that are not located in Lexus cars.) Since my main speakers are
the world's hungriest, accurate .5-1 ohm is really enticing.

Of course, they are now owned (like everything that used-to-be-sacred)
by Harman Industries. These things happen.

Electrocompanie driving Focals was also impressive since the room was
totally wrong (short side front to back and the size of mobile home

I did this test on my recent ScanSpeak build and the pink noise raising
71db, there was a jump from 84 to 88db at 35hz. Madisound had said Bass
Box 6 Pro predicted an F3 of 35.5hz. I guess the ScanSpeak specs are
fairly accurate.

Jeff,

You gave the roll off. While the makers may say +-3db, it's almost
always minus. This is also known as F3 and it's the frequency where the
output has dropped by half (over simplified.) Each 3db doubles (or
halves) the output so F6 would be 1/4 of the output, F9 would be 1/8 of
the output.

I say this is over-simplified because at low frequencies (like everyone
else has said,) room dynamics can damp or enhance bass response.

When it comes to position, check the instructions to see how far from
the walls the maker recommends. This placement has a direct effect on
bass response. If they are closer than 12-18 inches, they are probably
suffering. How far apart and how far away has more of a stereo imaging
effect.

I prefer the Hooter's definition: "Delightfully tacky, yet unrefined."

parameters (Bose is good, right?)

- you buy new flat screen TV only because it's part of a deal at Rooms

- you are unconvinced that it is only possible to hear differences
between two audio systems due to the fact that such differences exist
only in your 400-600 sq. ft. apartment and a room the same size

- you insist in connecting your speakers to your power amplifier with
jumper cables

- upon buying an expensive new amplifier, you immediately plug the
power cable into a $4 6-tapper because you read in a forum that it's
the best thing since sliced bread

- you enjoy participating in the race to the bottom by frequenting
Walmart stores in search anything in the electronics department

- you convert all your digital music library to 320 kbps aac because
even if it is impossible to hear any difference Apple let you upgrade
for $25/year

- you frequent audiophile forums looking for people to help because
they really need it and because you can. Of course some people already

[SlimDevices: Audiophiles] Some folks are proud of ignorance

2012-01-27 Thread pski

It's sad that facts merely get in the way of people who are proud of
their lack of knowledge.

"The Way Things Work" does not equate with understanding everything.

Colbert popularized "truthiness." This use is a corruption of the term
Verstehen.

Verstehen in the sociological realm means "gut feeling." Sometimes it
works and sometimes it is wrong.

Truthiness is similarly detached from reality except it approaches
religious fervor. At times it incites political posters, chants, and
political rant. Truthiness is always right, by definition. The
definition points out that reality or an appreciation of reality is not
involved.

To the unicorns:  brain farts are defined in the literature
as things that propagate complete disconnects.  brain farts
improve the quality of your music  by reducing it to pure zeroes. 

Note: There can be no improvement on pure zeroes when it comes to a
data stream.

The NIC notices the "connection" (which is required in TCP/IP) goes
away and based on the retry and time out parameters of the software
running on the NIC reports "a network cable is disconnected" for wired
devices and the program/service using a wireless connection just times
out. How your O/S reacts to a wireless disconnect varies widely.

2012-01-27 Thread pski

I use the ART USB V.2 with a Sony belt drive and an Audio Technica
cart.

I don't diddle with output from a equalization basis so I use a simple
program called spin-it-again.

It presents a "cassette recorder" analogy: start play-hit record-play
side-pause-flip and repeat.

At that point the program has a go at identifying where each song
starts and stops and will preview this for you. It's a button you can
use any time.

The songs' stream is shown in a wave form and you can drag the
starts/stops and delete/insert track points. You can also stretch and
shrink the wave time-wise to finely pick starts/stops.

You can also adjust the "playback" of each song by percentage in case
you recorded at 45.

There's an album look-up that is sometimes effective.

I usually use the "gently clean" option to get ride of pops & such.

Different cables have different ratings because they vary in materials
and construction. High thru-put cables are not straight wires. They
have very intricate loop-backs. This is done to allow smaller wires to
carry high frequency signals without extensive cross-talk. Just take
one apart to verify this. TCP/IP used to go only 10Mbs. As faster
speeds were codified, wires had to get better. A Cat 4 cable may be
able to carry 100Mbs a short distance but at longer distances physics
steps in and retry rates limit thru-put. To carry TCP/IP at the highest
speeds (and the distances set out in the specifications,) more carefully
designed cable is necessary.  "Noise" is an analog term. Since the
derived data is digital, "noise" on the line is irrelevant. See #2.>

No. Parity testing/reconstruction/request for retransmit operations are
done in the NIC (network interface card.) The CPU doesn't know anything
about it. When your O/S displays packet statistics, it has just asked
the network card how things are going.

So, yes, bit perfect data does means the data that left the one end is
the exact data received at the other.

Not to mention the other obvious benefits they possess: The ability to
remember tube part numbers up to ten characters and their associated
sound as well as well as their damnable ability to make patterned white
bread toast on their amplifiers without have to miss a single strain of
music.

Or, I would add can hear hairs splitting ..

Everyone is entitled to his own opinion, but not his own facts.-
Moynihan

The LMS sends data perfectly (in effect due to the TCP part of TCP/IP)
to the player(s.) 

The players buffer the data and using the excruciatingly accurate
clocks in their DSP's create an analog (or pass along a digital)
signal.

So long as the TCP/IP link provides sufficient bandwidth to support the
music stream, changes to the LMS can in NO WAY alter the resulting sound
quality.

So long as the squeezeboxen receive an adequate stream of data from the
server, any changes to the host hardware/OS will only result in an
improvement in the speed of the user interface.

No improvement in sound quality will result under any circumstances.

Sound quality in this system is determined by the D/A converters in the
players, the capability of your stereo to play them, and the bit
rate/depth of the music file.

Worthy tweaks:

1. Read and follow the speaker maker's instructions on placement. Very
few  speakers are designed to sound correct jammed into corners
or close to a back or side wall. If the speakers don't have
instructions, get better speakers. If you are forced to place speakers
based-on aesthetic appeal, you might want to consider what other
compromises you are making in your life.

2. Disengage the "loudness" button and bypass or neutralize any tone
controls or equalizers. "Source" and "Volume" are the only True
Controls. Active equalization in modern sub-woofer applications have an
exemption.

3. If you MUST worry about supply A/C, worry that your supply current
is sufficient and that grounding and polarity are correct. Have an
electrician set a dedicated breaker to your stereo rather than
subscribing to power cable mummery. I have a power amp on the bottom of
my Kappa 9's that was eating 6 amp fast blow fuses faster than a
teenager eats Tic Tacs. When I moved from that house (60 amps total
service/aluminum wiring) to my current home, the cure was effected.

4. Avoid any product containing the word "Monster." Avoid any salesman
or vendor that points, gestures, or suggests any product containing the
word "Monster."

5. If you want to be sure your interconnects are good enough, keep them
away from power cables and you'll be just fine.

6. Rotate your tires.
