 Why not getting a Northstar dac, or similar, used, rather than upgrading
 a cheap dac ?

Apgrade only output stage, and power supply.
The vdac is a hiend product, not look at the price.
To buy something like that should be paid also on the use x40.
was compared with EMM Labs DAC is one of the best ever, if not the best
and are very similar already without modification.

 THD+N is pretty useless as a sole metric, that is true.  Especially with
 loudspeakers where the on/off-axis FR measurements are more important.  
 But... when you are splitting hairs over 0.005 THD+N Vs. 0.0001 THD+N,
 it is almost guaranteed that there is little audible difference between
 the two.   Also, you have to more broadly define how it is measured. 
 Small amounts of odd-order are very audible, higher amounts of even
 order harmonics much less so.Also, you would have to know where the
 distortion components are in relation to the frequency band.   You can
 listen to 10% THD  at 20 Hz and not tell a distorted sinewave from an
 undistorted one.So... yes, it is more complicated than a simple
 single number but there is plenty of research showing what is and what
 is not audible. 
 
 With transducers, we are very happy to get 1% THD+N at higher listening
 levels.   Those distortion products are both even  odd order depending
 upon the mechanism causing them.I'd say we are pretty safe in saying
 that those non-linearities swamp those that are another 40-60dB further
 down.   It is like saying you can appriciate the sound of your hifi
 while using your chainsaw.  Nobody would consider that a rational
 exercise, yet we routinely make such comparisons when judging audio
 components.   The rational person, turns off the chainsaw before they
 fine tune their audio system for best performance.  The irrational
 person quibbles about the nuances of the performance while ignoring the
 chainsaw.

The distortion of 0.0001 in the mountain can generate a much larger
distortion because in our downstream facilities are amplifiers that
amplify everything that goes into even the input distortion ...
The DAC is selected if you want to increase the detail or to gain a
better scene to your own tastes.
You say that beyond a certain threshold rather low, (the DAC of the
Touch is pretty cheap) do not feel more different.

This is not true.

Want to support that most audiophiles are deaf?
There is an explanation to this.
The human ear is an instrument that has had thousands of years of
evulozione.
What we feel is interpreted by the brain.
This explains why there is a DAC with the same distortion feel
differently from other DAC.
Our ear is perfettamnte able to distinguish small changes that occur in
a very short time, while great changes continue over time are not
assimilated in the same way.
is why we feel the differences between a cable and the other in the
presence of a chainsaw as you :-))
I know that we are slightly off-topic:-D

 Sure.. I'm just pointing out that if you cannot hear a difference, then
 it doesn't matter.You don't get brownie points for making something
 less inaudible.   
 
 I think the Touch used as a server and outputting via SPDIF directly
 into a DSP or a DAC is the cat's meow.I see no reason why you need
 to spend more for that task.

well,
depends that which are the quality of the speakers utilized, the
environment and which is the ability to hear differences. :-)) For most
people is enough quality mp3 that does not mean it's the best, the
difference between an mp3 and a wav file I think it's recognizable by
equipment of average quality.
Certainly if there is some component that prevents the plant to hear
these differences is pointless to change the DAC
I will experiment with the internal DAC of the Touch but I think i will
use the coax output to connect an external DAC like the Musical Fidelity
VDAC that promises good performance at relatively low cost

 I'll wait until I can listen to the Touch myself, nevertheless, all
 information gathered around converges to one point : you will probably
 need a much better dac than the V-dac to outperform it. ;)

The modified VDAC 
output stage and power more parties .. you point to savings from a good
base. 
The DAC chip used in VDAC is good the rest can upgrade

 I design transducers so I can safely say, it doesn't matter how much you
 spend, or what the marketing department says, the very most expensive
 and best loudspeaker has orders of magnitude more distortion than does
 the DAC in the Touch.   ;-)
 
 That is my only point.

But that got to do!
You're comparing 2 different things. You can not compare the distortion
of the signal and the power .. :-O
Distortion then is not the only parameter on which you decide the
quality of a component hifi / hiend!
is important but not the only, if you're a designer you should know

 you can simulate the Squeezebox even the TOUCH by using the free
 software in the download section.  

Can you give me the exact link please?

the link you give me leads to this page,

Download Squeezebox™ Server

but I did not find any beta testers for the touch

sono impedito?:-))

[SlimDevices: Touch] technical info audiophile about SB Touch

2009-12-05 Thread perito industriale

Hello,
i turn to the technicians and designers of the apparatus, serebbe very
nice if we could clarify some of my questions because I think the
subject very interesting.
Any answers will be posted on other forums as Italians were no reports
of common interest, there is great excitement around music liquid!



I'd like to understand the quality of the program used as a player and,
above all, on what software rev ...

compete as a player is quality compared to PC player like Foobar 2000 +
driver on Vista or WASAPI Seven, or an iTunes on MAC?

What kind of HardDisck support and what capacity? 
They also support all USB HD 1TB?
