I do think SPDIF vs. USB discussions won't lead anywhere. It's always a matter of how every single device respectively system is implemented.

There are numerous factors which can turn results into one or another direction. Every change of a test scenario can lead to a different conclusion.
There are good USB implementations and meanwhile there are also rather good SPDIF implementations.

I do have the impression that the recent "competetion" of USB vs. SPDIF causes some promising progress in that area.


When it comes to features such as number of channels, bitdepth, sample rates, USB must be considered the much better and far more flexible interface.

I'd phrase it differently.

All serious digital-audio transmission via USB or SPDIF need at least a highest quality reclocker and serious noise supression resp. source isolation on the receiver side in place.
By having this in place SPDIF vs. USB shouldn't make any difference anymore.
(Of course it's not that easy - many manufacturers claim to have above measures in place and still the results are all but satisfcatory - "in audiophile terms" )


The DI V2 would be a really good device if

a. SPDIF vs. USB inputs wouldn't make any difference anymore (to be confirmed)
b. any of the known source/transport choices and related optimzations wouldn't have any impact on either SPDIF or USB anymore. (to be confirmed)
(c. If the device would support generic USB drivers )


Cheers

Hello Soundcheck,
Any news on the TT4.0 version which won't conflict with the Triode plugin?

1. Since the intro of the DI I can't really motivate myself to finish up TT40.
With the intro of the reclocker and source isolation all those mods
become somewhat less relevant.
Tweaking the transport/source, I consider the wrong way anyhow.
Doing it can't be more then a temporary workaround.
You'll never get the source under control.

2. and I neither intend to feed Triode with even more of my ideas/solutions,
which he will implement without talking to me about it, nor I'll make my
toolbox compatible to his stuff.


My current focus is on getting away from the Touch anyhow. This box is just too inflexible. Though for the time being it still works nice in my setup.

I already have some alternatives. I could also live with the iPad feeding the DI via iPeng player.

Projects like the Raspberry PI as audio player I do also consider very promising.


But let see. Perhaps I can motivate myself to finish TT40 for the coming (northern hemisphere) audio season

Dear Soundcheck,

Thank you for developing the TT2.0&TT3.0. You developments had made the squeezebox touch a lot more enjoyable. I guess every gadget has its life cycle. Perhaps squeezebox's may come to an end soon. I am sure everyone on the forum would love to hear from you on your latest findings and tweaks. Please continue to share your tweaks with us, whether it is your iPad feeding the DI or anything else.

Best regards,

Warpeon

Hi everybody,

i´m interested in how you guys are powering up your SBT.
I´m using a diy linearregulator based around UI-Transformer
mur820 bridge, 10000 panasonic ´lytic and then a regulator
based on lt1085 as described in its data sheet.

Plans for the future are changing the transfo and rect. for some
accu like SLA or LiPo plus charging device, but i have no circuit
(for charger) will be the best. Read about the LiPo-Charger being
quite complicated.

Greetings ulf

Hi folks.

Here's an interesting review: W4S Music Server.

The W4S music server (2.5k$!!) gets reviewed and compared to a MAC+Amarra and a TT30 tweaked Touch with Welbourne Labs PSU.

The W4S server runs a commercial Vortexbox license btw..

I do not really agree to the business case that Joel (the author) is making
up:

I wouldn't put a MAC on the balance sheet (every old PC can be used as a server) , nor I'd pay for 300$ for a PS. Let's not argue about a 2TB disk. On my balance sheet I 'd end up at around 500-600$ on the SBT side.

I could imagine that something like a Rasberry Pi based installation in conjunction with an USB DAC can get the business case scenario down towards on overall effort of 200$ vs. 2.5k.

Bottom line.

An SBT with with a little tweaking and TT3.0 + iPeng seems to be pretty competetive in the music server market. (Even without TT40 and TTserver). ( What else is new!!? )

It's also interesting to read that he puts a MAC + Amarra at the bottom of the rankings.

The author also pretty well points out the weaknesses of an MPD (MPad) setup, which come with the Vortexbox.
That's what I'm saying since years. MPD got stuck around 2007/8. It remains in maintenance mode since then.


Another area is tagging and cover art handling which is kind of limited on the Vortexbox thus W4S server. (Nothing new so far.)

Yep. Even if I'm using Linux on my audio machines, I won't get around using dbPoweramp and MP3Tag on my Windows installation to get my CDs ripped and the tags nicely and consistently edited resp. formatted.



Enjoy.

Cheers

Hi folks.

Just to leak some info:

I've been in close contact to the iPeng guys. I proposed some time ago to have a look at native <=24/96 support for the iPad player app of iPeng.

The other day an invitation hit my mailbox to betatest a new iPeng version.

I couldn't say no to it.

Guess what!?!?


Now I'm happily streaming 24/96 via iPad, which is connected via Camera Connnection Kit to my Audio GD-DI VI.
That's basically making the Touch obsolete.

The main issue with the camera connection kit is, that you can't charge the iPad as you'd do with a normal dock.
A dock that would provide USB with CCK functionality and iPAd charging would be great.

Another limitation is that you might need a USB Hub in the link to connect your DAC - even if your DAC is externally powered.

The release date for this feature is not yet fixed. They still have to work on some minor issues.

Cheers

This does not surprise me. I got quite exceted about the SBT for a while, but upon going back to my PC setup, I found the PC sounded much better.
