These do impact the performance. You should verify this.

A quality low ESR cap array ( Epcos Sikorel/Rifa) IMO still performs better then a plain battery.

Hint: You might also try a Bybee in the line.

Cheers
I know that the wire, switches, etc have impedance values (usually low) BUT it is not frequency dependent as a capacitor is! I found that even using Sikorel that the sound slowed down & suffered in the dynamics department.

Please don't get into Quantum noise blah, blah with those Bybees - it's more than I can bear.

Soundcheck, first thanks for your mod and your work.

I want to apply your ethernet mod, but it`s impossible for me to connect without wlan. The only alternative would be to connect with devolo dlan products.

What do you think about this? I can imagine that internet via electricity produces a lot of noise.
Has anyone experience with dlan and hifi?

Cheers

Default modifications to the squeezebox touch

noted the software downloads, etc required to improve the performance of the touch. Unfortunately now running windows. Running Squeezebox Server on a NAS: Infrant / Netgear Ready Nas NV+.

Any ideas as to what files to install to improve the performance as described by you for a windows system? Instructions would be appreciated as well.

Thanks in advance.

Soundcheck, thanks for the tips on modifying the Touch.

I have noticed a huge improvement after getting rid of the WLAN and unplugging the front touch panel.

Previously I was running strictly off the USB hard drive but I am surprised by using the Server to output uncompressed PCM stream to the Touch made a noticeable difference in sound quality in terms of the dynamics.

I would highly recommend trying the soft mod out and also removing the front panel is truly worth the effort.

If it matters I was running Squeezecenter within the Touch using a super low power Solid State Drive off a linear power supply of course.

The next thing I would like to do is probably try the Battery


Cheers,

Hi.

All my modifications can be applied from any OS. I described how to do it at the blog.
The main challenge is to get logged in into the Touch and to transfer a file to it.
In principle you just need an SSH application to transfer my config-files from Windows/OSX/Linux to the Touch-Linux.


Please, let me know if my instructions are unclear or faulty.

Cheers

Hi.

I don't have any experience with powerlans.

This is what I think about it:

1. The mains-cabling is usually not shielded. You'll get a nice antenna
by running MHZ signals over it.
2. The powerlan adapters need to be on the same mains-phase or you need
to introduce a so called phase-coupler.
3. And yes -- you are right. We don't want more garbage on the mains and
ground then we already got.
4. The bandwidth of powerlan is still kind of low. I am sure that the data
will face a lot of "resistance" from point A to B. I am sure its bandwitdh will also vary a lot. This would make it not really the ideal solution for continuous media-streaming.

Though I think powerlan could still be better and stable then a WLAN connection in terms of bandwidth-variations - it's just the lesser of two evils.


Advise: You should consider that meanwhile TV-sets etc. also require ethernet connections. Sooner or later it is IMO a must to have at least GBIT-lan in the living room. Those IP networks need a lot of headroom to perfom best. I introduced CAT7/CAT6a wiring. Do it right, you'll do it once.

Cheers

Default removing the coupling caps

I am getting ready to open up my Touch to do the hardware mods.
Where are the coupling caps for the audio output that need to be bypassed?
Do these caps need to be replaced externally?

thanks

Just could just short-circuit the caps.

According to John Svensson - he is running the device that way - the Dac chip can be DC coupled.
No need for an extra cap. You might look up the DAC datasheet.

Don't blame me if you smoke that device!! It's on your own risk.

I havn't done that mod by myself.

Good luck.

Hi folks.


I added a new tweak to the blog.


Chapter 1.4. Alsa Buffer Size Reduction


Give it a try. Highly recommended!


Cheers
