To ifi audio: My gears are 1 USB-Coaxial interface (5V-9V), 1 raspberry pi (5V) and 1 movie player (12V). They all have a quite decent switching power supply and I would upgrade them. I DO NOT need to switch them on at the same time. 1. How much improvement in term of percentage is the new DC...

  Hmm...the picoreplayer is somehow relatively hard to setup up but have you given RaspyFi a try?   I am not sure about zone 2, do you mean have the 2nd RPi and play music stored in a common storage like NAS?

If money is not a problem, how about SSD? there is 1TB available.

My guess is should be worse, due to moving disks generating noise.

Wow, I am afraid I could hardly agree with any of you saying that the TE8802 (Async) is somewhat the same sound quality as the old TE7022 (Sync).   The TE8802 is certainly a different beast and way better than the TE7022 in all aspect.   I have the 10SE and the DI-V1, both have the TE7022...

Before I use Raspyfi, I use Picoplayer and that requires a network storage for music. Therefore, I start with a PC and a Wifi router. all of them are connected with Ethernet Cables. Later, I found that all of those PC components have impact, mostly negative, to the sound quality. At last, I...

  So, what did you use as source? Did you compare them?

  Welcome to the party. I am also using RaspyFi 1.0 too but on DI-V2. Please check if you have the occasional "Zap" sound like I am having. It might be better if your music is stored in a USB memory drive directly attached the RPi.

  Yes, I agree with you. A MPD client is a must consider the Web Interface misses some features.   It seems not it is because of the lack of CPU power because some users told me it is fully compatible with XMOS based USB DAC up to 24/192. Besides, I run "top" to watch the CPU usage and it...

  No, it is a different beast. Before I wrote this thread, I compared Picoreplayer with JRiver media center in a Lenovo Notebook / PC. Sound quality is clearly superior in Picoreplayer.   You could bypass much of the unnecessary processes for sound generation in Windows by WASAPI but:   1...

  Interestingly, I also tried squeezeplug in the very beginning and found that it is not compatible with my USB DAC, though it might be the lack of knowledge to tune it. Moreover, if I install LMS into the same RPi, it is too unresponsive because of a lack of horsepower.   Since you have a...

  Thanks for your support. As you might have overlooked, I now found RaspyFi v1.0 is even better both in term of the ease of setup and sound quality. Please visit this thread:   http://www.head-fi.org/t/681593/cas-source-raspberry-pi-picoreplayer-raspyfi

Preface: I have been using Picoreplayer for a while. It is a great piece of software and it is a good CAS source compared with PC.   My Introduction to Picoplayer could be found here: http://www.head-fi.org/t/674236/cas-source-squeezebox-touch-replacement-raspberry-pi-picoplayer  ...

  Yes, since all 2.5" USB external hard disks are USB powered.

  Yes, Samba should work but not tested yet.   USB storage directly attached to Raspberry Pi is tested okay, but beware that I tried two different 2.5" USB external hard disk with no success, perhaps not enough power to drive.

  Most of the NAS support LMS, like Qnap, Snology.   Please also test RasyFi v1.0 too.

Everyone using Raspberry Pi, good news!!!   A local forum user impressed with my Picoreplayer suggestion and he just counter suggested to try a new OS, the RaspyFi v1.0.   Quick tested and found it is far more easy to setup and the sound quality is better. You could play music via USB /...

  Yes and No.   Yes, you could install the Logitech Media Server in your NAS and play music from NAS.   No, you could not play music via Pi's USB port with Picoreplayer.

  Yes, it is a change of source because it is now Pi controls your DAC. PC will just act as a place to store the Music.   It might be because PC has too much components and therefore a noisy background. Also, the OS in picoreplayer is simple and little non-essential processes are running...

  No, one of the beauties is its simplicity, well, sort of. You don't need to code anything with a Wireless / Wired router.   Please refer to the first page for an updated simple setup procedure.   It depends on which kind of USB chip in your DAC, if it is TE8802 based, you could use the exact...

  What do you think in terms of sound quality in this version compared with others?

  Yes, it is very seriously exceptionally good and yet CHEAP!! I am sure it is the best upgrade for years since I play CAS. Welcome to the party!!   Honestly, I am little disappointed for such little people would like to try this. Is there something wrong with my suggestion?? I am really a...

I did not play with settings and versions for a while but to enjoy the music played via picoplayer. I would like to share my latest setup and experience with you.   1. I am using "willem1" to play my majority 16/44.1 music, it causes the least problem and sounds best amongst all versions.  ...
