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:
Recently, RaspyFi v1.0 is out. Before v1.0, I have tried the previous RC2. Sadly, it did not support WAV format and so I had to let it go. Thanks to a local forum user's advice, he suggested to try RaspyFi v1.0 if anyone thinks Picoreplayer is good. So I give it a try, is it really that good?
Equipment & Connection:
1. Raspberry Pi (256MB old version) -> DIY USB cable -> Audio-gd DI-V2 (Aysnc USB/SPDIF converter) -> 75ohm BNC-BNC connector -> Audio-gd NFB-10SE (DAC) -> ZY Balanced headphone cable -> Senneisher HD650
2. WAV files stored in a Sandisk 4G USB stick
Picoreplayer: (This following settings are deemed the best)
1. Logitech Media Server is installed in a Lenovo notebook.
2. USB stick is inserted into the notebook's USB port
3. Volume set to 100%
4. Auto WAV to FLAC streaming (flac/sox) is disabled
1. USB stick is inserted into the Raspberry Pi
2. Voulme set to 100%
Before I talked about the results, I have to admit that the installation of RaspyFi is extremely easy, just burn the image into a SD card, connect every hardware together, boot up and ready to play music.
Soundstage: RaspyFi wins, it is clearly that the soundstage is larger
Clarity: RaspyFi also wins, the music is even clearer, but the vocal seems a step backward
Separation: RaspyFi wins again, the background music is more 3D and come from different places
I strongly suggest to try the RaspyFi v1.0 if you already had a Raspberry Pi. If Picoreplayer is good, RaspyFi is even better.
Tonight, I compared USB stick with Network share.
1. WAV file stored in the Sandisk 4G USB stick
1. Raspberry Pi directly connected to a Notebook via Ethernet cable
2. WAV file stored in a 2.5" external hard disk connected via USB in the notebook
3. Notebook's OS is Windows 7
USB stick wins, clearer music.
1. Occasion "zap" sound like Picoreplayer (must be due to my USB/SPDIF converter compatibility)
2. Cannot play 24/96 music, constantly "pop" sound in the background. Did not test 24/192 yet. (must be due to my USB/SPDIF converter compatibility)
3. Some Chinese characters shows properly while some are not (May not concern you at all)
4. Raspberry Pi do not have enough power to drive USB powered 2.5" USB hard disk
Please compare and give comment.
