There are many reports on internet ( e.g. Jplay mini 5.1 vs. JRiver 18 with Jplay 5.1 - Page 2 , there are many others) where the blind test results contrast with the original confidence.

Do whatever you want to, just do not bash blind testing if you just do not want to use it.

For me that whole process is big fun and is what I like most of High End Audio.

I do the same for all my DIY audio gear (DAC, pre, amp etc), part by part, wire by wire. Voicing is a very difficult, combinational,self-developed procedure...

By the way, the past few days i am trying audiophile linux (AudioPhile Linux | Audio Perfection on Linux). I am afraid that when combined with Deadbeef and Jack (Playing audio | AudioPhile Linux) it sounds better than any Windows player...

You can easily try it by creating a live cd or usb.

I installed windows 8, mac os 10.6, and the above mentioned linux (audiophile dist + jack + deadbeaf) on the same computer and tested some of the available bit perfect audio softwares. The results of my test are:

1. Pureplayer (win)
2. Amarra (mac)
3. Pure Music (mac)
4. Audirvana (mac)
5. Jplay (win)
6. Deadbeaf (lin)
6. Jie extreme player (win)

I am using an m2tech hiface converter and drivers may have influenced the test on linux.
Pureplayer I enjoyed the most and not by a small margin. I can't wait to start the next tune. It is great, thanks for your effort. I also made a small change to the source to be able to play high resolution files.

Interesting stuff npetralias! I have seen this site before but never gave it a good read. Al that computer related stuff makes me dizzy now and then…..

At this moment I am using a Hifidelio music server (also Linux) with an external Buffalo 3 DAC. I have tweaked the Hifidelio to some point now and have some ideas to make it better still. But I also consider building a dedicated PC based music server. It’s hard to decide where to start with the best possible sound quality in mind. But Audiophile Linux sure looks interesting!

Jack is used for audio creation (DAW), it is a framework for low/zero latency linking and synchronization of various audio applications. As a result it runs at a single samplerate, your music will be resampled (or refused to play, depending on the playback application).

Just configure deadbeef to use alsa output directly (plughw:YOUR_CARD_NAME), jack just adds unnecessary complexity.

Fantastic!
With m2tech/m2techII i totally agree, but when using a better (IMHO) interface like CM6631, linux sounds better (never tried MAC).

You just modified the c code (flacplay and flacplay_wasapi), correct?

Only the c code for flacplay_wasapi as this was the only one with the issue. What converter is using CM6631? I tested the hiface 1 (modified to battery power) against more expensive converters and I like it more, there is something magic about it. Of course, this is just my opinion and when I compare I may have different priorities than others. I do not care much about the instruments resolution or dynamics but more about my behavior during and after the song (if I feel the need to turn volume down or up during the play, how involved I feel or the urge to play another song or close it )

Yes i was also using a modified m2tech many years now, until i tried this

New CM6631 USB to Coaxial Optical SPDIF I2S Convertor for DAC w PSU Transfor | eBay

There are cheaper versions on ebay but this is the best. PSU and buffer included. I2S output too. Just get rid of the SPDIF output transformer and enjoy...

Did that ebay converter come with CM6631A chip? Sometimes they update to the latest components.
