FlacWavLoader with SoX SRC

For those who think WAV sounds better but like the convenience of a well tagged FLAC there is this little program by Mike Galusha.
It converts FLAC to WAV.
It writes the output to a folder but on systems with sufficient memory the file is cashed so memory playback too.
It calls your media player
The latest version also added SoX for resampling.

Sonata media player

If you think that dbPoweramp is one of the best rippers and format converter available and JRiver the best media player, Sonata it a media player to look for as it is an integrated version of  both dbPoweramp and JRiver.
It caters for classical music by supplying tags like genre, style, composer, work, conductor, orchestra, soloists, singers, period, instrument, etc.
They build their own proprietary classical database called SonataDB that now counts +40,000 albums tagged by musicologists and that incorporates hi-res covers art.

Ayon Skylla II


Manufacturers description:

Ayon Audio is pleased to introduce the superb Skylla II DAC featuring a fully balanced digital and analog design. In its digital section, four Burr-Brown PCM -1704K DACs are arrayed in a true differential dual mono configuration. The differential gain stage is composed of two 6H30 high-current tubes per channel. The Skylla II DAC features a vastly overrated, high capacity power supply for the 6H30 analog output stage with tube “bridge” rectification, choke coupling, three oversized power transformers, two for the analog and one for the digital section. The Skylla`s sound is rich and detailed, highly transparent and holographic, the resulting sound field representing an complete, realistic reproduction of the recording, a life-like mirror-image of the original performance. The Skylla II DAC provides audiophiles with a new, exalted level of digital playback experience, comparable only to the best available analog sources.

WAV vs FLAC


One of the many endless debates in computer audio is WAV vs FLAC.
Some people report an audible difference. Most of the time in favor of WAV.
Other says this is plain make belief, placebo, etc because when FLAC is converted back to WAV the result is bit identical.
Others argue that the processing power to convert FLAC to raw PCM is higher than in case of WAV so this might affect the timing (jitter).

An obvious downside of WAV is the lack of a tagging standard resulting in poor portability of the tags between media players / playback devices.
FLAC has a well-supported tagging schema.

From R14.1 on dbPoweramp has an option: uncompressed FLAC.
Now you have your uncompressed WAV with the tagging capabilities of FLAC.
Looks like the best of both worlds.
