The FLAC file is a lossless file format, which can have a higher resolution and frequency range than the CD quality, depending on the initial format. This version offers perfect stereo (and even multichannel) quality for a living room sound set-up. Almost every modern computer is capable of playing these files. For extra quality, external DA (digital to analogue) converters may be used.
These are connected to the computer by USB, Firewire or another connections. Primephonic offers FLAC files up to 24 bit, with varying sample rates, ranging from 44.1 up to 192 kHz. This means that the sound quality can exceed that of the CD in means of dynamic depth and accuracy.
