No, we are Audiophiles. the better quality the music is the better. We have a show room in our house to promote my husbands business. He designs and builds Home audio, theater, and High Grade car audio systems, also competition grade car audio systems. 2 years in a row his designs have won the world finals in best in show, highest DBs, and best in show for SQ. (sound quality)

The Constantine+ is a hand made DAC and is the best on the market. We don't use MP3s or CDs we use a computer with the DAC and play FLAC files. there is no brick wall filter on FLAC like there is on CDs and MP3s. frankly MP3s are the worst in quality I dont know why we even use them!

Best way to put it with FLAC... studio quality sound.
