Steve Guttenberg, CNET: “The sound is nothing short of astonishing: the SoundSommeliers disappear as sources of sound and project a stereo image that extends well beyond the actual locations of the speakers. As I continued to listen long after the period required to write a review, there was something about the sound that made me come back again and again. I was falling in love with these speakers, and that's rare for a guy who writes more than 100 reviews a year!”

Designed for music lovers with little computer skills, the new SONATA Music Server from DigiBit is a sophisticated software specially designed to handle classical music (and any other genre). The SONATA allows you to select your preferred music the way you want: by genre, period, style, instrument, composer, work, conductor, orchestra, soloists, singers, music label, etc. This will allow users to rediscover in seconds many forgotten records in their music library. For example, you will be able to ask the SONATA to show all the records of Romantic music for Piano by Chopin placed by Claudio Arrau or the Opera records with Placido Domingo conducted by George Solti or the Jazz records where Charlie Haden plays Latin music. Our proprietary and unique SonataDB and the GD3 ( database for classical music provide users access to over 40,000 classical CDs, with exhaustive information of each CD saved in 18 fields that, with the help of the also unique "Views" menus, will allow users to perform unique searches by filtering the music library using the most sophisticated combinations as stated above. Covert art is available in hi-res 1000x1000 and 1400x1400 format for most classical CDs and above 500x500 for the rest of the genres.

The top of class CD ripper built-in provides access to metadata from 4 databases (GD3, SonataDB, FreeDB and MusicBrainz) thus, achieving superior metadata retrievals results.

Simple menus, multilanguage and multitouch screen support and a very intuitive and easy-to-use GUI makes the learning curve almost inexistent. Selection and searches can't be easier as the user will always be viewing the covers of the albums/tracks sorted by the criteria he/she had previously chosen.
