Bellari PA550 3-Channel Phono Preamp and Headphone Amp with RIAA Equalization Curve The PA550 audio Pre Amplifier has three selectable stereo inputs: phonograph, RCA and 3.5mm (1/8") jack for phones, tablets or other. It features a very powerful headphone amplifier so it can be used as a standalone headphone amp. Designed to have the highest level of sound quality, whether you are using it as a headphone amp or sending music to your amplifier. At every design stage we spent a considerable amount of time focused on one thing, sound quality.
The PA550 tone is full bodied, letting you know right away that all frequencies are covered and nothing is masked. It never gives you the impression that it is making the treble too shimmery, or that the bass response has been overly fluffed up.
