SPL Phonos (Silver)

The RIAA filter is designed after Douglas Self. With up to 70 dB gain for MC cartridges and 51 dB gain for MM cartridges Phonos belongs to the most powerful phono preamplifiers.

The technical basis of all Professional Fidelity units is our proprietory 120 V Rail Technology, which we also call VOLTAiR technology. The name makes reference to the unequalled high voltage of 120 V (+/-60 V DC) and the huge dynamic range of over 140 dB that goes with it.

Available in Black, Red or Silver.
