  Descriere Produs

  • Audio Research Reference Phono 2 is a fully balanced design with an input circuit that allows its RCA inputs to operate in a balanced configuration without requiring an inverter. Audio Research Reference Phono 2 shares the same tube complement as the Audio Research Reference 3 and Audio Research Reference 5 line-stages, and also the Audio Research Reference CD8 compact disc player; four 6H30s in the gain stage with a 6550C and 6H30 in the power supply. The Audio Research Reference Phono 2 also features the same basic analog stage as its acclaimed siblings. Rather than using a step-up transformer, special high-gain, extremely low-noise FETs are used in the high-gain section. This approach is costlier than using a transformer, but it is well worth it for the dramatic increase in performance. There are new, proprietary capacitors throughout, the transformers are new, and there are eleven stages of power supply regulation. Connections on the rear panel include two sets of RCA inputs with ground post, XLR and RCA outputs, and a 20A IEC connector. Sonically, the performance of the Audio Research Reference Phono 2 is in another world – it is so transparent and vivid in its presentation, and just sounds so musically beautiful, that it will take your breath away. There is a master tape-like quality in which instruments stand in bold relief before a black background, with the space of the recording environment reproduced with uncanny realism. Saying that it achieves 'new levels of resolution and dynamics' sounds clichéd, but these are authentic attributes. The Audio Research Reference Phono 2 truly provides a clearer connection to the music. And, in a world filled with remarkable turntables, tone arms and phono cartridges, the not-inexpensive Audio Research Reference Phono 2 is a bargain relative to its exalted performance. More than twenty-seven years after the introduction of the compact disc, we continue to discover how much wonderful musical information is buried in the grooves of our beloved vinyl collections. Hear for yourself why this is truly the golden age of analog playback, and call your Audio Research dealer to audition the Audio Research Reference Phono 2. It will be a breathtaking experience.
