ARC har nettopp lansert et nytt phonotrinn; PH7.
Det skal visst erstatte REF. Phono. og prisen blir ca $7K.
Description
ARC has just introduced the PH7 Phono Stage Preamplifier. In spite of not appointing it as a reference product it will substitute the REF Phono that is already out of production. The PH7 is an advancement over the REF Phono.
The PH7 take advantage of recent technology developed for products like the REF3 and CD7 and uses an all vacuum tube audio stage with four 6922 twin triodes. Regulation of the power supply is also vacuum tube using three 6H30.
Output coupling capacitors are the advanced types and costly, designed for ARC, with power supply energy storage more than three times that of the PH5. Circuit board materials, power transformer and other components have been criteriously selected to reach phono performance to a previously unachievable level.
The PH7 has 57.5 dB overall gain (same as PH5) and has one pair of single ended inputs and outputs. Full remote control is provided for all functions. The display is an easily readable front panel vacuum fluorescent like the REF3. It shows all selected functions including loading (47K, 1K, 500, 200, 100 Ohm), as well as accumulated hours of operation. Display intensity can be adjusted to one of eight levels, plus off.
The PH5 has won renown for its inspired musicality, precise tonal balance and realistic dynamics. The PH7 dramatically improves upon these virtues and more. Soundstage dimension is scaled up in width and depth, with even more solid image specificity. Tonal shadings and micro dynamics are much more vivid, thanks to extra power supply muscle and a lower noise floor. Perceived frequency extension is much improved, with highs silky yet vivid, while deep bass notes are carved out with slam and real tonal definition
