    Delivered very quickly-5 days at the place of residence in the nearest Pyaterochka.
    The performance is very good and quality. Body is thick metal. In fact, I did not check.
    Will be the replacement of the regular phono stage Arcturus 006. In fact, the manufacturer does not indicate that it is Fono or phono stage. On all related papers it is written that it is a preamp-aligner RIAA. Let’s see how he equates. After the tests, I’ll unsign.

  23. Shopper

    Quickly qualitatively and corresponds to the description. Included power supply for 12 volts. Body metal. Works well. Sound-well, it just strengthens. Like it must be. So I think there’s another preamp to take for the test. The board size is 90/60mm. Height probably up to 1,5 cm boards with details. It’s if anyone gets ready. Delivered the courier well, almost without a day week. How fast. Pre-messages were written in Wyber and called. I liked it in general.
