The "analog" warmth of Soviet valves! New in box!! The SVP-01 is a valve preamplifier, developed for various uses, whether in recording studios or in the best Hi-Fi audio systems. One of the immediate advantages of this type of pre-amplification is the additional “heat” provided by the valves, which makes the difference between good and great, making any audio source sound better than before. The SVP-01 combines in its genesis the best of both worlds, that is: advanced electronic semiconductor technology, taking advantage of the most advanced technology currently available in this area, and “vintage” technology, via valves, based on the best tradition as original valves from the 70s are used directly from the former Soviet Union! This model allows you to directly reproduce the analog signal from records (vinyl) or other digital audio sources such as CD, DVD, MP3, MP4, or direct audio from systems IT solutions such as computers and audio cards for Digital DJing such as Serato or Traktor, substantially improving the quality and resolution of the output audio. The sound signal processed by the SVP-01 reveals dynamics and a natural timbre at the level instrumental and vocal, in the warm sound style of traditional vinyl! Its two valves incorporated into the SVP-1's beautiful chassis, they allow you to simultaneously process up to two audio sources such as 2x turntables or 2x CDs and even interleave them via the phono/line selector.
