To celebrate our 21st anniversary, we are introducing the limited "21" series of products. We are proud to introduce Phono-21 phono preamplifiers (mm and mc versions) and Contour-21, an audio buffer with a twist. Phono-21mm and Phono-21mc Phono-21mm and Phono-21mc are phono-preamplifiers based on the successfull Phono-1 MkII preamplifier.  Phono-21mm is optimized to work with most Moving Magnet (MM) cartridges, while Phono-21mc will complete an analog setup based on a Moving Coil (MC) cartridge.  If you own any Ortofon 2M,  Audio-Technica, Rega or Shure MM cartridges, you just have to give Phono-21mm a listen. High Output MC cartridges (HOMC) are also supported with this little gem of a preamp (we love how Dynavector sounds). Phono-2mc will allow you to get the best out of your Low Output MC (LOMC) cartridges regardless of their price. Denon, Lyra, Clearaudio and others will love unrestrained dynamics without the need to use a step-up transformer.  Contour-21 Contour-21 is a more flexible version of our Contour audio buffer. The principle of operation is the same but the new front control makes it possible to turn off the circuit for enhanced spacial resolution (turn the control knob all the way to the left, until a gentle "click" is heard). The control knob is used to modify the level of channel separation by adjusting the control to optimize sound to your liking. Vista Audio - a brand of VertyTechnologies, Inc..
