A legend returns! Musical Fidelity sold almost 50,000 of their original X-10 Tube Buffer Stage and has finally brought it back to life. The new X-10v3 is based on the Musical Fidelity exclusive Mu-Vista (kW) tubes and is guaranteed to add the magic of tubes to any system without adding any significant noise or distortion. The new Mu-Vista tube is Musical Fidelity’s highest performance tube to date. It’s more linear and quieter, with better performance capabilities than either their highly regarded Nu-Vista or Tri-Vista tubes. The X-10v3 is a tube output stage that can be added to any system; perfect behind any digital player, in a tape monitor loop or between your preamp and amp. Turn your CD or any other affordable digital player into the tube-hybrid player of your dreams. Add it between your amp and preamp or into a processor or tape loop and hear every single source component come to life in a spectacular way. Once in place, you will hear an added level of richness, warmth and musicality previously attainable only with a tremendous investment in world-class tube gear. The $399 Musical Fidelity X-10v3 Tube Buffer Stage will be a very limited manufacturing run, so audition one in your system before they are history!

About the Mu-Vista tube:

Musical Fidelity's latest discovery, the 6112, is an ultra high performance twin triode that we call the mu-Vista. Originally, it was used by the US military for crucial low noise guidance and other missile functions. It is incredibly rugged and immune from microphony and other extraneous effects. Also, and we hope this attribute is never needed; it's immune from electro-magnetic pulse (EMP) which occurs when a nuclear bomb explodes! As you would expect, the mu-Vista is super tough, super quiet, ultra reliable, incredibly linear and absolutely predictable.

Musical Fidelity has not had a single Tri-Vistor 5703 tube fail anywhere in the world in any of their Tri-Vista products. Our tests show that the mu-Vista has similar levels of reliability, and why not? The tubes have been purchased direct from the US military and are genuine milspec, mil usage parts.

As far as we know, they have bought the vast majority of the world's stock of the amazing mu-Vista. It will form the basis of a number of limited edition products.

NOTE: The X-10v3 does not have a power switch on it and we have received numerous questions about whether or not to leave the X-10v3 powered on all the time. We recommend giving the X-10 at least a full minute to warm-up before turning on your amplifier and then leaving the X-10v3 on all the time. According to the X-10v3 owner's manual "This product has been designed so that it may be left on indefinitely, it may become warm to the touch - this is normal."
