If you have been wanting to hear the sound of vacuum tubes in your home hifi, the Mars Buffer will do the trick.

Priced at R4 900 it is a useful device with many applications.

from the web:

"A tube buffer is basically a passive pre that allows you to introduce a tube sound to the signal and can be used in line with a solid state preamp either before or after that preamp. So if you are attached to a certain solid state device that gives gain but want to try adding tubes, a tube buffer allows you to experiment."

Our design uses a minimum of components for maximum transparency and a common mode rejection power supply for very low noise floor.
