In the finest tradition of amplifying music from vinyl we proudly introduce the BC709 and the BC707 phonostages. From the outside, they look the same and have the same features and functions. The difference, and it s a big difference, is on the inside.

The BC709    

The BC709, the first product that incorporates our new FC technology, supplies all the features and functionality to provide excellent vinyl reproduction for the vast majority of systems. It offers the smooth, rich and round full presentation that only vinyl can supply. Matched with a quality turntable and cartridge, the BC709 will perform flawlessly with a wide variety of MM and MC cartridges. The external loading feature was designed to easily adjust the loading to suit your favorite MC cartridge. With the optional adjustable loading plug, the user can adjust the loading to an infinite degree while the music is playing.

The BC707  

We reserved the internal real estate for the serious vinyl advocate that demands more than the BC709. The BC707 is a upgraded version of the BC709. Its power supply is one of our trademark upgrades. With filtering capacitance approaching 700,000uF, the BC707 is stable enough to handle the most demanding musical passages effortlessly.
