The 6SN7 driver stage has enriched the musical performance of the Be Bamp. The bass weight is excellent, mid-range texture is extended and sound stage depth dimensional . Treble is controlled, detailed and mellow. Cymbals are naturally rendered and sibilance well controlled.
This remote driver stage is an improvement over the 6N1p stage (see other blog entries). Some may prefer the original driver stage to this with its brighter top end and crisp mid-range. The natural musical qualities of SE UL tubes amps is evident with the combination of this 6SN7 driver stage and the KT120 based Be Bamp.
For more technical information about the 6SN7 remote driver stage and Be Bamp see entries below.
Having the flexibility to change driver stages allows many different types of valves to use with the Be Bamp KT120 power section. The original 6N1P drivers stage can easily be unplugged and other suitable drivers stages plugged in. The power amp does not have to be turned off but the amp is placed in stand-by.
This stage is based on the 6SN7 twin triode valve. It is an extremely popular valve used by audio craftsman. The valve sits atop and a small metal enclosure. The base is sprayed with an epoxy enamel paint and the finish is hammered copper. Once again Russian military paper, foil and oil inter-stage and low ESR capacitors are used.
There is no hook-up wire or PCBs. used and once more component-2-component wiring is employed. The driver stage is compact and attractive and brings a whole new sound scape to the Be Bamp.
