Burson Buffers?


Does anyone have any experience with these? A company that does mods on cd players is sending me one to see if it will solve my lack of bass punch that I am experiencing with my recently purchased Cambridge 840c.
As usual any input is appreciated.
Thanks

A friend and I compared the Burson to a Goldpoint stepped attenuator, using a 840C and Pass Monoblocks.

Even though the goldpoint was built with quality parts(silver wire, copper RCA jacks), the Burson had better transparency, dynamics, and extension on both ends. I would highly recommend it.

I can find out which value Goldpoint later this week, but we used the single ended input on a pair of Aleph 2's.
