- Tubes seem to pick up noise more easily, and I'm surrounded by computers and phones and tablets with cellular radios all the time. When I spent some time with a couple of tube amps at home, I had problems with my most sensitive and detailed headphones — the Beyer T90 — having audible noise from both tube amps that they didn't get with two solid-state amps in the exact same setup. And from what everyone says, the SR-009 are particularly sensitive and detailed.
Never had so many noise problems as with my KGSS and the 009.
It is so sensitive that even the flickering of the MacbookPro display or a Iphone/ipad nearby can be easily heard.
With the Stax Amps there will be no noise at all. Its going to be interesting how a BHSE will act. CANT WAIT(2 1/2 years now waiting) to find out!
The DAC is a ESOTERIC D02 and cabling the good stuff from Wireworld, so that could not be the source.
I have a very quiet surrounding which may a reason that i´m more sensitive in hearing than others. My Summit X Electrostatic Loudspeaker for example have a noise problem on the active sub amplification, very subtile, that most of the other Martin Logan Summit owners haven't recognized.
---The Martin Logan ReQuest Speaker with the same Amp, a Lyngdorf TDAI2200, did not have any noise.
