Newbee question. Can I build a Gilmore Current-domain amp for the low bias Stax SR-X Mark 3? The 250 volt bias is easy. Can I use a +-250 volt power supply to keep within the 500 volt max swing? Would some of the component values need to be changed to accomidate the lower rail voltage?
Lowering the volts will means more transformer choices become available.
If I may, a final question. I am using the SRD-7 transformer on an old transistor dynaco amp. I am not satisfied with the sound. My reference systems is a Fisher 500C tube amp powering a set of Klipshcorns. My goal is to have equal fidelity whither I am listening to the speakers or headphones.
Will the improvement be worth it or are the old Stax cans just not up to the challenge? I know you have moved up to the Omega's.
If it is a stereo 80 or worse yet a stereo 120 then i'm not
suprised as to how it sounds. If its a stereo 400 it should
sound fairly decent.
Hook it up to your tube amp. If you still don't like the sound
then quit. At some point the old low bias headphones are
not worth the trouble. On my tube amp they still sound
very good even though the earpads are about toasted.
