Is the gs-x the more nutral one?
How does one choose between the pre-amp and headphone section since there's no switch on the gs-x?
the GS-X has no selection, the poweramp must be turned off to switch to headphones. likewise the headphones must be unplugged to run only the poweramp. my poweramp has about a 30 minute warmup time and its a hassle to be turning it on and off, thats why i was excited about the Apache selection switch.
FWIW i talked to Ray about some points of confusion. the chasis are the same in the side extrussions only. the front/rear face plates and top/bottom plates are custom for each. i assumed it was an "off the shelf" chasis with a custom faceplate but thats not the case.
the preamp and headphone output does have seperate buffers. so when the preamp is selected the headphone circuit is shunted to ground, and vice versa. this accounts for the varying impedances and the unused inputs are all shunted to ground as well, this addresses Cheseberts questions.
FWIW i do prefer the seperate powersupply design, im not sure if it truely represents a sonic improvement but i assume that i does reduce the noisefloor, plus its much more convenient to place two mid size enclosures than to find a spot for one hulking chasis, also its much easier to get close to the wall socket with a 2 box design.
