Will the HP output and the line output work both at the same time or are the outputs switched?
The volume OUT is switched. That means, when you plug a headphone into the jack, any amp and loudspeakers connected to OUT will go quiet.
I have assembled, tuned and listened to the first production Giella today, number 001. And I am very, very, VERY pleased.
My previous reference was the prototype called Giella+. In the development process there was also a less expensive version, about 65% the cost of Giella+, which I thought was OK, but once I decided to push it to level 2, the benefits were so great that the original Giella design was abandoned. When I did the final layout of the board in August, I decided to optimize it for power delivery rather than regard it as mainly a preamp. And the result that I finally experienced today was really interesting.
Listening to Giella 001 through headphones is even better than I thought it would be - more powerful and with a sublime control and timing that the prototype doesn't quite have. Very addictive. I have so far not listened to any headphone amp that is anywhere near that sense of timing and musicality. I am so much looking forward to YOUR impressions of it!
The line out feature, however, was a bit better on the "Giella+" prototype. That one was frighteningly good as a volume control driving a power amp, but a little less capable of driving headphones directly. I figured it would be a compromise that I could tilt either way, and I decided to tilt it in favor of driving headphones. It turned out to work exactly as I had expected.
