Same condition like before unless mentioned below.
--> Silver Gain Switching Capability: Everyone, yes, only Geek Pulse IGG backers has: 3 gain settings for Headphone.
For Big Can: 7Vrms
For IEM: 1.8Vrms
And the noise floor of Big Can is 8uV. IEM is 2.8uV or so... (we are approaching the testing limit of AP)
Trust me, this is NOT easy. Especially considering we have different gain settings with in one headphone output amp.
And we have quite a lot of high speed digital stuff running within 5 inches.
THD+N of these new output settings? Still amazing.
7V setting (load at 300 Ohm)
1.8V setting (load at 16Ohm and 32Ohm, results are very similar)
So every big dog and little cat has its own places to stay. Geek Pulse could work with 99% of the headphone, we believe. (Sorry Stax users, we are not there)
Enjoy!
Then everybody, has a nice weekend. I will post the Geek Pulse X/S!!! With Femto and Amp.
Stay tuned.
One minor incident we found today, one Amp on right balanced output positive phase stage in Geek Pulse X's board, two pints of the foot print got strangely reversed by CAD software. So we need to jump wire to get the things right. Don't worry, we caught that. It will cause the verification plus new board for two to three days. We will try our best to catch up the same schedule as plan in other places. Just FYI.
Cheers,
Larry
