Ok, good! I am powering my Strato S with a FARAD Super10, which made a huge difference, and finally brought the video quality up to ATV-X standards, perhaps a bit better.
I am curious to hear how the K compares to the Strato you had before, powered by a FARAD.
I am using FARAD for all my players except the Apple TV which is a Cinemike Apple TV.
The best sounding audio is from my el cheapo UOOGOS AMB 6Plus Chinese movie player.
The Strato V also sounded much better with the FARAD and I expect the K to sound as good also.
The video - I am told and have observed is unaffected if your projector is Digital such as a DLP - it makes a impact on analog projectors such as LCOS.
