Общаюсь с одним челом по имени Dan Wright ( он отсюда )..
Он тоже начал задумываться о транспортах на базе Оппо 103... вот что пишет :

As to the linear supply, external is really the only way to do it. I tried to build an internal unit for the player, but there is just too much current to one of the voltages and it generated too much heat.

I wonder if anything can be done with the actual digital out signal. I heard that in the 103 at least, it is just TTL, not even proper SPDIF and as such is HORRIBLE for dig. out signal. A couple of chips and simple cook-book SPDIF conversion circuit should make a big difference. I have simply not taken the time to do it. In terms of improving the 103 as a transport, I understand that converting TTL to an actual 75 ohm SPDIF out would be the right place to start.

Руслан и Владимир, что думаете по этому поводу?
