While I don't have a 775 or 785, I do
have the T175, which is the cousin to those units. Over in this thread
, you can see that were having the popping issues as well. I spoke with Bob Moran on the phone Friday, and believe it or not, they're having trouble replicating our problems in the shop.
Please, please, please
, if anyone is having any of these issues, call or email Bob. Give him as much info as possible. When does it pop,cable types and lengths, other equipment, etc.
I've already had my 175 in the shop, and it has both board fixes, and up-to-date firmware. And
it still pops. To say this is all frustrating would be an understatement, to say the least.
On a side note, has anyone here successfully passed a 192k signal through their unit via HDMI? SACD playback from a PS3 should do this. None of our 175s will, and according to Bob, they should. Neither my PS3 or my Pioneer DV79 can send 192k to it. Chalk that one up on the problem board as well...
As to when my unit pops, if a digital signal is present for a while(10-15min with no changes) it will pop when the input is changed, digital sample rate changes(cable box switching channels), or even simply muting the unit. Pops on mute, and
unmute. Go figure. After pressing mute 6-8 times, the popping goes away for awhile. But it comes back. It always does...
