I too have an 8260. It works...sort of. I bought is second hand from a fellow A'gon member. It never had a problem...until I stuck in MFSL Patricia Barber...Then it was as if this disc unleashed all the ERROR demons from the player. I let a friend use the same disc. He bought his brandy new and never had a problem..until he played that very same CD. Now, his player is in worse shape than mine.
Mine only chokes occasionally now. Very strange. I can live with it for now, I think it sounds incredible and works for me, but eventually I want to move on. Ill keep the player and have some fun doing my own mods.Warranty is toast unless I try to go thru orignal owner, which may work.
About the DC offset:
Despite the large series output capacitor, the 8260 has a mute circuit after the cap. Therefore, if something were to go horribly wrong with the mute circuit it may be possible that the Dc signal used to control the BASE of the muting transistor finds its way to the EMITTER, of which is in parallel with the output. THis means that the output after the cap will carry DC; but the HDAM stages before the cap are 'protected' from seeing this DC fault.
It is very unlikely that a transistor fail in this way, and even more unlikely that it failed on both chanels.
If you have a voltmeter, probe the center rca pin out. It should read very low dc-offset. This offset can only come from the muting circuit.
You can also try using the rear L/R as an experiment, and play SACDS in multi mode. If the condtion goes away your on to something.
I hate the reliability of the 1000.00 player. Marantz technical management ought to be ashamed they went to the market with such a dubious design;
But, I can only guess that Marantz's possibly Dilbert style upper management has the final word.
