Sorry i don't have the schematic, however i'd like some input from anyone about exposure 2010s integrated amp:
today i auditioned this amp, i found out that when u push the power button to turn-on the amp (no problem with turning-off), there would be a "bluupk" sound from the speaker. The sound was not too loud but it was clearly audible from like 1,5 - 2 meter (5 - 6 feet) away. Same thing happen with the second unit, but no such problem occur with 3010s model.
The dealer who's also the importer made phone call in front of me, to exposure office in england and talked with the chief engineer (i forgot the name). This chief eng explained that the 2010s model uses ' high current system.." that caused the "bluupk" sound (i don't realy understand his explanation partly because i know almost nothing about technical issue/engineering side in audio equipment). The 3010s model uses different system. He also said about the 2010s model that such sound shouldn't be a problem, and it should not damage the speaker either.
I read in stereophle mag that 2010s has passive pre-amp in front of a high-voltage-gain power amp., while the 3010s model has an active pre-amp.

I like the 2010s very much (is 3010s better?), with quite neutral tonal balance, good dynamic and transparancy, i would certainly have bought it if not for this problem.
Have any of you known this issue? Any thoughts? Is there any risk of speaker damage ? Thank u in advance.
