Could this be one reason tubes (and perhaps records) sound better?
@millercarbon  I believe that we got used to particular system sound, different from reality.  We know that in concert the sound is different but at home we like what we hear.  When I replaced CDP with Benchmark DAC I had impression that sound is ... 
Could this be one reason tubes (and perhaps records) sound better?
I'm not sure tubes sound better - it is just a preference.  Noise is often used in imaging to improve resolution, but in sound it is likely to improve dynamics.  Distorted guitar sounds more dynamic than clean Jazz guitar at the same level.  Added... 
Does Anyone Know Much About Chord Electronics Amplifiers?
@evolvist   My Benchmark AHB2 amp measures better than most of amps available, but it doesn't mean you will like the sound, not to mention cheap amps with fantastic specs achieved by deep negative feedback (bandwidth is one of them).   Bandwidth s... 
Can GAN transistors be used for class A or AB or just call D
Mosfets used in class D amps are non-linear, and almost always N- channel configuration, either half-bridge (Hypex) or full bridge (Icepower).   I'm not sure why there is no complementary pair designs.  All N-channel require charge-pump to provide... 
Do expensive cables/wires REALLY make a difference
@rpnz  Let sleeping dogs lie.

Try different power cord per turnbowm suggestion.   At this point anything is possible.  As for "unplug and reset" you should leave it unplugged for 15min or so.

@s7horton   Is it possible that it is in standby mode, but the bulb is burned-out?  Did you try to play something?

I agree with millercarbon that it might be bad electrical connection.  I have Benchmark DAC3 that suddenly stopped receiving signal from remote.  I opened it and found that infrared diode was poorly soldered on one side.  It was side of ground pla...

If you don't have anything connected to trigger then it has to be something else.  I agree that standby light should be on, even if something in software or lack od signal prevents M100 to turn fully on.  Could it be something trivial, like bad po...

Perhaps "trigger circuit" doesn't work.  Either something is connected but not driving, or something is connected by mistake, like 3.5mm headphone jack. 
Class A 30 Watt Amps: Are they enough to drive my book shelfs?
@almarg Yes, loss will be 6.54dB, but from rated sensitivity of one speaker it will be only 3.54dB.  For 2m listening distance, that they likely assumed as an average, there will be no error.  Sound level at listening position will be the same as ... 
Class A 30 Watt Amps: Are they enough to drive my book shelfs?
@almarg Al, I agree, but shouldn't second speaker make a difference (both at 10' distance)?  Two speakers vs. one should add +3dB making overall error 3.54dB (no error at 2m listening distance) 
Class A 30 Watt Amps: Are they enough to drive my book shelfs?
@almarg Al, remember that there are two speakers, not one (+3dB).    Room gain adds +3dB (or more)  and I'm sitting at about 3m from the speakers equal to loss of a little more than 6dB (9.5dB?).   Rule of thumb has -3.5dB error here, but works pe... 
Stability analysis
@rathi I used many versions of SPICE simulation, including PSPICE. ALTIUM SPICE and LTSPICE. All of them are built on the same Berkley SPICE and only user interface is different. PSPICE was the best of them, when it was still available. I used (Wi... 
Class A 30 Watt Amps: Are they enough to drive my book shelfs?
@almarg For a non-planar non-line source speaker, especially a relatively small bookshelf speaker, putting aside the effects of room reflections SPL will fall off at 6 db per doubling of distance. Al, yes but doesn't it apply to open space or anec...
