what's going on with specs?
Power and distortion specs are just a minor reference point. A 30wpc amp isn't going to have the same power as a 250wpc amp but that is about as much information you can get out of a spec sheet. A watt is a watt but some watts are more equal than ... 
To pre-amp. or not to pre-amp!
A cheap preamp is a wobbler, a good preamp is a no-brainer. Get a good pre, your system will thank you.  
Execution matters
You have described mass market equipment, high end gear doesn't suffer through that process.  
Recommendation for a highly resolving amp
You have a very nice system so it's hard to say where your issue is. However I would try a Sanders Magtech amp if you are looking for a new amp, they are designed for electrostatic loudspeakers and do that job really well. 
Analyzing Balanced versus Unbalanced Amplifiers--Difference in sonic quality?
You got some terminology issues with your post. Not sure what you are trying to say but if I can take a guess, you are talking about signal processing. My experience has shown that signal processing as a general rule doesn't always work on a broad... 
A little tube magic?
"...It seems it could be pretty expensive swapping 6+ tubes on the regular..."A legit concern, you could go broke running 5 channels of tube amps. My opinion might not be popular but you can run a good 2 channel system for music or you can run a m... 
Why do amplifiers sound different?
"...Coming from a electrical engineering background, amplifiers theoretically should all sound alike as when measured into an 8 ohm load, their frequency response is extremely flat..."What ever measurements we make, they really don't tell us how... 
old console stereos with new electronics?
Refinish, repair the built in speaker, maybe fix the old tube amp. They are still useful today if you have the room. 
How much does power amplifier really matter comparing to other hi-fi components?
Depends on the loudspeaker. If you have something really efficient, a nice pair of Quicksilver monos will do the job. But if you have Magnepan 20s, the sky is the limit.  
Collective letter s to Stereophile
I read this kind of stuff all the time, even in Stereophile's letter column. Geese, just don't buy it if you don't like it, for crying out loud.  
Analogue from Digital
Back in the day, I had vinyl and early CDs of the same album from the same recording and time period. I'm guessing these were AAD CDs. Tape hiss was readily apparent on the CDs. Anyway...They both sounded very similar but the CDs lacked the pops a... 
How Do You Learn?
Find a hi-fi shop with the best sound. Learn what you like, then try to duplicate what you heard at the shop and make your home system sound the same. 
Emotiva Basx a-100
If there is no screw on the knob, they just pull off. Some are a bit stubborn. Then blast out with some tuner spray.   
BI-WIRING VS DIRECT (2X2) CABLE for Martin Logan SL3
Buy a good pair of single run cables. I like solid copper for most Martin Logan ESLs.
