Electrostat - M-L; Quad or Soundlab - reliable


Looking for the best electrostat that is reliable. Seems as Soundlab sounds the best performed, but is the most unreliable; Quad is second best performer - very safe - easiest to resell but also unreliable. M-L third, but maybe the most reliable.

Is the reliability issue due to people playing "Pink Floyd at 100 dB" or is reliability also an issue for us 80 to 85 dB people?

Acoustat. The most reliable E-stat ever. My 2+2's are old enough to vote. Been shipped from Florida to Canada and back by truck freight. With new caps and wire (under $100) they will outperform the Quads (just like they always did, read the reviews) and almost match the expensive and unreliable Soundlabs.
Maggies are totally different animals, though they look like e-stats they are not.
For most users, Quad panels last 15-20 years before requiring refurbishing. I do not consider that to be unreliable.
I am a soundlab m2 owner and have not had any reliability issues at all; my bias adjustment is checked on a regular basis and unplugged when not in use.
