Hi Steven.
You do have one of the best bass drivers ever available. The Richard
Allan is outstanding.

You are right in saying that someone having problems with his
electrostatic loudspeakers will possibly have to need to adjust his
overall equipment.
But that is mainly true only for a very small numbers of electrostatic
loudspeakers.
Yours, the Shackman MHT85, have the advantage of a being "sealed" by
a multiple isolation layer solution (a great idea and realization of
Alex Shackman ), shielding the diaphragm from the stators voltages and
from environmental influencies, like dust, smoke and wet air.
The only other speaker achieving this "everlasting" performance are
the Quads, they have a dust cover as well, but that is mechanically
very far from being the ultimate solution.

The Quads have a "glue" problem. Despite being engineered at the very
top level of that time and of even of today. But they begin to loose
its bonding status at about ten years age.

So in a case like this, it is not at all "playing around" with the
ESLs. It is a necessity, which you, as an owner of the Shackman
tweeters do not have. A similar problem exists with with the
Bowers&Wilkins DM70. The diaphragm of the ESL tweeter's diaphragm
looses its conductivity.
Here again the Shackman has a great advantage. The diaphragm does not
have and does not need any kind coating. It has an ideally high
conductivity by itself.

So be glad with your Shackman speakers and have a lot of happy
listening hours.

And keep us on track concerning your tube amplifiers. Where are they
available?

all instruments from the bottom up. I was listening to the Antal
Dorati Mercury Living Presecence CD of the 1812 with the live cannons.
I thought I was in the presence of the real cannons...sounded
stunning. Especially with the 845 amp you could hear the crack of the
gunpowder followed by the noise of the shot leaving the barrel and as
for Wellingtons victory which is on the cd as well using period
weapons yet again, sounded like the real thing to me.

system and there in lies the issue. I would leave well alone and not
fiddle with them at all my only issue might be with the cabinets and
that is the only thing I would change given a choice.
