It is more this reason that nearly all tube amps that have a 16 ohm tap will make more power into a 16 ohm load than they will into 8 or 4 ohms
Perhaps that's great for speakers with broad band high impedance. Mine, however, are not.
They are at or above 16 ohms for the first octave only. From 100 to 10k, they range from 8 ohms down to 3 ohms where it continues to dip above that frequency.

Hence my moniker. :)
Sound Lab U-1PX
We've showed with Sound Lab a bunch over the last 30 years...
That speaker has a peak in the bass of about 30 ohms. Since the VTL runs a bit of feedback (tends to act like a voltage source) I would expect it to run a bit bass shy. How do you have your jumpers set?
I also run Acoustat 1+1s in the home theatre system. Again, pics are available by clicking my moniker and following to the galley. I became an instant full range electrostatic fan when I first heard Dr. Cooledge's (JWC of TAS) Dayton-Wrights when I was a teenager. While not perfect, they sounded so "right" on most content. I purchased my first pair of Acoustats when I was 20 in '77.

I heard Brian Walsh's pair driven by a pair of your MA-2s. Sounded perfectly wonderful, but occasionally clipped them on demanding material.

That may well be the case for a Virgil Fox fan. :)
With my previous front end arrangement of GamuT CD-1 direct to amps via attenuators, I was getting flat to 25 hz in room response. When I switched to using a Touch as the player, I lost a few cycles. With my current Sonore µRendu, I sense the bottom octave has been restored. As for me, I find the results completely satisfactory. I need to perform the test again with the current setup.
Here's the third octave plot with the GamuT player:

Jumpers? If you refer to the three rotary controls on the backplate, they are all set to their nominal flat settings.
