Hi all and thanks for being here,
As a first time noob, firstly WOW!! This place rocks. To Nelson P. You are the reason that I'm even thinking about following this path, the inspiration you provide deserves recognition and note!!
Having read much here and at NP's site, And watching the aforementioned on the tube, I have managed to learn enough to be a danger and not enough to truly understand the subtleties inherent in the designs presented. Further delving is hoped to rectify the situation.
So to the question at hand,
I'm thinking of purchasing two (M.Block) ACA (latest iteration) with a mind to running a pair of Tannoy Cheviot speakers. Am I able to cascode such a project? Is such an idea of merit? Can this be done within the chassis supplied? Can balanced and rca be accommodated? Is it worthwhile constructing power supplies to drive the ACA? Can a soft start speaker protection circuit/PCB be accommodated, again within the supplied chassis? Is the ACA the right way to go, or is there a better way? Am I mad?
Whilst thanks is a little previous, Thanks for reading and for any input you might provide!!

Neat!
...yes? Specifically what are you intending? A little expansion of your intent would be helpful.
All ideas have merit. Wether it's of enough merit to do something about only you can decide.
Maybe? It's not very big, but there is some excess room.
Most likely.
I'm constantly impressed with the PSUs supplied. Switchers are getting better and better every product cycle.
Soft Start and speaker protection are not the same thing, and in this example (ACA) not necessary.
See below
Not at all.
(Or probably better said, "not any more than the rest of us.")
Assuming you want to cascode to get more power, and power being heat (since we're talking about class-A), and this chassis being pretty small, and also the expense of making a bigger PSU, my suggestions are to either 1) build and enjoy the ACA's as designed or 1) skip trying to make the ACA into something different for little advantage and build an Aleph J.
I'm thinking that the Aleph J may be the closest cousin to a pair of bridged ACAs, being singe-ended class A. The ACA will have a different sonic signature due to its negative H2 (neg polarity 2nd harmonic distortion). The M2 or M2x is a slightly different animal, but sounds wonderful in its own way. A pair of bridged (guessing what is meant by cascode) ACAs with the kit power supplies are pretty easy to assemble, and will give an amazing 3-D soundstage. Compared to building a full dual-mono Aleph J with linear power supplies for each channel, the ACAs are a simpler build. Cost-wise, they are pretty close.

Hi Tungsten,
Thanks for your thoughts, will take the time to read and understand the Alpha J build guides, literature, et 'al.
Have to admit, am nervous of taking it on.
But hey, no way of learning without doing.
Am limited by not having access to scopes, veriac, dummy loads, etc.
Want to be able to do an excellent, not ok, job.
Thanks again.

Seems cognac is recommended to complement the F3.
