Regards,
Yes we have.

We measured (with AP) -118db THD+N and about 129db DNR in stereo mode.

Cheers!

Cheers Merlin.

I am running one transformer/rail... + little one for +5V VD supply.
At least in my limited understanding of electronics, I am

In the pics seems that you are using toroids with two secondaries, so if you are regulating 7 rails, 6 per IVY III & 1 per BII you need 7 Tx.

Use only one Tx for each rail= 7 Tx, you can use also that's you have on hand simply paralleling to get more power & after only you need to add 4 Tx more same voltages & current like you are now feeding the IVY III & voilla, this setup it's to use the Tx that you have, but best will be only 1 Tx with only one secondary per each rail, do you understand me now?

Yes!
Cheers for the explanation.
I might add another Tx, and run the Ballsie off that, and one channel of the IVY3 from each of the others. Mate said he preferred that setup with his B32S.

For now though, I'm just enjoying
The budget is well and truly spent
