Took a look on farnell; these linears look interesting. I've not checked them in any detail. And I'm not recommending them. In particular, especially for twin supplies (but not only twins), care might need to be taken in power up sequencing. You'd want low impedance (and bloody thick) connections within the supply to bolt the grounds together too. I'd find out what the +/-12v are actually used for before spending money on a better supply. Personally, I'm not risking my unit at all - I'm sticking with stock. If the supplies come up in the wrong order (or with too much gap between) chips can fry very easily - I've seen it many times.

remote sense lead (so you can compensate for voltage drop across supply wires)

You'd obviously need both. There could well be something better there, but the searching is a pain - I couldn't find any multiple output linears.

Some of the specs weren't there, so I had to do more research. Obviously those bloody incompetent scientists and engineers didn't include the necessary units in SI, so I had to add those as well. Sometimes I wonder how they manage to design anything!

Bass: Tight and clean (3x10^8 Kesslers)
Soundstage: Wide (8.314 Blondlots)
Imaging: Pinpoint (7.297x10^-3 Messengers)
Niceness: Warm and cosy (3.14159 Hiragas)
Subtletly, scale, timing and rhythm were all below measurable limits.

Obviously to measure these with any precision I had to put an intelligent chip on top of my scope (which was also powered through a silver plated bus bar direct to the generator). Probes used were unidirectional cryo treated oxygen free copper. The input stages of the scope were valve based. Test equipment nirvana!

PS: In the present climate I should probably explain that 99.9999% of the above is meant to be taken with a wry smile. Any technical information that leaked in is purely coincidental.
