How to improve power supply?
YES, Mr P: That silence reveals the truth of the saying, "You don't know what you've got, 'til it's gone!" 
How to improve power supply?
Like many other electronic components; regulators generate noise. A number of ways to address that noise have been discussed and tried, by hobbyists and companies. ie: (http://www.edn.com/electronics-blogs/the-practicing-instrumentation-engineer/4... 
FYI: VPI HW-19 motors
If you don't already use them; the SAMA and SDS also make major contributions to the performance of the HW-19. 
How to improve power supply?
If your power supply does have regulators, replace them with Bellesons, which are much quieter(http://belleson.com/download/Superpower_datasheet.pdf). Replace the rectifiers, or bridge, with with either HEXFREDs or Schottky diodes. Parts Connexion... 
Best products for baffle material s ?
BTW, Ptss: You mentioned doing the cabinets in black. Corian has a color called, "Nocturne" that can be polished to resemble a Piano Black finish. Would look sharp, with no visible seams and a 1/2" radius, on all the corners. Personally; I'd dovet...

Of course, Peter. Somehow- I thought you had already covered that elsewhere and that the OP had replied, in the affirmative.

As long as the internal volume and acoustic centers of the drivers remain consistent with the original design; no negatives should arise. Only reduced diffraction, from the baffle. That's hoping that the system was not voiced to compensate for cab...

@Ptss- Some points about Corian; it can worked exactly as wood(routed/dadoed/sawn/dove-tailed), but should be worked somewhat slowly. Drills and taps nicely, for mounting drivers with machine screws and/or clamps(obviating the need for T-nuts). Du...

Mr C- Thank you. Never heard of that company. I'd be interested in comparing the sounds of the various species of wood they use(same models/internals/drivers, but different woods).

So, Peter- no solid hardwoods? Yes; voidless plywood(ie: Birch) has always been a good(and expensive) option, for speaker cabinetry. Probably the most expensive component of any of Klipsch's early systems. In the 80's; I was using, "47lb Industria...

Hello Peter- Saw a lot of talk about veneers, glues and finishes on that site, but nothing about solid hardwoods, or cabinet construction. I'm guessing those are your speakers(PBN). Are you saying that the front baffles(or entire cabinets) are sol...

Peter- Do you know of a company that is currently using solid hardwoods in their speaker cabinets? The last that I can think of were the Cizeks, made of strips of Koa wood, glued together for stablity. Even they used a plastic baffle board(acuthan...

Second the Corian. It's non-resonant and will not contract and expand, as will any hardwood. Reasons virtually no one uses solid hardwoods as cabinet material. 
Audio Additives vs Acoustic Sounds Digital Scale
I've had the AcousTech digital for some time now, which I've verified to be non-magnetic in a variety of ways. Wish I had known about the Ortofon scale, before that purchase. That's a really nice looking unit, and it appears that the stylus would ... 
Rectifier Tubes 5AR4 : New production vs NOS
The rectifier will have a profound impact on the sound of your amp. Mullard GZ34's, manufactured in the Blackburn plant, have a well earned reputation as the best sounding and longest lasting.
