Funny how one can forget things like that just because he no longer has power-quality issues, AKA just lets his PS Audio P20 regenerator do its job.

Since my last post...in 2019?...I have a new Massif-brand frontend-equipment rack, made of solid-walnut legs and shelves.

I still have the same equipment in it but for the top-most whatever-it-is (in above pic).

I've acquired MANY PS Audio Noise Harvesters and use one in every duplex outlet in the room that has any equipment plugged into it.. My goal is to remove (as much as possible) the noise generated by that piece from other equipment in the system.. I may be overdoing it, but the system continues to sound better and better.. Purchased and installed SoundLab Majestic 745 e-stat speakers in 2024, consigned them in 2025 to Denver's The Music Room for sale, they never sold, and last December got them back and reinstalled them.. I could do the latter because I removed some cabinets from the front-corner-angled walls which widened (and made safer) the frontend of my room.. The SLs sound better than I recalled and are driven by another pair of fabulous-sounding Pass XA60.8s...BUT...I've been evaluating cooler-running amps for my too-warm musicroom.. For poweramps I still have the XA60.8s...plus pairs of AGD Duet class-Ds (purchased) and David Berning-ZOTL-technology Linear Tube Audio Centurys (on loan).. The latter pairs may be returned, and I have a pair of Audio by VanAlstine M750s on the way.

I'm 82YO this month, and this system is certainly my last one.

Congratulations for your birthday,
I also would like reach that high mileage.
Very nice rack

TYVM twice.  😀

Happy Birthday !  Here's wishing many more, and that we all are as hardy. You must be doing a fine job as I don't recall seeing any issues.

Happy birthday! FYI - I too have a piece of Massif gear, my amp rack.

That Massif stuff surely is gorgeous, but FWIW, I'm still not convinced I chose the right path for a frontend-equipment stand.. Even with solid-walnut shelves of three inches (top and bottom) or two inches, those shelves still ring when nuckle-thumped, and I guess that's why they are called 'tone woods'.. But my mind tells me that equipment shelves shouldn't 'willingly' vibrate at all and especially shouldn't resonate so much that they have a tonally distinct ring.

I'm again fantasizing about custom designing and building a frontend stand using 80-20's extruded-aluminum stuff.*

I'd also use multilayer shelves made of something like bamboo plywood, birch ply', and white oak, glued together with a viscoelastic layer of energy-absorbing glue.. I think I'd make the top-two layers overhang and rest on the long-dimension support structures and allow the bottom layer to hang 'inside' the support structure**.. The overhanging portion (those top-two layers) would be isolated from the support rails with something like the Soft Fat Dots that Herbies Audio Lab sells...

But maybe this is just another dream; at 82YO, these kinds of things get ever harder to do.

* I did this several (maybe 10?) years ago, lost interest in and abandoned the project, and sold the entire bundle to my goodbuddyfellowaudiofool.. Tried to buy it back this year, but he can't find it.. (He's a real hoarder.)
** except for the shelf holding the PSA P20 regenerator which weighs about one-hundred pounds, which would be supported by all-three layers
