Not a tech here, but I have had past experience with my techs upgrading power supply's on console center sections, and various console power upgrades and the difference was major. Neve and QuadEights consoles - vast sonic improvements. I am just about to purchase 2 Neve R10's for my new studio build. Do the Neve PS's rate? Or should I go for the Purple Sweet 10's? Or Capi's - but unsure about the never ending shortage of parts Any advice on these? If I knew my way around a soldering iron I’d absolutely build the Capi. And if I lived in Penn (hard pass, no offense), I’d consider the Purple. But I’m in Texas and love RND and HEB (best grocery store on the planet). I have a couple of unbiased (non-Texan) friends who are pretty serious about sound / build quality / power / etc. and they really dig theirs. I’ve been enjoying my Cranborne unit and love all of the extra features, but have been expansion shopping myself and also looking for a straight up ~10 slot.

What ever happened to Brad's (LTL) 500 series power supply testing?
There is a thread on here somewhere.

This may be off-topic, but is it possible to mod the PSU of say a Fredenstein? Was just curious to know. And if so, who'd be the best to ask about it?

I suppose anything is possible. Like a 500 series rack?

Does anyone know about the PSU for this? Is it external?? The image shows a multi-pin plug -- not what I was expecting given the Hyper Matter talk. the differences were not subtle to me. [br Not subtle even against the Purple or API 8 space? This must mean the Chromas are power hungry for 500 modules? If they’re NOT in the higher echelon of power requirement then why would a beefier power supply be of benefit, no?

Power hungry or the others are built to lower tolerances and price point ?

Power hungry or the others are built to lower tolerances and price point ? What I’m getting at is if a 500 series unit is built within spec of a given 500 racks power output then how and where does the sonic benefit come from a beefier PSU? It must mean that either Chromas are pretty power hungry and perhaps use close to the limit of the power that our available 500 series modules offer per slot, right? So the racks are being pushed to their limit and sacrificing sonics to some degree. Otherwise, why would they sound better with a beefier power supply if they were only using let’s say- 75% of the available mAh per slot from the 500 rack? And there’s nothing wrong with the unit being power hungry I’m just trying to better understand this whole PSU and Sonics ordeal as it pertains to my personal 500 series modules and potential purchase of some Chromas

I think you make a good point, but I just remember the psus, often being the Achilles’ tendon in 500 series.
Brad ( LTL), I believe posted a test here some time ago, basically recommending some 500 chassis not really others.
I think of it like power amps: more power is better, even for lower volume passages?

Had a fun discussion with power delivery guru Ralph Skelton (Pacific Innovative) just a few nights ago. Wish I could pass on much of his expertise in these matters but so much of it was WAY over my head. I can sum it up for you though - power matters, and better, more well delivered power makes a difference that you can hear and feel. You can choose to believe it or not. (Most think that if a unit powers up, all is good) But once you have gone down the rabbit hole......it's rough settling for "good enough" ever again. Chroma's just happen to be one piece of gear that I've been intimately involved with developing - so I have a good benchmark for them. The concept flows thru all the gear that we use however. If you have never experienced what modding a power supply to be way overbuilt sounds/feels like, you just don't know - and that's OK. LFAC's were where I originally encountered this phenomenon and a great power supply there can be jaw dropping. Transients, punch, clarity, dimension, low freq extension, size, etc. all come into focus. It starts at your electrical box, is dependent on the wiring in your walls, the outlets in your studio, the power distribution boxes in your studio, the power cables on your gear, and ultimately ends up at the "power supply". All of these matter to some greater or lesser degree. They all contribute to an overall difference. All are small components to the larger picture that ultimately hits your ears. Once upon a time, many larger studio's had tech guys who attended to these matters. Those day are far past us now....

A beefy PSU that you could plug all your 500 series racks into and supercharge them to sonic heaven. I’d buy it. Hypermatter just makes everything take up quite a bit more space for 2 modules in a 1u and the current upcharge is like 500$ per 2 500 series units. It’s just a big price jump and makes the 500 series format not space friendly which is the entire point.

Generally, I think AS takes power VERY seriously. So does LTL. It costs huge money to make what some would consider minimal gains. But to some, those last percentage points are worth pursuing. If you want a mega powered PS for your 500 racks you should find a beefy console power supply and have someone who knows what they are doing (like Ralph) beef it up and mod it to spec. But beware - it will cost big $$$. The last console PS I had modded over a decade ago cost about $3500 to mod.
