An audio pre-amplifier, really bad
joeqsmith:
This has to be some of the worse design/workmanship I have seen for a an actual product.

Some old '70s audio equipment (SAE and maybe Soundcraftsman IIRC) were notorious for their "hand made" internal appearance. That's right up there with the worst, but they had some peers. But what do you want for only $4-5k? If you want a tube preamp that isn't a mangled mess, you'll either need to settle for a Chinese-made one at that price (Prima Luna, which is a bit neater, go for $5k or so) or step up and pay some real money.

It's $137k but at least the wiring standards are up there with the average Heathkit power supply.

looks like tom evans has some competition

From the review:
--- Quote ---At some point, we inserted Finite Elemente Cerabases under the preamp and its two power supply boxes, which rather significantly improved the sound in all the ways that one might expect.

Didn't know what is a "Finite Elemente Cerabase" so I looked it up (https://www.finite-elemente.eu/en/cera-interfaces/cerabase-classic/):
--- Quote ---The top-of-the-line model of the Cerafamily harmonizes transparency and three-dimensionality with precise definition, rich tonality and vibrant dynamics. The newly gained integrity and emotionality of the music enrich the listening experience beyond comparison.

So what are they?
They're goddamn metal feet that you stick under audio components. Only 880 €
Fuck these people. They believe in pure voodoo.
(WTF??? Two massive separate power supplies (60 lb. ea.) for a fucking preamp??)

In Supratek''s defence, they state its a prototype so workmanship & use of glue, no labels ... makes sense. On the other hand a serial 103 speaks against being a prototype, unless they started at 100 to make it look as if the amps are more commercially successful ;) . Also it has been savagely butchered by someone. I could understand if components were removed as parts-donation to other amps but why snip-off the leads of the output transformers? Possibly they sold this for parts and wanted to make sure that it can't be revived.
It would be nice to see the inside of a production unit for comparison. On the whole, I am not into audiophoolery but appreciate insights into the design and build of any piece of electronics as an opportunity to learn of good & bad choices.
