Good job guys!
I’d like to replace the tabs on my 8 ch 252 build regardless if you can share a source for the better tabs.
While in there I think it may also be better to solder the wire to the tab or better yet I may just replace the post to a solder style.

When I post the replacement options/routes for Purifi customers, I will make a separate post in the original Buckeye Amps Hypex sales thread on how those owners could easily replace their tabs if they'd like.

Just waiting to test a few different tab options we ordered before giving out part #'s, etc.

Thanks for the kind words. Had a few hurdles tossed in but came together in the end.

Not bad for a small startup but will get better. :)

I've heard it said a small amount of distortion can add a nice touch of flavor to the sound. You might want to send yours back in to get the steel connectors. Who knows what you are missing?;)
:) yes some other amp peddlers would sell you that as an high end veil lifting upgrade for several k.

Maybe he can sell the different flavor now? Silver tabs are the brightest, golden tabs warmer, black tabs dark sounding. Don't forget one can mix tabs of different colors on the + and - binding posts for alternative flavors. And don't forget the polishing, done by hand of course, until it becomes mirror for the highest levels of craftsmanship. :)

I do, and it is predominantly odd harmonics (3rd and 5th order). If you want any, they best be even order!:)

Yes, things are never broken or have issues: they are just new features for the users to upgrade to. Electronics marketing 101.

There is a certain pre/pro brand I think of with this comment :facepalm:

I think you've been fantastic for a small setup. I wish the big startups would handle things as well as you guys did for a situation like this
I wish everybody would handle everything in this manner. Evaluate criticism, if it's valid, accept it, admit it, and fix it. You have to be honest even if it hurts. This is a rarity these days. Kudos.

Don’t get me started on the audiophool myth that even-order distortion somehow magically sounds better than odd-order distortion.

The amount of distortion inflicted on the signal by the amplifier circuitry (whether it be a tube amp, Class A amp, or anything else) is almost never high enough in level to be audible, unless you are pushing an amplifier close to clipping. What the audiophile press calls the “warm” tube amp sound is largely a function of frequency roll off at the high and low extremes, which can be audible. But even-order harmonic distortion? Doubtful.

Some tube amps, especially simple low power SE triode amplifiers may add distortion in audible level, however, as stated, only as a part of other effects like FR modulation.

Differences between opamps are measurable, but far below any audibility threshold, not speaking about changes due to expectation effect.

Distortion never sounds pleasing, it is always awfull, if audible. Not only harmonic components are added, but also and inevitably non-harmonic intermodulation tones are added, regardless the fact that the distortion would have even or odd character.
