Buckeye Amps: 2nd Generation Purifi EIGENTAKT 1ET9040BA Amplifier

[Buckeye Amps]

To simplify things as it pertains to this thread/amplifier:

The Purifi (and Hypex, as well) amps, including the 1ET9040BA, will not add to, subtract from, or in any other audible way alter the source sound.

Presumably other than voltage gain!

Dylan, if neither alters the sound, what would be the main reason for me to choose Purifi over Hypex....if any?

Mainly things like power (do you need or want more power that the 9040 offers in monoblock form), timeline (sometimes one vs. the other is on back order or limited stock), state of the art...some people just want THE BEST there is even if it isn't an appreciable audible upgrade.

This is again why I have yet to offer more than 3ch for either the Purifi or Hypex NCx500....because when pricing amplification for surround speakers, the original NCORE MP series is still the best price vs. performance range.

If I may interject but don't take what I think as written in stone etc. I've been wrong before. The reason I would go for a more linear power output from a high power amp is for improved imaging due to much better flatter frequency response.

Yes, there is science in understanding how the mind perceives the measured sound. That doesn't mean the perception itself is science.

Pithy and accurate.

This thread is about a single product:

Buckeye Amps: 2nd Generation Purifi EIGENTAKT 1ET9040BA Amplifier​

and needs some cleanup from unrelated stuff that fit better into some of the several other threads about such things here on ASR.

Please.

Done and a thread ban tossed it to keep the aisle neat and tidy. Please report any further off topic comments.

Forgot to post:
The Micro Audio SMPS upgrade option is live on the website (selected during checkout).

Actually, I have also done a simple test on 1ET9040BA, using the instruments DCA+E1DA APU+E1DA ADC. The THD+N is 0.000066% at 1K, but when the load is connected, the THD+N rises to 0.00030%. Of course, it has something to do with the ground of my power supply. Maybe my power supply is not well installed and not fully installed in the chassis, but later I accidentally touched the output line to the outer casing, and as a result, the power amplifier burned out, and there was no subsequent testing.

Sorry to ask but any reason to buy this over the NCX500 (3 channels)? These are $55 cheaper for the 3 channel version

I believe you mean the Purifi 1ET6525SA (which is not the same as the 1ET9040BA)?

o yes sorry i jus realised this thread is about 1ET9040BA and not 1ET6525SA . Yes i am asking abt the 1ET6525SA

With both the 3ch Purifi and 3ch Hypex NCx500, you would unlikely hear any audible difference. The choice mainly comes down to cost, availability, the better SMPS in the Hypex (for power/wattage), or just brand name preference.

Did you say "Microsoft"?

YES，and intel

Oh that's sad. Bridged amplifiers don't take kindly to chassis grounding.

What the f... their short circuit protection, overload protection did not protect this condition?
That's surprising...
