Buckeye Amps: 2nd Generation Purifi EIGENTAKT 1ET9040BA Amplifier

[mhardy6647]

I'm confused. He used enough words out of my wheelhouse that I'm dumbfounded. Looking for the dictionary right now. BrB.

Our work is done here.
ahem.
I used to tell people I worked with that someone (to wit, the MD state and US governments -- student aid of many kinds was common when I was in school) paid good money for me to learn all them words -- the least I can do is use 'em when the opportunity arises.

Except the reputation is tainted...

At the moment, only potentially tainted, I'd opine. So far, this little (ahem) imbroglio is being addressed in a responsible and calm manner by all of the relevant parties as best I/we can tell.
Rather a contrast to (another ahem) the Carver "Crimson" amplifier or certain, shall we say, Tektonic shenanigans.

I love a good English exposé for the interest and learning factor but I was erm... lost...LoL. My education did not include those terms... I aced English study but never used those terms in the books that I read. I guess that's the difference between a formal education and a technical education. Keep up the good work and using new terms.

Sigh. It was on face book the day after I made my comments

Double sigh. Didn't change the fact that you were wrong. Face it, you're blaming Buckeye as if he caused the issue. He may have passed out on, but Purifi is the origin of the problem. Your whole schtick has been that Buckeye is being disingenuous.

My point is spend more time checking your facts before you jump on the blame game.

If I didn't know better, I would say you have it in for Buckeye. I don't see you spending any energy going after Purifi. You just keep banging on about him.

You're probably a bot...

It's ok. I enjoy my interactions with James, they give me genuine joy. Like people who used to harp on about our ugly cases.

Buckeye NC252MP Stereo Amplifier Review

Every time I read a comment about its ugliness or that the top of the case bows up, my heart swells with antiaudiophillic pride.

I should add that the measurement anomaly didn’t bother me, because I wasn’t reading it for that purpose. I read all the ensuing commentary after that.

No matter what the issue with 20 KHz, the post that asked what speaker can survive extended 74W of sine wave at 20 KHz sticks in my mind. I think feeding hundreds (or even dozens) of watts RMS of sine-wave signal at 20 KHz into any real loudspeaker will release the magic tweeter smoke in just a few seconds. Thank goodness music doesn’t do that.

And the 19-20 IMD test showed nothing over -100 dB below about 17 KHz. None of us are going to be able to hear that. And that’s even if the tested amp was typical, which apparently it wasn’t.

(And John, you are using a $26,000 Accuphase as the standard for full product testing for a $2200 Buckeye?)

So instead of getting all defensive, hopefully the lessons have been learnt and the quality control practices change.

We are hiring a new QC employee to test 20kHz and above operation

 

[thegeton]

What is you don't understand about the wording? I said unlikely.

No it's isn't. I don't think Buckeye have been disingenuous. They have been IMO nieve and inexperienced in manufacturing and quality control.

They have admitted they don't test amplifiers except for the occasional sample, so escapes are inevitable. Thats policy, not a mistake or human error. The problems with this amp should have been caught by quality control testing. Pretty basic stuff.

Again, how can I check information that is not in the public domain?

From what I have read the modules in question were pre production samples. Again, why didn't Buckeye discover the problem? Lack of testing.

I don't have it in for Buckeye. There is just criticism. Considering he doesn't test amps, how many are out there that don't fulfill spec?

So instead of getting all defensive, hopefully the lessons have been learnt and the quality control practices change.

And you continue to make my case for me. You're definitely a bot.

Purifi is the origin of the problem

I think this statement is premature and whether it covers all observations, who knows. Normally in the industry, the suspect component is returned to the manufacturer for an investigation and an 8D report is requested. Why not here too? This would clean up everything and such a case should not occur again in the future. That would be a win-win for everyone involved.
Btw. from my point of view, the topic of ribbon cable close to loudspeaker cable was also not sufficiently considered/investigated.
This is why a properly conducted RC analysis is all the more important.

Because probably they don't need it if they already knew there's a bad batch out there.
It's tough luck they got caught by Stereophile so they had to expose it.

Because they publicly admitted that they released faulty modules.

However, this is not enough to achieve a good MPL.

 

[pogo]

From my point of view, this is not enough. I would expect at least the 5-Why Method here. The RC could also have affected other deliveries/products.

 

[Sokel]

However, this is not enough to achieve a good MPL.

To achieve such yes,a good report is needed,specially the S/N of the affected modules or else everyone will be in uncertainty.

Ummm.

The difference between real and toy.

Thus, that condemns 99% of us to play with toys in the playground

 

[kma100]

The tone of this thread is getting to be a bit corrosive. I get the need for "perfect", but give people a chance to review/fix before jumping on them. 100% QA is a myth...unless if is handcrafted bespoke product, it is impossible to do this. It's just an amplifier at a relatively low price point and exceeds many expectations...even if it doesn't meet spec (which will be addressed).

Anyway, good cheer and all that!

 

[rdenney]

The difference between real and toy.

I agree. Only the makers of toys can pile on that level of cost to appeal to those few wealthy enough that buying them is like buying the supercar in the driveway—a toy.

Whereas purchasers of real equipment understand and evaluate the relationship between reasonable risk and reasonable cost, and choose accordingly.

But that’s why I bought from a guy I can talk to on the phone if need be, and traded vast cash out of my pocket for the very small risk that I might have to make such a call.

It's kind of Funny that the broken Buckeye Purifi 9040 module will likely sound quite a bit better (more punch, less distortion at high volumes) than my fully working Denon 4700 internal amps. It will be hard to trace these defective 9040 modules without specific serial numbers to match against the defective production batch as they will still sound great even at high volumes.

I was thinking the same thing. This amp pair had an issue, and yet still was so good that Kal couldn’t distinguish it from a bridged pair of Benchmarks and John called the measurements superb and thought the 19-20 IMD issue inaudible.

I didn't say there were. The point was that a product should be as described and perform as claimed. That is law in many countries. Asking customers to pay seperate additional fees for the manufacturer to verify that is pretty dodgy.
Not to mention a customer would be pretty daft IMO to pay additional fees for such a service.
Reality is that proper quality control is simply part of the production cost and normally rolled into the sell price by companies.

Yes, proper quality control should be and is part of the normal process in any serious company. However, what is proper quality control? I would certainly not expect every single unit to be tested - sampling is the norm, and for good reason.
