Buckeye Purifi Eigentakt 1ET9040BA monoblock power amplifier Stereophile Measurements

My question would be why we need kW amps where 50 Watt amps did the job so far?
(personally I do love these triple number ratings and do use it, to be honest)

 

[Sokel]

My question would be what would an SMPS race consist of?

What is missing from a high quality offering like Micro Audio that would somehow further advance performance?

A space-spec'd one* to absolutely match their flagship and then some,a module like this cannot be restricted to the bare minimum it must push boundaries as everything else is solved.

But an SMPS already exists that can push their flagship module.

So I ask again, what specifically are we asking for in a supposed improved SMPS?

Just wait for my test results and I will show you the boundaries for the 1ET9040 module.

Because I have on the table the 2400W SMPS I will burn the module in front of your eyes by pushing it to the limits.

The only thing I see from your posts here is repeatedly polluting this thread with the same story.

You're talking about the Micro probably.
@MicroAudio no offense,your PSU maybe the nicest (or not),I just want one matched by the purifi team (with their logo and all the bells and whistles and documentation) and their genius in place to maybe think of something different as they did with their amps.

Why just don't you make it short and tell me who sent you to pollute this thread?

And let us put Purifi away from this because Purifi is a professional company led by masters.

I am more than happy to see Purifi & HYPEX SMPS in the market tomorrow, that will make me work harder and create more competition.

Let me tell you something, I had enough of you.

I am asking you not to talk to me or point to my products in any way.

Is it clear now?

I have never reported a post blaming me for something and I won't start now.
So,take a breath and think calmly about what you're saying.

As I thought, you want a "brand name" that will do the same exact thing that is already available.

Predictable.

You missed the last sentence probably.
"different" is the key word.How different?What different? It's up to innovators like Purifi to do it.

If I interpret the datasheet correctly, 1600W should also be possible with a suitable PSU and good thermal management.

Let's all stop the nonsense from the last page or so . It's adding nothing and thread bans will be issued if it continues.

Hook a 50 watt amp to a DQ-10 & then tell me you heard a normal volume level?
Maybe need more?

Maybe you've never had or heard of Martin Logan Electrostatics that dip down to 0.5 ohms at 20kHz? I'm telling you 50W ain't gonna cut it.

@Lars Risbo , any reason you don't recommend the Microaudio PS as the default power source? We know the Hypex is limited to 1200W and not able to produce the 1400W into 2 ohms as shown in the 9040 datasheet. It seems to fit the bill just right. No need to spend extra design efforts on a new PS.

What power supply did you use to generate the power curves shown in the 9040 datasheet? Not the Hypex for sure, since its limited to 1200W, right?

 

[David_M]

Hi David,

With the SMPS1K-SN I pulled 1200W at 2 Ohms.

The SMPS output voltage in idle was +-47VDC and +-45VDC with the 1ET9040 module loaded 1200W.

Sadly, a screwdriver slipped underneath the 1ET9040 module and destroyed it during my test.

Now I am waiting for a new 1ET9040 module from Purifi to be shipped soon.

The SMPS1K-SN has active power factor corrector and the output voltage will remain the same at any AC input voltage range 120~260VAC

Thanks

At what THD level do you generate the1200W? 0.1% 1%?

Why Paul engages with a stunningly dishonest guy like Frank eludes me. How many forums has Frank been banned from now...?

I found Frank entertaining, and he did help with testing of DeltaWave. I’ve stopped participating at CA/AS after a particularly rabid anti-science attack on their Objectify forum (literally arguing that science can’t be trusted). I still correspond with a few individuals there who are friends and/or curious, but like others, I’ve found the place toxic and not worth the trouble. It just took me a bit longer to reach that point
