Sorry to have intruded in your club., gentlemen. I'm out.

6sigma,

Sorry to offend you. Everyone who follows the rules is welcome. Sometimes we poke a bit of fun -- try to have a sense of humour.

Likewise - my poke at the tapatalk signature wasn't directed at you specifically, but at mobile/tablet apps that insist on promoting themselves at every possible occasion.

Thank you Jan

nice try, Devialet.

Any references to support that claim?

I agree that humans can hear signals caused by source signals that go up to 40 kHz if it is played at such extremely high levels that there is distortion and intermodulation products at audible frequencies.

And more importantly, since this is about *music*, do violins produce extremely high levels of >20KHz sound? No. Or any other instrument? No. Or voices? No.

So the debate about whether we could hear such sounds becomes irrelevant - they are not there in the source material in the first place.

Hehe. There are some in the link below as well. Looks like Devialet-D has problems with low impedance speakers.

Well! What I get from that is that either Audio Precision is very imprecise, that journalists from audio magazines haven't got a clue how to run the measuring gear, or Devialet performance is extremely inconsistent. Just looking at THD into 8 ohms, there is more than an order of magnitude difference between the two magazines' measurements, over 20dB in it.

What's a poor consumer to make of it?

Hello, pardon the stupid question that may have already been asked but is it safe to assume that the "Complete Products" offered on the Hypex website such as the MaximonO Amplifierare not using this newer NCore technology?


Thanks

These are still build with the UcDxxxHG + HxR modules.

Hello,

I plan to make 2 mono blocs using nc400 and smps600.
I have a few questions :
Do I need to add a soft start ?
Can I use a wood enclosure ?

Thanks for your advices.

 

[cjf]

Hello, thanks for your response but I don't think I understand what this means. Is "UcDxxxHg + HxR" different or the same technology as what is found in the NC400 everyone is building?

Has anyone attempted to team one of these NC400 amps with a traditional Class A/AB amp in a Bi-Amp configuration? If someone were to do this and taking into consideration the NC400's electrical behavior while attached to a speaker load which half of the speaker would be best suited for this type of Amp (ie..Mid/Tweet or Bass Drivers section)?

For the sake of example, lets say the speaker in question is a B&W 803 Diamond and the Class A/AB amp is a Pass Labs X250.

Thanks

 

[kuribo]

go to Hypex's web site and read their product info.

 

[Julf]

Do I need to add a soft start ?

No, the SMPS600 has a built-in softstart.

Can I use a wood enclosure ?

Sure, as long as you ensure sufficient cooling, and pay attention to ground/earth issues.

The designer Bruno has described that the superiority of the NCore is in the midrange and upwards, especially in the high frequencies. In the bass he recommended the UCDs since he didn't seem to believe there would be any improvement here by using the more expensive NCore as long as it was a proper active setup.

That is not true. If you look at the distortion graphs for both UcD and Ncore, you clearly see that the Ncore is superior in the bass range as well, and those superior specs are indeed audible.

Sure, but the drivers themselves distort much more more in that region. I'm more inclined to believe Bruno

 

[Julf]

those superior specs are indeed audible.

Is that a purely subjective opinion, or have you done some proper double-blind ABX listening?

 

[63781]

They distort a lot more than the Ncore in the midrange the treble as well. In general, no speakers have less than 0,3% harmonic distortion, and usually the IMD figures are very bad.

 

[63781]

Yes and yes.

 

[Julf]

Yes and yes.

Good answer!
