Dear a.wayne, I’m sorry, but I do have a question: What’s beta droop?

I really hope this is not a spelling issue again, because that would be really embarrassing. If it is, I’m so sorry.

I was just starting to like your soft side ..!

Access Denied

A Bit windy , short internet lay lay grammar uncorrected version , its when the output stage is under sized for the task so you lose gain drive and output current as load impedance lowers , this is obvious on this amp hence the massive drop off in power below 8 ohms.

PS the link is good ...!

Dear a.wayne, too many errors for me to comment on. I’m terribly sorry.

You may want to consider a tutor.

Back to audio

Does the Humboldt suffer from beta droop?

**Kuoppis** · July 23, 2021, 01:40 AM

That guy is harmless, that’s why I didn’t bother to comment. But basically, the insinuations are complete bollocks.

Back to the facts:
- 400.000 microfarad capacitance
- double mono layout with a total of 1900 VA transformers
- damping factor of 1.800 at 10 kHz and 10.000 at 100 Hz

That’s more power on tap than most hi-end separates.

Ignorantly proud now are we , the biggest difference in audio today vs 4 decades ago , Is how much it has moved from being a fun hobby, to full on cult ...!

The Specs from Audionet clearly implies its an 8 ohm only amp as it heavily current limit into 4ohm and below , of course this is only a problem if your loudspeakers represents a lower Zmin than 8 ohms which most do . Mostly this implies you choose your speakers carefully has nothing to do about who is liking the sound , its technicality vs preference ..

Halcro is another which comes to mind , excellent build but really an 8 ohm load amplifier for best sonics ..

Carry on ...

**Kuoppis** · July 23, 2021, 06:38 AM

Dear a.wayne, have you ever come across the term ultra-high frequency amplifier?

With more careful study of the specs you posted, you might have noticed that the frequency response of 0-700 000 Hz is quite unusual.

Getting the concept might in turn allow development of a basic understanding of a design not focusing on class A and doubling the power from 8 to 4 to 2 ohms impedance, as the benefits those are achieved through other means. Also, have a look at the damping factor again, and you might understand the foolishness of your statements.

yes! i wonder if there will be a scientist stereo amp in the future.

btw miika, how is the impression with the humboldt now after a few weeks. did you notice further benefits from break in?
if i remember right you do have a kharma speaker coming in. any new from that side? i hope they are going to match well.

I noticed an improvement in the soundstage after a couple of months, with the amp kind of opening up.

Regarding the speakers, that will take some time due to custom color.

How about yourself, have you replaced the Tune Tots?

**u-sound** · July 23, 2021, 09:03 PM

no, you cant replace tunetots. best speaker in the world as for desktop application.
mine are setup to perfection by the millimeter over many monthes and will only be replaced when a new version will come out in 2 or 3 years.
the synergy with the humboldt is amazing.

well yes, it will be interesting how well they pair.
i had the humboldt with the sabrinaX and power wasnt enough for high volume.
just as it was described in the review, double bass will fail and things fall apart.
however, this happen with most amps and usually much earlier at lower volume.
when things match each other, humboldt has a worldclass bass. an extraordinary good bass.
the other things he described (enhanced texture, fullsounding), nope, thats a question of cabling and tweaking. at this level you take your time if you want it to your liking

**a.wayne** · July 23, 2021, 09:59 PM

Yes if speaker load (Zmin ) stays above 8 ohm i can believe it will be good , reminds me alot of Halcro , given a bad rap because most tried to drive large lowZ speakers with them , at 8 ohm it was a world class Amp ...!

I’m currently running the Humboldt with Sabrina X’s I have on loan, and can’t really relate to your comment. I’ve tried the Humboldt on probably 50% power at the max to test the volume, but that was too loud for listening.

I would guess you probably have a source volume control somewhere in the system you’re not aware of (PC, DAC etc.) which is limiting the output volume.

hey, everybody loved the humboldt / sabrinaX pairing. it was playing beautiful. nothing to complain.
it has power to pop the drivers, no doubt.

sabrinaX with heisenberg will play completely unstressed even at very high volume in a very big room.

The Sabrina X’s go well with the Humboldt, nice pairing. I was surprised how good the tweeters are.

Would love to hear your Heisenbergs at some point. Maybe a road trip to Switzerland?

Which speakers are you using with the Heisenbergs?

**u-sound** · July 27, 2021, 03:21 PM

welcome flemming!
that will be a long travel...

my system is on the way to become youtube and internet only. basicly i stopped streaming from quboz and tidal and also gave the cd collection away.

**a.wayne** · July 27, 2021, 03:42 PM

Gave away the CD collection , regrets in 3,2,

Regards

**u-sound** · July 27, 2021, 04:28 PM

lol, no, not a second so far.
cd is pain in the ass and has no picture vs youtube. sad old world.
internet: live events, netflix, tv....

all you got to do is networking. then you get all the above in cd quality and beyond.
marketprice does reflect this. when i wanted to sell the collection i ask a guy who owns a shop and he told me i can bring him them thousends of discs but he will give me NOTHING for them.

**a.wayne** · July 27, 2021, 05:47 PM

Thats the usual talk to acquire free CD’s or LP’s ..

CD’s regularly sell for 3-25 bucks all day everyday , for those willing to deal with them. there’s no CD quality from streaming or server IMO, well thats been my experience from multiple compares ,in many settings. Music originally done on CD format will sound best with CDP’s , streaming is best for highdef recordings originally done for streaming /downloads , its the same of analog LP those recordings sound best on a TT..

Regards

**u-sound** · July 27, 2021, 06:12 PM

you are right, thouse damn cd s sounded great and i am lying a little bit to myself.
on the side the differences are no more a dealbreaker and you will find lovers in each camp.

from another view, all this doesnt matter no more for me as my application is internet and i try to get it as good as possible. at the moment quboz sounds better than youtube but i think i get it very close as it is the very same thing.

btw the shop i was asking is selling NEW cd for 3-5 dollars. mine were 10 to 40 years old, bad condition, no casing.

Hi guys, i'm going to try to organise a shootout between my Gryphon Diablo 300 and the Audionet Humboldt in my system.
The Audionet dealer would be ready to bring me his Humboldt to make this shootout.
I think this has never been done and should be fun.
I'm curious to hear if the Humboldt can handle the load of my Thiel CS 3.7s as well as the Diablo 300.
I'm not planning to purchase the Humboldt for my present speakers but most likely for my next rig with this time around Borresen 03s.
Will keep you guys posted.

Am a previous Diabolo owner and now have the Antileon Evo.

Looking forward to your thoughts, but surely the Humboldt will win this show down?

**ICUToo** · October 24, 2021, 11:37 PM

Gryphon vs Humboldt will depend on the speakers, I suspect.
Gryphon has greater ability to drive speakers, in my experience of the Antileon (not evo), whereas the Humboldt sounds very real- faster transients, clearer, more natural treble, relaxed presentation with unforced detail, a midrange that genuinely surprises you sometimes when you open your eyes and Norah ISN'T standing on your carpet!
This was all based on audio memory, so the results of a "live" shootout will be interesting!
Have you another pair of speakers available, to try them both on different speakers as well?

I don't have other speakers at the moment but like you stated the Diablo 300 will have the advantage of drive ability in this specific case.
On all other aspects the Humboldt should be much better and it better be considering the price difference between the 2 units.

**u-sound** · October 26, 2021, 05:29 PM

thieliste...wow, if the dealer is doing such work, take it!

looking forward to your findings.
btw congrats on your new system! very well selected imho.

**u-sound** · October 26, 2021, 05:46 PM

hey kuoppis, long time no see, how s life? very busy?
i see you implemented the sabinasX in your signature. settled with them and cancelled the kharmas?
how do you like them compared to your ex-lansches? what color are they? wife likes them?
in case you get the kharmas later on it is also very interesting as the size of all those 3 speakers is very similar yet another concept.

Yes, keeping very busy

But I’ve also lost interest in this forum, and therefore disengaged, as meaningful discussions are hardly possible anymore.

Every thread is railroaded into nonsense by some wannabe (often from Mike’s local Florida audio club), if you escalate it you are insulted by some lowlife supposedly administrating the forum. And Mike appears to have lost his touch to commerce a bit. And then everyone seems to think this Jay guy is some kind of semi-god, while he’s just a rather average self-aggrandizing show-off (his ramble on top/ mid/ bottom amplifiers just caused some vicarious embarrassment).

In a summary, not worth my time.

You're absolutely right (RE:" ...CD’s regularly sell for 3-25 bucks all day everyday")

Whoever tells anyone CD's are worth/valued at 'zero' is naive -and disengenous.

I remember a similar erroneous prediction from a co-worker regarding LP's/vinyl future
value (cirda 1989/90): "You won't be able to give em' away next year (LP's)".
I replied: " ..Ahh, I bet CD's will come down in price and vinyl always sought after while
the mint-condition/premium examples will command top dollar"

In all fairness (honesty) I never foresaw the vinyl resurgence boom in the 2010's-to-current.
But then again, I believed CD/digital would eevntually reach/surpass vinyl records inimitable
music making capability. Not so. At any reasonable price point anyway (under $10K?).

But more than dolar value, I find it difficult to understand why music lover's would dispense/sell
off their treasure music colletion; so much history/memory -meaning behind it all.

Can't wait to hear your impressions. The Diablo 300 is very high on my RADAR screen, as are the Pass INT-250 and Boulder 855. Don't think I can afford a Humboldt, but will be very interested to hear how the two compare.

In short this Integrated is in a league of it's own, nothing comes close in the world of integrated!
....
I was not expecting the Humboldt to handle my Thiels so well, actually much better than my Diablo 300.
It is also much more musical and smooth than the Diablo 300.
The synergy with my Thiel speakers is shockingly good.
We used Tellurium Q Statement SC and IC for this demo.
I'm not able to keep this unit because the distributor needs it for his demos, it already left.
Anyway i'm not in a hurry, i really need to think about this and perhaps wait to be able to afford a Heisenberg/AC Impera ll Ref combo.
This would be end game for me."
