No horns here , that was MEP , he got tired of clipping his AR on his NOLA's and switched to , a Quasi horn setup........
anyway, the HYpex current limits heavily into 2 ohms , but has enuff there to make do , problem is heat soaking driving low Z and PSu sagging, big sinks or a fan like crown does on their class D will help here. problem with ASR is no sine waves to clipping pics , would love to see the symmetry and of course they are allergic to square waves. Amir tests are skewed to make class D look superior and in some respects the measurements are excellent , but its not the whole picture ..
tempted to give one a go , low heat , low draw when just doing casual listening would work for me no need to run the behemoth for casual listening time ...

Yeah I guess we'll never know.
Cool, nonsense and sense in one sentence. 500+ into 2 ohms for a 250/500 8/4ohm is plenty and good performance, especially for the ridiculously low price. A great many "audiophile$$" amps can't drive 2 ohms and unless the speaker has idiot "injurneering", that much power>load would be more than suffice. Hopefully I didn't insult your mystery speakers.
Actually it is the whole picture. His and JA etc who do test, show that the Hypex, Purifi et al are superb, transparent amplification, capable of outperforming human hearing, including yours, in the really, real, non-imaginary world. But that doesn't mean the sight and "knowledge" of them can't/won't lead to audiophile melodrama. So YMMV.
Well, unless the secret speakers are low sensitivity and/or audiophile injurneering impedance, they will be every bit as transparent as other well designed SS, at any sane level. As I will continue to demo, In public.
Si yuh soon.
cheers,
AJ

Explain to me at what level is your understanding AJ, apparently i keep speaking over your head :baby:
200 into 8 is 800 into 2 if no current limiting , so 500+ into two is serious currently limiting , this is basic even for a Campion nutter , this level of limiting ( and heat soak) will rear its ugly head , on anything but a 8 ohm speaker well for those who interest is actually accurate timbre, drive and ultimate sound ...
So on a 8 ohm load i can expect decent sound , with the accompanying low Z of 4 ohm, not on a 4 ohm which could see 2 ohm , you should try and learn what phase angles due to amps with falling PSU and current limiting ...
BTW Audiophile injurneering is usually accompanied with digital eq, xovers , blah blah blah , mega compensation , producing poor timbre/timing, splish splashy sound at best , the deaf and blind can partake , something for
everyone ..
To each their own, heavy Class D lifting in public is fully supported , as is Class A, AB, SET, SS or toobs, so carry on ..!
How is that for nonsense and sense .......?

Yes, my formal EE education, microwave/radar/satcom/30+ years of varying engineering work, actual products and public demos, puts me at a serious disadvantage to an audio forum expert like yourself Mr Wayne.
Without serious cherry picking show me the list of real world 200w/8ohm amps putting out 800 into 2 ohms...and I'll show you a list 1000x bigger that can't. If 500+ into 2 can't drive your mystery speakers, that's purely on you. More than plenty current for the 99.99% of non-pathological engineered speakers. Since you're understandably way too embarrassed to reveal anything about your system, you can't even claim "well my amp can" ;-).
Like your system you're projecting. Well. we'll have to take your word since no one else will ever hear itBTW Audiophile injurneering is usually accompanied with digital eq, xovers , blah blah blah , mega compensation , producing poor timbre/timing, splish splashy sound at best , the deaf and blind can partake , something for everyone ..
.Unlike my countless demo's of electro-acoustics and perceptual knowledge. No hiding. See yuh in Room 1215 :hey:

Fail to see where your experience has anything to do with audio , EE’s are dime a dozen even i have one , my Audio experience supersedes yours by decades with actual achievements , sales customers and patents not simple high school designs then walk around like a Big wig doing demo’s ..!
So yes you lack understandings in relations to most things audio , never questioned ur education , microwave knowledge or experience , makes sense now that top end could fry eggs ..!
Small hint learn up and show some respect goes along way in receiving some ..!
Yes we can arm wrestle in your room ..

I'll admit that your white van speaker business has been around a lot longer than I've been a company.
Too bad everything about you is always a secret, but that's understandable when its all purely imaginary+blah

FWIW, the amp is going to behave as a voltage source to within a couple dB of full power. So at normal listening levels the 2 Ohm thing really isn't a concern. Usually when you run into those 2Ohm impedances with weird phase angles its at a certain frequency and not the entire impedance curve so in practice this will be an issue for only a very few.
FWIW, when the amp is asked to drive a harder load its going to make more distortion too. I don't see the point myself- I've always had the impression that high end audio was about getting away from distortion and closer to the music. There are plenty of easier to drive speakers that sound just as good or better than those that are not easy to drive (and some of that comes simply from the amp making less distortion).
IMO/IME if high end audio reproduction is your goal, your amplifier dollar investment will be best served by a speaker of higher impedance and higher efficiency. If sound pressure is your goal, you have a (IMO) weak 3dB argument for lower impedances, along with which speaker cables become far more critical.

With all due respect Ralph, such nonsense , pushing lowest distortion mantra while designing high distortion toob amps, is just more cognitive dissonance than engineering, when does the distortion matter ? I have yet to hear your versions of high Z and efficiency best low Z , low sensitivity setups, (ribbons, ESL's, etc ) most of us are driven by results not meme's and well wishes...
Cmon man at least be genuine with your responses .....

I was being absolutely genuine; remonstrations of your word salad (2nd to last sentence of your post above) notwithstanding.
I was explaining how an amplifier that behaves as a voltage source works, in particular how it works when presented with a load of lower impedance than it can double its power at full output.
I was also explaining the downside of difficult speaker loads. To add to that- let's say you have a speaker that's low impedance; if you could have that speaker be somehow higher impedance it would sound smoother and more detailed on nearly any amplifier on account of less distortion from the amplifier. So it might 'sound good' to you right right now; if higher impedance it would 'sound better'. FWIW the extra distortion generated by most amps when dealing with a lower impedance tends to be higher ordered harmonics, to which the ear is keenly sensitive and also perceives as harshness and brightness.
Regarding when distortion matters: it matters when its audible. FWIW our tube amps tend to be quite innocuous in this regard. Our class D amplifier even more so.

Hi @Alkyogre,
What Bryston Pre-amp an what speakers do you have and have you tried mid Gain setting as well??
