Sensitivity: 102 dB
Rated Power: 400 W
To get sound pressure at peaks of 120dB, only 65W is enough.

Hey Bill,
The studio firm I consult for are ATC and Guzuwski & Swist dealers, I have had the pleasure of hearing those and other ATCs (which I really like!) in a studio setup with ~800 W of three-way line-level crossover driven amp driving them.
I don't think people understand how much distortion and compression they put up with in life-like listening volumes until they hear speakers like these ATCs powered by amps which do not clip within the speaker's capabilities.
Also, I agree with whoever it was who said studio monitoring systems require more peak headroom, the mix has usually not been peak limited to fit in consumer delivery media yet. That is usually done in mastering...
Cheers,
Howie
I recently read that the labeling of tweets with "fact check" warnings is now considered to be a bias against conservative views.
Clout being the sole reason someone should simply "take" what was said at face value. This person is so 'n so - who do you think you are in daring to speak up?
It's happening elsewhere besides DIYA, where the bearer of the information is expected to be far more important then the information itself, regarding deciding the validity of it.
The endless "where's your proof?" and "where's the link?" seems pedantic at times, but you can see why that must be continually asked. One would think the last thing anyone wants to do is believe something just because it was uttered by someone with clearly more foundation in Audio than yourself.
Of course the data sheet specs of all the major DAC's and A/D's are done with stock ordinary Pomona cables pulled off the rack.
Yes you can create an experiment to measure the non-linearity of a dielectric, and no cheap cables do not contribute any distortion to anything but a pathologically designed signal chain.
Firstly, I have information from the authoritative book The Art of Electronics. Secondly, to test this process, I created a computer model. Thirdly, I created different cables and just listened to the difference between them. And what evidence do you have?

Funny thing, I think I got a mention of the telegrapher's equation into an AES digital audio standard's references! It was because an idiot consultant designed a stadium system using "Digital Audio" one pair shielded cable with a polyethylene dielectric for only 13 pF capacitance per foot. Of course with a 150 ohm source into a 10,000 ohm load a typical length run would only be down 6 dB. at 5,000 hertz.
Now as far as I know there is no "Digital Audio" standard that specifies shielded cable of such construction.
Prior to this I had one consultant (educated as a pipe fitter) use a 1,000 foot roll of similar cable to move his microphone around the stadium. He then told the amplifier manufacturer that his electronics were not flat frequency response.

If not directly, maybe by way of what they fail to shield against. Why did PMA recommend to use cables with very low shield impedance? Why didn't you tell him that cable design only matters with a pathologically designed signal chain at that time, why wait to say it now?
I've admired their 3 way actives since I first heard them around 1990. In the setting I heard them there was something amiss with the stereo soundfield, but there was something very special about the performance.
That would have been you who said that 😛
Bait and switch. This was a discussion on cable dilectrics and cable distortion. EMC and ground loops is another discussion.
Why would I need to, I see no mention here of these things that one can "hear" but not measure, but simply R/L/C and things that anyone should know if it's their business to know? BTW I don't read everything here.
I've listened to a dozen or so cables of different construction and never heard any difference, that's about the level of any evidence presented in these threads. As 1 said the SINAD measurements of one of our DAC reference designs using the latest AP is totally agnostic to the interconnect cables, the answer is -130dB (for instance) no matter how cheap the cable is.

If DACs produce -130dB distortion, why do they all sound different? Or do you just again not hear the difference?
And yet again, we find ourselves back to the regularly scheduled nastiness...
Not that anyone will listen to this but: one has to ask themselves, "are you trying to validate your perceptions or are you using your perceptions to create a hypothesis and actually test that?"
Latter feeds progress; former feeds regression and polarization. Unfortunately humans are flawed towards needing validation.

Yes, and authoritative authors of books often do not allow their students to make stupid mistakes. For example, use ceramic capacitors in the sound circuit instead of polystyrene capacitors. Since they give the same level of distortion, and this is generally imperceptible, especially in tube microphones and amplifiers? https://www.hi-fi.ru/audioportal/up...ic_s.gif.8b5db98297ef52f3669a4db074695b69.gif
