The Black Hole......

Yesterday afternoon had the opportunity to talk to someone who had the opportunity to directly the compare the sound of a Cary CAD0300SEI with a Bryston 3B-ST, the two amplifiers Cheever used as examples. The person emphatically stated, "Nobody who compared the two amplifiers in the same room at the same time would choose the Bryston over the Cary!"

Don't know why that would be myself, guess its something that has to be heard to be understood.
You should've asked the same questions you've asked on this forum before.
"Are you ready to say how you selected your test subjects? Demographics? Randomization?

Did they have a chance to train on the equipment prior to testing?

Any positive controls?



Have you done any college coursework in sensory testing?

Have you studied any of the present-day academic sensory testing literature?

But the reviewer said
The 300SEI was a musical revelation, providing a totally involving and musically euphoric experience night after night. The 300SEI excelled in the most important areas: harmonic rightness, total lack of grain, astonishing transparency, lifelike soundstaging, and a palpability that made the instruments and voices seem to exist in the listening room. Beyond these specific attributes, the 300SEI communicated the musical message in a way that went straight to the heart.


How can you not have spotted that in your listening Howie 😛


P.S. That review was of the time when I read stereophile and I remember being intrigued by the Infinity prelude speakers. They never made it to our shores though.
 
So we have the thing that is expensive, has very low power, high hum and at best can sound similar as normal amplifier only in case that EQ for speaker impedance is used. So what is the point? Why such thing?

Pavel....pretend you are a person who is not an electrical engineer, this will be a tough one for you but try...now: You have a bunch of money to spend, which one would you rather watch while listening:

OK, that may be beside the point. I do think there are people who prefer hearing a sweetened-up 2nd harmonic sound, not the original. To each their own. Some people buy famous paintings and poorly illuminate them but prefer the way that looks.

It occurs to me that we here are constantly confusing the production and reproduction of music. As someone who has spent a bit of time on the production end, I can tell you accuracy in electronics is paramount. Once the product gets to the consumer, they can do whatever they want with it and vendors are lined up to help them do just that. I can't call that wrong, but I have no interest in it from any other than an accuracy POV, but then again, like pretty much the rest of you we are not the usual consuming public.

Would you care to recant the claim (shown below) you've made recently?

Of course, now I trust the Lord of the Blue Screen only.

Only measurements tells the truth, all the rest are speculations and biases.

A 45 or a 300B DHT amplifier with poor measurements surely will sound bad, much worse than a Hypex amp with spectacular measurement graph.

I wonder why people continue buying and building tube amplifiers.
Maybe they have not understood that audio has evolved to Class D, Class A is only for cooking.

Well, I am sure there are more than a few people who read what I just said and conclude I am deaf as a doornail...we all support our belief systems in our own ways. I will say my audio electronics testing methodology has had a hand in the sound and/or production of more audiophile recordings out there than most people...so make your own conclusions...

Not the level matched double blind listening test.

But now you are right back to subjective impression. 🙄

Why not ask them. It would help the marketing section of your audio business.

A stadium empty can have a noise level around 35 dBA. The noise level should be 20 dB below that to not be noticed. (Things like hum being narrow band are not masked by louder wide band noise.)

For some reason it is nice to have the reinforced sound at least 10 dB louder than crowd noise. Then there is another 10 dB minimum above that for enough dynamic range to reduce perceived distortion. A quiet stadium crowd runs 85 dBA. So that requires 15 bits. A bit of a trade secret as to how loud a crowd really can get. I see numbers often given in sports circles that are complete nonsense. But although some folks claim 24 bits of dynamic range, that doesn't really happen and fortunately isn't needed. Of course 16 bits isn't really enough.
It seems like you need a quite stadium sound system and a big crowd sound system.
