Danny at GR getting bad Talk Back from many of his viewers

[Randolf]

Initially I didn't planned to take part in this UberBUSS discussion since my scientific background and 45 years of HiFi experience makes me very sceptical on all those type of devices (espcially the expensive onces), but I just found a review of the P.I. audio Group / David Elledge UberBUSS from 2019:

P.I. audio group UberBUSS Power Conditioner Review - HomeTheaterHifi.com

The P.I. audio group UberBUSS can supply up to 40A of purified power to feed your system’s components. It’s easy to install, can be customized to meet...

Guess what according to the reviewer this magic box can even change the picture of your TV :

"I also plugged my 65” Vizio 4K TV into the UberBUSS. The blacks got blacker and the brights got brighter, which improved picture resolution in every way. I had to recalibrate the TV to optimize it for the UberBUSS. A very nice, and unexpected benefit, indeed."

So I probably should not use it for my new expensive calibrated 4K computer monitor since it seems to ruin the excellent factory calibration .

BTW I listened to one of Ron's Sound Clips "When - Patty Larkin" on my Grado GS1000i headphone with Fosi Audio DS2 DAC. I loaded Version A and B together in Audacity and erased 20 sec long blocks alternately of version A and B, so I could listen to it without interruption (to not get fooled by my poor short term audio memory) while Audacity is switching between A and B every 20 sec. Well, I could not hear a difference and will keep my bred an butter multiple socket power strips.

At best, Danny and Ron are liars/scammers/charlatans…
When you see the chicanery unfold between the two of them over too many years, my “benefit of the doubt” well has, in their case, permanently dried up.

Maybe he could power his brain from it, see if it enhances performance there too?

Worth trying. Could not possibly do any harm.

Years ago when I worked in audio sales, we all knew which items paid the huge commissions.

I could make more selling a set of cables or some fancy "accessory", than the actual electronics, or speakers.
The more silly or useless an item, the higher the percentages we got on them.

So there has to be an incentive to push stuff like this, just as there was years ago. I tended to not lie to people, but if they truly wanted that stuff, I would not talk them out of it either.

So I feel like guys like Danny and Ron, see potential sales and customers and dollar signs before anything else. Greed, and lack of being honest.

Yup, it’s really gross. Just another symptom of our hyper-consumerism culture, and guys like that are examples of the para$ite$ that exist because of it.

I watched the YouTube Video contained below.

Then I posted the following comment.

"@SteveMowry-g2u 2 days ago: Correcting (Equalizing) the magnitude of the frequency response could be conveniently implemented with a virtual equalizer rather than with cumbersome multiple passive elements (RLC). There are good freeware equalizer applications available. Passive elements are expensive. Resistors create losses and inductors and capacitors store energy. While the equalizer can also perform room correction!"

Subsequently, the following reply was posted by General Richie*.

"@dannyrichie9743 19 hours ago: Just turning down an area where there is ringing or break up doesn't solve the problem. Also, room correction doesn't really work for the same reason."

Then I thought what would be the response if someone was to post such a controversial reply on the the ASR Forum due to the typical high standards. So having said that, I am posting my comment and the reply in hopes of facilitating a discussion of the controversial topics. Note that General Richie is quite critical of Amir and the ASR Forum.

My hope is that folks from this forum could help me to understand what are the justifications for General Richie's assumptions. Is there any technical merit to his claims?


* Unlike in the military, within the Loudspeaker Industry, a "General" is one that generalizes.

Nope

This is a bad faith distraction attempt on Mr. Richie's part, because your comment was about about the advantages of an active crossover approach over even the best passive counterpart when it comes precise control of frequency response -- and not about "ringing or break up", let alone "room correction."

His reply seems to imply that one must equalize the room effect using passive elements, RLC. He also seems to claim that active EQ does not work! However, EQ in general is not a cure for ringing or diaphragm bending modes. Whereas, ringing and breakup are mechanical phenomenon typically related to the transducer(s).

Exactly -- and audible resonances are as often as not related to enclosure design/construction flaws and/or skimping on materials.
