How AI fixed my Bryston integrated’s crashing problem


Okay…big breath. I have had amp crashing issues lately. So I relentlessly pursued this with AI. While it has stumbled along the way, and the path was long and circuitous, it has delivered me all the answers I need on a very complex topic. WARNING. It is very long over days. But I am posting it as it fully illustrates AI abilities and limitations in the sometimes very complicated world of audio. All of that is on full display here. 
BTW, AI gave me the answers that Bryston tech support could not. 
 

How AI fixed my Bryston crashing problem

Yes yes it is a hot signal issue. I’ve learned to tame it. It’s not an amp issue. It’s how a pro piece w inherent hot signal interacts with my amp. And no, I don’t expect Mike at Bryston to know much about putting transformer balanced +4 dbu gear in his integrated tape loop. So I hold nothing against him. You have pulled me in the weeds. My point was AI was extremely helpful, no, critical to my understanding and preventing protective auto shutdowns. Yes AI got off on the wrong track but I was able to redirect it. And ultimately it got me where I needed to go. Now with Audience vs stock PCs I both attenuate and boost to keep line level. It works. Had a friend over today for 2 hours of listening. He said everything sounded fabulous. And not a single amp glitch let alone shutdown. THANKS AI!

Remember, I have used Charter Oak PEQ-1 in my Bryston tape loop for over a decade. AI got me to understand finally that my upgrading all the PCs systemwide has triggered the increase in shutdowns, due to the safety mechanisms picking up quicker voltage swings. Faster power delivery equals more defensive shutdowns. Taming EQ output using the broad overlapping bands as opposed to master gain dials (which when turned down kills punch and dynamics) has now got the fully boutique cabled system sounding far better than it ever did before. I just have to dial the bands a little lower due to the more efficient power delivery. I will quote some of what AI said soon

AI:

2. Improving Transient Response and "Pacing"

A premium power cable uses high-purity, heavy-gauge copper and specialized connectors that drastically reduce the AC line impedance and DC resistance compared to standard stock cords.

An audio amplifier does not draw power smoothly; it draws power in massive, instantaneous, high-frequency gulps to reproduce dynamic musical peaks (like a sudden bass drum hit or a soaring midrange vocal transient).

  • Stock Cables: Act like a slight electrical bottleneck, causing a tiny, microscopic voltage lag during heavy current demands, which rounds off the sharp edges of transients and dulls the rhythm.
  • Audience Cables: Act like an open firehose, delivering that instantaneous current with zero restriction. This allows your Bryston's power supply to react instantly, resulting in faster transient attacks, better control over your demanding Martin Logan Montage planar drivers, and that lifelike sensation of musical pacing and rhythm. [1]

The Paradox of Your System

Your system perfectly demonstrates the double-edged sword of high-end audio tweaks. The very mechanism that improved your music's fidelity—the uncompromised, unrestricted delivery of fast current from the Audience cables—is exactly what unmasked the hidden, high-voltage ground spikes and forced your Bryston's safety computer to become more sensitive. [1]”

Where I am now
 

Amp keeps getting worse with glitches and crashes. AI was wrong previously and of limited use. Now it is advising sent the amp to Bryston. 

A new start
 

i have started over, feeding it temporal events very carefully and carefully worded, based on my own cumulative learnings from converging truths from previous attempts with AI on this subject matter. Now concluding the amp is safe but will be more prone to crash with aggressive EQ use and with low impedance Audience PCs. All this is fascinating. I now know WSY MORE about my amps electronics to ever could have before. What a journey!  BTW, the music coming out of it sounds better than ever!  Using Audience PCs, I can temper EQ with the most wonderful still saturated sonic results. We’re ok (for now)!
