"with informed people" - the guy in the cap is Robert Do (the wooden box "ground" thing is his) is a bit of a snake-oil salesman, IMO. He often says things that are just pulled out of his ass.
i feel so blessed and lucky that i enjoy my aprox 3 grand system with jbl speakers few subs and rather budget amps so i dont have to spend all that crazy 🤑 money to chase pleasure 😛
Interesting that there is mentioned that the system is only 25% of its capability due to the room. Jay Iyagi said the same thing about his room, it being only 20% of its capability.
Install a dedicated 10’ ground rod and connect all equipment in star configuration. Most effective way is run 4awg solid copper from ground rod to a rubber isolated copper ground bus located on bottom shelf of rack. Then run quality 12awg copper stranded wire from bus to each chassis of your equipment. For digital gear, always use glass fiber from router to streamer and only use digital gear than is galvanically isolated, which most better quality dac’s are these days
Here are two points I'd like to make. First of all, when you listen to a vinyl record and compare it to a digital release of what appears to be the same recording, you are listening to two entirely different recordings even though they were mastered ultimately from the same source recording. They are processed entirely differently so a comparison is generally not valid. What's more different phonograph cartridges will sound different and the same phonograph cartridge will sound different depending on how it is loaded. The way in which the art of mastering vinyl phonograph records of decades ago were specifically tailored to sound best on the types of sound system then in use and the concept of two channel stereo remains unchanged today. When I am wrong I'm the fist to admit it. Recent experimentation with bluetooth connected analog and digital recordings of all digital formans and DSD have convinced me that when analog recordings are well made and reproduced they are indistinguishable from digital recordings and DSD. They can all produce excellent sound. I was very surprised. That said, as technology goes there is no doubt that for the purpose of the storage and retrieval of electrical signals that are supposed to be analogs of music (they are very poor analogs) RBCD technology can't be beat and is infinitely superior to all analog technologies in every way that matters. That does not mean you will get better results. You could wind up with worse results from RBCD depending on how it is used such as in the loudness wars. Keep in mind that I am an engineer and a music lover and not an audiophile. If anything I'm an anti-audiophile. EEAS is still down for troubleshooting. The amplifier I thought was the fault still works perfectly. The problem lies elsewhere. It's going to be a job to find it. As for grounding the place to start is with NEC, the National Electrical Code. Grounding is the longest chapter in the code. The code is Chapter 70 of NFC, the National Fire Code. All systems that are not what is defined as power limited below 50 volts must conform to NEC. That provision was doubtless at the insistence of the phone company whose systems operate theoretically at 48 volts but in actuality operate at 52 volts. The code was not designed to improve your audio system's performance in mind, it was designed to save your life and property. The phone company has grounding requirements that are crazy stupid for central offices. The reason is that rather than customize every central office for individual conditions it standardized the design for the worst case in every respect. I was the project engineer for installation of several central office type telephone switches. These are no small items, they resemble large main frame computers with many cabinets and cost millions of dollars. When I was installing an AT&T 5ESS switch the installer showed me a huge copper bar That must have been 3 or 4 feet long, a foot wide, and maybe a little less than half an inch thick. This was his main grounding bar. He pointed to an imaginary line down the center and told me that one side was the clean ground and the other side was the dirty ground. I said you've got to be kidding. To get even one volt difference between one extreme corner and the other you'd have to run so much current though it the bar would melt. Then he wanted a 750 MCM wire to the source building ground with no bends. I told him that was impossible, we were on the third floor, there was an auditorium two stories below. Why no bends? Well because if the building is hit by lightning the electrons could go flying off the wire at the bend. I told him look, this is not a central office, it is a laboratory building. We have lighting arresters on the roof but if the building is hit by lightning this switch will be the least of our problems. BTW the Bell System standards were about as tough as US military standards. An audit of a Northern Telecom DMS 100 switch came up with a finding that a crimp on a lug was on the wrong side of the lug.
@@jaysaudiolab Want more of my war stories? I've got a zillion of them. The third switch I installed was a Siemens EWSD. When the installation was first discussed Siemens sent two people, Northern Telecom sent two people for the first switch, and AT&T sent about 30 people for the second. They were talking about a mile a minute. Each one was an expert on a different thing. When they were done I told them I have one important thing to show you. So we went across the street to the building where it was going to be installed. I told them this building was originally intended as a hotel so there is no freight elevator. This passenger elevator is all you've got so measure the opening carefully to be sure the cabinets would fit inside. And guess what .... when the thing came it wouldn't fit so it had to go back from Red Bank New Jersey to Oklahoma City to be torn down and remanufactured. The guys from siemens wanted me to put a plastic bushing in the conduit between the DC rectifier that powered the EWSD switch and the switch itself. I told him that it would be an NEC code violation. They said they always do it that way. I told him that this was not a central telephone office where NEC doesn't apply. It had to conform. But to make double sure I contacted a department in my company (Bell Communications Research now Telcordia Technologies) called Technology Transfer who set the standards for all of the Bell system. I asked them about it and they sad absolutely not, NEC is OUR standard too. So the switch went in according to the code. Above where the switch was going there was a radio receiving antenna farm on the roof. I installed a special metal ceiling that was grounded completely. On the floor above where the switch went there was the radio receiving room, the only door where my master key would not open the lock. Little then did I know why. As things turned out I wiped out half of the antenna farm anyway. The radio receiving room had been used for the Federal Government to monitor radio signals including from Iraq during the 1991 war. I worked with an RF specialist engineer who was also an employee. He brought a portable all wave radio. We found the source of the noise to be in the EWSD switch in a cabinet called "the super node." It emitted a very strong signal at 7 mhz. I have some knowledge about RF and RF interference. I told him tacking down where the signals was leaking to the roof would be a long difficult job. It never got done. I don't know why because I was more than willing to work with him on finding and fixing it. I love challenges, the harder the better. One more funny story about the EWSD switch. The switch was one that had been installed in the Bell Atlantic (now Verizon) central telephone office in Red Bank. It was only two miles away. I told the Siemens guys that it had to be delivered after 5PM to avoid interfering with employee traffic. So we waited, me and my internal client. I guess I left about 7PM. The next morning I asked my client what time it arrived. He said it didn't. Nobody knew where it was. For about two days it was lost. As it turned out Siemens had to make some modifications to it that they were going to do after it arrived at our site. But unknown to us they decided they would ship it to Kennedy Airport where it was flown to their facility in Florida but they never told anyone. When the Germans sell you something they never really lose control over it. So just be aware of that. 😄
The karma of hearing Jay expound on the love of analog over digital. After only a couple months of actually being able to enjoy pure analog by adding a turntable? Yes analog is that much better!
Dude is just finding out about AC...You gotta be kidding me. How to proclaim to be a Audio reviewer and not know much about this brand. Which blow MSB and all the crap you review off the map.
