| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure I think you can switch between battery power and grid with the app on your phone. You can also have it on a schedule to automatically switch back and forth at set times. I will follow up once I hook mine up in a few weeks. Great discussion thank ... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure Couldn't the underlying problem eventually cause the solution to fail? @jji666 not sure how. Per the OP this is causing the hum on the tube half of a hybrid MC451 - nothing on any other components. Furthermore, per the OP and to dispel a numb... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure Anyone who understands and respects what research is should generally not request a thread be eliminated for sake of regretting his/her own comments within it, once other posters have made significant contributions of their time and knowledge. Th... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure 4) The cause of my hum was eventually traced to a bad amplifier output transformer. Once the transformer and two capacitors were replaced in this amplifier (and in the matching mono block), the hum disappeared completely. Despite my comprehensive... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure @uberk what is your dayjob? You sound like you are in the battery backup business trying to sell everyone on it. Or are you overly enamoured with the green movement? HA. No. Software, cloud, etc. I live in an area with unreliable power. Outage... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure "The hum came from a pair of brand-new MC451s" - My question would be why? @dill my question was and has always been - how do I fix it? I just want to listen to my system with no hum. I found the solution (99.95%). On "why"? Read Steve Huf... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure @carlsbad2 as you have a PS Audio regenerator. In the Steve Huff journey above - he had a P20 then went to Puritan. I am curious what you think of that thread? BTW. I am a technologist. Therefore having the sine wave graph alone is intri... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure @carlsbad2 Thanks for the follow up. Agreed that the Sunday night thing could all be in our heads, but it is such a universal phenomena it is worth looking for both physical and mental causes. To your point @zlone there is so much written abou... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure I bought the Costco Ecoflow Ultra Package with Electrical Panel. Will put my audio on it as a priority circuit. We get hurricanes here so it will be able to serve more than 1 purpose. It's a backup UPS too. I remember Ricevs singing the praises ... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure I just reject replacing all the wiring as the ground is good, and it is on a dedicated line, and in the end, I found a solution. I never said you had a wiring issue. You have an unresolved power problem, which could be benign or not. @eri... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure Just because these products weren’t effective for you does not mean that they are "snake oil." In particular, Audioquest 5000 has multiple features and produces demonstrable, repeatable results. It’s not a fraudulent product, which is what "snake... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure +1 erik and leads to the band aid that the OP used, satisfied that the hum gone, using the "that’s good enough, why do you care solution". @dill I disagree. The above proves it is not DC, not grounding, not grounding loop. Among other things... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure So let me see if I can boil this down. While I’m glad you found a solution, and I believe you when you say you found a solution, your own description of the problem seems to fail to recognize the original issue that led you to a very expensive ... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure I’d love to get one of the consumer battery/inverters and put it upstream of my P10 an see what the incoming looks like. I’m just not going to buy one and return it to Costco. that drives up prices for everyone. @carlsbad2 I would encourage you... | |
| Resolving Hum with Battery Back-up (EcoFlow) vs Power Conditioners: success vs failure Whew! What an ordeal. Good to hear…know that you solved the hum problem. Maybe some components more sensitive than others to poor grid power quality. In the end, that is my conclusion @kennyc If you read the article from Steve Huff on his 2 ... |
