| Using battery power to go off the City's power grid And @ricevs , trying to bring some engineering knowledge, and expertise to a topic, as opposed to just guessing and often being wrong is not stirring the pot, unless some people do have an agenda or need for attention and that interferes with it. | |
| Using battery power to go off the City's power grid @sbayne, THD is not very revealing of what, if any impact an inverter will have on audio equipment. I am not enamored with pure sine waves because I know what a meaningless goal it is when one considers the equipment connected. I am more inter... | |
| Peachtree GaN 1 Beta I think most people know, but so it is clear, this is not a Class-D amplifier. To be a Class-D amplifier it must have an analog signal and then the power stage. This does not. It is essentially a high powered DAC. | |
| Using battery power to go off the City's power grid @ricevs I do not answer to you. I will never answer to you. Please attempt to show some maturity. | |
| Using battery power to go off the City's power grid unless you have poor equipment Your point of view does not help anyone get better sound, it just gets them to spend money, needlessly based on limited data points, limited knowledge of how audio equipment works, and beliefs about what impact... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? @filipm , The dominant signal in the recordings you posted is 50Hz. It is much larger than any other frequency component. I don't know if that is due to noise in your system, the recording, or it is a demodulated frequency from the noise you a... | |
| Using battery power to go off the City's power grid I didn't state that all inverters sound the same. I said that the Powerwall with my system has no sound. If you read what I wrote, I have pointed out that inverters are effectively large switch mode power supplies and people are just blindly promo... | |
| Using battery power to go off the City's power grid @ricevs you seem to be attacking people, but from a position of weakness. Your contribution has been to report what other people hear. I reported what a Tesla Powerwall sounded like, it my house, with my system (seeing as I have one for backup and... | |
| Using battery power to go off the City's power grid @ricevs , while I agree with you about Viber, are you not doing exactly the same ? You have not done this testing on your own but are just repeating what your friend has told you. I think you have tested Goal Zero but not evident you have tested ... | |
| Just curious if any of you are using a device like this? More voodoo science, like the CD demagnitizer! That is my personal favorite. Proof that some audiophiles will believe anything. | |
| Does a DAC need a large/strong power supply? "but people say they're not that good because of a weak power supply" When people say this, how many of them do you think have professionally designed electronics for audio or other similar low noise electronics? When people say this, ca... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? It absolutely is an inherent fault of the 834P @lewm . No quality piece of equipment should be that susceptible to RFI. It is broken or poorly designed. If other phono-pre don't do it and this one does, that is all the clue you need for that. Tha... | |
| Using battery power to go off the City's power grid @carlsbad, no need to spend money on a PS unit to measure THD. There is lot of test equipment that can do this, probably with more accuracy. You need to test it with real load as well, such as an amp with a linear supply. Most other equipment bare... | |
| Using battery power to go off the City's power grid 120V is the standard voltage. 125 is not even really high. That would be pretty common if you are the near end of a line run. Transformer hum is not from high voltage, it is from DC offset and sometimes from wickedly bad THD on the line. Likely th... | |
| Using battery power to go off the City's power grid NO ONE KNOWS ANYTHING. How many brands of power amp are there? They all sound different.....How many brands of inverters are there? They all sound different. If "only" there was some way to "test" inverters in a consistent, repeatable manner... |
