| SUT - electrical theory and practical experience @rauliruegas I attacked your post and not you. There is a difference. Your post contains false information. For example you claim to have presented ’proof’ on multiple occasions. At best you presented ’evidence’ which can be used to point at a pr... | |
| Do Amps matter.. in an Amp? sure, as you said, it's a weird measurement since it doesn't reflect any real useful scenario of use. @dain Exactly. Class D amps most definitely have power supplies!! It can have an enormous effect on how they perform. I'm not saying this '... | |
| SUT - electrical theory and practical experience It’s not that " do not align with your measurements " because the issue is not about just measurements. All tube phono stages needs/necessary a SUT for LOMC cartridges and the ones active high gain tube ones are around mediocrity even the effort... | |
| Hum on Tube Amp - Can't find source being a guy in the land of 10k lakes, motor boating should be natural. 😎 (but it’s probably ice fishing season now,) @holmz My understanding is the two happiest days in the life of a boat owner is the day he buys it and the day he actually is... | |
| Do Amps matter.. in an Amp? Or to say in another way, this measurement was into a shorted load @dain I think you misunderstand- that current is not when the amp is driving a short, its when a short is placed across the power supply of the amp. The output section of a 1000... | |
| Do Amps matter.. in an Amp? I’m stuck on amperage. Most product tout wattage, which I find misleading since the highest wattage amp I own has the least satisfying sound. My favorite amplifier claims >60 amps of current, and a few manufacturers state this measurement. But... | |
| Hum on Tube Amp - Can't find source With the motorboating clue, it would not be unthinkable that those small tubes are involved. @holmz The 12AX7 has more gain than a 12AT7. This can affect the amount of feedback that exists in the amplifier and can also affect something called '... | |
| Peachtree GaN 1 Beta So Ralph, are you saying that the data output (to be sent the the input of the Gan 1) sampled at 96kHz would not necessarily be a restrictive limiting factor to the ultimate performance of the Gan -1? I am. The limitation is in the word length,... | |
| Ditching Class A Amps due to Heat - Sort of a Poll If they are so worried about climate change why were we forced to use old technology like the combustion engine for over a 100 years. @phd For the answer to that, read Internal Combustion, by Edwin Black. Its fascinating reading! | |
| DC entering my amp? @itball Pay attention to what @gs5556 says- he is giving you really good advice for getting to the bottom of this. I would add that if the preamp isn't connected and the DC Offset at the speaker terminals goes up, then the amp is at fault. | |
| Peachtree GaN 1 Beta Sounds like this would be a limiting factor going into the GAN 1 which can accept up to 192khz rates. Am I missing something? Yes. Digital audio uses digital 'words' whose resolving power is determined by the number of bits in the word. IOW the... | |
| When were the best tube amps made? Would be really interested to hear from an engineer and tube amp builder today who has seen and heard many generations of amps. @earthbound For the record, you did if you read this thread. What kind of power supply capacitors did Western Elec... | |
| DC entering my amp? Once every week or two that function gets tripped, not necessarily while playing music. I use good quality cables and the connections are tight. I have a tube preamp ahead of the SPL so thinking that could be it. @itball The amp could also have... | |
| Atma-Sphere Class D… Amazing Good to know this Ralph. But it is not an option when you have a tube preamp - right? @milpai That probably depends on the tube preamp. I don't leave any of my equipment on all the time, except my DAC. | |
| Atma-Sphere Class D… Amazing We have several reports now that leaving the amps on helps them sound better. |
