| What are the best GaN Amplifiers available today? Generalized statements are painful. While Ralph may prioritize noise elimination, is it true that he believes it is the only thing that matters? @blisshifi Of course not! @ricevs apparently has a lot of misconceptions and is putting words in my... | |
| Matching the cartridge to the phono stage The Hana SL has been on my table for the past two years, running into a Parasound JC3 Jr. (which allows me to adjust MC load using a variable pot that runs from 50-550 ohms). I can say that the differences in load between 100-400 are subtle, but ... | |
| Do Your Speakers have LEVEL CONTROLS or EQUALIZERS? (Vintage or Modern) ??? Their literature is clear: to adjust for 'live/hard' rooms, or 'soft/dead' rooms (of various degrees of soft or hard of course); for various locations in a space; for an individual's preference. @elliottbnewcombjr Yes, I'm sure the document sai... | |
| Is My Tube Amp Unfixable? Help Needed Btw, the amp is noisy no matter where it's operated, so not an RFI issue from what I can tell. @bojack The RFI could be generated by the amp itself due to oscillation. | |
| What are the best GaN Amplifiers available today? Folks, just so you know, if you are going to be successful with a class D product, one thing it has to do is meet EU Directives for radiation, so it can obtain the CE mark for use in Europe. In the US, you have to meet FCC part 15. But its more t... | |
| Is My Tube Amp Unfixable? Help Needed @bojack Don't panic! This is solvable. The first thing to do in a situation like this is move the monoblock to the other channel and see if it does it there. Apparently the other monoblock is fine, right? If its quiet in the other location, th... | |
| Atma-Sphere Class D… Amazing Is there an official answer whether or not it’s ok to leave the atma-sphere class d amps on 24/7? Its fine. The only concern is when turning a preamp on or off you might get a substantial thump so I would shut the amps off during those times. | |
| 300b lovers What is the minimal inductance is acceptable for 6sn7 interstage transformer ? 80H, 70H, 60H? The problem is transformers with high inductance have narrow high frequency bandwidth. But if interstage transformer doesn’t have high enough inductan... | |
| What are the best GaN Amplifiers available today? Maybe since you’re now on this thread, could I ask you to share how you voiced your GaN monos, especially in comparison to your OTLs? Did you attempt to preserve the same level of openness and bandwidth to your other amps (albeit making it easier... | |
| What are the best GaN Amplifiers available today? Which AGD amps did you compare to the Atma - were they the Audion? Would you characterize them as rolled off on top, or just sweet? @blisshifi If you look at the comments comparing the Atma-Sphere amps to the AGD, you'll see that they contradic... | |
| Do Your Speakers have LEVEL CONTROLS or EQUALIZERS? (Vintage or Modern) ??? @elliottbnewcombjr The reason vintage loudspeakers have level controls is because the output impedance of the amplifier was an unknown. So the controls allowed the end user to adjust the speaker to get flat frequency response. They were not there... | |
| Why is solid state more popular when tubes are better? My speakers require a lot of power, so a set tube amp may not be the best choice. @emergingsoul Speakers that need a lot of power have a lot stacked against them! There's something called 'thermal compression' which is a reduction of dynamic co... | |
| Atma-Sphere Class D… Amazing @audioquest4life Into 16 Ohms they will make half of their 8 Ohm rated power. As you already know though, that's plenty for the T1s. You might have to adjust the rear panel controls slightly since the class D has a lower output impedance compared ... | |
| Competitive class D amp suggestions For the Atma-sphere class D amp: Is a preamplifier necessary if only connecting a streamer/DAC to it? The streamer/DAC has it’s own volume control (if I want to enable it). Lumin S1. @veerossi Most digital products can drive it directly with ... | |
| Woofers pumping @tomcarr Swap the channels left for right between the amp and preamp. If the problem moves then the amps are off the hook. Since you tried 2 amps you probably don't have to do this test, but you do have a source which could be the problem. Swap t... |
