| 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. | |
| When were the best tube amps made? The best parts for making tube amps exist now, not 50-80 years ago. There are some pretty cool designs out there although its all too common for newbies to rehash 1950s designs. I don't subscribe to the idea that older transformers were better. I... | |
| Hum on Tube Amp - Can't find source Sometimes the simplest answer is the best one. Yes- if more people understood Occam's Razor the world would be a lot calmer place to live. | |
| Hum on Tube Amp - Can't find source @ervikingo 12AX7s trade high impedance for more gain so could be sensitive to a variety of variables. So going to 12AT7s may well solve the issue. I've also found that the brand of tube can sometimes cause hum. For example a phono section I was ... | |
| Hum on Tube Amp - Can't find source @ervikingo I had assumed that since your amps were 'tested at the factory' that they had a clean bill of health. But the first rule of troubleshooting is 'don't make assumptions'. Occam's Razor is always trying to get me to look at the simpler ex... | |
| Ditching Class A Amps due to Heat - Sort of a Poll YOU CANNOT UP THE BIAS QUICK ENOUGH TO CATCH THE MOMENT. I have read the patent and it does not answer this. It cannot. I asked a senior engineer working on my KRS200s how it solves this issue and he could not answer. @clearthink You can easil... | |
| Okay to use RCA adapter on a fully balanced amp? @orchardaudio that will be tricky for a lot of tube preamps. Our preamps can drive that no worries, but our preamps are balanced so its moot... | |
| Ditching Class A Amps due to Heat - Sort of a Poll in the sense that it does what it’s designed to do, prevent notch distortion (the basic reason we want Class A) while reducing power consumption. @axo1989 Just so you know, any class D amp that uses a choke-filtered output (which is nearly al... | |
| Okay to use RCA adapter on a fully balanced amp? @orchardaudio Most preamps can do 5Volts easily as long as the input impedance of the amp isn't an issue! My recommendation is thus to simply try it. | |
| Tube amps and a Stradivarius My question is how do you manage the tubes, they slowly get bad I can't take it, I feel like they start going bad the second I put a new one in and I'm just not noticing it because the bad sound happen so slowly, very frustrating. How do I manage... | |
| Hum on Tube Amp - Can't find source @ervikingo There are a number of AC line problems that can cause diodes to radiate noise which can get into the audio circuitry. Chief among these is the 5th harmonic of the line frequency (in the US, which uses 60Hz, this would be 300Hz). Harmon... |
