| Why is solid state more popular when tubes are better? Could you please enlighten us, not as to brands or products so much as to what traits those solid state amps have and what ICs/transistors they use? e.g., are there transistors that introduce the rich mellow sounds of even harmonics without other... | |
| SET Lovers, what's the one solid state amp you love(d)? I replaced my tube amps with a class D amp and no downside in my system- its just as smooth and revealing as the tubes were- no harshness or brightness and good bass impact. I'm really convinced that tube power amplifiers are on life support; why ... | |
| 300b lovers The previous point about Class A operation in a differential stage still holds: what happens when more than 100% of the current programmed in a current source is exceeded? It won't if the circuit is properly designed! The real question is what... | |
| Benz Micro Glider Loading Perhaps Ralph is correct about it not making a difference in his preamp. @voolston You can imagine that if I'm aware of this issue facing all phono sections that we would make an effort to see to it that our phono section didn't have a loading ... | |
| Perplexed on how single driver speakers can cover such a large Hz range @marshinski15 The simple fact is no ’full range’ driver is really full range. Most struggle to get below 50Hz in an optimal enclosure. So if you want full range you will need a subwoofer. They also are beamy on top. So only one person can sit i... | |
| 300b lovers @lynn_olson You might want to read this article: The Power Paradigm Most zero feedback tube amplifiers are Power Paradigm devices. Regarding some of your comments in your post above: How an output section behaves was not the topic when you b... | |
| 300b lovers A differential circuit has a current source or high-value resistor in the common cathode (or emitter) circuit, which is why they are called "long-tailed pair" in the literature. This forces differential operation, but has a limitation because the... | |
| Why is solid state more popular when tubes are better? If someone here can point me to a SS Amplifier that will sound EXACTLY like my AUDIO NOTE VINDICATOR SILVER 2A3 Amplifier...I'm all ears!!! 😎 @voodoofunk You can't even find another 300b or 45 based amp that will do that- for that matter probab... | |
| 300b lovers @cloudsessions1 Thanks for the links! Given how much Bruno Putzeys has written about this topic it was my assumption that all of his designs conformed to his ideals. Assumptions can get you into trouble... I'm Ok with the agree to disagree. I've... | |
| Why is solid state more popular when tubes are better? do you have distortion measurements that you can share with us comparing your tube and class-D amplifiers? In general our class D makes about 1/10th the distortion of our tube amps at full power. At lower power levels its much lower, since the ... | |
| 300b lovers [QUOTE="Helom, post: 32394540, member: 71602"]I suppose if I was specifically seeking a lightweight class D amp then I would probably give the Atmasphere model a try. I suspect most class D manufacturers are more concerned with cost savings and s... | |
| Why is solid state more popular when tubes are better? Atmasphere manufactures Class D amps to so he's invested in the technology (I haven't heard his Class D mono amps but I imagine they sound fine) so there's that, and although he claims they measure like tube amps, I'm not sold. 😀 In the past th... | |
| Why is solid state more popular when tubes are better? @phusis I can't speak for other class D amps although I've heard a few that are really quite good. Class D amps vary in sound more than from the worst to best tube amps. Some really can't be taken seriously. Some are really boring. And some are am... | |
| Why is solid state more popular when tubes are better? Many people like solid state. It happens to be more convenient. But that's not why everyone likes it better. Not everyone agrees. I'm glad not everyone agrees. Leaves more tubes for me. The problem is there is plenty of S. S. and plenty of... | |
| 300b lovers Why buy an high-end audiophile component, with audiophile pricing, made from off-the-shelf $5 parts. @lynn_olson It might be because those parts work... Tube gear costs a lot because transformers and vacuum tubes are inherently labor-intens... |
