| SET Lovers, what's the one solid state amp you love(d)? Would you say that in your experience with Class D speaker matching is easier or more difficult? Compared to a tube amp, easier! Most speakers are designed to be 'voltage driven' which is to say that the amplifier is supposed to be a 'voltage s... | |
| 300b lovers Since he is no longer with us to defend his design, what do you think are the positive attributes of a differential output stage in a tube power amp? @jaytor Since Lynn isn’t going there I’ll take this one. The advantage is the differential eff... | |
| Why is solid state more popular when tubes are better? "Seems many comments above are talking about artificiality of solid state. Tubes introduce a more realistic Sonic impression versus scientifically created solid state transistor stuff. Tweaking all those electronics to get sound suitable for list... | |
| SET Lovers, what's the one solid state amp you love(d)? In your case with exciting class-D amp success, does this somehow suggest you are eventually planning on shutting down your tube amp manufacturing side of the business, i.e. "are on life support"? @decooney That depends on sales. But if we can ... | |
| 300b lovers @donsachs Yes- those Joseph speakers were nice. I can see 88-89 for smaller speakers. I have a little 5 Watt tube amp I designed for desktop or a bedroom system and I use a pair of Fritz Carbon 6s with it, which are 88dB and I never run the amp ... | |
| Benz Micro Glider Loading Question - any benefit of having the loading terminal option removed from my MP-3? Might its existence allow for noise? No- it can act as an antenna for RFI, but the input of the MP-3 is built to reject RFI. I borrowed a friend's Parasound JC... | |
| 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... |
