| Amplifier recommendations for 86 dB Sensitivity Speakers @mamifero I forgot some things. There is a phenomena known as 'thermal compression' in loudspeakers. Its where the voice coil heats up with bursts of power through it. The more it heats up the more compression. This is why you read about more e... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? So if you listen mainly listen to (an amplified) rock or electronic music, push-pull would be fine. But if you want to fully enjoy an acoustic music, you will do that better with a set amplifier. @niodari This statement is misleading at best. E... | |
| Amplifier recommendations for 86 dB Sensitivity Speakers @mamifero The speakers you have in mind are 86dB and 4 Ohms. Sometimes its worth considering what this looks like in terms of efficiency rather than sensitivity, since efficiency is stated in Watts rather than Voltage. This is especially importan... | |
| SS amp or receiver that sounds like Tube Amp Any other and hopefully newer SS gear sounds like a quality tube amp? Tube amps usually have a natural sound and lots of detail with high clarity. @jimbennet There are class D amps out there now that sound very much like a good tube amp. I use ... | |
| Allnic OTL/OCL Phono vs Allnic DHT To do this, Allnic uses a “floating power supply circuit”, a design that deals with the issue by not creating any DC potential in the first place, or such a small potential that it is harmless.” @kevalinaudio We have two patents concerning a me... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? Virtually all the amplifiers on the market are based on a push-pull symmetry model. The push-pull symmetry topology has no particular basis in nature. Vacuum tubes and transistors don't either. This is a red herring. I don't normally disagree ... | |
| Amplifier Paradox…and more! @tksteingraber This article is full of misinformation. I’ll point out a few: Class A designs are known for sweetness and warmth, Class AB offers a balance of power and finesse, and modern Class D amps bring speed and efficiency without the ste... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 The Z-565 is the output transformer. Its ultralinear taps are supposed to be at 25%. It might be worth measuring their impedance to see if that would work better as a plate to plate load. Off the top of my head I can't say since the imp... | |
| Allnic OTL/OCL Phono vs Allnic DHT never heard the sound of OTL phono amps. @joeycastillo nearly all phono sections are OTL; OTL stands for 'Output TransformerLess'. Since we have been making preamps with direct-coupled outputs (so OCL and OTL) for decades now, we had consider... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? They subjectively have a faster attack (particularly noticeable on the reeds in oboes and clarinets and more organic reverb (best heard on good piano recordings).While @atmasphere is firmly advocating balanced connection I have so far been unable... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? @yoyoyaya I remember hearing something like that too. The thing about distortion is we don't put a weight on the harmonics generated. The higher ordered harmonics are the ones that really mess with the ear- the 2nd and 3rd, hardly at all. But ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 I applaud your interest in experimentation. Triodes will give a pleasant distortion. But if you want to maintain the feedback you'll need another stage of gain. Another consideration is the tube in triode mode will want to see a differe... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? It is a two camp showdown one camp being group 1, who evaluate through solely having used their experiences of End Sound produced and the impression made on them. The other camp, group 2, who are much lesser in their number than group 1, and are... | |
| Would You Rather Own A Good SET Amp, Or A Great Push Pull Amp? 845 SET can drive some speakers not often associated with SET, power supplies with these quite substantial, around 900V plate voltage with these. With the right speakers a nice 300B amp running top tier 300B tube like the new Western Electric is ... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? What are your thoughts on reducing the bias a bit on the voltage? @rankaudio The power tubes can handle it well enough. But that will affect the distortion signature of the amp but by how much is hard to say. my tech and I will be adding a sw... |
