| Which one to choose between two 80K$ tube amps? explains (to some extent anyway) what/why I heard differently between my SET (class A triode 300b) and my 100 watt push pull( class A/B pentode tubed 6550) amplifiers. Some degree of 5th harmonic distortion presence.Yes- nearly any amp along t... | |
| Damping Factor - Interesting article I am not saying a huge improvement, but the low DF will in many cases be better.That's an interesting idea- but I suspect one that has not seen a lot of study. | |
| Which one to choose between two 80K$ tube amps? But, is 3rd order harmonic distortion as easily/naturally tolerated by the human ear as is 2nd order harmonic distortion which is quite well tolerated. Some would say that in fact 2nd order Harmonic distortion is congruent with human hearing.@c... | |
| Suggestions on Integrated Amp./Seperates to Run my Klipschorns all Klipschorns are 'corner horns.'I have probably conflated 'Klipschorn' with any Klipsch that employs horns...I had a set of these (1960s) that I sold about 5 years ago. They worked great with our amps. Our S-30 seemed to be the best bet on that... | |
| Preamp and impedance question And this is the reason why Ralph Karsten’s big Atmasphere’s monoblocks that my friend had, could not drive the bass of the "so say" easy load, high efficiency (90db), easy impedance load (8ohms) of the JBL 1400 Array speakers, because of the added... | |
| Damping Factor - Interesting article What is likely to product worse cone breakup, a high DF or a low DF?To my understanding, cone breakup has nothing to do with the amplifier. | |
| I can prove your room is bad This method does not demonstrate a need for you to improve the room. You pass.FWIW, I've used the Classic Audio T-3s in a variety of rooms and I can safely say that in all of them- and without treatment of any kind- the speaker has *always* sound... | |
| Which one to choose between two 80K$ tube amps? @charles1dad The Berning amplifier in question can run feedback or none; being SET its distortion signature is based on a quadratic nonlinearity (2nd harmonic). In order to have a cubic nonlinearity (based on 3rd harmonic) the amp has to be entire... | |
| What Class D amps will drive a 2 ohm load @noble100 Yes, Bruno has been able to design class D amps with loop gain north of 75dB!!He did acknowledge to us that there was a typo in one of his papers when we pointed out a math error regarding the oscillation criteria. It was not an error in... | |
| Damping Factor - Interesting article How does damping factor apply to a zero feedback amp like an ayre .Generally speaking, the output impedance of a solid state amplifier can be so low with respect to most speakers that it can behave as a voltage source, even if it has no feedback. ... | |
| Suggestions on Integrated Amp./Seperates to Run my Klipschorns As others have pointed out you don’t need a lot of power but you do want clean power. The design of the speaker is such that many solid state amps will sound brighter and harsher than normal (this is part of why horns got a bad name; nothing to do... | |
| Damping Factor - Interesting article Every amplifier has some feedback. Even emitter resistor is a form of local feedback. The problem with global feedback is, that it corrects with a delay (phase shift from input to output). This delay produces overshoot in time domain (odd ha... | |
| Damping Factor - Interesting article This is too simplistic a view, and I was thinking specifically just related to the basic output stage which does typically behave much like a voltage source, and is usually configured as a voltage follower, and with a light load (lighter than a... | |
| Damping Factor - Interesting article Another dimension of DF not often discussed is having high DF, and high current through the treble. While conventional speakers tend to have their low points in the mid-bass, where most amps have the highest DF, ESL's are essentially capacitor... | |
| Tube Preamp with Solid State Amp? I'm also searching but I also need XLR inputs on a tubed line stage/preamp as my Nagra MPA has only XLR's.Atma-Sphere, BAT, Aesthetix... |
