| Which one to choose between two 80K$ tube amps? @shkong78 If you are looking for a speaker that will work with lower powered amps, one you might want to consider is the Classic Audio Loudspeakers Hartsfield (reproduction). John Wolff has done a lot to improve the speaker since it ceased produc... | |
| Audio Research Reference 3 Bypass Caps Question It appears that you are correct, but IMO/IME bypassing coupling caps isn't a good idea. Different caps have different extended series resistance, they have different dielectric constants (even if made from the same material) and as a result the si... | |
| Preamp and impedance question I shouldn’t have use his amps as an example that couldn’t drive those JBL’s 1400 which IS fact and not fiction, "which even he agreed on" way back on the 9-17-2019 and here’s the proof! Ralph's answer https://forum.audiogon.com/posts/1804702 to ... | |
| is the sound of vinyl due to the physical process of the turntable? is it possible to make a dummy record like the nothing record (1978) that was cut with no music just the blank grooves and play that while i run digital audio somehow through the stylus cartridgeNo. The problem is that digital itself has artifa... | |
| What Class D amps will drive a 2 ohm load The output impedance of almost any class D amp is so low that doubling power as impedance is halved is no problem, even into 2 ohms. The limitations are current capacity in the output section, current capacity in the power supply, heatsink capacit... | |
| 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. ... |
