| Paul Klipsch was right - What the world needs is a good 5 watt amplifier I cant tell you how many components I bought in the last two "Covid Years" that had great reviews/measurements by "Audio Science Reviews" that I had to return because they were unlistenable. IMO too little attention is paid to distortion spectr... | |
| Let me end the Premp/Amplifier sound debate ... @holmz +1 My thoughts exactly. that Stereophile nonsense caused me to suspect Mr. Carver so many years ago; the latest debacle with an amplifier that can't make anywhere near full power sealed the deal IMO. And if you want good S.Q. buy first an... | |
| How to tell the current from the amp So there is no one measurement available to indicate the “current” capability? I don’t have electrical technical back, and I feel this concept is being mystified… @dragoncave The problem you’re up against is marketing. Often solid state amps ... | |
| Let me end the Premp/Amplifier sound debate ... It's not that the distortion signature is too small, it's that no one measures it. No SPL meter is going to be better than ±0.1db @ 85dB. It likely has a nonlinear response. In absolute terms, it's not even close. It gets measured alright. But ... | |
| Let me end the Premp/Amplifier sound debate ... The question was about current and voltage. The current and voltage cannot be the same if the harmonics are temporally shifted relative to the fundamental. Since almost agree that tubes sound different than solid state, then what makes up the ... | |
| Let me end the Premp/Amplifier sound debate ... This series of frequencies into an 8Ω load resistor gives an idea of the Phase Shift in a tube amplifier output transformer @ 10W RMS. The ear is extremely sensitive to phase, but hardly anyone mentions it. The ear is only sensitive to phase wh... | |
| Let me end the Premp/Amplifier sound debate ... FWIW, I've never measured a tube amp output voltage into a loudspeaker that was anywhere close to what an SS amp delivered into the same load... going back to the 70's. Admittedly, it's a small sample, and largely irrelevant as measurements mostl... | |
| Let me end the Premp/Amplifier sound debate ... To date, I've yet to see a tube amp measurement that does not look similar to the Black Line into the Stereophile simulated speaker load. Many speakers' impedance curves make the Simulated load look like a resistor. Have you looked? As long as ... | |
| Let me end the Premp/Amplifier sound debate ... Speaking from my personal experience, I believe the measurements we use as standard do not tell the whole story. Not at all. The only reason this happens is that all the measurements are either not published or simply were never made. One of t... | |
| Let me end the Premp/Amplifier sound debate ... Voltage from a tube amplifier OPT will vary considerably depending on the speaker impedance at the test frequency. @ieales This statement is incorrect. This amp uses about 15 dB of feedback, allowing it to behave as a voltage source with most s... | |
| Help with choosing sub-woofers please The 14 foot wave takes 12 milliseconds to pass my ear. Is that fast or slow? My MLs are flat at 80Hz and the bass there is pretty tight, not an unrecognisable reverberating mush. @clearthinker Don't worry about the speed- that has nothing t... | |
| No more "High End" for me...Back to Reality Audio what do you think lightning strikes cause?? In my world lightning strikes are different from power surges, which are caused by the power company. One way a power surge can occur is if there is an interruption of power, the magnetic field in th... | |
| Help with choosing sub-woofers please Many say bass isn’t very directional below about 50Hz. But bass heard above that on the MLs is certainly directional * To what extent will the sound deadening deal with room modes? Some say bass waves go straight through wall treatments back to ... | |
| No more "High End" for me...Back to Reality Audio But it sounds FANTASTIC...You can't believe 8 watts into KEF LS50 Metas would even work, nevermind sound like it does.....Something is wrong with the whole High End HiFi picture..... @rbertalotto Not really: there is a reason Nelson Pass name... | |
