| Power regeneration - good idea? PS audio? would you recommend plugging your amps, which i own, into a ps audio regen? It depends on the amps and the model of regenerator. If one of our smaller amps and one of the bigger regenerators, yes- certainly worth a try. The regenerator should b... | |
| Looking To Match A Tube Amp With A Pair Of Audio Note AN-K/Spe Have certainly decided that a 20-40W pentode design is a good path. Keeping in mind the K's are in a 12x26 room go with KT 66, 77, or 6L6 for an "EL-84 tactile and immediate" kind of sound? If it were me I'd be looking for an amp with Ultra-Lin... | |
| Paul Klipsch was right - What the world needs is a good 5 watt amplifier FWIW front row center at an orchestral concert can easily be over 100dB on peaks. There are a lot of things that can cause harshness in a system when you try to run the volume at realistic levels. Early side wall reflections are interpreted by t... | |
| Paul Klipsch was right - What the world needs is a good 5 watt amplifier My peak levels approach 100db + and it does not hurt me in any way. My ears check out fine, as I have annual check ups. This is such a very important aspect to music reproduction for me. +1 My point exactly. | |
| Paul Klipsch was right - What the world needs is a good 5 watt amplifier Measurements don't tell you how a piece of gear is going to sound, no matter what brand, especially not measurements from REW Sure they do- but for that simple reason you rarely see them , and I've found that many people don't understand what t... | |
| The Growing Challenge of Buying NOS/NIB Tubes @pesky_wabbit The JJ 12AT7 can be quite nice. But like any production tube, they aren't all the same. Some are noisy, microphonic and those have to be returned. Put another way, if you want some nice JJ 12AT7s you'll have to buy more than you need... | |
| 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... |
