| 300b lovers A current source could replace the resistor, but in practice, the performance is very similar to a current source, so it’s rarely done even in modern amps. Usually in a differential amplifier, the plate resistors are matched if both halves are ... | |
| 300b lovers @charles1dad My point was addressing a comment made earlier by Lynn about overshoot in amps employing feedback; simply that if you do it right its not a problem. The OP mentioned using Spatial Audio Triode Masters who were a dealer of ours and hav... | |
| 300b lovers I changed the load resistor to 120KOhm, and the overshoot decreased by amplitude and attenuation time. But still, there is a notable overshoot. I measured a frequency response and there is a hump +1.7dB at 35KHz. There is -3db at 19Hz and 47KHz. ... | |
| Class D amplifiers. What's the future look like? As well as other new applications of technology such as Westminster Labs sliding bias voltage Class A cool running higher power solid state amps? They may well function superior to Class D amps. The issue has been for the last 70 years and ... | |
| Speakers 10 years old or older that can compete with todays best, I digitize my turntable and use digital RIAA correction which is more accurate than any analog circuit. I am curious about this. The RIAA pre-emphasis is of course done with analog components; as a result is not the ideal but instead a modified... | |
| XLR cables for a reasonable price? Yes, we can agree that it seems that's your only point. I'm not sure that I agree with the premise that the cables in my mostly-ARC system represent a "veil" on the sound +1 Some have called me a 'cable denier' on this account. The easy way to... | |
| Class D amplifiers. What's the future look like? A crappy or over hyped review shouldn’t change anyone’s desire to audition or dump a component. A true test of a component is how it sounds (gels) within your system and to your ears. @lalitk You got that right. If the manufacturer’s, distribu... | |
| XLR cables for a reasonable price? You understand that AES48 is just one "standard," correct? There are other ways to design balanced components and choosing an alternative doesn't mean the standard you so cherish is "ignored." @cleeds You are correct to a point. There are other... | |
| XLR cables for a reasonable price? As if there were no other good amps or engineering approaches. There are, and many. I believe that manufacturers and dealers should be honorably dismissed. It doesn’t matter how much knowledge and skill they might have, this is not a proper place... | |
| Class D amplifiers. What's the future look like? I think he might need to work on his business model 😁 @soix FWIW Eric uses a set of DeVore Fidelity speakers in his system; the same that he used for the M-60 review. IIRC the o/96s. | |
| XLR cables for a reasonable price? And then there's the fourth way, which I think may be the most common: use an operational amplifier. ("Op-amp.") They can be fully discrete, and seem to be the approach used by many, such as ARC, for example. @cleeds Opamps can generate a bala... | |
| Class D amplifiers. What's the future look like? when i just look at his D with the chassis open, it ain’t looking like much to me. Class D, done properly, is never going to look like much. Its very different from a tube amp in that regard!! The biggest issue class D has to contend with is no... | |
| XLR cables for a reasonable price? What you seem to be implying is that the internal wiring in a balanced amplifier, or preamp is not important either. @tonywinga If this comment is directed at me, no, I did not imply that at all! The quality needed internally is very dependent ... | |
| XLR cables for a reasonable price? All XLR cables sound the same? A fantasy that we all wish were true. I thought that based on a lot of talk on these forums until I started trying out some different XLR’s in my system. Then I bought some of the top of the line Purist Audio Design... | |
| XLR cables for a reasonable price? This is absolutely false. Single ended or balanced the first most important thing is the quality of the wire. How much this affects the sound quality depends on your components. In general consumer products, not at all, budget components most lik... |
