| Balanced Inputs Balanced inputs often offer 6dB increased gain. @cleeds @charles1dad This is only true if the equipment supports the balanced standard. Otherwise the gain does not change. I don't think any of my gear is truely balanced. I have a modest sy... | |
| AGD Audion GaN Class D In The House If I had the scratch I’d go with AGD just because the designer made his amps upgradeable, which is huge to me especially since GaN amps are in their relative infancy. @soix FWIW our amp is easily updated too. | |
| Class D with high efficiency speakers My question is, does anyone have any experience of running a new Class D GaNFET amp into high efficiency / high impedance speakers? @rocketiii My speakers are 98dB and 16 Ohms. I've been running our class D GaNFET amps on them the last year and... | |
| Need help diagnosing a preamp problem Currently I am experiencing intermittent right channel in/out when cables are correctly connected. I have reversed connections several times. @clio When the channel is out, try wiggling the interconnect cables, on the offending channel, to see... | |
| Speakers that are good with tubes It does not have so be 8 ohms or above. My speakers are 4 ohm, but they are very, very flat and very well designed. I bought them to use with an ss amp. The first time I heard them with a tube amp, I promptly sold the ss amp. The statement w... | |
| What Does It Take To Surpass A SME V? I never got to see the exhibit in New York but I have a beautiful hardback of it with pictures of every bike. A group of us misfit bikers took the train to the Chicago and got a special showing at the Field Museum. A year or two later I went to... | |
| Why don't higher end amplifiers come with a separate power chassis? Seems to me the amplifier is deserving of a separate power box and all the rational to not do it doesn’t make sense. The impact on sound could be huge if done properly. @emergingsoul Keeping the power supply as close to the output section as po... | |
| Which Line Level, Balanced Preamplifier? FWIW the first balanced line preamp made was the Atma-Sphere MP-1 way back in 1989. Whatever preamp you get, its useful to know there is a standard for balanced line hookup, known as 'AES48'. I've found over the years that most balanced line prod... | |
| When were the best tube amps made? I have directly compared the Linlai 6sl7 withe the ken rad vt229 and I can say the Linlai elite do sound better, now hopefully they last just as long as the ken rad. Yes- that's the one thing... | |
| Impedance and Sensitivity My problem is that I do not know how to relate amp input sensitivity to preamp gain. One Volt less of amp input sensitivity equals how many preamp dB? In preamps, 6dB one way or another is a doubling or halving of the voltage. From 1 to 2 volts... | |
| When were the best tube amps made? Which modern 6SN7 are better than NOS? I currently use Ken-Rad VT-231 from the 1940s in the input stage of my integrated 300B SET. They are not the most expensive NOS but still to change the pair of these tubes is expensive for me. The Linlai 6... | |
| Impedance and Sensitivity @dsper You have put your finger on why lower powered amps also have less gain, since its an expectation they will be used with a more efficient loudspeaker. A higher powered amp usually needs more gain since its more likely to be used with a low ... | |
| Peachtree GaN 1 Beta As the GAN1 is a PWM amplifier controlled by digital timing signals mainly, and not attempting track an analoig signal with high precision as would be required in a Class D amplifier, would the GAN1 be less sensitive to some of the issues you hav... | |
| Peachtree GaN 1 Beta @donnylovely There's no hate involved. If that were so my posts would be a lot different 😉 The trick on the internet is to not take things personal. That's when you get into trouble. I don't claim to know everything either- but I've learned that ... | |
| When were the best tube amps made? what are the tubes nowadays like? I keep getting the impression that NOS are the best @lohanimal That depends on the tube. I think most of the NOS tubes are better than a lot of the new pentode power tubes.... but there are some excellent 6SN7s... |
