| Ditching Class A Amps due to Heat - Sort of a Poll YOU CANNOT UP THE BIAS QUICK ENOUGH TO CATCH THE MOMENT. I have read the patent and it does not answer this. It cannot. I asked a senior engineer working on my KRS200s how it solves this issue and he could not answer. @clearthink You can easil... | |
| Okay to use RCA adapter on a fully balanced amp? @orchardaudio that will be tricky for a lot of tube preamps. Our preamps can drive that no worries, but our preamps are balanced so its moot... | |
| Ditching Class A Amps due to Heat - Sort of a Poll in the sense that it does what it’s designed to do, prevent notch distortion (the basic reason we want Class A) while reducing power consumption. @axo1989 Just so you know, any class D amp that uses a choke-filtered output (which is nearly al... | |
| Okay to use RCA adapter on a fully balanced amp? @orchardaudio Most preamps can do 5Volts easily as long as the input impedance of the amp isn't an issue! My recommendation is thus to simply try it. | |
| Tube amps and a Stradivarius My question is how do you manage the tubes, they slowly get bad I can't take it, I feel like they start going bad the second I put a new one in and I'm just not noticing it because the bad sound happen so slowly, very frustrating. How do I manage... | |
| Hum on Tube Amp - Can't find source @ervikingo There are a number of AC line problems that can cause diodes to radiate noise which can get into the audio circuitry. Chief among these is the 5th harmonic of the line frequency (in the US, which uses 60Hz, this would be 300Hz). Harmon... | |
| Hum on Tube Amp - Can't find source @ervikingo Yes. | |
| Tube amps and a Stradivarius I still don't think the best class D amps are as smooth and holographic as the best tube amps, but they are getting better. @invalid IME as long as you have the right amp, class D can be every bit as liquid and smooth as the best tube amps. B... | |
| Hum on Tube Amp - Can't find source @ervikingo Get yourself something called a Digital Voltmeter. Set it to the AC scale and plug the probes into your AC power. Keep an eye on the voltage; when the hum shows up look at the voltage and see if its changed. Or you could also use one... | |
| Okay to use RCA adapter on a fully balanced amp? Here’s the part that concerns me about this amp possibly not having a "true" differential input, despite earlier verbiage: If a balanced connection cannot be used, note that the amp cannot be driven to full power from a 2-volt single-ended outpu... | |
| Tube amps and a Stradivarius Tube amps are not technically as accurate as solid-state but they sound more musical, I would submit that they sound that way because of the ring of the tubes just like the reverb of the Stradivarius violin. I believe the vibration of the sound f... | |
| Purifi v Gan amps? @noske Ralph’s class D amps (Gan) have input of 100K ohms - this is good. They are only suitable for 60hz/120 V supplies. This makes them unsuitable for about 6 billion people. This statement isn't correct- our class D can run on 50Hz/235V no... | |
| Okay to use RCA adapter on a fully balanced amp? true fully balanced differential amplifier from input to output. @blkwrxwgn , you should be able to drive the amp single-ended using an adapter. I would expect that your amplifier would sound the same driven balanced or single ended based on t... | |
| Vandersteen Forum @gdnrbob +1 FWIW I didn't notice that the forum was for Vandersteen owners only! | |
| Vandersteen Forum I was trying to answer a question on that forum and the moderator @ctsooner blocked my posting privileges indefinitely. This meant I could not ask him what the problem was. I am very careful to not violate forum rules on any site and I know I di... |
