| Anybody else waiting for GaN and Purify to have a baby? Alberto PURPOSEFULLY used 400kHz in the first version because he noticed no improvement in sq beyond that. His amps were considered awesome with that frequency. The newer tubes now use 800kHz, purportedly offering increased resolution across th... | |
| GaN Class-D feature packed amplifier from GaN USA themselves limited supply!!! @georgehifi So far as I can make out no-one is being a detractor. Just simply stating fact. Your original thread included a link to Amirm's review. He does not attack it either; instead as I have pointed out, substantiated the idea that its excel... | |
| Anybody else waiting for GaN and Purify to have a baby? The "distortion signature" is just one of an infinite amount of things that effect the sound. It is true that phase shift can cause colorations. But beyond that almost anything else that results in an audible difference is likely due to how it aff... | |
| GaN Class-D feature packed amplifier from GaN USA themselves limited supply!!! Any buyer should be aware that since this board is meant for evaluation, it cannot sustain full power into 4 ohms since it has no heatsinks. For that reason its paired with a Switch Mode Power Supply that limits its 4 ohm power to 114 watts. There... | |
| Anybody else waiting for GaN and Purify to have a baby? That depends on the distortion signature, which seems to be more important than **how much** distortion is present. If "designed properly" (IOW having a similar distortion signature) I would expect the same sound quality too. This is simply becaus... | |
| Help me diagnose a terrible new noise from my tube amp!!! Its only in one channel.So the parts are off the hook. I suspect a problem with the installation still. | |
| Back To Static! @mijostyn I've used a carbon fiber dust brush that is tied to my grounded steel equipment stand via a wire riveted to the brush. I can't say how effective it really is but I don't get pops and noise from static.But it occurs to me that if I can g... | |
| Subwoofer adjustment for each recording Some recordings have a lot of bass. Sometimes when you go to clubs and hear music live, there's a lot of bass. Other times, other recordings, there isn't. I like to play the recording and have it sound like it was made. | |
| Speakers for triode tube amps If you are looking at using a triode tube amp, you might want to read this article- it will help you sort out what you are looking for:http://www.atma-sphere.com/en/resources-paradigms-in-amplifier-design.htmlFWIW most of the speakers mentioned on... | |
| Class D amps seem poised to take over. Then what? So, it seems you have heard Bakoon. How would you describe them? Current drive?Speaking of tintinabulation, I get that fully with AGD. I was referring to the post above mine rather than the amp. Not many people use 'tintinabulation' these days :) ... | |
| What preamp with your GaN power amp? I'm using my Atma-Sphere MP-1 with mine since the amp accepts balanced inputs. | |
| Fourier Amplifiers What Is The History and How Reliable Happen to be considering a pair of Fourier Panthere amplifiers and am wondering what the history is on them. Supposedly these are some of the last production models and are more reliable than previous versions. Do yourself a favor and stay away fr... | |
| Help me diagnose a terrible new noise from my tube amp!!! One other way motorboating can occur is if the coupling caps are a larger value than they should be. If they exceed the frequency poles in the power supply, the amp will be able to modulate the supply and the result can be a low frequency oscillat... | |
| Point to Point vs Circuit Board Some may not but some may. Many times we played beat the proto...This is why I was careful to use the word 'properly'. | |
| Help me diagnose a terrible new noise from my tube amp!!! Now, for context, I replaced the coupling caps on both of these monoblocks a week ago (with caps to designers spec) and I may have screwed up the soldering somehow. But I played these amps for several days at normal bias without any issue unti... |
