| What are the best GaN Amplifiers available today? Which AGD amps did you compare to the Atma - were they the Audion? Would you characterize them as rolled off on top, or just sweet? @blisshifi If you look at the comments comparing the Atma-Sphere amps to the AGD, you'll see that they contradic... | |
| Do Your Speakers have LEVEL CONTROLS or EQUALIZERS? (Vintage or Modern) ??? @elliottbnewcombjr The reason vintage loudspeakers have level controls is because the output impedance of the amplifier was an unknown. So the controls allowed the end user to adjust the speaker to get flat frequency response. They were not there... | |
| Why is solid state more popular when tubes are better? My speakers require a lot of power, so a set tube amp may not be the best choice. @emergingsoul Speakers that need a lot of power have a lot stacked against them! There's something called 'thermal compression' which is a reduction of dynamic co... | |
| Atma-Sphere Class D… Amazing @audioquest4life Into 16 Ohms they will make half of their 8 Ohm rated power. As you already know though, that's plenty for the T1s. You might have to adjust the rear panel controls slightly since the class D has a lower output impedance compared ... | |
| Competitive class D amp suggestions For the Atma-sphere class D amp: Is a preamplifier necessary if only connecting a streamer/DAC to it? The streamer/DAC has it’s own volume control (if I want to enable it). Lumin S1. @veerossi Most digital products can drive it directly with ... | |
| Woofers pumping @tomcarr Swap the channels left for right between the amp and preamp. If the problem moves then the amps are off the hook. Since you tried 2 amps you probably don't have to do this test, but you do have a source which could be the problem. Swap t... | |
| Why is solid state more popular when tubes are better? Tubes are not better. As a technician/engineer that started my career in the days of mil-spec tubes that you can no longer purchase, I can tell you no Class A tube amp can match solid state for linearity. They all produce non-linear amplificati... | |
| 300b lovers How would you compare the sonics of your 300B amp to the the Class D amp you make now? You’re the creator of both, so you’re in the best position to evaluate and compare. I only spent a half-hour of casual listening to the Purifi at the show (and... | |
| 300b lovers Ralph, I sincerely invite you to build your own 300B amplifier. @lynn_olson I did just exactly that some years ago and played the amplifier at a CES in the late 1990s. The 300bs were driven by a cathode follower direct coupled to the grids of t... | |
| SET Lovers, what's the one solid state amp you love(d)? Ralph, I was recommending your GaN amp elsewhere on this site, but his speakers do drop below 4 Ohms I think in the upper bass range, but there are no specs I can find for your amp if it’s stable down to 2 Ohms and what the power output would be ... | |
| Why is solid state more popular when tubes are better? Although I must claim total ignorance, as I didn't past the comment that tubes are warm because they produce harmonic distortion. @pedroeb To be clear, all amplifiers produce harmonic distortion. In general there are two kinds of harmonic disto... | |
| Perplexed on how single driver speakers can cover such a large Hz range My ears say otherwise, but they can’t read. @dlcockrum You might want to go some place where you can hear other speakers. As I pointed out earlier, it makes a big difference what sort of music you play. Any ’full range’ speaker will fall flat o... | |
| 300b lovers @alexberger The 6SN7 can support fairly high current which is why it can make a good driver tube if used properly. It can also make an excellent voltage amplifier (1st stage of gain) since it is quite linear if used correctly. SETs usually do not... | |
| SET Lovers, what's the one solid state amp you love(d)? @soix https://www.epifani.com/ makes some interesting bass amps. Powerful and quite lightweight with some heavy hitters playing with them. You can see where this is going... | |
| Perplexed on how single driver speakers can cover such a large Hz range The old constraints described above for crossoverless single-driver speakers have been nearly, if not totally, eliminated: @dlcockrum This statement is false. I explained why in my prior post. |
