| D-Sonic peak current output compared to other Simon, Are you saying that your amplifier can produce peaks of 65Amps? Or are you saying that when shorted, your power supply can produce a peak of 65Amps for half a second?Both are impressive specs, however the former is not credible. It suggests... | |
| What tube pre amp match up with a solid state amp A good reason to go balanced is the advantage of being able to run really long interconnects, so you can place the amps close to the speakers and avoid sonic degradation on account of the speaker cables.The balanced line system was created to get ... | |
| What's a properly lit 6SN7 tube look like? Some 6SN7s are properly lit when you can only see something from the top. A lot depends on the particular brand and vintage! | |
| Easy biasing Tube amps Atma-Sphere is part auto-bias and part manual. IOW the bias is automatic but you still use the onboard meter to set the DC Offset (there is a single DC Offset control because the output of the Atma-Sphere amps is direct-coupled). Drift is low, so ... | |
| Listening fatigue Another thing that is well-known for causing listener fatigue is odd-ordered harmonics in trace amounts, something that is common to most transistor gear.This will get more pronounced as volume is increased.The reason is that the ear uses odd orde... | |
| 45 Type Push/Pull Phil, if you can't see it on the scope, that does not always mean it does not exist. But it does mean that its pretty slight- if you have a really high bandwidth scope (200MHz and higher) that stuff usually shows up pretty well if its there.Howeve... | |
| 45 Type Push/Pull Thanks Phil for your reasoned response. I am basing my comments on the simple observation of the amps themselves on the bench. I've seen crossover and notch distortion in transistor amps (which in some cases it was possible to correct by adjusting... | |
| D-Sonic peak current output compared to other At the end is the music that matters. Your amps sound great, so do Parasound amps and many other amps out there with totally different designs.Isanchez, this quote above really says it all- and also points to the fact that current is in fact not w... | |
| 45 Type Push/Pull Phil, even if you run class AB1, you still don't run the risk of any crossover artifact, since at lower power levels where the crossover artifact might occur, the tubes are in the A region.What I have found is this is more a problem relating to so... | |
| Triode mode vs pento mode It depends entirely on how well the output transformer is designed. However if you caught some of my comments earlier about the actual correct tap point of the screen taps, if the transformer is really set up correctly there will be no need for tr... | |
| D-Sonic peak current output compared to other There are a number of things in the excerpt above that are patently false (despite the source) but are indeed widely-held opinion in the form of myth.For example the ability to play deep effortless bass has nothing at all to do with the ability of... | |
| Tube Amplifier for Thiel Unjc, how big is your room? Is it lively or more dead? That will say a lot about what you can get away with. | |
| Triode mode vs pento mode Johnsonwu, only if they are properly designed for it. Pentode mode operates at a higher impedance than triode, so the transformer needs to be designed to allow that. IOW you can't just convert an amplifier by rewiring the output tubes in triode mode. | |
| 45 Type Push/Pull subtle push-pull crossover notch grungeThis is something that should not happen with a DHT p-p design. Crossover or notch distortion are artifacts of transistors and designs that are not class A, unless there is a serious design defect.I have a pa... | |
| D-Sonic peak current output compared to other Not sure I buy the explanation in the video. It needs elaboration to know what he is trying to say. |
