| Are you pairing Tube Preamp/Line Stage with Class D Power Amp? Maybe more folks have come around to Class D and have played with putting tubes in front of one. They have 😀 | |
| Audio valve preamp The first thing to do is swap the interconnect cables at the inputs of the power amps, left for right. If the problem moves its either the cables or the preamp. If the preamp stays put is either the amps, speaker cables or speakers. | |
| The Best Preamp is no Preamp? This has been an on-going topic for a very long time! @phantom_av makes a good point about the quality of the line stage; IME if a passive sounds better its telling you something about the line stage you used for comparison. IMO line stages have b... | |
| For the anal retentive audiophile...a mains frequency tester For the anal retentive audiophile...a mains frequency tester You might as well include some test equipment from Fluke Instruments so as to detect the presence of harmonic distortion on the AC line. The 5th harmonic in particular can be quite pe... | |
| Benz SLR Gullwing, not sensitive to loading? Does anyone else here has a Benz Gullwing (or LPS = same generator) wich does not react to input impendance? I's on a Clearaudio Ovation with TT5 arm. My phono stage is a Graham Slee Reflex C in wich I just soldered 47kOhms resistors when I got t... | |
| Conditioner vs. Surge protector @ei001h , @carlsbad has given you excellent +1 advice. | |
| The Best Preamp is no Preamp? Thus, the only explanation for this is that the brain “likes” certain types and amounts of distortion. A more complex topic is how distortion from different parts of the chain interact. @tangramca There is more than one explanation! If you've e... | |
| Integrated tube amp vs Tube amp? An additional advantage of going with separates is you can have the power amps be monoblocks. This can allow you to place them closer to the loudspeakers, allowing for shorter speaker cables. With tube amplifiers in particular, this can really hel... | |
| Power regeneration - good idea? PS audio? It would seem the existence of large capacitors inside an amplifier would mitigate the impact of a voltage decline temporarily. @jumia This is correct only if its for a second or two. If longer, a few minutes or hours then no. If the voltage is... | |
| Researching SET Amps what’s important in an SET amp: 1) Power tube mating to the proper speaker, and 2) Design and manufacture of the transformer. The first question isn’t a thing. You don’t mate a power tube to a particular speaker, unless you’re talking about to... | |
| The Best Preamp is no Preamp? Sound reinforcement systems don't have pre-speaker-amp "preamps" as a concept even. Of course they do! The preamp is known as a 'mixer'. ******************************* There are four functions a preamp provides: 1) provide input switching ... | |
| Power regeneration - good idea? PS audio? An amplifier would have to be deficient, defective, or broken for this claim and assertion to be accurate. A lot depends on the amplifier! In this case it was a tube amplifier. Tube amps have a filament circuit and when the voltage on the fila... | |
| Tube Amp settings: Triode vs UL; 8 ohm vs. 4 ohm ? Utralinear uses a very specific point on the primary winding where the screen tap is placed in order to get the best linearity- in which case the linearity curve looks like any DHT triode. For triode operation the load on the tube changes (usuall... | |
| The Best Preamp is no Preamp? If you run short cables you can get away with this. But if you have monoblocks (which are useful for keeping your speaker cables as short as possible) then no so well. I've found that using balanced connections to the monoblocks and having short s... | |
| Power regeneration - good idea? PS audio? Is there that much of a difference between 117 V and 121 V coming through your system? I've seen a 3 volt change like that rob an amp of 40 watts of power. But a conditioner does more than that- a good one will provide a clean AC waveform, thus... |
