| Ripple current Q for amp capacitors @tester007 Sorry, I've never done it. When I replaced them once I just turn power on.@atmasphere would know, I'm sure, perhaps he can chime in. | |
| Ripple current Q for amp capacitors @tester007 7mOhm ESR @ 120Hz is an internal impedance of the capacitor (Equivalent Series Resistance) measured at 120Hz - lower is better. It represents losses in capacitor. 29.3A @ 120Hz is the max charging current at 120Hz - higher is better... | |
| Distortion Distortion Distortion @bjcatanzaro Mine is DAC3 + AHB2. I agree - it is as clean as it gets. The only negative part, according to many, is the same thing I praise it for - lack of distortions. Many amps add euphonic second and third harmonics covering unpleasant ... | |
| Just got a new power amp @atmasphere I agree, "Fully Balanced" design doesn't have to be better - net result is what counts. There are many imprecise popular or marketing terms in use, why to argue. I noticed that many great companies still use erroneous "watts RMS" an... | |
| TV Sound Compression @mahler123 My older Sony had no setting for that, but Bravia 9 (and likely all Bravias) has it. I wan't to know who is compressing - TV station or TV itself. Perhaps it is TV station and TV compresses even more for better sound on tiny speaker... | |
| Just got a new power amp @atmasphere Tube design is your domain so it is not wise for me to argue, but grounding tap of transformer’s secondary won’t make current return to GND. Transformer output is balanced, but stage driving primary might be not with one transformer... | |
| CD's or Vinyl? To add LPs I would have to buy decent TT (not cheap) and phono section. For money spent I could replace my current speakers. Keeping both LP and CD is not the best way to go IMHO. I decided to go with CD, since LPs are more expensive, with smal... | |
| Just got a new power amp @atmasphere I replaced second "S300" with "such amplifier" to make it general. To me something that is "Fully Balanced" has all stages, including output stage, balanced. One criteria of balanced output is lack of GND return current. | |
| Just got a new power amp @atmasphere Amplifier in question PS Audio S300 has only balanced input with single ended stages following. I don’t believe that adding, for instance input transformer, makes any amplifier "Fully Balanced". In my opinion such amp is an amplifi... | |
| Just got a new power amp @atmasphere Perhaps my definition is too restrictive, but IMHO amp with one of speaker terminals at GND is not "Fully Balanced" Amplifier shown on the first schematic here looks "Fully Balanced" to me https://www.hifi-amplifiers.com/en/tonewinn... | |
| Just got a new power amp @atmasphere Fully Balanced, in my opinion, would require two output stages - in your case two Push-Pull stages, which probably wouldn't make much sense. If we call S300 amplifier "Fully Balanced", then do we call Emotiva XPA-1 "Fully, Fully Bal... | |
| Just got a new power amp @atmasphere "Fully Balanced Amplifier" is in my opinion an amplifier that consists of true balanced input stage, like transformer or instrumentation amp, followed by two amplifiers - each for one leg/phase of the signal. Speaker is connected be... | |
| Cannonball Adderly - Know What I Mean @bigtwin I listen to samples and I'm Gettin' It Not only good Jazz but super sound quality. It sound like there is no compression at all. Brass instruments have huge dynamics in treble. Great performance and sound - thanks again. I have fe... | |
| Just got a new power amp @cleeds He talks about benefits of balanced cables and differential inputs. It has nothing to do with "Fully balanced power amplifier" vs power amplifier with balanced differential inputs. I will leave it at that. | |
| OT: Espresso machines @dman777 Linea Mini is very interesting machine. It has unusual design being heat exchanger machine with two boilers. I guess professionals believe that brewing water has to come fresh. They call water in the boiler "dead water". In my ECM M... |
