| The 300B World The rectifier tube should be a consideration in 300B SET build. In a traditional single-ended 300b amp the current draw is constant, from idle to full power. That means the voltage drop across the rectifier is constant too. If you are hearing d... | |
| Power conditioner wire gauge? Serious issue Since the action of conditioning the power must consume some of it, the conditioners of which you speak presumably have power supplies of their own to make good the loss. @clearthinker They do. The PS Audio, if I understand correctly, employ... | |
| Is a noisy tube a bad sounding tube When I turn the gain up to maximum there is some minor tube noise I can hear when I put my ear to the speakers on side only. If its only that loud you have no worries. @tablejockey gave you good advice. | |
| Audio Research Reference 150 - buzzing input transformer Is there anything that can cause the transformer to overheat and melt inside? The noise was caused by a vibration of the plates inside the transformer. Does anyone know how hot the input transformer can get? @filipm To the first comment (so... | |
| Concerningly loud pops in vinyl playback I've put it on the phono stage for now (along with tonearm ground) BUT being a Hagerman Trumpet, it takes DC from a SMPS wall wart that's 2 prongs. So there's no connection to earth ground. So I guess that's kind of a bummer if the intention of t... | |
| Power conditioner wire gauge? Serious issue All power conditioners steal power. @clearthinker This isn't entirely correct. A good power conditioner will do nothing of the sort. Many 'conditioners' are passive devices and so probably do limit current (and so have a voltage drop) but if... | |
| Atma-Sphere Class D… Amazing The other part of the question....can they be made differential from INPUT to OUTPUT, as many conventional SSs are (ML, Pass,Moon, etc)? Is there a point? @fredag Things are a bit different when you’re employing switching technology, but FWIW... | |
| Atma-Sphere Class D… Amazing @fredag They have a balanced differential input (and RCA inputs are provided too). I run them balanced at home. | |
| Concerningly loud pops in vinyl playback Tubes in the ARC Ref 6 going bad. Maybe PSU tubes? But it really seems to be instigated by a volume level on the Ref 6 going above 40. @mulveling If this only happens when the volume is turned up then the turntable and phono section are off the... | |
| Atma-Sphere Class D… Amazing @fredag 100W with 8Ω, 200 with 4Ω. Current limit protection will kick in with lower impedance loads- as long as not to full power the amp will double its output power, but will reach its protection limit at about 250 Watts. | |
| Discuss The Viv Lab Rigid Arm Exactly, and that has been my point in this thread. To make real progress, we need to correlate measurements with what we hear. @cleeds Its been my experience that's what you do to sort out what's going on. That is what led me to increasing ri... | |
| Discuss The Viv Lab Rigid Arm I understand the mathematic fundamentals behind digital audio, for example (Fourier, Shannon/Nyquist), yet intuitively it still seems impossible to me. Like any technology digital had an uphill path to follow. For example jitter was a thing kno... | |
| Speakers for Atma Sphere M60 mk3 @fredag Your room is a bit on the larger side. If I were you I'd be wanting to see if an audition could be arranged. | |
| Speakers for Atma Sphere M60 mk3 @fredag How much power are you running right now? | |
| Speakers for Atma Sphere M60 mk3 @fredag For the M-60s I would use speakers that are at least 8 Ohms and 91 or higher efficiency. With any amplifier, tube or solid state, its beneficial for the speaker to be easier to driver rather than harder; this will always result in less di... |
