| Autoformer vs Speaker impedance Curve I would like to know how to measure that. 30% is hard to imagine. I test amplifiers all the time with ordinary power cords and have never seen this. This reminds me too much of Bruce Brission's white paper which was a total embarassment to his ... | |
| Solid State vs. Tubes - What if Transistors came first? Correct me if I'm wrong, but it's a SIT just a big power JFET? And I may be wrong, but I think IXIS makes some. I heard somebody talking about how to make a MOSFET produce triode-like curves at BA, but I can't remember who or when. I think it's... | |
| Which subwoofers have at least a 20k input impedance as required for ARC preamp Is replacing the preamp a possibility? There are other balanced tube preamps that have no problems driving loads like that. | |
| Solid State vs. Tubes - What if Transistors came first? I simply don't understand how one can conclude that dragging a diamond through a plastic trough doesn't cause wear. It defies logic, physics, and study. It does wear, but takes a *lot* longer than the studies done in the early 1960s concluded (... | |
| Solid State vs. Tubes - What if Transistors came first? 40-year-olds have no idea, save for a few cool ones, what tubes are. I know a heap of 20 year olds that know what tubes are. Anyone that plays a guitar does...The music industry dwarfs the high end industry. Thank God Apple and Bose are not respo... | |
| Balanced Signal Path Question The amp probably will see some advantage from using the balanced input. This is due to the fact that its input stage isn't perfect and will be lower distortion driven balanced. | |
| Solid State vs. Tubes - What if Transistors came first? I am all for tubes, but saying they are not an obsolete technology is a bit of over-optimistic stretch of imagination. Ask anyone younger than 40 about tubes. Chances are they will not have any idea what you are even talking about, much less ha... | |
| Best preamp output option for headphone amp hookup? Won't the Spectral drive headphones directly? We make tube preamps and *they* can do that... | |
| Is there actually a difference? Indeed. And you and I both know why. Well matched parts. When we talk about measurements here I'd like to think we're talking about more than the most basic facts on the side of the box. To really understand what a distortion figure means it ne... | |
| Solid State vs. Tubes - What if Transistors came first? You are, in fact, dragging a rock through a groove made of plastic with force equal to hundreds of psi. The rocks wear out. I'm pretty sure the plastic does too. This is a common strawman. There's no rock.And this is kinda why I don't take vinyl... | |
| Solid State vs. Tubes - What if Transistors came first? It is basically a preamp tube, very small directly heated wire cathode so that will have to be DC driven. The gain in circuit is 3.5 where a 12AX7 is typically 50. The max gains are 5 and 100 respectively.Output distorts badly at 1 volt out and... | |
| I need your help. I have an ARC Ref 3, ARC 110, Vandersteen 5As, but no turntable. One more thing. Tonearm cable. It is the most important cable in the chain, again don't save on it and don't rush with the choice.If you run balanced, then the cable will impose far less artifact. I agree its the most important cable in the syste... | |
| Advice and help understanding, choosing a Widebander / Single Full Range Driver speaker? Both the 8" and the 10" CubeAudio look like they might work really well in a line source array and perhaps wired in series/parallel or just in series.https://www.cubeaudio.eu/cube-audio-f10-neoI suspect though that a subwoofer is still going to be... | |
| Autoformer vs Speaker impedance Curve The bass is markedly more pronounced from my tube amp (60 Watt push pull, KT88, “some” local negative feedback) than my SS CA-2300. It’s also seems “looser” or less defined. Nonetheless, it seems reasonable to my novice brain that if an increas... | |
| Is there actually a difference? The ability to drive difficult loads. How robust is the power supply? etc. You can make an amp that sounds acceptable at low levels driving easy loads. But, when you really need power (not volume), it is like trying to get large flows of wa... |
