| 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... | |
| Solid State vs. Tubes - What if Transistors came first? Sorry man, but vinyl is the absolute most compressed and limited medium on the market.I run an LP mastering operation if that’s any help here. You are incorrect about LPs on a number of counts. Specifically with LPs vs CDs, **usually** the CD is m... | |
| Mounting a Triplanar or similar on an SP10 We had a 12" Triplanar on the SP10 MkIII at RMAF about two years ago. We might have something like that this year too. | |
| I need your help. I have an ARC Ref 3, ARC 110, Vandersteen 5As, but no turntable. @inna Ralph always says direct drive Technics, that's his preference, which is fine.We've been making a belt drive machine for about 20 years. It is very neutral but the Technics is less expensive and I think its a better machine and even include... | |
| MAC Autoformers? What is bifurcation in feedback?Put very simply, bifurcation is the process where feedback can cause a 2nd to become a 4th and so on. Norman Crowhurst wrote about this and I think later also Baxandall. If you look into Chaos Theory you will see qu... | |
| Autoformer vs Speaker impedance Curve Guess that explains the bloated bass when I run 802D3s on my tube amp. No- it doesn't. If the amp is able to act as a voltage source, then it can make enough energy to be flat on the 4 ohm load of your woofer array. Since you say the bass is bloat... | |
| Is there actually a difference? Looking at basic specs like damping factor and THD+N doesn't tell you much of anything about an amp. I'd rather have an amp with .01% THD+N with a beautiful negative 2nd harmonic than one that's .001% and all high odd order distortion. The prob... | |
| Solid State vs. Tubes - What if Transistors came first? If transistors had come first, the world of rock and roll would be vastly different!! You can't overdrive solid state amps very well at all; rock depends on that overdrive clipping sound that is still only available from tubes. As to hifi, the dis... | |
| Have Passive Preamps Finally Come of Age? ^^ You are correct about that. Redbook has most DACs too much voltage for most amps made. | |
| MAC Autoformers? The Class A3 amp sounded good too. The pot is not dual but single with a switch attached, thus the click into the high damping condition which cuts out all the Zmatic circuitry resistor losses. It is indeed a combination of voltage and current ... |
