| impedance match of preamp and main amp. Changing the coupling caps in the preamp may not be the best move. The bigger the coupling cap, the more coloration it can impose at frequencies well away from the cutoff frequency. For this reason coupling caps are often made as small as possible... | |
| Why do designers/manufacturers...? Jea48 is correct, power cords are not just power delivery. The measurable differences don't seem to be profound, but they can affect power amplifiers in particular in a number of ways.First is the voltage drop across the cable. When I saw 40 watts... | |
| Harry Weisfeld Was Right All Along According to Tri Mai of Triplanar there is in fact no standard for the amount of anti-spate to be applied.In practice I have found that very little is needed on the Triplanar. I don't use the weights- just a few tiny rubber o-rings on the antiskat... | |
| Soundlab speakers with sub woofers? On most tube amplifiers its a good idea to try the Sound Lab on the various taps of the output transformer to see which works best.Some transformers can ring if not properly loaded- so if you are on the 8 ohm tap and the amp is playing into a 30 o... | |
| Quality system, make poor recordings sound better? I use bad recordings as a yeardstick to tell me how I am doing. IME, a system can 'editorialize' and can often react poorly to poor recordings, and also recordings with lots of energy.An example from the old days was Village Music of Bulgaria on N... | |
| Why do designers/manufacturers...? Tweaks huh? A long time ago we started using toroidal power transformers, and we noticed some odd things. One was that if the amps were too close together, they sounded different. Another was that the bolts supplied by the transformer manufacturer... | |
| The HH Scott 350 A MultiplexCircuitry Yes- it needs the multiplex section to be aligned. The shop will need a stereo multiplex generator to do the service. | |
| Soundlab speakers with sub woofers? Hi Bob, You got it almost completely right in your last paragraph- right up to the last sentence... so, you said The power dissipated by the speaker will fluctuate throughout the audio band inversely proportional to the impedance.Which is correct.... | |
| Most enduring audio purchase Triplanar! Its so nice to know that no matter what I throw at the system, the tone arm will track it perfectly and reliably year in and year out. | |
| Solid state "single ended" pure class A preamp Yes, I've never heard of a preamp that was not class A. | |
| Grounding Normally the ground on the AC outlet is fine.If your system needs more than that, take it as an indication that the ground circuits in one or more components in the system are not set up ideally for best results. | |
| Soundlab speakers with sub woofers? I thought I was pretty clear with my point, but maybe not. Here it is, referring to the math I posted earlier:1) many solid state amps will not get flat frequency response- if so they will be bass shy and too bright.Some people with transistor amp... | |
| Solid state "single ended" pure class A preamp SET means 'single ended triode' FWIW.If you really want some of the attributes you had before, I would steer well clear of a solid state preamp. You want a tube preamp, and probably a single ended one at that. | |
| Stand out phono stages All preamps are class A FWIW. | |
| Soundlab speakers with sub woofers? In my feeble mind I imagine a relatively fixed voltage across the speaker terminals. As the impedance changes with frequency so will the current drawn from the amp and so will the power supplied by the amp. When the impedance rises in the bass, th... |
