| Help Diagnose Tube Preamp Problem Sometimes AC power switches can develop issues that will cause crackling. This is caused by bad contacts in the switch. Tapping on the switch can sometimes excite the behavior.If you get a pinging sound by tapping on the switch, it is because vibr... | |
| Why Don't We See More High Current Electronics? Yes- audio equipment does not care what kind of music you play on it. An amp with a low output impedance does not have a frequency response that varies with a speaker's impedance.That depends on how the speaker is designed. Take a look at http://w... | |
| Why Don't We See More High Current Electronics? Peterayer, we agree on that- all the system can do is reproduce the recording as accurately as possible. | |
| Anyone tried Soundlab Dynastats out of phase? I remember in the old days (early 90s) we could blister the paint off the walls with a set of Dynastats and our M-60 amplifiers, which played a lot of authority in the bass at the same time.Later versions of the speaker had the new toroidal transf... | |
| loading resistor question Romaxim, in a nutshell:The issue is that with LOMC, the inductance of the cartridge and the capacitance of the cable and input form a tank circuit resonant at ultrasonic or RF frequencies. The activity of the cartridge on the LP is enough to excit... | |
| FURMAN, PS AUDIO, ISOTEK?? With any power conditioner that has magnetics in it (the Furman and the PS Audio both do) should not be run past 50% of their capacity, else they will degrade things rather than help. The reason is distortion of the AC power, which usually becomes... | |
| Why Don't We See More High Current Electronics? Here's one more for you:http://www.atma-sphere.com/papers/paradigm_paper2.htmlWhy not ask what the relationship is between doubling power and how your ear/brain system hears? The short answer is that you get flatter frequency response, but only wi... | |
| Calculating total capacitance With higher output moving magnets it is possible to use a capacitor to load them, but IME you get a more open sound if you use a resistance instead, since the cap will have the effect of rolling off the highs.The issue here is that the cartridge r... | |
| Any tube rec's on Vandersteen 5's The speaker is 8 ohms and friendly to tubes. | |
| Who makes the best passive volume control? A little OT but how can you tell if an active is controlling the cable in the way you describe? Any good way of measuring this? In something like Stereophile's equipment measurement, any particular that will give agood idea of cable control, degre... | |
| Explain Amp classes & how effects sound? Most transistor amplifiers do operate pretty close to class B; at low power levels most of the power comes from the driver transistors rather than the outputs. But in order to keep the amplifier from making significant distortion (notch and crosso... | |
| Lightspeed Attenuator - Best Preamp Ever? George, I appreciate that you want to keep it simple but you already have that product. If something was created pretty much like you and I have described, it would be better, but it would not be as simple. But that's OK- there would still be a ma... | |
| Who makes the best passive volume control? The Lightspeed is the best we have tried.However all passives have certain limitations, and if you exceed those limitations, they will color the sound quite noticeably, and rob you of dynamic impact, regardless of how good they are.The primary lim... | |
| Quads 57 - We've had a lot of customers with Quads over the years. In the last 35 years, one thing has been apparent in that time: Quad owners are often very loyal to the product. Given the span of time involved, the 57 and 63 have seemed to enjoy a loyalty ... | |
| Lightspeed Attenuator - Best Preamp Ever? I can think of one: If a remote were built into the product, the actual volume control system (as a module) could plug directly into the input of the amplifier (with separate left and right hand channels) rather than being in a box that needs an i... |
