| grado hum Most tone arms with a single-ended output will also have a ground wire for the tone arm ground. In the case of a high output cartridge like the Grado, sometimes the cartridge can pick up hum from the motor if the motor is not also grounded to the ... | |
| Tube vs Tran Plus not all tube amps have output transformers :) | |
| Sound Anchor Component Stand We've used one for years. One of the nice things about the Sound Anchor is it can be custom built. In our case, it was custom built to accommodate our preamp and turntable, each of which has its own anti-vibration platform.The stand sits on a set ... | |
| grado hum We had a Rega with a Grado that hummed; I found that neither the platter bearing nor the motor was grounded! Adding a wire was all that was needed- presto! no hum. The wire tied the ground of the motor to the platter bearing and the tone arm ground. | |
| Experts: Why is preamp important? Tomcy6, for termination of a balanced line 600 ohms is the standard. By preamp standards, this is a very low impedance and many preamps can't drive that without a loss of bass, loss of signal level or both. Even though the termination is often not... | |
| Speaker Effeciency and Bass Production Cyclonicman, there are OTLs that can make 500 watts, FWIW. | |
| Tube vs Tran Dave, I respectfully disagree. The idea of damping factor is mostly mythology. If you hear a differece between an amp with a 'damping factor' of 1000 and one with 50, its likely due to other things than 'damping factor'. More likely the difference... | |
| Experts: Why is preamp important? Pinkus, in fact our preamps are designed to support the balanced line standard- in effect dramatically reducing the effect of the interconnect cable to the point that it is no longer important. This is not to say that you can't hear differences, b... | |
| Experts: Why is preamp important? Don_s, If a preamp has a low output impedance, many of the differences you are accustomed to hearing in interconnect cables go away.In fact the balanced line system used for decades in the recording studio and broadcast was conceived to eliminate ... | |
| Science & Sound, Tube or Solid State Phono? What we found with the MkIII was that proper constant current sources with differential amplification is the way to get tubes to be really quiet. The difference is quite noticeable.It also helps to have quiet tubes! Most NOS tubes these days are f... | |
| Better than a CAT? The Merlins are a very easy load and they show off a tube amplifier very well! | |
| Power amps for Quad electrostatics 2905 Newer Quads have a lower impedance than the older ones, as Quad contiues down the same path that Martin-Logan took, trying to get transistors to work with ESLs. But the nature of ESLs is that tubes will drive them without high end empahsis and bet... | |
| Why does it sound better at lower volumes? If the problem is volume related, either your room is getting over-driven at higher volumes or physical vibration is upsetting your front-end. The latter can be solved by proper equipment stands and anti-vibration platforms- probably for the signa... | |
| Experts: Why is preamp important? preamp functions:1) provide volume control2) input switching3) provide any needed gain or attenuation4) and least understood- control the interconnect cable between amp and preamp to minimize the effect of the cable. Most sources cannot do this BTW. | |
| Why do amps sound different? Tvad, it can be (usually not clipping though), but there are other things that can do that that I would think would be more likely. Resonance excited by volume in the system is where I usually start when looking to kill sibilance. Cartridge setup,... |
