| I have Maggie MG 1.6's - need amp advice Eldartford, this commentMost solid state amps are power-limited by current. Tube amps, whose power supplies run at several hundred volts, may hit an output voltage ceiling, resulting in a flat top on a sinusoidal signal called (for obvious reasons... | |
| Truely Balanced Pre Amps The advantage is lower noise and lower distortion, to the point that less gain stages can be employed. There is less than double the parts so the cost ought to be less than double too. And yes, there is a fully differential way to do this. | |
| Truely Balanced Pre Amps A 'fully balanced' preamp will not have the signal appear anywhere in the circuit in single-ended mode, except at an input. So all the switching, the volume control, EQ is all in the balanced domain. So how many drop out when this rule is applied? | |
| What are the trade offs? PUSH PULL vs. pure SET Hi Groovey, thanks for the link. In general Eddy is on the money. He does leave out some details that *I* think are important- namely OTL amplifiers. Take away the output transformer and you remove most of the arguments for SE. So it then becomes ... | |
| What are the trade offs? PUSH PULL vs. pure SET Yes, the triode operation of an amplifier that has tetrode or pentodes is compromised. Such tubes in triode mode are not as linear as real triodes.In triode mode, a push-pull amp still differs from a triode amplifier that is single-ended. Push-pul... | |
| I have Maggie MG 1.6's - need amp advice Dear Atmasphere,Could you write a word or two about what you mean by "The trick with any tube amp is an effective 3-4 ohm capability...". Thanks.Let's put it this way- tube amps in general do not perform as well on 4 ohms as they do on 8 or 16. Ou... | |
| Einstein OTL amps experience Hi Doc, what kind of MA-1 Mk.IIIs do you have? | |
| I have Maggie MG 1.6's - need amp advice Maggies are easy to drive up to the 'knee' of their magnet system which is not push-pull (MG 20.1s are an exception and are easy to drive at any volume). Getting additional volume above the knee requires a lot of power as the speaker dynamically c... | |
| tonearm match ZYX Universe Moerch and Triplanar If you can afford the Triplanar it will work well even on a cheap turntable and better than a cheaper arm. I run the ZYX Universe on the Triplanar and it is unstoppable. Records that I thought were noisy are quiet and records that I thought were d... | |
| Amplifiers and Horn Loudspeakers A lot has to do with the output impedance of the driving amp too. A lot of horns are highly reactive and this plays havoc with feedback networks in transistor amps... | |
| Amplifiers and Horn Loudspeakers In my band I run transistors with horns all the time. That is not what I would do at home though. It seems that horns are far more likely to own up to the bad side of their reputation with transistors (honky, shrill) and that transistors are large... | |
| Amplifiers and Horn Loudspeakers Why do you think it is that amps with zero or very little negative feedback sound so much better than those with lots? And that on amps with adjustable feedback changing it is indeed very AUDIBLE?Horns for the post part are expecting constant powe... | |
| Opportunity to buy the best Preamp... but which? There's been no discussion about SE/balanced... in preamps this can be a big deal on account of the interconnect cables.So- if funds are unlimited for a preamp, what amps do you have? Will they accept either input? | |
| Replacing metal oxide with Vishay/Dale metal film The Vishay metal films will be an improvement. To really get what they are about, you will have to replace all the resistors in the signal path and all those that are in the cathode and bias circuits as well.Coupling caps are another area you can ... | |
| What do you look for in damping factor? Ralph, I am slightly confused. Are you trying to say that:A. The perceivable synergy of the Rowland 312 and the Mahlers exists in spite of the amps high damping factor?B. The 312's damping factor is immaterial to its synergy with speakers in gener... |
