| Current amp vs Voltage amp Sorry I got to this late. It seems there are some things that need clarifying. If I am not beating a dead horse too much...Bifwynne, by adding negative feedback to an amplifier you do indeed move the amp towards the Voltage Paradigm. This is becau... | |
| Using autotransformers Hard to say. Monster's website seems pretty bad, and does not say how much current the device can handle. You will have to call a dealer or such and find out. | |
| Using autotransformers Ferro-resonant transformers don't work so well for audio. They make a lot of physical noise and electronic noise too. | |
| Tannoy Westminster amp matching question. Borg7x9, it should not be that big a deal to change the input impedance of the amp. It may be that it has an input transformer- this is not all that strange in the world of SETs. It might be that the transformer has to be replaced. That is not all... | |
| Is soundstage just a distortion? I suspect the reason that the Decca does so well in Csontos' system has something to do with the effective arm mass, the speed stability of the table, and the short cantilever used on the Decca.If the 'table has a slight (inaudible) speed variatio... | |
| Tannoy Westminster amp matching question. Driving a 600 ohm load is an unusual task for most home audio preamps. We make the only tube preamps that can do it. There are a few solid state units too, but as you found out just because its a transistor unit does not mean it can drive this kin... | |
| Less than top line reel-to-reel worth it? Rockboy, Tape shedding is a function of too much moisture that the tape has absorbed.We recently did a reissue of an early 70s LP; the master tapes were stored in an attic and because it was dry and often hot, the tapes were in immaculate conditio... | |
| Bass leaves after amp warms up? No. But if you have problems again when you install it, you will know what to do. | |
| Tubes/SS Power Amps? It was a joke. If you run a real high voltage on tubes they can emit X-rays. | |
| Tubes/SS Power Amps? Generally speaking class D amplifier modules are less expensive. I have a 100 watt/channel module that cost $25 each in low quantities. It is the size of a pack of cigarettes, including heatsink, input/output connections and power supply connectio... | |
| Why should you need a power supply for preamp? The outboard power supply allows one to keep noisy transformers, rectifiers and the like outside and away from the preamp unit, which might have high gain circuits in it that might be quite sensitive to such noise.An outboard supply is generally s... | |
| Is soundstage just a distortion? Soundstage is the result of two things- good high frequency response and good phase reproduction (low phase shift). If both are correctly reproduced side information that appears to be beyond the spread of the speakers is normal. The Soundstage co... | |
| Bass leaves after amp warms up? Fishing, I'm pretty sure I suggesting removing the power conditioner on page one.The problem with most power conditioners, whether passive or active, is they force you to use a common power cord. If you get a voltage drop over that cord, it will r... | |
| Can I tweak L-R balance by differntial biasing? Swampwalker, yes, whoever wrote that is mistaken. Reducing the bias may actually get you a couple more watts, rather than less, as the B+ voltage may rise with the reduced quiescent current. But you would also have more distortion...Csontos, It so... | |
| Less than top line reel-to-reel worth it? I've been into Ampex pro audio machines for about 40 years now. I think I have had the same electronics (351) for about 35 years. They have been rebuilt three times.The old Ampex stuff is pretty bullet proof, not as nice looking or as easy to oper... |
