| Hi efficient speaker, bass problems Tmsorosk, it may be a language issue, but the appearance is that your post is in contradiction to the title of the thread. In addition, your post mentions low efficient speakers and then in the same sentence less sensitive unitsso its hard to know... | |
| Lightspeed Attenuator - Best Preamp Ever? Clio09, I had the opportunity to compare the Lightspeed against one of our own preamps and I have to say it was the most neutral passive I have heard.Like any passive I have heard, it had less bass impact than the preamp, which as I have already m... | |
| DC issues using a Krell KSA 150 w/ tubed preamp? Unsound, even if there was a tube failure, DC would not be the result. DC would be the result of a coupling capacitor failure, something highly unlikely in a tube preamp, as said cap would be a film type, which are very stable parts that last deca... | |
| DC issues using a Krell KSA 150 w/ tubed preamp? There is no such thing as 'tube DC'. No preamp, tube or solid state, will make DC at its output if it is working right. IOW, the idea that tube preamps have DC at their output is a myth. | |
| Lightspeed Attenuator - Best Preamp Ever? Digital volume controls have always been an irritant. As far as I am concerned, they are a failed concept. Given the brilliance of the Lightspeed system, it would seem a natural in a DAC or CDP. | |
| Lightspeed Attenuator - Best Preamp Ever? Clio09 a low output impedance will mean that the preamp can drive a load of less than 1000 ohms without loss of bandwidth, voltage or increase in distortion. You don't need negative feedback to do that. In the old days, tube circuits did that with... | |
| How to accomodate a balanced only phono stage ? Mordante, your best option in this case is to replace the junction box with one for XLR cables, and run everything balanced. The advantage of doing this is that the cables will have less overall effect on the sound- they will be more neutral. | |
| Lightspeed Attenuator - Best Preamp Ever? Pubul57, there are 4 functions of a line stage:1) add any needed gain- not all sources are able to drive an amplifier to full output.2) provide for input and volume control- this function is shared by most passive and TVC systems.3) buffer the vol... | |
| Lightspeed Attenuator - Best Preamp Ever? George has pointed to exactly what the problem is. In order to produce proper bass, there can be no phase shift above 20Hz. Fletcher-Monson has nothing to do with it. If it were F/M at the heart of this, the same loss of bass phenomena would be he... | |
| Lightspeed Attenuator - Best Preamp Ever? Yes, Al, George seems to have missed my point entirely. If you think about what happens when you install a resistance after a capacitor, then you have a start at what is happening with any passive system. The cap has a variable impedance vs freque... | |
| Tubes to Watts Ratio Bojack, just to be clear, the proper term is 'self bias'. Self bias gets the bias for the power tube by dropping a voltage across the cathode resistor of the power tube. An autobias circuit does not do that. All autobias circuits generally fall in... | |
| Lightspeed Attenuator - Best Preamp Ever? Yup. If you are running a passive volume control, it does not matter how neutral the control is (and the Lightspeed is one of the more neutral ones we have seen), the problem is the interaction of the cables, the source impedance and the input imp... | |
| how close in sound can a tube and ss amp sound ? So far the closest I have heard a transistor amp to sound like a tube amp is one that sounded so neutral that it would be best to say it sounded like music the way a good tube amp sounds like music, without much in the way of artifact.That amp is ... | |
| how close in sound can a tube and ss amp sound ? Maybe you should write one of your white papers to make it easier for the those of us living in the forest to understand. How about:"The inaudible effects of clipping when comparing 2 amplifiers that arent clipping but would if you pushed them to... | |
| how close in sound can a tube and ss amp sound ? Audiofeil, my point is that during that comparison, no-one is thinking that they are comparing amps that are clipping. They don't know that that is what is happening. If you have a speaker that is 89 db and a 35 watt amp, depending on room size an... |
