| Tube Amp for Martin Logan Speakers Unsound, I don't see the comments you found doing anything but supporting my position, and also this:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpThe bit about Jim Theil using drivers in parallel to get more current out of... | |
| TriPlanar Tips Syntax, that strength of the Phantom is one shared by the Triplanar. It really sounds to me that you had either incorrect setup or simply a poor match between arm and cartridge. You are correct that all cartridges put energy into the arm- this is ... | |
| Ssssh, is your tube preamp really that quiet? Phd, all active circuitry makes noise. Transformers are passive devices and don't make noise, but there is a price paid for their use as well. IOW there is no free lunch. IOW there is no curse :)I see the words 'dead silent' used a lot. I know tha... | |
| Tube Amp for Martin Logan Speakers Bruce, I am a moderator on another site that is unrelated to audio. In that regard they put me through some training so that I could spot posts that went beyond the pale. I don't see Unsound doing that- he attacks the argument, not the person (whi... | |
| Tube Amp for Martin Logan Speakers on this very forum speaker builders have suggested that with a lower impedance they can more easily achieve deeper bass response (extended frequency response), a more linear impedance (improve linearity of frequency response)and as you've said a l... | |
| Tube Amp for Martin Logan Speakers Tube amplifier power has always been more expensive (the tubes themselves cost more, the filament circuit to light them up costs something, so does the output transformer). It was the reduced cost of transistors that got the industry going in that... | |
| Ssssh, is your tube preamp really that quiet? Phd, your hiss is coming from your line section, not the phono.Jwpstayman, your preamp makes hiss but not at the levels you play with the cartridge you use. All preamps make hiss- its a fact of life. | |
| Tube Amp for Martin Logan Speakers George, you took the quote out of context- sounds like you didn't read the article to me.Unsound, I have a number of friends in the industry that make transistor amps. When Steve's letter turned up, I asked them about this and their response (para... | |
| Tube Amp for Martin Logan Speakers I take it Unsound, that you are an advocate of increasing distortion :) Because by disagreeing with me, that is exactly what you are doing. Let's try that on for just a moment. Usually in high end audio we are interested in getting rid of colorati... | |
| Ssssh, is your tube preamp really that quiet? Manley Steelhead into Manley NeoClassic 250 monoblocks: dead quietThis is an example of a phono section that employs a semiconductor at its input, IOW, it is not all-tube.Ralph, is it possible to make a tubed phono section without a SUT that is no... | |
| Ssssh, is your tube preamp really that quiet? Are you saying that without an SUT, all tube phono preamps will solicit some tube hiss when the gain is turned up and no music is playing?Actually, all phono sections make noise. Tube units tend to make more, thus SUTs are more commonly used with ... | |
| TriPlanar Tips The Triplanar is recommended for cartridges which do not reflect ANY energy into the Arm. The Arm looks solid, but it isn't.All cartridges can put energy into the arm if they are not set up right. What is supposed to happen instead is that the sty... | |
| Ssssh, is your tube preamp really that quiet? No all-tube phono section is perfectly quiet. But a lot has to do with what cartridges it can work with and whether it has an SUT or not. If we use an SUT with our preamp the noise is not an issue with any cartridge. If no SUT then when you turn u... | |
| Tube amp power watts equivalent to Solid State? Atmasphere, am I to understand that you're suggesting that as long as an amp avoids actual clipping that it will sound more powerful the more it distorts?Yes, to a certain degree. It will sound **louder** more specifically. This distortion thing c... | |
| Tube amp power watts equivalent to Solid State? Al, Ralph......we are all waiting. Try to be as accurate as Unsound was please. ;^)If we actually graphed the amplifier's distortion response when subjected to a standardized non-repetitive waveform, we could probably put numbers to that. Until th... |
