| Half speed master OK- any cutter head you can think of has a resonance that occurs at a high frequency. My Westerex 3D (which is what RCA used for many of their Living Stereo releases) for example. No amount of messing with the suspension seems to affect it. To dea... | |
| Dynaco ST-70 The ST-70 can be driven easily by any preamp made. The real issue is that the speakers are low efficiency- 88db, so the issue is whether or not 35 watts will be enough in your room with your listening habits. | |
| Tape decks - still of any value? There is a Nakamichi user's group on the web.http://www.naks.com/ | |
| SME V or Graham 2.2 on Michell Gyro SE Either arm will work fine on the table. Its an entirely different matter as to what cartridges work with those arms, and that issue is far more important. | |
| Half speed master Half-speed mastering is done to move the resonant frequency of the cutterhead up one octave. This makes it a lot easier to deal with. Decca developed this technique in the 1950s; many Londons and Deccas are 1/2 speed mastered. | |
| Is it possible? A good solution? Audio is one of those things that really responds well to keeping things simple. Adding additional building blocks in the signal path is rarely a good thing. If you really want to hear analog done right, you keep any additional processing, especia... | |
| SET Preamps OK 'improved upon': *lower noise, *blacker backgrounds, *far greater immunity to the length or quality of the interconnect cables, *lower distortion/less need for negative feedback (since distortion components would be canceled with each stage of ... | |
| Power output of tube amps compared to solid states Myles, the mbl has an impedance peak of about 8-9 ohms in the midrange driver. The designer is expecting the amp to reduce power by 3 db through this range. An amplifier with feedback will do it, one without will not. A good number of tube amps te... | |
| really? .89c ground lifters? The way it is done in pro-audio situations is to make sure the heart of the system (in a pro audio system: the mixer, in a home system: the preamp) is the only thing that is grounded. Otherwise there is a good likelihood of a ground loop between t... | |
| SET Preamps If you want my opinion I really feel that if you do fully differential in the preamp, there is a huge benefit there also, IOW even though there are many very musical single-ended tube preamps, they *can* be improved upon. | |
| Woofers Gone Wild Actusreus, what kind of speakers do you have? One area where there is not much you can do is if you have smaller woofers in a smaller cabinet. Once you get out-of-band there is nothing keeping the woofers from flopping around. In a case like this ... | |
| Power output of tube amps compared to solid states I think they do. It would be really tricky to build a zero-feedback transistor preamp. With tubes you can do three stages of gain between the LOMC phono input and the line out, I doubt that the same can be said of transistors, at least, I've not s... | |
| Power output of tube amps compared to solid states In the last 20 years the use of SETs has really increased a lot. It has resulted in a lot of speakers that were simply not available 20 years ago. So these days its ten times easier to find a speaker that works with 'current source' amplifiers tha... | |
| Woofers Gone Wild Actusreus, I guess I would really challenge whether or not that cartridge and arm combo is really correct. I'm a big fan of Occam's Razor, so I'm always looking for the simplest explanation. So when I hear that, the simplest explanation to me is t... | |
| Power output of tube amps compared to solid states Unsound, I think the 'harm' comes in when the speaker requires that the amp use a lot of feedback to work right with the speaker. Since our ears use the 5th, 7th and 9th harmonics as a means to perceive sound pressure, and since negative feedback ... |
