| SUT - electrical theory and practical experience The point I was trying to make when I pointed out that transimpedance phono stages generally are just voltage driven stages with a current to voltage converter added on to the front end is that they are subject to foibles just like voltage input p... | |
| System that sounds so real it is easy to mistaken it is not live I fully agree that TL bass is not suitable for your particular goal unless you have room for truly massive cabinetry. I’m getting what bass I want with what I have. You ignore the fact that I used HDF, not MDF, and that the cabinets are further d... | |
| Checking Anti-Skate? Eldartford, skating force increases with increasing VTF, because skating is caused by friction between stylus and groove. so the desired amount of antiskate also should increase accordingly. Increasing VTF is certainly not the cure for the skating... | |
| SUT - electrical theory and practical experience Also, in a voltage driven conventional stage, the input load R can be thought of as the simplest form of passive current to voltage converter. | |
| SUT - electrical theory and practical experience To the notion that cartridges are “natural” current generators I would say that the general statement can only be applied to LOMC cartridges with very low internal R in relation to V output. I would also note that in a “trans impedance” stage , th... | |
| High Performance Low Mass Tone Arm Suggestions Needed Alternative Dynavectors that work on your SOTA would include DV501, 507, and 507 mkII. Or any tonearm with effective mass less than 12 or so g, based on my experience with the Triplanar. Going from the theoretical optimum of 5g to 10g would only d... | |
| Grado Epoch 3 Doggie, it is very odd that you prefer 100 ohms load on your statement 3. According to two sources it has an internal R of 74 ohms and an inductance of 8 mH, about 100X to 1000X higher than a typical LOMC. Moreover Grado recommends 10K to 47K. At ... | |
| High Performance Low Mass Tone Arm Suggestions Needed “A substantial counterweight “ might wreck your chances for low effective mass unless you mount it close as possible to the pivot. I’ve had good luck with my Dynavector DV505 and my Triplanar and the MC2000. But if you’re religious about matching ... | |
| System that sounds so real it is easy to mistaken it is not live The TL is not a “sub”woofer. Nor did I want it to be. I’ve built two pair, so I’m well aware of the complexity, but I beg to differ on the woofer shaking the cabinet. Not much of that happens because the driver is very lightly loaded. Anyway, one ... | |
| Linn Linto Brilliant power supply interchangeable with Linn Karik Brilliant power supply ? I hope for your sake that neither is a 13V supply. | |
| System that sounds so real it is easy to mistaken it is not live Mijo, In a distant way, there is a relationship between a transmission line and a dipole design, or whatever you call the type where two woofers are working in or out of phase, back to front or front to front. The transmission line is akin to an o... | |
| Linn Linto Brilliant power supply interchangeable with Linn Karik Brilliant power supply ? It's all about matching voltage and current, and I doubt that a phono stage and a CD transport would have identical requirements, but it's possible. Also, why not ask Linn? In fact, definitely ask Linn before taking any advice here. | |
| VTL MB-450 or Manley studio 440 input voltage modification Bill, that's a viable idea, but these behemoths pull a lot of current, and one would always wonder whether the step down was doing a good job of supplying same. So maybe if you used a step down with a 2X or higher excess of peak current draw it w... | |
| SUT - electrical theory and practical experience Raul, to state the bandwidth of any transformer, particularly an audio SUT, without specifying the upper and lower limits of the given bandwidth in db, the impedances on the primary and secondary windings, and the other reactive components of the ... | |
| System that sounds so real it is easy to mistaken it is not live I think Mr Volti was a furniture maker before he went into the loudspeaker business. His cabinet work is certainly first rate. |
