| SUT Interconnects Shielding adds capacitance. Cable geometry also affects capacitance. The 12AX7 tube, often used as the input voltage amplifier in tube MM stages has a high Miller capacitance that adds to cable capacitance. Transistors also add capacitance at the ... | |
| Detachable Head shell or Not? Aulait, my ears tell me there is a benefit associated with a direct wire connection. Is it night and day, and can I measure it? No. As to Richard Mak; I don’t know who he is. Difference I hear is for low output cartridges only. I don’t know why Mi... | |
| Phono input cap to preamp Also, C1 and C2 protect the coils of an MC cartridge from any DC offset at the transistor gate. I’d love to have that confirmed or refuted by any pro in the audience. Thx. | |
| My Elkit TU-8600S build review and questions DC voltage is almost always a constant in a circuit such as yours. So you should not think twice about that issue. Also carbon film are far more stable than CC types. One issue with CC types is drift of the resistance after repeated heating. CF wo... | |
| Detachable Head shell or Not? Mijo, are you thinking of the Z06 Corvette? Or is there really a plan for another ZR1? My friend and I have reserved a Z06, 50-50. But I want a Ferrari. Pre-owned is ok. | |
| Pioneer SL-570D TT Tonearm Suggestions On their upper tier turntables, Pioneer tonearms were excellent. I concur with others that your probably best off leaving well enough alone. | |
| Pioneer SL-570D TT Tonearm Suggestions Any good tonearm would do but the constraints on your choices have to do with the effective length and pivot to spindle distance and the specifics of how the OEM tonearm is mounted. None of these parameters are known to anyone but you. Not to say ... | |
| Phono input cap to preamp I looked up the schematic. C2 is the top half of a capacitative voltage divider network. C1 is the other half. Together these act on AC frequencies delivered to the input transistors. R1 is your phono load resistance. I have never seen this topolo... | |
| Phono input cap to preamp You got a plausible explanation for the capacitor from Atmasphere. I wouldn’t second guess him, but I do wonder why Hafler chose to use 10uF there and why he didn’t use a film cap, as well. Is this an MM stage or MC? If MC, what is the value of th... | |
| Phono input cap to preamp Can you reference a schematic? “C2” does not sound like the code for a series input capacitance. (I’d expect it to be C1.) Moreover if the phono load R is 47K ohms, 10uF is way overkill for maintaining a low bass response. You could get away with ... | |
| Detachable Head shell or Not? +2 to Frogman. The best connector is no connector at all. IME, the worst sounding connectors have been those that are massive and pretentious. If I must use a connector, I use low mass types, like KLE. | |
| Review of Quadratic MC-1 SUT With Comparisons to Other SUTs Is it “a SUT” or “an SUT”? | |
| Review of Quadratic MC-1 SUT With Comparisons to Other SUTs 3easy, isn’t it a bit premature to bemoan a lack of attention to Mulveling’s nice post? There is a lot of meat here to chew on, and we haven’t even heard from some of the pros, like Intact Audio and Atmasphere. I was only trying to point out, as M... | |
| Detachable Head shell or Not? For very low output cartridges, there is a good argument to be made for eliminating the headshell, because it adds up to two pairs of physical contacts in the signal path. So two of my tonearms one is a Reed and the other is a Triplanar have non-d... | |
| A new way of adjusting anti skate! My buddy in Burlington VT told me what you guys are expecting today. Wind chill of -25 degrees. I don’t own a coat for that. I am vacationing, if you can call it a vacation when you are already retired, at our house on the island of Vieques off th... |
