| SUT - electrical theory and practical experience @alexberger I use 20 Ohm input (26dB, 1:20). The phonostage has overload points - (1% THD+N) for the 834P were 69.2mV at 1kHz, 260mV at 20kHz, and 7.85mV you seem to have a frequency number missing from the above since you have three voltages... | |
| SUT - electrical theory and practical experience @o_holter I tested a SUT with the Io and did not like it - sounded good at first but then I noted that it subtracted from the purity, the sound became more hi-fi, for lack of a better word. But that was with a mid level SUT years ago and things... | |
| SUT - electrical theory and practical experience @rauliruegas Btw, @intactaudio : you capacitance parameter of 80pf coukld be not real to make SUT measurements as the 300k load. as stated in the text you pulled the above numbers from, those are the actual values of the referenced phono sta... | |
| SUT - electrical theory and practical experience Whether a cartridge is a 'voltage' or 'current' generator simply comes down to the load you present it with. Make the load an open circuit (volt meter) and it will deliver max voltage and essentially 0 current. Make the load a short circuit (amm... | |
| SUT - electrical theory and practical experience @rauliruegas I should be sure you have that RIAA deviation already measured and maybe you can share with us and your customers. I'm hesitant to give you a measurement which you will certainly turn into a cudgel to use on me in the future but ... | |
| SUT - electrical theory and practical experience @rauliruegas Blindly parroting frequency numbers without clear designation of the related decibel level is an effort in futility. In looking at the 3-200kHz number of the Technics you reference (SH-305MC) there is no designation of the attenuat... | |
| SUT - electrical theory and practical experience @rauliruegas Btw, could be interesting that your friends can ask to EMIA its measured FR due that even that exist audiophiles that just do not care about that kind of measure is really of critical importance and the manufacturer just " dead sil... | |
| Field coil dava cartridge @rauliruegas you are rigth, the 12" against a 10" EL tonearm in reality makes almost insignificant " improve " in tracking error. Using Löfgren A alignment IEC: for someone who insists on 0.1dB riaa accuracy for hi-fi, you sure seem to ha... | |
| What is the “World’s Best Cartridge”? @frogman I know and am confident in what I hear. well put! I often find that those who rely heavily on the objective are incapable / uncomfortable forming a consistent subjective opinion. I am by no means suggesting that the objective has n... | |
| What is the “World’s Best Cartridge”? @mijostyn In order to fool the human ear you only need a 0.3 dB difference in volume. do you have a reference on this? I know the origin of the decibel scale is based on 1dB being the smallest difference in level detectable by the average pe... | |
| What is the “World’s Best Cartridge”? @dover I use the word symmetrical deliberately rather than the word balanced. Ahhh... point taken. If the SUT were truly symmetrical as you state then one could reverse the polarity of the primary and net the exact same frequency response at... | |
| What is the “World’s Best Cartridge”? @dogberry I expect we all know that volume influences how we perceive sound, and are aware of the warning that a constant desire to turn the volume up indicates there is something inadequate in the sound chain. That one is new to me and in fa... | |
| What is the “World’s Best Cartridge”? @mikelavigne ..but most of the best phono preamps are not true balanced designs, which is another issue. This is the key issue. As ralph points out just using an XLR means nothing and in order to take advantage of a balanced interface one mu... | |
| Does Everyone Use 2 Phono Cables with SUT There is actually one substantial difference between the cable that feeds the input of a SUT and the one that comes from the output of a SUT. The difference is the impedance level at which they operate which dictates the situational needs. Lets ... | |
| Added an SUT...not sure I understood this @dover This splinter of the OP's tree is in reference to the load a cartridge sees and in particular any variance from the cartridge manufacturers suggestions. Lewm was comparing active mc amplification vs SUT's. No.... Lew was wonderin... |
