Has anyone had any issues with the very high input capacitance (1000pF) of the Onkyo A-9010 phono stage ? I'm thinking about getting one of these amps, based on all the positive reviews, but it needs to work with vinyl.
Most MM cartridges require a load capacitance in the range 100 to 200pF, and usually 100pF of that is due to the phono cable. A typical MM cartridge has an impedance of around 600 ohms + 400mH, and a load of 1000pF would give a massive peak in the response at around 5kHz, so is totally unsuitable.
I've contacted Onkyo twice about this but got no response.
