    Dynavector 10x5 loading question

    Post by xlr8 on Tue Nov 19, 2013 9:45 am

    I wondered if any of you guys use this cartridge with any of the VTA phono preamps and if so, what resistor values have you settled on? I have a PH-15 which I purchased as a kit and built last year. I set it up for MC with the provided resistors and although it sounds great the way it is, I thought I'd try and get closer to what the manufacturer says is an "optimum" (1k) load and see what happens. Also, after doing some reading, I'm wondering if the 2.5mv output of the 10x5 runs any risk of overloading the preamp in MC mode? I have already ordered an array of Takman resistors to try, just looking for a good place to start. Thanks!

    I would PM to TMadden; you can find him on this board somewhere pretty easily.

    I've used the Dynavector 10x5 high output for years with the Audio Research PH 2 set for standard moving magnet loading (47K ohms).  The spec sheet for the cartridge states the load ">1K ohms (greater than)".   The original selling point of the 10x5 HO was plug and play in a regular MM phono circuit.   The 2.5mV output may overload a MC input though.  But nothing wrong with experimentation and what works best for your setup.

    no risk of input overload using a PH14, 15 , 16 with any phono cartridge.
    In general, a higher than optimum resistor loading will give a slight tilt up on the higher frequencies.
    A lower than optimum resistor loading will give a slight tilt up on the lower frequencies.
    So if your Dynavector sounds bright, use something less than 47K, but more than 1K.
    If your Dynavector sounds has too much bass, increase the loading resistance to more than 1K.
    The capacitive loading also has some effect, but I'm not as familiar with the effects.

    Sounds like I have some messing around to do. I ordered resistor values from 1k on up, so I guess we'll see what happens. Thanks guys!Very Happy
