    Question about using an adapter for the Sony MDR-1AM2.

    Hello! I intend on purchasing a DAC amplifier soon to plug my Sony MDR-1AM2 and other Hi-Resolution sets into in the future.

    Stax SRM-1/MK2 Voltage Switching

    Left channel hum...driving me crazy

    Not sure where else to post this, but my SRM-1 Mk2 Pro has developed an infernal left-channel hum/buzz (sounds like a very quiet 60hz sawtooth wave) that is dependent on position of the volume potentiometer. I Thought it was a problem with a filter cap at first (electrolytic, installed a few...

    How does the Woo Wee converter+poweramp compare to SRM-252?

    I'm about to sell my whole setup to finance stax lol. I'm still not sure it's worth it. I could afford it if I just got the 3100, but I want to get the Woo Wee converter and a good power amp, for clarity and soundstage. I'm probably gonna get the Parasound Z-amp v3 as a power amp, run...
