    So, i bought this beautiful and well kept matching pair of Technics SB-LX70 speakers.
    The speakers power handling is of 100w at 8ohms.
    Now i need an amplifier to drive said speakers, but how many watts i'm gonna need?
    I was thinking about buying a Pioneer SA-7500, maybe an Akai AM-35 integrated amp, but i'm not sure if those can manage to deliver enough power to drive the speakers...

    Found this spec page on your speakers...

    According to that - these have an efficiency rating of: 90

    SPL, 1 Watt/ 1Meter, dB - will produce 90 dB of sound....

    "The speakers power handling is of 100w at 8ohms."

    Those numbers don't mean too much --

    Looking at what you are trying to drive them with:

    Pioneer SA-7500 - Stereo Integrated Amplifier (1975-78) - Power output: 40 watts per channel into 8Ω (stereo)

    Akai AM-35 - Stereo Integrated Amplifier (1990-91) - Power output: 60 watts per channel into 8Ω (stereo)


    Either of these should be fine - if you are worried about power output, go with the Akai and get a little more head room.
