    Not a problem under normal music conditions and an 8 Ohm load. My amp is in an even smaller case.

    There's a massive thing here about TPA3116.

    I've read most of it over the years, fool!

    I've tried many, most work well.

    Currently using a NUC power adapter 19V 3.42A which seems ok with the MS400, they seem pretty efficient and rated around 30W max anyway.
    Will check it out after a prolonged session.
    A mainly digital setup with a musical amplifier and endearing 1970's speakers. A CD player that hardly ever gets used and a turntable that is good enough to remind my how enjoyable my old vinyl is. Some cables and things.

    Should be fine, you should have more than enough output with those speakers in an average room.

    I always check the output voltage of these supplies, just in case there's a rogue one that's out of spec.

    Yes. I do that too.

    There is one point that is often overlooked, most TPA3116 have their output inductors optimised for a lowish impedance, say 4 Ohms. If one uses a higher impedance speaker, a very mild treble lift will occur. Even driving my clone 15 Ohm LS3/5a's it's hardly detectable.

    World's cheapest passive pre-amp just arrived. Bought for a bit of fun, sounds OK though. Way better than you'd expect actually!



    Cost me a whole 3.14 delivered and only took a week and a half to arrive.

    Link here if anybody is imterested.
