If you do try a movie with a pair of speakers having a serious and flat LF response, you'll really, really want to put a bass cut in. Movie soundtracks come pre-bumped at the LF end to compensate for the fact that movie moguls know no-one really has big enough speakers for the level of impression they want to make.
No cable grip, so that amplifier's very naughty with a flexible cable connected to it... Just one trip over that cable and you have bare, live, ends on the loose.
HFN&RR spoke to the designer about that meter. Seemingly his previous model had a reasonably accurate meter, but he got complaints that it didn't move much and people thought the amplifier might be faulty (obviously not trusting the evidence of their ears
) So in this model he dispensed with any pretense of accurate measurement and just made it bounce around a lot as an entertainment. An insight into what for all of us is an unaffordable world.
