The BasX A-100 offers all the essential features that make a great audio component, like a heavy duty power supply, great sounding high-current short signal path Class A/B amplifiers, industry standard unbalanced audio inputs, and full-sized five-way binding post speaker terminals. The BasX A-100 delivers a solid 50 watts per channel into 8 Ohms and 80 Watts per channel into 4 Ohms; plenty to drive most speakers to satisfying listening levels.

It has LOTs of power, like you said, but also LOTS of noise relative to good $100-$150 headphone amps and a high likelihood of channel imbalance. The recent Audioscience Review test
[audiosciencereview.com] shows distortion at .012%, Noise at 78dB below signal, and about .5dB L/R channel difference at 5W (likely higher at headphone volumes).
By comparison the $99 Schiit Heresy has .0007% distortion, Noise 103dB below signal, no channel imbalance...and PLENTY of power for 99.5% of all headphones. Plus, the Heresy has an external gain switch, so you do not have to open the chassis anytime you want to switch between high/low sensitivity headphones.

Nuanced? I prefer liquid, crunchy and transparent. I love audiophile lingo.
Probably because it "measures" so poorly according to that guy at audiosciencereview. Some ppl don't care about specs and only care about how it sounds. Others do care. To each their own.
You'll need a phono converter unless your turntable outputs rca.
You can hook a sub up to the line outs.
It's a little sad to know that if it goes it might be hard to replace; hopefully there will be a similarly-situated replacement amp.

Just keep in mind, those outputs are fixed, so you'd need to control the volume at the pre-amp, and not through the A-100's volume knob.
Me neither. The components used in this little thing are much better than most of its close competitors. For example, most amps at this price point have almost the same output at 4ohms than at 8ohms. I believe this and a denon dra-something are for the most part the only $200-ish amps that can do a decent job when paired up with the magnepans LRS.
You will have to find an amp with discrete outputs (rca) that will play on both discrete and regular outputs. I'm no expert, but I've only heard of home theater receivers doing this. Usually any amp you plug anything into the headphones jack will stop sending sound via any other output. There are other options like splitting the sound signal before it gets to the amp, but that depends on your config.

Wrong. You can wire all those speakers with this amp. You wire two sets of 6 in series and then wire those two sets of 6 speakers in parallel. Then do the same for the other channel. You will be reducing the amperage going to each speaker by a LOT, but if they're very efficient speakers and only require a few watts each, you will be fine.
It's the same way people wire multiple subs to a monoblock amp.
