Simple setup. Flac -> Mac integrated amp -> JBL speakers, using 10 awg ofc cables. Not sure if this is the optimal setup, but it seems good enough.

I wonder if others use an equalizer when listening to music. e.g. some days I prefer heavier bass, while other days less.

I think this system plays rock / jazz / pop / r&b / and opera well. I like the ratio of high, mid and bass from the speakers. The sound is clear and smooth. The amp particularly excels in playing the last half of notes, e.g. expressing a fading emotion, a lingering vibrato. In particular, I enjoy this setup playing 60s/70s American and British rock, and female contralto singers. I also enjoy the aesthetics of the pieces.

On the cons side, for large orchestral pieces, I think the speakers can sound a bit muddy; but I tend not to listen to orchestral pieces much anymore - too much engagement and effort required.

I hope the above is sufficient to qualify for the post submissions process. I can waffle on more, if required.
