I listened to Alta Audio Alyssa at an audio dealer (that I highly respect). I found them thick sounding... too much mid-bass for my liking.
@audiojan The reviews I’ve read of Alta speakers indicate they are a bit polite sounding up top that may also be feeding into your impressions, but it almost sounds like the speakers weren’t optimally set up in the room or maybe an equipment mismatch. What do you think?
Anyway, the more polite house sound of the Altas is why I recommended the Prism and Mini-X above as they probably offer a lighter/airier perspective in the event the OP finds the Alyssa not to his liking/tastes. All comes down to personal tastes after all. Frankly, at $5k and as @blisshifi alluded to above, I’d go for a pair of used Pulsars and call it a day, but that’s me.
