Sean says a lot of things I agree with, among them his statements "Im not in love with the sound of convention" and "playback is not live"
I believe his goal is to design speakers to impart a sense of excitement and realism he feels is lacking in what he has heard elsewhere.
Regardless of what you think of his speakers, its a path I admire.
I think some "audiophiles" try to chase down this holy grail of the live event in their listening rooms.
I would assume Sean considers playback like watching a movie, you know its not real but you suspend disbelief and enjoy it without picking apart every scene. But this is no substitute for getting out and hearing real music in a live setting.
Live can sound far from the perfect realm of reproduction by a high end audio system, none the less live imparts something not captured in the playback chain.
I get to see my 18 yr old sons band play at a local venue a few times a month, while those huge bass horns and monitors on the stage are not hifi, the impact and immediacy of the raw performance is fantastic. From the rim shot of the drums to the driving deep feel in your bones of a bass guitar and the screaming over driven tones of my sons Strat coming thru his Fender tube amp, its an experience that is hard to match in a home environment. Still after a night of listening to some local talent at our local watering hole, I have no problem turning the lights down and enjoying my favorite recording from my listening chair.
Here is Matt and his band The Pool Rats opening for Eric Steckel on a Saturday night.https://youtu.be/pKOv6QnBy40https://youtu.be/TiXGTrr-Sz4
