That's a great amp to my ear. Obviously, the statement is practically useless for your evaluation. More detail from this end doesn't really help, because your technique, style, instrument type, band type, and venue type are all unknown.
Personally, I would drive the four hours, take my bass and cab(s), and try the amp in question. If you like the amp and buy it, it's the beginning of a good history, and you will enjoy and use it for many years. If you don't like it, there are probably many music stores along the way to preview other gear.
I drove ten hours to preview a fretless bass about five years ago. Today, this bass is my fave and trusty workhorse for practice, recording, and gigging. The initial drive time was a minor investment for the enjoyment and use it has returned.
No person here has your perception and ear. Trust those!
