I have to say that cellos sound exceptional on these Triangle Volantes. Warm, dark brown, with all the string nuances. Any brass also sounds great. Lots of bite where it should be.
Aware 'Jazz at the Pawnshop' is one of those recordings that can make damn near anything sound good, but it never fails to harness my (and anyone else around at the time) full and undivided attention when our JA Pulsars place what is most certainly a very real vibraphone right-smack in front of our living fireplace. Never fails to impress.
Had this a lot back in the day. Remember well one time taking a friend along to help him learn how to audition. See how nice the trombone sounds on this one? Much better than those other ones. Piano not so hot. Etc.
Being thorough of course I also pointed out its not really the speakers, its the whole system that's doing this.
