I am thrilled with the JJ DV CHI mouthpiece. Tried and bought the 7* tip opening and it is exactly the sound I was hoping for. It is a very free blowing mouthpiece, has good punch and edge to the tone, but without being too bright. Compared to my HR* it is far more free blowing, a few shades brighter but less so than the DV, and LOUD. I'd estimate it's 60-80% more volume for the same amount of effort. It's loud but not harsh and really allows a huge dynamic range compared to the HR* from buttery subtone to blasting fortissimo without compromising control. It also plays very easily in the low end and altissimo. The build quality is very good and despite being used, the plating shows no chipping or wear spots. I've been a fan of JJ mouthpieces since about 2007 (have no affiliation with them) and have slowly transitioned to using them exclusively on every horn but Bari (love my old metal Berg), of the probably 8-10 mouthpieces I've tried from them all have been great quality and the consistency is exceptional which is a big change from my old experiences with various Meyers, Otto Links, etc. that had a lot of manufacturing variability requiring a lot of trial and returns to get a really good one. I didn't care for the included D'Addario H ligature, which I found to not hold the reed very well unless really cranked down. If one is looking for a more contemporary metal mouthpiece that has a lot of edge but is not super bright and allows for plenty of volume in a band, I highly recommend giving the CHI a try.
