I figured instead of spending a couple hundred here and a couple hundred there for a bit of an improvement here or there, I just went straight to the end and got the jh16's. To be honest, I think the xba 40 sounds really close to the jh16 except with a bit less detail coming from the jds c5 amp. They also have the same quality bass, quality. The best thing though, is that the jh16's bass does not distort, it can handle roughly 8x more bass quantity than the xba 40's.
Other than that, I did not like the jh16's at all when I first got them, compared to the 40's until I got a better source. The xba 40's allow me to enjoy sub-par sources.
