I think it sounds great ... LOVED the Jazz Trio ...
It sounds very good, but to be honest, so does the pa3x..
And it adds some new things, but there is also a lot of things stepping back from pa3x
- expansion PCM drops from 512 to 400 MB, there is no more build in lossless compression
- which removes backward compatibillity to pa3x (compressed)expansion sets
- there is no 2nd keyboard split
- there is only a single insert effect shared by the 4 keyboard parts
- there is no more motorised tilting screen
- where the pa3x was much cheeper then the T5, this one is more expensive
In the end, the pa4x is a mixed bag of feelings...
