Thanks for the info.
I ended up getting the Dragon MK I. It does some things better than the Pass Labs XA30.5 and the Pass did some things better. So it is a mixed bag.
The pass has better bass, sounds fuller, and has more weight or umphff to it.
The Dragon has better separation, more 3D, and very smooth, which I really like. However, it sounds a little thin compared to the pass amp. As a result it has less bass drive.
Any advice on how I can tweak the Dragons so they produce more weight to the music?
Thanks,
Ernie
