Just happy to help I wish we could find a better font for the DX50, text really looks atrocious. Problem is, it needs to support latin, korean, japanese, chinese and probably sanskrit as well. Not many of those around.

Knock yourselves out, this is a good one.
In case you were wondering, the finicky Heir Tzar 350 sounds decidedly delicious out of the PB2! Still on low gain, I have the volume control at just under 50% and everything is squeaky clean - assuming your source material is of proper quality.
