Sounds excellent no doubt! But I also like the warm sound the T4 and the unplugged/acoustic sound of the PA900.

I have to admit that had this of been 10 or 15 years ago I would have probably dropped everything and went for the Audya - similar to what I did when I let go of my PSR8000 in favour of the Solton X1. It didn't work out for me then and I think it would be the same for me now! I'm really happy with what I've already got but no doubt the Audya is a superb sounding instrument.
