I honestly haven't had a chance to hear the H80A yet. It would be good to run a comparrison when one arrives. I have heard good things about the H80A whether the XTZ amp will be able to compete remains to be seen.

The products of Cayins i have heard are the ones we have available for home demo which are as follows:

A55-T Integrated Amp
CD50-T CD Player
A100-T Integrated Amp
500MK Integrated Amp
220Ti Tuner

We are expecting the SP series (retro) to arrive end of October along with some other peices as we are waiting for them to be ready from Cayin which should be end of next week.
