I have for sale a used PLB-AMP8 by Phast. I have used it for a few years to power my zone two out door speakers and zone three kitchen speakers. I am moving to a new house and no longer need this item. I am asking for 325$ including shipping. If you have any questions about the item shoot me a pm. The unit is well documented on the web so if you want to know more about it you can do a search on google.
