I personally have had nothing but BAD experiences with Treo. I use to compete with Treo products until their amps blew up due to defects. I sent 4 amps in and only received 2 back. Treo screwed my team on 2 amps. They lied about a lot of stuff to delay and eventually ignored the situation. It's gotten personal.
Also, a couple of local shops in my area that are authorized dealers have been problems getting warranties with their products. These same authorized Treo dealers are recommending other products because the company is not reliable.
I'd recommend buying, DD, DC Sounds, FI or from other reputable companies. Stay away from Treo.
