Fryguy,
Sorry bout the wrong address.. The difference between the 2. HTS2500.. less power handling of spikes, no remote turn on, no digital filter. If you like, you could purchase either unit from me.. i'm down here in South FL.. all you need to do is pay for the unit.. i don't believe that you pay tax when shipped across states, i'll find out about whether or not you need to pay for UPS.. my company is pretty flexible with that!
