If it helps at all, I just found out about these Cadence amps... They are the first gen with short heat sink fins, so they could possibly have over heating issues when pushed hard... but for the money they are VERY hard to beat.. Cadence is a good company with a good reputation.. you can purchase factory direct from Cadence as well, if you are worried about warentee issues... (If you look in the outlet store, they have some nice deals..)Hear is the deal link..
