I'd suggest you give a unit to someone to test, IMO thats the only way you are going to get customers like us at your price point. There is a TON of amps that will do a great job at 1/3 the cost, you have to do something much better than another to warrant the extra cost. If the Speaker Power amps really do put out what they say and you have 3rd party results to prove it
I have had some third party testing from pro sound people. http://soundforums.net/product-reviews/1315-speakerpower-torpedo-sp1-4000-plate-amp.html
Granted HT is different. Who do you recommend to test one? It is not easy to do at this power level. I have 50A mains service, a 50A variac, Valhalla 2301 power analyzer with 100A shunt, Audio Precision with burst option, bank of 8 x 8 ohm 1000W noninductive resistors etc.
I would be interested in testing one of the FP14000 clones under the same conditions I tested the real one if someone would loan me one.
