unfortunatlely manufacturers arent looking for that niche customer, or you would be happy. i guarantee you though, if there was a high enough demand for this, someone would do it. im glad outlaw doesnt waste their time or money developing junk like this, so that they can stay in business and make products useful for the majority. while some may suffer, no one ever told you to get out there on the fringe, and as soon as something like this came out you would want to try something even more out there anyway...
you cant overlook the fact that companies are in business to make money first and foremost. we can make a tire that lasts a lifetime, but companies dont because they are interested in selling tires and making money; not putting out the perfect product. why do you think cadillacs cost so much and break down a lot?
if you want something badly enough and you know so much about doing it, then make one for yourself and sell more to the other guys out there who want it. it can be done, and surely you are the best person to do it, i believe in you.
the purist bi-amper would not like this approach anyway, because who wants an amp driving all of their speakers at one time putting out different power at the same time to different channels. they would prefer power pacs as to minimize the length of speaker cables to each speaker. those crazy canucks have been doing it for years and they even make a 60wts and a 120wts which is just what this topic called for.
