i want to click the order button on a new texas star dx1600 sweet sixteen amplifier but im a little apprehensive. the output transistors are dei and i know they don't have a good track record. my texas star 500 with dei's has been running flawlessly so far. now that its been quite a few years have the dei transistors gotten any better as far as reliability? i know that if you run them within spec there shouldn't be a problem, which is how i run my gear but i don't want to pay the million dollars to put Toshiba's in it.
