Most likely the reason the transistor blew in the first place has not been fixed. It is not enough to simply replace a bad component unless you know why it went bad.

Well, maybe you missed my point. WHY are the ICs blowing? Have you completely tested out the REST of the amp to make sure there is noting wrong in the power supply, in the input side or the feedback circuit, or elsewhere? Just replacing what's blown only works sometimes.

Is it worth repairing? Starsound amps are not usually that expensive anyways. Just wondering if all the spare parts and time is worth it.
