I just spoke to Sunfire regarding some other matters and asked about this amp. The Lightstar was built by Carver Corp AFTER Bob had sold the company and started Sunfire. They basically worked off of his early design notes for the Sunfire amps that he was working on and came out with the LightStar. As such, i was told that it is VERY close to the Sunfire but is voiced slightly differently due to having two "different" companies building them. Whereas the Sunfire's were voiced by Bob to sound a little "airier" and "smooth", the LightStar is supposedly a little more neutral. While i didn't ask about Sunfire servicing these amps, i got the impression that there would be no problem with that whatsoever. By all accounts of what i've been told and been able to find out, this should be a "kick ass" amplifier for a reasonable amount of money. Hope this helps... Sean
