[QUOTE="Doxquzme, post: 8868525, member: 689267"] Guess we'll kindly agree to disagree. I love my Adcoms with T03s, they sound better than their mosfet bigger brothers. IGBTs (Insulated Gate Bipolar Transistors) are often used in hi-end high voltage designs compared to MOSFETs due to several reasons: [LIST=1] [*]Switching Speed: IGBTs have slower switching speeds compared to MOSFETs, which is actually an advantage in high voltage applications. This slower switching speed reduces the risk of voltage spikes and electromagnetic interference. [*]Voltage Blocking Capability: IGBTs have a higher voltage blocking capability compared to MOSFETs, making them more suitable for high voltage applications. [*]Overcurrent Capability: IGBTs have a higher overcurrent capability compared to MOSFETs, making them more suitable for handling high currents in high voltage applications [/LIST] There availability is a factor, space needed on the boards, different reasons for the use of more modern transistors/fets, not always better, different for practical reasons. That said, was just putting it out there as a viable option in this price range and for comparison of CLASS D amplifiers, not class A/B. The 3000.1 is not class A/B as I'm sure you are aware and it doesn't use T03's so not sure where you are going with that. Personally, it's just to big for my Mazda 3 as monoblock amps go, my very good Korean built Hooligan H-KO3 is big enough thank you very much. I have the Helix B FOUR, available for $175 shipped if anyone is interested. Got my Si SIQ125.4 coming in next week and am super thrilled, if for no other reason that it will be as good and will be even prettier to look at - for about the same new as the as the B FOUR was new. Straight unfettered signal path, large caps on the power rails, nice board layout and attention to detail, all good. Speaking of Helix, watch out for those Helix HXA400 MKII's, probably counterfeit transistors in those too. :rolleyes: [/QUOTE]
