Hello Miguel,
In all candor, adding your Tripoint Troy to my system is one of the best audio related decisions I've made. It took what was a musical experience I loved with my system and genuinely increased it! Only problem (a negligible one) is I can't explain to anyone "how" it does what it does. My ears and visceral response to it confirm that it's doing something utterly special. I thank you for making this superb product.
I haven't heard the First Watt SIT amps but I'd imagine that they're exceptional given their builder's considerable talents.If I were to ever consider owning a SS amplifier this would likely top my short list along with the class A Valvet mono blocks
I did hear the 300b SET Electraprint driving the Cessaro horn speakers at CES this year and I was extremely impressed by the sound and realism. This room produced more dynamic energy,life like presence, tone and involvement than any of the other rooms using mega watt amps driving big inefficient speakers. Those types of systems just lack a degree of naturalness IMO. I believe that you'd really like the Electraprint amplifier.
