@grannyring I've been a SET fanatic for 20+ years, The flexibility of using the TDAI 3400 as both a DAC, Roon Endpoint, 400w amplifier and preamp to feed my SET amp plus the room correction are the reasons I bought it. I sometimes just feel like listening to certain music with a set amp and at times I crave the power from solid-state for bigger pieces of music. This solution allows me the best of both worlds using my Luxman AS-55 amp switcher to feed the Encores either tube and solid-state output effortlessly which is my main goal. I'm all for the idea of TDAI-3400 replacing my SET amp, but I'm not holding my breath because on certain pieces of music the sound my amplifier produces is just glorious in the mid-range and excels on female vocals, jazz, small acoustic pieces.
I'll be very pleasantly surprised if it this piece replaces my tube amplifier.
