@waltersalas I own a pair of Nord One Up Class D Monoblock amps that I love as well as my Art Audio Diavolo SET 300b Tube Amplifier that I switch between using a LUXMAN AS-55 high end amp switcher. It allows me the best of both worlds and saves my tubes from unnecessary wear when I'm not critically listening or watching a movie or tv show. My thought is that I'll eliminate my Benchmark DAC2 HGC as a DAC and preamplifier altogether and use the tdai-3400 as a dac/preamplifier/room correction to feed my Diavolo SET Tube Amplifier and using the Luxman AS-55 amp switcher I can redirect the tdai-3400 amplifier's output to my Encores for the times I'm in the mood for tubes. It's this versatility and simplification that appeals to me the most.
The best case scenario is that I love the tdai-3400 so much that I'll sell the Nords, Benchmark DAC2 HGC, and the Diavolo SET Tube Amplifier altogether, but if not I'll just sell the Nord monoblocks and my Benchmark DAC2 HGC and keep the Diavolo in the chain for the times I critically listen to particular genres of music that benefit the most from it glorious mid-range.
