You Might want to look at the more advanced but slightly less power Technics SU-G30 also, which uses the newest GaN Class-D amp technology.
It's a network server, Bluetooth, MQA as well as integrated amp and dac
You can find a nice used Yamaha A-S2100 for about half the list price now. I just picked one up myself after several years with an A-S2000. Both amps are polite out of the box but if you leave them on for a few days, they open up nicely. The A-S2100 feels like it has better control in the low and high end. I have a harder time deciphering differences in the mid-range, but my DAC is a mere Schiit Modi Multibit (via USB from a Salk Streamplayer) so that might be why. I'm planning to find a DAC with balanced outputs down the road. Until then, I can't comment on differences between Yamaha's single-ended inputs and its balanced ones.
I pruchased yhr Trchnic on Audiogon for well under 2 grand. I enjoy everything about it, resolution imaging soundstage all are satisfying and greatly improved my system. At 70 watts it could use a bit more juice, but still plenty loud in my listening room. Customer support sucks however you can never reach a person. I do not know the Yamaha but I bet it is good as well.
