My 2p
The problem with any of these is that the DAC is what it is. It’s tied in to the amplifier. Why not get any amplifier that meets your power requirements and a separate DAC (which can be replaced later if required).
Also don’t limit yourself to 2 channel amps. There are plenty of cheap ish AVRs (5.1) that can be configured to operate in 2.0 modeIt is very difficult to predict the life cycle of a product.
I'm sure Mr EE will have some suggestions, but I'll also have a few suggestions.
With DAC
YAMAHA A-S301
DENON PMA-600NE
MARANTZ PM6007
No DAC
Topping PA5II + ( WiiM Pro plus ) or (Wiim Pro + DAC [ SMSL SU-1 ] )
SMSL AO200 + ( WiiM Pro plus ) or (Wiim Pro + DAC [ SMSL SU-1 ] )
The PA5II is very high-performance, but Chinese amplifiers have concerns about quality and support.
