+1 for Topping E30 - it bests D30 in measurements and costs only $30 more. It also has remote, volume control mode or DAC-only mode (fixed volume), input-sensing auto on/off. D30 uses Cirrus chip, where E30 uses AK4493 (better chipset) - as @djones51 said above.
All this makes it more usable for other purposes (computer desk, office, etc) when your units comes back from repair.
