This entire line of thought makes zero sense.
Why feel bad for selling his gear?
Why did you buy it knowing Topping was better according to you?
ow do you know they can't afford it? I recently reviewed a bunch of Chord gear from a member. Cost? Around $30K. He bought a Topping DAC to replace it all and said it sounded just as good. He was so nice about it that felt guilty to sell the Chord gear to someone else. I suspect money is not nearly as valuable to him as his ethics there.
I personally replaced my $6,000 Mark Levinson DAC (and older multibit one), with a Topping as well. I have more capabilities and have not lost a bit of fidelity. I have however, lost prestige given how small it looks compared the Levinson DAC.
