Topping DX9 15th Anniversary DAC&Headphone Amplifier AK4499EQ Hi-Res Audio Support LDAC with Remote Control Decoder (Silver)

Never worked. Wanted for tax evasion for work. Blamed me for sending the correct invoice.

I've had every Topping product before this, and it's a worthy successor to the DX7Pro+. Perfect channel balance and the same power as the L70 stack on the balanced side. On single ended outputs it's 2 watts into 32 ohm, which isn't unlimited if you've got the 600 ohm Beyerdynamic headphones. Equalizing those takes more power, so the A30Pro would be better.I've had the A70Pro, l70, A90 and A90d discrete. The sound is most like the A90d stack. It's much better looking than a stack, if you want state of the art performance and sleek looks.My favorite is the original A90/D90SE with its smooth volume and big soundstage. You can't go wrong, but there's stacks like the E50/L50 that's much less expensive.If you can afford it, you won't regret it. If money is an issue, there's better value to be found though.
