I purchased the Topping A90D amp 2 weeks ago. It sounds awesome that says it all. Also great customer service from Apos. I paid $599 and a few days later the A90D went on sale. I contacted Apos and they refunded the price difference. Thanks Apos. James R.

James · September 5, 2024

I discovered Topping late last year and did my research. The multiple reviews from everyday people plus several known Audiophiles helped me make my decision on the D90 Headphone Amp & A90 Discrete Stack. The build quality and sound is next level for me. I'm just a guy that loves to hear music as close to the way that it was recorded as possible within my budget. The sound that's coming thru my ZMF Caldera's & Barefoot 2 are pure pleasure to say the least

I it worked for three days and it overheated and had to send it back
