Topping A90 Discrete Headphone Amplifier For sale is my Topping A90 Discrete headphone amplifier. This is Topping's top of the range headphone amp and is regarded as a giant killer of an amp. Purchased late 2024 from Addicted to Audio (receipt available) and intended for a desktop system which did not proceed, so it is barely used. Please also see my separate listing for the matching Topping D90III Sabre DAC. This unit is only a few months old with very little use, and I am offering it at a bargain price, so the price is firm. Lowball offers will be ignored. Reviews: https://www.audioscienc
