At US$400, the Topping A90 Discrete is a standout bargain compared to the obvious alternative at this price point, as it sits well below the 25th percentile of US$439 from your ground truth used listings. With the median asking price at US$473 and the 75th percentile at US$502, this listing represents a genuine strong deal that most enthusiasts should seize immediately.
This amplifier is widely celebrated as the "best-sounding headphone amp on earth" for its price, offering transparent, powerful sound that easily drives high-end headphones like the Susvara. Its dual role as a fully balanced preamplifier adds significant versatility, and securing a well-loved product like this for US$400 is a rare buying opportunity rather than a risky move, especially given its pristine build quality and dynamic performance.
