Around $2K on the used market, the Denon PMA A110 and Yamaha A-S2100 are hard to beat. IME, both are competitive with integrateds in the $6K-$8K range from other brands. As an example, both have a lower noise floor than the Luxman 507z. The Yamaha produces deeper bass and sounds more powerful despite the lower power output.
I owned the Hegel H190 for a time and found it was overtly warm and rolled off in the highs. It also had an unacceptably high noise floor for an integrated at its price point, even at secondhand prices. All the lower priced Hegels run quite warm because they cram a bunch of transistors onto a single heatsink that really isn’t up to task.
