After living with and enjoying a Benchmark HPA-4 for a few years, I added an ARC LS28SE. It has the very high resolution and extension in the low bass and upper treble as the Benchmark, while "adding" just a bit of tube glow. Nice!
The ARC also has all the inputs and outputs ever needed, including a fixed "tape" output that now feeds the HPA-4 which is used only to power my Meze Elite headphones.
Used, it meets your price target.
