The Millenium HP4 is a surprisingly capable budget-friendly headphone amp for smaller studios or anyone needing to manage multiple headphone feeds. Its independent channels are a huge win, making it great for tracking sessions or monitoring multiple engineers. Don't expect audiophile-grade performance, but it gets the job done reliably.
