Make it an even 1k and find a Wadia 121. Everything else you've been thinking about won't come close. The Bi-Frost is a solid recommendation on the cheap however, so if you are sticking to 300 that's a safe bet.
But if you can spend more you can do better. Depends on the rest of your system of course. The Wadia is wide open and neutral so if you're looking to warm up your system it's not the ticket.
