I paid $389 for my C1 pair new on Amazon about a year ago, FYI. Sealed is nice for desk and with only 8” behind. They are currently in my main HT system, which maybe could be considered a promotion from backup duty in my third music system, where the Kefs are (or maybe a lateral move, haha). If your amp is neutral or laid back, the C1’s should be fine. If your amp is forward, then maybe not.
