Headphone output on the Mcintosh C2200


I recently purchased a new Mcintosh C2200 (Frank Gow commemorative) from Audio Classics. I am extremely happy with it but find that the headphone output seems to be extremely low (I ahve to crank the level up to 60 or so to really hear it. Is this normal ?. Many thanks in advance.

Headphones may be more of a personal choice than speakers, that being stated I would easily recommend.....Grado { I have the Grado 325is}, Beyerdynamic, and B&W headphones. For a headphone amp the Schiit brand among a few others draw my attention. Your headphone input on your pre amp may preclude the need for a dedicated amp. With the proper headset impedance for your pre amp, you may find it too be excellent. Happy hunting.
