Wanting opinions about preamps


I'm just curious what you all might think about a decision I'm needing to make.
I currently have a McIntosh C-45 Solid State preamp in my office with a Mac MC-275 tube amp. It's a great office setup, but I also have a McIntosh C-220 tube preamp new in the box that I haven't opened yet. I really need to sell one of them, but was wondering what others' personal preferences would be between the two preamps. I currently use a C-2200 in my living room system and like it, but I've read some reviews about the C-220 that sat it's a little light on the low end compared to the 2200... I hate to unbox the C-220 if I'm going to end up selling it in the end.
Well... Actually, I'm dying to unbox the C-220 and play with it, but I feel like it would be worth more in the box if I decide to sell it.
Thanks for your input,
Paul

Not meaning to muddy the waters for you, but when I had my MC275 MKV, I had great success paring it with the Aesthetix Calypso with Telefunken smooth plate 12AX7's & Amperex SQ 6922's. I also upgraded the driver tubes of the MC275 with NOS Mullard CV4004 Platinum's and Sylvania Gold label 6201's.
