While I have not used the 320bee, I have owned the C720bee which to my understanding is a 320bee with a tuner. As the upgrade bug hit, I added the C272 power amp but still used the pre-amp in the C720bee. Then when the prices fell, I ended up sending the C720bee to my brother and I purchased the C162 pre-amp instead.
I'm new to this hobby and my ears don't pick up on the same details as most of the members of this forum. However, moving to the C162 pre-amp made an improvement to the sound that I could hear immediately. I hate to use these words because I think they are over used to a point, but the 'sound stage' really opened up in my system with the C162 and had more 'depth' to it.
I've not compared the C162/C272 combo with the C372 so I can't comment on that integrated. If the pre-amp section in the C372 is the same as the C162, then I think you will find an improvement with the C372.
Hope this helps.
