I Have owned an Esoteric C-03x pre-amp for about 5 years. I have the itch to upgrade and found these 2 preamps are in my price range.

I was talking to my local dealer and they recommended an LS28SE over the C-03XS. I know the LS28SE has tubes.

Has anyone had experience with both of these. Is the LS28SE a good way to go.

I would be pairing it with a K-03XD and Bryston 28B3's.
