I'm not so sure I understand why every one is down on a tube buffer. While I have no direct experience with one, most (not all) of the user reviews I have read are positive. Stan already said he can't afford to make major changes in his gear. $100 for a used T.Buffer is worth the risk and its cheap. It may help some with warming things up, improving bass, sound stage and transparency- and I used the word may!

The first epinions review I posted gave a good review on the Yaqin buffer with magnepans and good equipment.

At worst he's out shipping cost's because he should be able to turn around and sell it for what he paid for it.
