Any suggestions on Tube Buffers?

You should aslo check out the Decware Zbox tube output buffer from Decware.

I saw the 283 on their site for $125. Honestly though, all you are doing is "messing" with an already clean signal. Personally, I'd consider a tube pre instead to get a better taste of tubes. I don't think a buffer will give a real taste. It's simply going to softenwarm up the sound a little.

Save for a pre

I agree with above post. I owned an EE minimax BBA, arguably one of the better buffers out there. Inevitably you will be adding another component to the chain and purposely coloring the signal (or compensate for it, depending on how you want to look at it). In the end, I found the resulting sound was more veiled and bloated in the midrange. Removing the unit was akin to hearing what sounded like a 'purer' signal. If you want to wet your feet the right way, I suggest a reasonably priced tube preamp.

I'll sell you my Musical fidelity 3 for $200 + shipping...
