Re: 12AU7 as a buffer - suggestion of brand/model.

Someone previously mentioned the Tung-Sol 12AU7 (the older variety from the 50s) and my experience with them mirrors his. I would describe them as having a very solid bass foundation and a rather big sound. One of very few notable 12AU7s in my experience. The whole 12AU7 family of tubes suffer from mediocrity.

To address the lack of resolution and liveliness, I would suggest that you roll the 12AX7 tubes in your pre section, if it indeed does use 12AX7 tubes. I think the potential to change your sound more toward your preferences rests with this tube as opposed to the 12AU7.
