I just retubed my Yaqin 13S using Tung-Sol 12ax7 and 12au7 tubes, replacing the Chinese tubes that came with the amp. The change was profound. I now understand what retubing is all about.

The image became darker and at the same time detail and harmonics increased. Also, images became more solid and the bass increased (in a very good way). The sound became smoother.

The most amazing thing was that I played an album that had shredded my ears on all the systems (at any price) that I played it on and now it was smooth and very enjoyable. All my albums sounded smoother.

The only thing I'm not thrilled about is the darker image, but it's well worth it considering the results.

I didn't expect any of this. I wouldn't call it more accurate, but I really like the way it sounds.

I had bought a Denon DL110 cartridge because of it's claims to make everything sound good, but now I'm not sure I need it. It's in the mail now, so I guess I'll find out.

Over the years I would change amps for more detail, clarity, and soundstaging, but this is a totally different animal.
