High quality 12AX7s bring great sound
2 of 2 found this helpful These tubes look perfect and sound perfect. I bought a matched pair of them from Viva Tubes to replace the 12AX7 tubes in Pro-Ject Tube Box phono stage. I feel a sensible improvement of sound, for instance in bass weight, as well as the overall transparency and detail.
