Has anyone used Herbie's tube dampers or other tube dampers on the DHT tubes? If so, can you report your findings? Thanks!
Yes, I use them.
They work as well as they did for me previously with signal tubes (6922, 6SN7, 12AU7) or power tubes (6AS7, EL34, or 845):
- They cleaned up the sound up and down the spectrum
- Improved detail, imaging, and soundstage
- Provided a more focused, yet musical presence
No, they won't fundamentally change what the LIO DHT tubes are, but they will help them be all they can be.
