I know the 'normal' route is to throw money at a problem or spend more with an upgrade. However I found out many years ago with my Havana dac that after a pretty short break in of 50hrs or so the 6H3P Russian tube has all the clarity, bloom, bass slam, and midrange of any tube I've tried. Very cheap yet sounds like a million bucks....easily beat my Tung-Sol, Ratheon etc. They found a permanent home in both my Havana and my Orchid.
Best thing is, since they are so cheap I don't feel bad leaving them on, even when I am away.
