Tube rolling in ARC preamps?
I've often wondered why McIntosh preamps are so popular for tube rolling, while many other brands are generally not experimented with.
I used to own a mcintosh c2300, and I tried different tubes with great results.
But my current pre, the Ref 5, comes to mind. I don't believe I've ever read about a single person putting a different brand of tube in their unit. In fact, I don't even know what brand of 6H30P it has? Are they ARC brand? Is there any benefit of trying another brand?
