I also play rock at times, ranging from Steely Dan to Foo Fighters to Pearl Jam to softer stuff like CSNY or Van Morrison. All of it sounds more present with the Safir (and my current cartridge which is a Koetsu Rosewood Platinum.)
For what it's worth, I know of someone else who planned to add a second tonearm, but after a month with the Safir, simply didn't see the need.
