Not just in turntables, but in all components, the nature of the music being played is affected by the failings of the components comprising a system. Different examples of any given component have different levels of failings in different aspects of music reproduction. Music containing a great amount of low-level detail (J.S. Bach’s Concerto for Four Harpsichords and Orchestra, for example) is harmed more by a component somewhat deficient in retrieving low-level detail than is music containing less of that detail. If that piece of music is typical of what one listens to, a turntable excelling in that regard is a priority.
So, what are the characteristics of "Rock from the 60’s like Led Zeppelin" that are therefore a priority in the capabilities of a turntable to reproduce? Decide that, then look for a turntable excelling at reproducing those characteristics. ALL turntables have strengths and weaknesses, better in some ways than others. And different music’s require strength in some areas more than others, and are harmed less by weaknesses in other areas. IMO.
Ralph's (Atmasphere) contention that components being music-sensitive is a myth is not one I can agree with. One example of that argument being mistaken is in the obvious case of the original Quad loudspeaker. I have and love the speaker, and listen to Bach through them, but would not dare play AC/DC at 110dB on them! Turntables are not so obvious, of course, but still.....
