I view my multiple tables, tonearms, cartridges like Kurosowa viewed reality in Rashamon: a matter of perspective, each one compelling on its own terms. Part of the fun is working with the various combinations until they realize their own coherency, they're own flawed perfection, their own best character. Then they speak on their own terms and I'm convinced by their narratives.So beautifully put Wrm57.
I think the mistake is to believe that there is one 'right' presentation to audio?
As Suteetat so aptly points out........there is no one 'right' presentation to 'live' music?
I would like the ability to switch in a valve preamp and/or amp to replace the solid state ones in my system from time to time?
I would like the ability to move in some electrostatic speakers or horns from time to time to replace my dynamic ones?
But these substitutions are rather impractical for me and many others I presume?
The differences in 'presentation' these substitutions make on the same source material.......lead to an enlightenment or deeper appreciation of the possibilities in this wonderful hobby of ours.
With but one cartridge and tonearm......we must accept the benefits and beauty but at the same time....the limitations and deficiencies.
Much as we do with our wives or partners :-)
A collection of cartridges may be somewhat analogous to keeping a harem?
