I do admit that I'm into this stuff pretty fast.
I have the J/spe, kit1, and preamp kit at the age of 21. So I'm almost 25 years ahead of the average 45 yr olds who buy AN?
Unlike you, I did not find the Js very fatiqueing mostly because I heard everything so differently that I was excited to find out how different the next piece would sound. And of course, they were always improvements of what they sounded like before. I'm no experienced audiophile or whatever, but after auditioning for half a year, going from place to place, these were the most musically satisfying pair I have met. I'm not really good at analysing microdynamics or macrodynamics - I'm not even sure what they mean. What's really important I guess is that I'm happy with em.
