Buy a violin (or cello or clarinet etc) and join a community orchestra. I guarantee your sense of pitch and detail will improve enormously.
--Ethan
I've been planning to do
just that for a while...buy a violin and learn how to play it at least rudimentarily, that is, not
ruin 
an existing orchestra. Of all the instruments, live violin is the hardest to get just right...CD never has gotten it for me, vinyl has (but
not all cartridges).
I've gotten home from a handful of orchestral concerts in the past couple years and tried to reproduce it in my system as accurately as I (recently) remember it within 30 minutes of leaving the hall....and keep coming up with the
same verdict each time: my CD or (pricey) DAC's owned in that time couldn't reproduce it, and only the Grado cartridges (of 11 cartridges, 2 are Grados) did it commendably in my vinyl set-up.
I recently read the quality of the even the Chinese $59 jobbers you can find on ebay are quite good nowadays...perhaps not Cremona quality, but it'll be good enough, I think, to have an instrument to instruct me nearby for pitch and detail.
Thanks for reminding me to do it, Ethan. I had meant to a couple months back, but life got busy on me
