Jim,makes me want to upgrade to the Master also! WOW! I'm glad you are so thrilled with your music.Yes,the Grado's are very fine cartridges.Enjoy!!
P.S. The Grado's need about a good 30 hours to really show their stuff.You aint seen nothin yet!
Sell your Rega 3 and get a used 25. If you got say $600.00 for your 3 and got a 25 for $900.00 that would leave you enough for a Grado Sonota and that combo would kill the 3/master combo. It never ceases to amaze me how few Rega table owners use Rega cartridges. Smart group.
