raul, I must say I'm disappointed by your reference to Ralph as a rookie.
You and I met some years ago and I have great respect for your audio knowledge and that in person you impress as a real gentleman. But some of your replies here seem quite condescending.
Ralph can speak for himself but he has been in the audio business more than 30 years I believe. He may not design and build tonearms but he has the experience of utilizing a number of arms in the tables he builds and modifications he offers. That is not a basis for being labeled a rookie.
He prefers the design of the TP arms, you do not. One thing I've learned in decades of participation in this hobby, there are no absolute answers.
