Mark Doehmann, the genius designer and founder of Continuum Audio Labs visited yesterday to check my Copperhead set-up.
The arm of the anti-skate lever had not been drilled correctly so that there was no way to attach the arm thread to connect properly. Thankfully it wasn't my ineptness?
At the same time Mark saw the space restrictions which forced me to skew the counterweight to the wrong side, and by moving the Raven front motor to the rear of the deck, Mark was able to create room for all parameters of the Copperhead to be optimised.
So Phaser was correct in his initial assessment and the differences in sound are noticeable although Mark also claimed that even a poorly set-up Copperhead would work at 90% of its potential.
Even better news......in trying to adjust the VTA of the Davinci Grandezza, I found that the shaft was at its maximum extension in the locking collar which thus had little grip and obviously allowed movement in the whole arm pillar.
By inserting a ½" stainless steel spacer under the arm-board that Thomas Woschnick had belatedly sent,I was able to raise VTA and clamp the arm pillar firmly!
The 'bloated' sound has now disappeared and the sound of the 2 arms is much, much closer.
Now some REAL comparisons can begin.
So Sirspeedy and Phaser..........good calls, you were both right!
It was fascinating to hear Mark talk about his theories and designs and also about all the OTHER designs and designers out there? He knows every detail of every turntable and arm in the market....and even those NOT in the market?
Sorry to stray from the topic again?
