You may wish to go back and mount your old cartridge in the Graham arm. I was shocked by the improvement with NOT changing to a new cartridge. Most people will have a hard time believing an arm could make so much difference. BTW I was using a Cardas rewired Alphason which I still believe to be a good arm. Much of this improvement can only be achieved by optimization of all the adjustments that are available with this arm.
Skeptics believe:cartridge makes a HUGE difference
I was hesitant to upgrade my tonearm and cartridge. I thought, my system (verity parsifol, MC275, and c2300 with sota tt) already sounded great. Could a new tonearm and cartridge really make a difference? Yesterday, I upgraded to a Graham 2.2 with Transfiguration Orpheous L cart. WOW! What a difference. The records I have heard 100 times are new (and better) all over again. I love this equipment that allows fans of music to unpack more of the music's beauty.
