I am rather certain my amp has more than enough power. The speakers [4 Ohms] are rated at 250 RMS. Amp requirements are 100-250 W. All as per manual specs. Michi pumps out 350 into 4 Ohm. So no worries there.
I also contacted both companies directly to confirm the match prior to purchase. Both said it was a perfect match. In fact higher power from the amp is safer than less, as per both contacts at both companies. [Which we all know]
Cartridge compliance?? What? I stick a Rega cart. on my Rega arm. No brainer there.
Its almost as you are trying to wind me up.
