Koetsu black, lacking bass


Greetings 
i just installed a new koetsu black cartridge. I love the clarity of this cartridge. I was using a lyra kleos , which is a great cartridge but the clarity of the koetsu black is at another level.
does anyone know if the black cart is light in the bass? It seems to me that  the bass sound of my system has diminished with the koetsu. Is this a break-in characteristic? I should mention that I installed a furutech gtx outlet which is still in the break-in phase. I’m using a clearaudio magnify tonearm with a clearaudio performance tt. My preamp is a McIntosh mp1000 with acoustic zen ic cables. Mcintosh ma252 amplifier, focal aria 948 speakers with transparent super speaker cable. Any insight and knowledge would be helpful and appreciated!
thank you

Try adding one, two or three US nickels to the headshell. Each weighs 5 grams. You may then need to add some weight to the counterweight to adjust the VTF(2.5 grams).
Consider getting a high-mass arm. I have two for use with mc cartridges: Fidelity Research FR29 and FR54. I agree with mulveling that the Clearaudio arm is suspect!
