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

thank you to all who took the time to answer my questions. I've read somewhere else that adding mass to the headshell improved the sound of the black cartridge. What is the best way to add mass? I've read about people adding pennies to the headshell, which sounds a bit crazy and not something that I want to do. Is there a product out there for adding mass?
thank you
