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

Great stuff, Miller
A prime example of why one should never change more than one item at a time as it makes it much more difficult to define what item had what change, good or bad.
If the Furutech outlets are anything like the SR Blue outlets they will require a fair amount of time to burn in and settle down so may just have to live with it and persevere for a while.

Strongly considering an Urushi Gold myself which would likely be my swansong of carts.
Got a few arms to try it with.
Interesting times ahead......

Exactly what I made in varying sizes so to obtain differing weights from some old brass bar stock I had in my workshop.
Cut into slightly different lengths, clean up edges with a file, drill two holes and all set.
And sitting on top of a black headshell they actually look pretty darn good as well as being functional.

There are plenty of companies making varying weight cartridge screws to start with.
A friend has some on his table where the head of the screw is a large brass knob shaped afair which added a decent amount of weight.
Myself I machined a piece of brass to fit top of headshell with two holes to enable screws to pass through.
Yes you then likely still would need longer screws.

But as a test first a tiny bit of blutac with a penny or dime on top of headshell and see if it even helps before going any further.
