UltraRes version of Cab 103? Or IRs to get there?

[Random Hero]

Is there an UltraRes version of Cab 103? I really like it but I feel it's a little too cloudy in the low end and wondering if the UltraRes deal would clean that up?

If not, can anybody recommend some IRs to get me there? Effectively the same thing but with a little more clarity and a tighter low end.

Thanks!
