VU + Solo 4K vs Ultimo 4K and Duo 4K?

[olddroid]

I've had a Solo 4K since it came out. I want a new receiver, but I must admit I can't see any big advantages in Ultimo 4K and Duo 4K? Can anybody tell me what's better with the 2 newer receivers...?

A simple question, posted thousands of times, and an almost impossible answer: everything is subjective.
For instance, even if Duo4K is more powerful, it has too few slots for my needs.
Look at the specifics in the vuplus website and you should get the answer, based on your needs.
