Bat vk31se and vk120 vs Simaudio I-7

Can anyone share some insight into how the two systems compare?

I have the BAT vk31SE and VK120 monoblocks and the sound is very nice and musical with Esoteric player. However, recently I had the opportunity to hear Simaudio I7 integrated amp with their Nova Super Nova player and was very impressed. For an integrated SS amp, the sound was full, really nice and Jazzy. Ofcurse, this was at the dealer, our speakers are the same but rooms, PLAYER, cables and treatments are completely different and they won’t let me connect my gear to the I7 unfortunately which would provide for a better frame of reference :(

Obviously these two systems are quite different (BAT tubes and i7 integrated), but I am considering the i7 based on the cost savings and ease of operation (class A preamp, class A amp to 5 wpc class AB at over 5 wpc), without the Super [expensive] Nova.

Perhaps, someone already had both and did the compare? Appreciate your thoughts..
