Hey everyone. I have a line6 spider2 112 75 watt amp. would it be a good idea for me to sell it and buy a Vox AD15VT?

Also, would it be better for me to get the Vox AD30VT instead of the 15? If so, why?

I was wondering if, when the amp is turned up, whether the sound gets better or worse, as I know on a real tube amp the sound gets better, and a SS amp it gets worse, so how about this? If it gets better as it's turned up I'll get the 15, but if not I may get the 30.

Thanks in advance, I may post more questions if I think of any.
