A BAT PACK option is simple... it provides a greater power reserve. In other woreds, within reason of course, it will not run out of steam (headroom) with the majority of musical passages on the larger majority of speakers. the overwhelming majority of the VK500 SS amps were made with the BP option.
The reviews I've read on the Belles point them towards being solidly more a neutral sounding amp. there's nothing right or wrong about either choice, warm or neutral... it comes down to what you, and your system needs are presently.
If currently your deal is a mite hot up top, or thin elsewhere, warmth might be in order. if things however are really full and fleshed out, neutrality seems the ticket. IMO. If bass is key for you or you're a bass junkie I doubt you'll get what you seek going with tube amps without adding a nice sub.
I know the vk500 has plenty of bass, and the reviews on the Belles indicate they do as well... some models more than others.
Both companies have outstanding customer service and build quality.
having a tube pre will give you some latitude too in attaining the sound you seek if an SS amp is added.
