For context, my main rig is an SVT + 810. I like it a lot. I play rock/metal.
I want to get something smaller for where the big rig isn't exactly appropriate... basement rehearsal, livingroom jams, gigs in the attic, stuff like that.
I'm leaning towards a PF500+PF210 or an RB210. Maybe even a Micro-VR. I'd like the ability to eventually throw another cab under either option.
I'm not looking for smallest/lightest possible, I'm looking for best quality sound at around the size of a 210.
Could also be talked into a 115 if it'd sound better than the 210.
I'd suggest you grab a DNS-210 by DNA if you can find it. Trick is going to be finding it. David has been "shuttering the business" due to parts no longer made that he used in his amps. He actually made a DNA-800 for me in 2021 when his factory didn't have any completed amps on hand and were waiting on parts. He had the parts on-hand himself, so he built one for me. Unfortunately he announced he was "shuttering the business" a couple of months ago.
New, the street price for a DNS-210 was $849, I see one of the newer ones for sale on Reverb for $549. I use that 210 for all my indoor venues because it's super clear, clean, articulate, and damn LOUD! Bass response will play a 34Hz fundamental and bottom end sounds tight and focused, not boomy. It handles 700-watts rms and mine is an 8Ωone because I have an old Eden WT500/800 amp that bridges at 800-watts into it. I've never needed to run the master on the Eden above 10:30 even in the largest indoor venues.
Besides that big class A/B Eden amp, I also have a DNA-800 class D amp that will deliver 400-watts into 8Ω or 800-watts into either 4Ω or 2Ω. So far, I've used that for my small and medium gigs with my DNS-210 and that 400-watts is more than enough to get it to giggable levels. Haven't played a large venue with it yet but I think it will be fine. I can run both my DNS-210 and my DNS-410 with it at the same time if I want, but have never needed to use more than one or the other. Did stack it once when I first got it in 2019 because I wasn't sure the 210 would handle that size room on its own. My 410 just ended up being an extremely expensive amp stand for that gig as the DNS-210 was more than enough.
Weight is 51-lbs which is heavier than many 210's and it's also a little taller box than many, but it has taken the place of my 410 in ALL my indoor venues too. That saves lugging around a 410 for large indoor venues. For outdoor venues and music festivals I still use my DNS-410, which I bought in 2015. By the way the older DNA cabs have a Silver and Black logo like the one on my DNS-410 and the newer ones have a Gold, Silver, and Black logo. The one I just saw on Reverb has the Gold one.
Here's my DNS-210 with the 800-watt Eden amp that I run bridged into it. I bought it in December of 2019 and notice that it has the gold Logo.
