Having multiple amps to cover different venues and genres is the way to go.
Last 10 yrs or so I've kept 5-6 amps (most vintage) in my stable that will cover damn near everything I do or will do.
Funny thing is... IMHO my most versatile amp is an HRDeluxe III with an extension cab. Had it modded by a wizard of tech and the drive is stage-worthy, & through my own trial and error with tubes and speakers have come to really enjoy that amp. It's not that it sounds better than my vintage amps, it just does everything well and it's easy to dial in live. plus... Never has given me any trouble, been a workhorse like all my vintage amps.
I've never had an AC30 but do know their thing and that they are LOUD. Don't know how an AC15 or other Vox compares, or if excessive volume is even an issue in your space.
To crank up an AC30 properly you will need a very large music room. Like Auf Kiltre I have never owned an AC30 but they were always available in the rehearsal rooms I used in the eighties and early nineties.
