Hey there guys, I've been toying with the idea of upgrading my current solid state amp head (Yorkville BM400H combined with a Sansamp RPM) for a vintage tube head. I really dig the Sunn amps. I saw a couple of bands playing those and it all sounded great. I think it would be a great fit for the style of music I'm playing with my current band. We got a post-punk/garage/emo-ish/90's grunge kind of thing going on. On my local listings, there are 2 Sunn amp head that has got my attention. There's the Sonaro and the 100s. The Sonaro is only a 80 watts head. I'm wondering if will be enough to cut through everything. We're only a 3 piece band but my drummer plays real loud and my guitarist plays an old Orange OR120 that can pretty much keep us way behind him. It's loud as f**k. I play through an old Ampeg 810EN. The second one is the Sunn 100s. I assume it's a 100 watts head. It's more expensive, but I guess it should be more powerfull than the Sonaro. Is it worth the extra dough? I know that tube amps tend to be a lot more powerfull when you compare wattage. But when I'm comparing a 400w SS head and an 80w tube head, I don't know where the reaching point is. My tube amp knowledge is pretty limited for now, since I've only owned SS heads. Please bare with me. Any help or input would be appreciated.
