I have the Totem Rainmakers, powered by all tubes. I also find no toe-in works best and love the wide dispersion. I also find distance from the wall is critical, and closer than a foot has proven to give me a lot of accurate punch without boominess (too far away, they get thin or confused). I add a REL sub when I'm listening more critically, or when there's something big down there, like synth-bass. My amp is 35 wpc, so I'm not crazy loud, but it's not soft, and I've played in bands '-).
The other thing I thought this thread might get at is how a lot of older rock albums just don't resolve to audiophile, even on CD. I've been in studios back in the day where the final mix was signed off on through auratones. Especially in the bass; I often wonder if the RIAA needed to keep it under control so it rolls off. I'll give the Fillmore recording a listen!
