Butler TDB 5150. SE only though. Affordable, suprising sonics and control talents, and there's no mistaking the infulence of tubes it uses in it's hybrid design.
you'll sell the Anthem pretty quickly thereafter. the Accupase will continue on in it's environment and you won't be out much $$$.
50 lbs or so, stable, and doesn't run hot. Transferable 5 yr PL warranty from orig buyer too.
I often use it for 2ch along with my tubed preamp instead of my Dodd tube mono blocks as it's a plug and play affair with no need for bias checking or adjusting.
For a single one box remedy I can think of no other in it's price point (preowned or new) that competes so well.
When in 2ch the power revs up to over 200wpc @ 8.
Given your tastes, it's a good fit for you to peruse huybrid designs... be it Butler or some other brand.
Good luck.
