I think you're going down the right route by looking at Barefaced. If I ever replace my combo, then I'd seriously consider BF.
Ampwise, I'd take a look at Markbass. There's a good selection on here for bargain prices, from LMIIs to LM Tubes & a good selection of others.
Also worth a look are GenzBenz, TC electronic & EA for small lightweight heads.
If you're near Dunblane at all this coming Saturday, PM me & you can try my MB combo & see if it gives you any ideas.
