Tube amps that can hande 4 ohmsl


Is this a question I should be asking? Or is it a dumb idea all together? Anyone use a tube amp with a four ohm speakers? Am I looking for trouble?

the Conrad Johnson premier 8 has no problem whatsoever with Dunlavy 5's 4 ohm load at 110 dbc spl.
I use an Audio Research VT 100 Mk II to drive my Magnepan 1.6's with marvelous results.

I HAVE A 30WPC (TRIODE/KT88) AUDIO ELEC SUPP (CARY) SUPERAMP SIGNATURE EDITION. IT IS CURRENTLY DRIVING 2 WAY STAND MOUNTED MONITORS FROM THIEL (NOTORIOUSLY HARD TO DRIVE) THEY ARE 4 OHM & DO DIP BELOW THAT. IT IS AN OK COMBO, BUT I HAVE A SMALL ROOM, & CAN'T PLAY AT CONCERT LEVELS IF I WANT TO. I WOULD SWITCH TO A LARGER, 8 OHM 3-WAY THAT IS EASIER ON TUBES, IF I CAN FIND SOMETHING THAT IS AS DETAILED & ACCURATE AS THE THIEL SCS3'S.
