Tube amps that can hande 4 ohmsl

David Berning ZH-270 otl definitely stable into 4 ohms, no problem. I am currently using them to drive Soundlab Pristine ll's with outstanding performance, the 270 can drive then up into the mid 90db's without strain and they drop down to at least 3 ohms. This is the only OTL on the planet that is able to actually increase its output power steadily as impedance drops. 70W@ 8 ohms (typical output power at onset of clipping 84W@ 8 ohms, 110W @ 4 ohm). This amp has the MOST drive and musicality of any amplifer I have ever heard. It also incredible bass output, unlike other OTL's.

More info on your specific needs would be helpfull. Most tube amps can handle 4 ohm loads; Tenor, Atma-sphere, BAT, Lamm, ARC, VTL, etc.

I think it really depends on the speakers.

My Totem Mani-2 speakers are also 4 ohms, and I am having excellent results with a pair of modded Altec 1570B tube monoblocks (170 wpc in triode).

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.
