35 watts in Ultralinear vs 50 watts in Triode


I have read that Ultralinear mode in tube amplification provides more slam and punchier sound in comparison to Triode mode. Is this always true? for example, what about a Prima Luna Prologue 5 (35 wpc UL) against the AES Sixpacs monoblocks (50 wpc in Triodo) in terms of bass slam and macrodynamics? is the less powered amp gutsier and punchier than the higher powered amps just for being UL? Is Triode mode always kind of soft compared to UL regardless of power?

Thanks,

Hi Jov

I found that running in triode mode give a slightly more forward and melodic sound. Switching to triode always meant a dip in rated output, but I never found triode to be lacking in power – both my Sli80 and V12 seemed to go equally loud in UL and triode modes.

All thing equal, I doubt seriously 35wpc UL will be more punchy that 50wpc triode mode. If anything, the amp in triode mode would probably be able to be driven harder before audibly distorting.

Personally I would opt for the sixpacs. EL34s are very melodic in triode mode, and if the sixpacs are anything like the V12, it will not disappoint in the bass department.

Having run Manley amps with triode/UL options I found that UL seemed to create a "sheen" or "veneer" over the music. It seemed "harder" Sorry I am lacking the vocabulary to be more specific.

I have always found triode much more listenable and approachable. OTL triode lacks for niether detail or bass slam as Atma-sphere owners will attest.
When I owned Rogue 120Magnums I felt the Triode mode had better midrange with more focus and better depth and more grunt in the bass. I thought Ultralinear was inferior all around kind of washed out and thinner and not that much louder either so it was a no brainer.
