EL34 SE as stable with complex music as EL84 PP ?


Speakers: 92db singledriver, 7 Ohm average, 4 Ohm at 60Hz

Question: Will the single ended designs (EL34 or KT150) be as stable with demanding complex music as a push pull EL84 amp?

Looking for: Ultrastable timing, high resolution, presence, openness

Possible 10 Watt amps: LEBEN CS300XS (EL84PP), Coincident Dynamo 34SE, Dennis Had inspire KT150, ifi retro STEREO 50 (EL84PP), valvet E1r (SS)

The Music Reference amps are superb. I've owned both the RM-10 (EL84) and RM-10. So, second Bdp24, good choice. Most of the speakers they drove were 87-89db, 4ohm. Best, Rob
