Jm2c but to me step up is definitely worth it.
I will say that the 760 doesn't seem to go as loud as the 6s.mkii. Is it just me?
UHA-6SMKII and UHA760 has the same amplifier design and similar power output. The 3 way gain and supposedly channel imbalance at low volume advantage on 760 is useless because you can have the 6SMKII modified from the default gain of 0dB for low and 18dB for high to -12dB and 12dB.
UHA760's 3-gain level is -12dB, 0dB and 12dB. Do you get the correlation? It means if you modify the 6SMKII you are actually getting the 760 at a lower price (Mod is free, just ask Nick). At -12dB gain for sensitive iems you get wider range for the volume control and need not worry of channel imbalance at low volume. The pot is good from 9 o'clock up.
If you use full size cans you would most likely need the full 12dB headroom so the middle gain setting is 760 is utterly useless for most cases.
At their default gain settings, the 6S can actually drive headphones twice the volume compared to 760 (6dB difference). You already observed this difference I see.
The price, the lack of input options makes the 6SMKII the better choice.Not to mention the ability to roll opamps. I'm actually planning to get anothe 6SMKII with the modified gain settings which I intend to use exclusively for my ciems.
