I use oratory's HD650 preset (with the 105 low shelf filter at 4dB instead of 5, only change I've made so far) and the pre-amp wants -9.3dB. I have an Aune X7s and at medium gain I don't have enough on the volume knob depending on the track. High gain is quite high at 20dB on that amp. The Topping E30 v1 with 2Vrms feeding it has the same issue at the highest gain. That's the amp I'm ultimately looking to replace in the office.
I feel like the L50 will probably be enough, but I'd rather it be "more than enough" and feel like, perhaps, the L30 II might be the way to go. Using balanced with the Aune ups the power significantly, but either that on medium gain or single-ended on high gain definitely introduces some distortion before very high levels. This is why I'm hoping the L50 or L30 II will solve that issue. The E30 v1 is in the living room right now for the times I play games through my PC out there or the very occasional music listening I do out there with headphones instead of the office. No EQ out there so it's barely enough for my needs at high gain.
