Our room was so busy that I don't know how many people even knew about your new amp, it was next to the Lina and hooked up to it, I tried to explain to as many people as possible what was going on. A few people have emailed with very positive remarks, I thought it sounded incredible. Based on these El3n comments I will have to compare shortly, admittedly I haven't even heard Caldera off it yet!
We went over what we need to do better next show, and we are going to have a one sheet that explains the setups at our next show, because with the crowd we weren't able to do that at all. A lot of people heard Caldera on OTL amps and we weren't able to catch it, part of the reason there's an inconsistency in response, and because of what @HiFiHawaii808 stated, it does seem to change a lot based on what they're fed.
No worries dude! That room was packed, speaks to the excitement around ZMFs new offerings I'm sure some feedback will come out of the woodwork at some point.
