I was "almost a customer" for Aegir 1, but could never quite get there. Even at the current closeout discount, I was still not a customer for Aegir 1. Based on the Output Impedance nugget
@Jason Stoddard shared in the video, I am absolutely buying Aegir 2. In my mind, they are not the same amp... but I haven't heard it. I do not think this is a "small iteration"...but I don't "know". I'm not even referring to the bump in power. I expect, for my preferences, the Aegir 2 will be notably better - for me. For what I have come to like, it is the obvious choice. The taste test will start with 1. If it tastes like I think it will, I will absolutely order the second unit.
I have made plenty of noise about my gear preference, why it's a preference, etc. My current amp is several multiples in cost, even in comparison to dual Aegir 2. I am hopeful Aegir 2 will stand on its own against a 5 figure (retail) amplifier that I really, really like.
This stuff is fun - especially if you know what you like and have an idea the things that matter for what you like. If you have't tasted this stuff before, the Aegir 1 might be a good idea. If you decide it's not for you, you can get out of it without much of a hit.
