Some more listening in, and some more clarity around things. It really takes a LOT of time and a lot of listening to get a good read on these amps. Doing 4 amps at once is brutally tough. It just takes lots of quiet, relaxing, restful listening time to get a feel for each of them. I totally get why AB testing doesn't work if you don't have a lot of experience doing it. Ideally, I'd want a couple of months for this. Really!
An easy trap to get sucked into is picking music that supports the strength of one amp over another. It can trick you into preferring one over another, but only on certain types of music. But they do that music so incredibly well, that you start, or at least I start, to pick music just to hear how awesome it sounds. Problem is, in the long run, I won't only want to listen to the music that sounds great through that amp. I want to listen to the music I love. And am amp that funnels your music choices to accommodate it, rather than accommodating your love of any kind if music is a little to specialized for me. Or perhaps, my music is too eclectic for it.
So, what does this mean in terms of the amps being tested? It means I will give the Exposure a bump to a solid second place. It really is an amazingly solid all arounder. Plus, and most importantly, it is tons of fun to listen to. This amp really knows how to cut loose and rock. And while detailed, it is still very forgiving of recordings that aren't the best in quality.
The LFD? Still first, but with a caveat. As I stated , it does mids like a good tube amp. If your tastes run to vocals, jazz, blues, etc. this amp is a killer. However, it's just a little too polite to really rock. You'd feel a little silly playing the Sex Pistols through it, for instance.
