I can attest that I’ve had 1 Alt 8 that was fat and dark, and 2 that sit nicely. No idea what the difference is or if there was a mislabeled batch or what, but the first Alt 8 I stuck in my CU24 was mad dark, so I exchanged it. Later, I wanted to thicken up my Caparison a little, so I grabbed another Alt 8, and it was way tight and bright haha. Exact opposite of the first one. So I stuck the new Alt 8 in my CU24, and stuck a Custom 5 variant in my Capa. Every thing worked out beautifully. I might stick my modded Alt 8 into my Aries Multiscale now. I was able to get a good sound with the lithiums but I bet I’d like the Alt 8 hybrid better.
