Interesting stuff.... I know others on here who didn't find such a leap from Tellurium Black to LS25 but would to LS40. Could well be system dependent. I'd be surprised if the leap to LS40 isn't more revealing than the improvement you've heard already. Get your wallet ready.........
interesting! Yes it could be system dependent. The Ls25 compared with the Black 2 sounds like a veil has been lifted (cliche I know) and so much more of everything.
