Cool description! May I suggest to publish a 2nd part recording the same source for a couple of seconds, so they can be better compared by potential customers? Three years ago I originally intended to get the LCT 640 TS because I heard it in a few guitar gear demos, where it was used together with other classics, and it blew my mind. Since I couldn't really justify the expense I ended up getting the more budget-friendly LCT 440 PURE, and I'm really happy with it, it does everything. However, I still don't know if the very close frequency response chart compared to that of its bigger brother is actually significative in the real world, sound-wise. Hence my request.
