I find questions about perceived sound quality really interesting to explore. In the case of direct sampling into the OT, one becomes an engineer, with all the attendant issues of the engineer. What are the techniques for capturing pristine, beautiful audio? There are many dimensions and layers of solution to that task. There is deep craft involved in tracking, monitoring, mixing, and mastering. Many of us wrestle with perfecting these processes, and the difficultly level of the learning curve is painfully exponential.
One could spend the equivalent of two OT’s on a single mono channel strip. And then, are the contacts plated with gold? Will that make the difference, finally?
It reminds me of issues I often read about in mixing forums: why doesn’t my music sound like I want it to? The degree of confusion is notable. A parallel might be an athlete wondering why he doesn’t just shoot like Jordan. After all, he’s wearing the shoes?
Anyway, I think the OT sounds pretty good, overall. It’s an interesting instrument and leads the user down strange lanes. I suggest one keep searching, like an intrepid explorer, for the elusive, fabled sounds you want to create. They are out there somewhere.
