But you are right. If it's already transparent, you can't make it more
transparent with additional parts
Which kinda sums up the different philosophies between NwAv/Schiit.
The O2 was designed for the highest possible transparency with a certain budget in mind. First he defined what he wanted to achieve, then he tried different designs, parts etc. until he reached the goal.
Schiit on the other hand: "Sure, we could throw an opamp in there and get better numbers, but we aren’t just about the numbers here. We believe different amps sound, well, different, and we made our design decisions based on both measurements and listening tests."
That's okay. What I cannot stand is the "overall feedback is bad", "class a results in superb performance", "fully discrete designs are better" attitude. Not any of these points is an indicator of high fidelity, quite the contrary.
Violectric says: "Discrete amplifiers (designed with transistors) are very popular in High-End audio design also for preamplifier stages. This is often marketed as an optimization measure, but the partially exorbitant extra expenses are of course to be paid by the customer. But an op-amp consists of tranistors as well...
Moreover, its structure has the advantage of thermal coupling between its internal components."
Other than output power, I don't think the Schiit stack would win the numbers game. The question is why they are so fixated on the points mentioned above..
