Hi there. I'm quite a noob in all that audio stuff, so sorry in advance for my silly by local standarts questions. Being interested in buying AE-9, first of all I'm curious about one thing... For example, I'm planning to use it with that external module with headphones connected to it. And it makes a question, is this module connected with those replaceable op-amps, or - op-amps are connected only with rear audio outputs on sound card? Because, I'm afraid, that if I'll decide to replace all those op-amps with some more expensive ones - I'll hear the same sound in my headphones, because op-amps suddenly doesn't affect the sound in external module.
Also, curious about all this Dolby stuff in a sound card. Dolby can be used only with optically connected audio receiver? Or, I can also use some kind of DTS Headphone:X, or any other Dolby stuff in my headphones through the external module?
