I think what Morph201 is saying is that there are several features that the Opera has that may be unnecessary for some buyers. For example, the Opera has a DAC, but some of us have our own stand-alone DACs or have sources with good-quality DACs already included. Similarly, the pre-amp out would be unnecessary for someone who already has a high-quality pre-amp or integrated amp. Likewise, having two headphone jacks would be overkill for someone who only listens to one type of headphone; the other jack just wouldn't get used. However, the buyer is still charged for these things, even if he won't ever use them. It would be like living in Siberia, but buying a car that has air-conditioning as standard equipment.
That being said, you can still consider the Opera to be worth the money if the features that you do use are worth the cost. So even though the Opera has several features you might not use, the headphone amp section by itself can be good enough that it's worth the price. At the same time, though, if all you were looking for was a great headphone amp, without a pre-out or DAC or multiple inputs, you kind of wish a stripped-down version was available so you could get only the features that you want, without having to pay as much to do so.
