Allen, the only thing you will lose out on if you were to go with say, that DacMagic and an integrated of some kind, is the dac in the Decco. Those dacs that are inside that amp are supposedly worth the price of the entire amp alone, at retail. Not to mention the sound of the dac is outstanding and you'll save on interconnects.
I would just say get the Decco and then when you are comfortable enough with its sound characteristics and you know that amp inside and out and what kind of options you have with it, then you can easily go out and start picking up other amps and try customizing the sound. You may find you like the Decco as it is.
But since you really are starting out, I'd certainly keep it simple. And it'll give you a nice starting reference point with which to grow. Either way, in due time you'll start expanding on it and you might not appreciate spending $4-7K on a starting stereo when you could have had the sound you wanted for $2K.
Regards
