Is the difference between the two options just the question of whether you go through the receiver between the source and the Quickie? If so, then unless you are using the receiver as a source selector (and it sounds like that is not the case), then I would go directly from your source to the Quickie, if possible.
If you are using your receiver as a source selector, you still don't need to go through the receiver, as long as your sources have multiple outputs. You can run one set of RCAs from each source to your receiver, and a second set of RCAs to the Quickie. Depending on how many sources you have, you may need to add extra inputs to the Quickie and upgrade the source selector switch.
If your sources don't have multiple outputs, and you need to connect the sources to your receiver (e.g., because you ise them with a speaker system) then you will have to go through your receiver.
