I think you need to define what better means. I may think something is better, but you may hate it. Also, you don't list an amp. It would be helpful to know what it is.

I'm assuming that your goal is to get better 2 channel sound for music. If that's the case, the SSP 800 is most likely a bottleneck. At the very least, you should try to bypass it and listen using equipment you already have. I'm not too familiar with the Olive, but if it has a volume control of its own, plug it directly into your amp. If you can do this, I think its an experiment you'll find well worth your time.

Neither Spotify nor Amazon offer good quality streaming sound, with low bit rates...
