Nice equipment. Well, the amp and preamp.
Ok. If you are like most of us, then you sit and enjoy listening to music. To do that you set up your speakers 6 - 8’ apart and position your listening position to make an equilateral triangle. Then with lots of small adjustments the whole soundstage snaps into place. The triangle can be bigger with really huge speakers and powerful equipment… the exact opposite of what you have. You have some of the most coveted warm - natural sounding equipment on the planet. So, much discussion on the setup needs to take place. Photos would be really useful… there is a place under your userID to create a virtual system.
Next, the BlueSound is outclassed by orders of magnitude by your main system. It’s like you are using a transistor radio to feed it. Your system deserves at least an Aurender N20 or better with a high end DAC… I am a big fan of Audio Research DAC 9 for it’s warm natural sound that would complement your main system.
