If you are looking for a very simple high end unit with a simple plug and play unit. This mission X-Space hifi set is as simple as you can plug your favorite device on one input and this unit got you covered ! No need for any other extra units that can equalize or adjust your sound. Unit comes with volume control in the middle. Take my words for it once you are plugged you will be completely surprised of how this this unit sounds. I was blown away how this unit can get you the best sound. Super clear, warm and more very detailed ! Unit has been tested and fully operational. I have taken out the grill of the speakers to show that they speakers cones are in excellent condition and that red strips are double sided tapes to put the grill back intact. All pictures are original of this lot and part of description so what you see is what you get !
