Fully tested in our lab and listening room and includes the remote and the original high quality box with packing materials. 

From a Posi+ive Feedback review, written by John Brazier:

"With the absence of any criticisms, it is not a stretch to assume that I believe the X1 to be near the top of the price/performance ratio. For the money, I do not think you can do better, especially if your preferences are transparency in the sense of wanting the preamp to get out of the way and let the other components do their job. My set-up has been going through a major overhaul over the last couple of years. Circumstances have been such that I have been able to chase the level of performance that I did not think I could ever obtain. The last piece of this puzzle has been the selection of a preamp. With the X1, I did not hear the need to look any further for the "right" unit to fit within my set-up. I now own the X1. Just give it a listen you will be amazed at what you don't hear; you might end up owning one too!"
