Why not sell the X-1 and buy the INT150 which has an amp section based on the X150.5 and a pre amp section based on the new XP-10? Contact mark at RENO HiFi. One box and the sound should be superior. I have not heard it, but I did have the X-1 and now have an XP pre amp. I believe the X.5 amps are more refined than the X amps.
