I had a Statement 861 from GNSC. Before the upgrade, I listened to many players in many systems. As my ears and taste improved, I began to find the 861 lacking for all the reasons you may read about in these disussions.
I decided to not give up on the 861 and ponied up for the mod. The mod, for me, made the player everything I thought a real high end player should be. I found that I did not need a preamp. I also found that using a preamp less than $6-8k retail after the upgrade was a waste.
If I thought that I was getting a thin sound I would first try warmer ic's like Caras or Wireworld (copper), or perhaps get a tube preamp or amps. The 861 can truly make music. It does require some tweaking though. Good listening!
