You may already have interconnects and power cords identified for the ModWright 999ES which you may be ordering. However, if you are still considering these items, I strongly recommend the Revelation Audio Lab PRECEPT II pure cryo silver source cable furutech for the Sony player pc and Revelation Audio Cryo Silver Paradise interconnects. Dan carries both.
I purchased a 999ES Platinum mod at the end of October and am very happy that I took Dan's advice to use both with the 999ES. To my ears, there appears to be a definite and positive synergy when I use these interconnects and pc (on the player). I am using a VH Audio Flavor 4 (Furo) on the tube power supply. My other interconnects and speaker wire are Cardas.
P.S. I also added a VH Audio Flavor 4 (Furo) pc on my preamp. In my system, this combination definitely kicks it up a notch (over the stock pc with Versa Labs Wood Block). Interestingly, when I move the Revelation Audio pc to the preamp and the VH Audio Flavor 4 to the 999ES player, the "magic" subsides. It still sounds very good but not at the pristine level it is with the Revelation Audio pc on the 999ES. The Revelation Audio appears to be a match made in heaven when used with the 999ES. Raphael
