Hi Simon, Thanks for the kind words. I actually ended up purchasing Joey_V's SR Tungsten ICs. With my V2 modified SR MPC on them they are simply outstanding. You might be interested to know that I have recently been experimenting with a different main power supply cap that has much more lower mid range and bass power and heft. A few of my other customers have commented to me, and on the Agon forum thread that with this new cap installed they really can't hear any difference between it and their Transporter when used on their Power Cells and Tranquility Bases.
