I spoke with CJ about upgrading - the have not put a price on it yet. It will require a virtual complete overhaul, new PCB board and power supply.
The retail price has increase from $13000 to $16000 for the series 2. So it seems anything under $5000 would be worth it.
As a short term fix. I have upgraded the tubes to NOS DRs and most important treated the tube pins and RCAs with Xtreme Quick SilverGOLD. The change was dramatic, a big improvment in dynamics. In fact, I almost jumped out of my chair on the first listen. I would also replace the stock PC, I've had alot of luck with the Nordost Valhalla PC coupled with the Thor conditioner - this also increased the dynamics , improved the musicality, and widened and deepened the soundstage.
