Any feedback on the Levinson no.390s upgrade ??

I called to upgrade my #39 and is $1,800 from the factory and $2,300 with a new face plate. A much higher sample rate and more 3-d type sound, better highs and lows. You can read about it on the WEB site. I have been waiting for a local store to get one in and check it out before I upgrade. From what I read it is a major improvement.

A clarification, I was told by Madrigal the cost to upgrade the 39 to the 390s was $1,800 from the factory with full check out of the player. If you want your local dealer to do the upgrade it is $1,500.
