Levinson 360S

Hi! Anybody out there have any experience on the Levinson NO.360s & NO.36 DAC? Is there any sonics diferrence between two of them? How much it going to cost for upgrading a 36 to 360s? Is it worth to do so. I appreciate for any of your opinion. Thanks
I am selling my ML#36 for S$3000. I am in Singapore and I can be reached at 9791-2898. My name is Lenny. It is a worthwhile upgrade from the 36 to 360s, and it costs S$5000. The nice thing is that you can upgrade anytime you want (wait for the 24/192, DSD/SACD version to become available?)
I have a 36s at 3000.00 if interested.
