Replace HDD in Sony HAP Z1ES with an SSD

I had to speak to a colleague who's an engineer (I teach Liberal Arts, meaning I'm clueless). He said firmware likely limits the amount of real estate the HAP Z1ES will recognize - though that is a generality, not specific to any particular app. He also mentioned that a NAS (RAID 6/4 disks) can be connected via USB. I have done this, and I can hear no degradation of performance through Audible Illusions m3a Pre/MC 275 VI monoblock/Harbeth 40.1/REL Britannia.
That makes capacity a non-issue - 4 3tb disks in RAID 6 yields 9+ TBs, or about 10,000 cds. If you have more than that, please invite. I'll bring Macallan 18!

ott,

Thanks. I am as clueless as you so I thought I would ask. Especially because my car instructions say it takes only up to 128GB SD card and I am using 512 with no problem. I do not have 10000 CDs, though. However, I may multiply them on a hard drive to apply for that Macallan 18.

Just say the word.. 

Or Lagavulin 16? So much scotch, so little time.
