Hi Yetis

There is no problem in shutting down the MD600 between listening sessions. HermanAtHome who is using this method has been doing so for a long time. He also used this method when using TwinStore. No failed disks, no problems what so ever. I do also trust HermanAtHome on this judgement when he has been working in the computer branch for around 35 years and has a great deal of experience of computer systems operating 24/7/365.

I let my TwinStores run 24/7 but that's because I want my Sooloos to be ready whenever I feel for music.

Best Regards, Per Nilsson, Sweden
