Hi All,
Thank you for your valuable comments. I hadn't actually thought of just adding an MC200 as a storage location.

As it stands I've done it even simpler. I bought a 1TB WD NAS SSD and made a clone of the harddrive with a two-bay hard drive dock; this took about 2 hours. A knowledgeable friend helped me extend the music data partition using a laptop running Unix and GParted. In a matter of minutes this was completed, and I have added about 500 GB to my MC200. The docking station cost about EUR50, and the SSD EUR95.

This adds years of ripping CDs and making downloads to my Sooloos system. I can sit on the fence a bit longer before committing to Roon or similar. I love the reliability/simplicity of Sooloos. The docking station allows me to make a backup of the hard disk with less hassle than the backup options from within Sooloos. I've never managed to get the additional backup option working so must always do a full backup which takes time.

As for the future, I will keep an eye on developments in the industry, although I can't imagine ever parting with Sooloos. If an MD600 crosses my path cheaply, I might go for the redundancy. In the meantime I will enjoy listening.

Thanks again, Jan
