With the Grace M903 I am enjoying my new found adventures into the world of High Resolution Audio file playback.

Using Decibel from sbooth.org software I am playing back 24 bit files at 192k, 88.2k and 96k

They sound fantastic over my ADAM A3X system but spectacular in my trusty Sennheiser HD580 headphones.

I am gradually collecting classical music and old Rolling Stones albums that I can purchase at these high resolutions.

The volume controls feel great and the separate headphone and speaker volumes are very handy.

This has opened a new world to me.

The unit looks v cool too with its elegant styling.

I am amazed that using one USB port on my 1 year old Macbook Air for a hard drive with all audio files and the other USB port for the Grace works! Brilliant!

PS playback of 1080p HD video YouTube footage sounds v good also
