I'll be honest in saying that I haven't heard any of their designs myself,but I think you'll find the various reviews of the Grace rate it very highly indeed,as do many of the posts on
www.head-fi.org which as a US based site can be useful for info on US products....it's also a user oriented site,so you will find feedback from owners there.
The Grace has it's own DAC built in,which may be useful also,in a CD based system.
There are UK outlets for Grace products,and the successor to the 901(not surprisingly the 902) retails for about £1100 over here.
You would need to enquire from Grace Design as to whether these are multivoltage designs,but the website does suggest as much.
