You will have no such problem with Clearaudio. Their customer support at least in the States is first class which I can say from personal experience.
Kiseki Purple Heart vs Clearaudio Stradavari
I am leaning heavily toward purchasing the Clearaudio Innovation Wood/Universal 9 Tonearm, of which I was able to audition with the Clearaudio Stradivari. It sounded wonderful but my heart was set on the Purple Heart which I have not heard, just hear people talk about it with such passion. Not that I don't trust my own ears I just appreciate feedback from the community if anyone has experienced a direct comparison.
