Thanks. I will try to contact him again when his server is back.
I sent him a text on his cell phone number listed on eBay to see what's wrong. It appears his email and website hosting service are upgrading their servers. Apparently the poor chap can't even list anything on eBay or view any order enquiries till they are finished.
Good news is that his new toslink cable design will be ready for shipping this month. The 4mm ones he supplies are not bad, but a bit thin for my liking. I have always had better jitter test results with 7mm or higher. I look forward to trying out the new ones, which are 7mm thick apparently.
