Yes, the Grimm updates are super simple and because they run FPGA, the updates are actually very meaningful. The most recent update took the Grimm to an even more remarkable level. So when you buy it, you’re buying into a company that’s committed to continually improving the product — they’re working on their own software (a Roon alternative) and a DAC as well, which would make it a true one box digital front end.
Yes, it’s both a Roon core and endpoint. Just add DAC.
You need to use as AES cable into the DAC. DH labs makes good inexpensive ones, black cat makes great but more expensive ones.
I believe there are four US dealers last i checked, any should be helpful if there’s nobody in Canada. There’s Doug White in Philly who is an industry legend and super nice guy, there’s Kyomi in Chicago run by a concert pianist and music professor, and there’s Analog Audio which is run by another special dealer. I don’t know anything about the SF dealer. In other words, it says something when some of the best (best in the sense Of experience/knowledge and also customer service) dealers around are carrying this product.
