My salesperson at TMR contacted EMM Labs about whether I can upgrade the Meitner MA3. He said that the people at EMM Labs were very friendly and I can contact them myself, without an intermediary, about upgraading to MA3i. So, I'll see how things on the homefront go, but maybe in a year or so, based on what the MA3 owners have said on this thread and elsewhere about how the improvement is worth it.
But I do want to say one thing. When I was maybe 7 years old, in the mid-fifties, Annie Oakley was a series on TV. I have read some of the greatest poetry known to man. I studied poetry and I have written it. One of the most memorable lines, however, was when Annie Oakley told her younger brother, "No matter how fast you are there will always be someone faster." No matter how good we've made our systems, there will always be better systems and better pieces of equipment. At some point you just have to lean back and "love the one you're with."
