Yes, I saw this post the first time you referenced it.
If your concern is why did I have an issue with an early Puron? I spent seven months experimenting with these devices. At that early stage adding another to a specific location improved clarity and focus but was detrimental in soundstage center fill. There were reasons unrelated to the Puron device that I experienced that result.
If your concerned about the discontinuation of the HF MC 0.5's, that would be because while finding them beneficial they also had a affect that I found somewhat unnatural. After a while I found a better option and stopped using the MC 0.5.
I visit this forum to acquire audio knowledge, receive some entertainment, and share the experiences I believe might be helpful to other members of like mindedness.
I find this exchange neither beneficial or entertaining.
I notice that the vast majority of your posts are negative and confrontational.
I see no reason to continue this particular exchange, but congratulations on your one-week membership...you're off to a great start.
