Though I haven't heard the 009 as of yet but with the majority of other can's. I don't think I will be satisfied with just the 009 alone given the general description of there sound from people I trust as I listen to a wide variety of genres and subgenres of that genre etc. The 009 may be great to alot of people with reference based genres (classical, jazz etc) but for other people such as bassheads or people who stick to only CIEM's etc, they won't like it, it's the same for example some people that I know that owned the 009 for a little while and then went back to there LCD2/3, Hifimans etc.
That said if you have a lot of money to throw around, why not invest in separate standalone rigs featuring all the flagships from every well known manufacturer? It becomes pretty fun, something I'm doing now but the problem is I'm out of money.
