I'm married to Aerial 10T since 2003 and never upgraded them and that's so far almost 15 years . I heard about Andra speakers and would not doubt that they may have that kind of potential to be placed for good and it's good, because changing speakers is most expensive and painful upgrade. After having my Kef Ref2 speakers pushed by my toddler to fall, I decided to get large footprint heavy speakers and absolutely spontaneously found used 10Ts with blown woofer for $1200 off craigslist. After replacing a woofer and playing few familiar tunes, I realized that those are my final speakers. There's no way toddler can push them to fall!
