No problem. If UiiSii is as good as people report then the thread should hold it's own. When I see how many models UiiSii has released over the past two years I reckon they are KZ's closest competition when I consider a company's ability to keep up with strong demand without be strangled by the lack of working capital. If the company is managed properly they should be able to increase their market share and compete with KZ, otherwise there will continue to be a one-hit-wonder every six months and KZ will go practically unchallenged. Maybe they're happy to be where they are but hopefully, UiiSii will rise to the occasion and bring more exceptional models to the marketplace. I purchased the US90 about two years ago and the Hi-905 about six months ago. The US90 was comparable to KZ's price-to-performance ratios, but the Hi-905 was questionable at $50. Going from memory the US90 was comparable to the ED3 "Acme", but I remember the "Acme having better noise isolation. I'd love to see UiiSii take another crack at it by competing against the ZSR, especially if they can do it with a single graphene dynamic driver. At any rate, if CM5 owners are enthusiastic enough then the thread should be off to a great start as the impressions and reports come in, but if the CM5 is a one-hit-wonder the thread will probably stall and die. Time is either an enemy or a friend so keep a watchful eye.
