My first Aro (last year) was also a Qian Hu 'Premium High Crossback Gold' (but from Singapore, not Malaysia). RIP, she jumped into a corner filter while I was away on business.
So the name isn't really new, like Galantspeedz says it's a marketing name for their Xbacks (of which they have several levels/pricing -- I think their best Goldens are called 'Supreme' or something like that -- I saw one super gorgeous, fully crossed juvenile for sale at Chatuchak for a whopping 85,000 Thb!).
But my feeling is that Qian Hu is one of Singapore's best and most established Aro farms, and you generally get good value for what you're getting (and get what you pay for).
My Premium was quite beautiful and very shiny, but not as crossed over as the 2nd Aro (Goldenhead) I got from a Malaysian farm (which cost about 30,000 Thb compared to about 18,000 Thb for the Qian Hu Premium.
And yes, not all Xbacks fully cross over the top (6th level scales) -- with my Qian Hu Premium I'd say it would have had a good chance to be mostly crossed over but not sure if fully and I doubt its head would have become too much more golden. But still a beautiful, quality fish for the money.
