I'm sorry but this is a stereotypical attitude whereby Chinese is associated automatically with bad quality.
I remember how skeptical we were about Japanese, and later, Korean products and cars.
The reality is that these guys kicked ass and that Chinese are on the way to do the same.
So at least reserve your judgment till you actually try the product or read what people who own it and other professionals report.
I agree with Biggles, at least with the quality of the Chinese products in the past and present in a lot of different markets.
I have a number of Android tablets, bought off of eBay, that are from China. Both are supposed to be 10-core processor machines with A LOT of storage. It turns out that NONE of the tablets truly offered the storage they claimed. They changed the firmware details to show extra storage but after a trusted app was installed to learn about the ACTUAL storage in the machine, they were much less. The same also applies to one of the tablets that claimed to be a 10-core processor unit. It is, in reality, a quad-core processor unit. Deception and fraud are rampant among many of the Chinese products. Because they are overseas, there is very little recourse.
With regard to the Medeli music products - they, in the past, have offered sub-par sounds and sub-par quality and with little recourse when the product is defective or quits working after a short period of time. Many off-brand or house-brand keyboard products (like the digital pianos and other arrangers that are very low-priced) are simply rebadged Medeli units with another name on them. Consider the Medeli A1000. It is also known as the Fame G2000 and a number of other off-brands or house brands. They are still a Medeli product. Even Kurzweil is using Medeli products in their consumer lineup, but slap their Kurzweil name on them. Alesis is very liberal in their use of Medeli products and are simply slapping their Alesis logo on them.
With regard to the AKX10, it appears as though this model is using previous generation Yamaha technology for the sounds and styles. Some styles are even named the same as the styles found on the Yamaha counterparts. Maybe Medeli have added new features to make the product more appealing and certainly the price is right. Through a bit of research online and by watching people on YouTube who have actually gotten their hands on the AKX10, one can easily hear the character of the product and it is clear that it is from Yamaha products from the past.
With regard to the products from Japan, I have never questioned the quality of a Japanese product. They have always been solid, at least in my experience. I believe that the problem with the Japanese products was that there has always been fierce competition between the US and Japan, and Japan had a habit of advancing some tech (maybe a lot of tech) faster than the US did...
With regard to Korea, they had to get better with their products before they really played a part on the world stage. Hyundai and Kia come to mind. In the 80's the vehicle offerings from Hyundai were garbage. Now, they are one of the leading players in the game. Look at the Genesis models - they are VERY nice.
If China is going to produce any meaningful musical products under the Medeli name (and other music companies that start up), they will need to overcome the stigma they have created for themselves in the past. Maybe they will be a major player in their own brands, but it will take time. I know that a lot of musical products are made in China for other companies, but the other companies have more strict controls for quality and that is why their products still cost more than something from Medeli. I also remember Behringer being the 'bottom of the barrel' type company in their early days with regard to quality, but look at them now...
Some may also argue about AMS Hydrasynth being owned by Medeli. In my research, it is more likely that Medeli are financially backing the AMS line, but the founder of the AMS products was actually from Akai and Arturia. It is a little more complicated than that, but he designed many products from Akai (MPC5000, MPK keyboards) and Arturia (iPad synth apps, the *Brute line, and the BeatStep Pro). He is on LinkedIn somewhere for further examination.
Even with everything I have typed above, I am still open to trying out the AKX10 and see if it really lives up the hype that has been generated for it... maybe it is a winner and something worthy of ownership...
Grace,
