If you judge a product based on price, I have industry inside stories to tell you.
If you are saying that an expensive high end CDT can out performs CDT-8 Pro, of course it can. Our own CDT-10 cost a lot more and we found ways to do better, as you have stated, in power supply circuit, mechanical isolation, noise reduction etc as listed on CDT-10 product page.
There is one big difference between NuPrime and some other brands - we don't pay OEM to build the products for us. We owned the OEM business. We have our own factory in Taiwan. So we are able to offer better value for the money.
