Having quality and high performing products as our offerings are always part of our mission. As part of our value-adding practice, we are providing modification upgrades to components in both internals and exteriors of products to push their performances even higher.

Stock components can never make it in this perfection-chasing hobby/past time/profession, whatever you called it. Mass production of components and parts for OEM / Manufacturers allow them to fabricate equipment and gears at large volume, resulting in the possibility of bringing the cost down even further. While we can be assured of the quality control of these products (most of the time), their capabilities could only be maxed at that level without paying for a premium to achieve the next step of performance. By tuning specific parts of these product and upgrade them to an elevated quality of components, we can level them up rather significantly.

These components we are talking about can range from simple drop-in upgrades like opamps replacement, to a whole change of the internals in the form of material wirings, capacitors re-capping and upscaled component substitutions/additions.  

For QA, there is no snake oil or placebo on these deemed ‘insignificant’ upgrades some doubters are having; we have done enough experiments to be sure that, say, different capacitors DO sound differently, to as much as a 25-45% positive change in sound. This percentage change is almost akin to a substantial upgrade to higher end series of tubes or opamps.

Similarly, there are no change for the sake of changing as well – in fact QA is beginning to appreciate the philosophy of less is more in such path of electrical and signal transmission, if we are allowed to be in the purist camp. A smaller and leaner product with less transistors soldered on does not mean it is any less good. Our Amanero-Referenced 32Bit 384kHz DSD256 ES9038Q2M Portable DAC / Headphone Amp and TPA3116 amps are perfect examples of our faith placed in these portable designs that can actually perform to some customers’ appreciation and stood up to their satisfaction in the amount of value paid.

With our components modification upgrades, not only will customers be assured of meaningful improvements over stock products, they can also be assured our products will be uniquely-QA, fully packaged functioning in a set to the interest of our customers – instead of some lazy reselling of products one could buy anywhere online nowadays, and also possibly requiring the need to gather a few purchases to get it work.
