Thanks for impressions. I have a question, how is implemented insight StageDAC master clock and the power supplies. This is very important topic which determines several aspects of the sound quality, especially jitters, noise or brum. I know that Maier products are good, well optimal for Premium (classical high end) headphones like HD 600, HD 650, K 701, DT 880, D-2000 etc. I listen this DAC once for (at about 10-15) minutes. Naturally I am open for cooperation and comparing with devices which I know, with Bechmark DAC, Cepheus DAC, or Sirius module etc. But naturally, do not expect from 150 dollars solution more as it is insight device etc.
About crossfeed, by the principle true analogue form is always better then digital one. So if you compare the special circuit implemented in ZAMA HPA-1 amp (Mr. Vrana is interested to implement it to Lyra amps too) and any digital solutions then the analogue from success. The problem with bass is caused by the quality of algorithm implemented insight (or used approach). Binaural processing is not only crossfeed but the correction too. And naturally, the sampling aspect as I wrote once.
And same is true about „active balanced“ things. True balanced connection is totally independent in paths, the components are installed discretely, amplification items are 2x more then in SE form (see for ex. GS-1 and GS-X amp), etc. A lot of producers apply the trick that they „insert“ something from the world of „balanced connection“ but the main construction of the amp is single ended. Serious benefits are naturally lost. Again, when you see serious typical balanced amp and these devices you directly recognize the things. In this case, perfectly produced (tuned) SE amp delivers more then speculative pseudo-balanced devices. This is my experience. Naturally, I am open to compare new devices with one which I perfectly know.
The aspect about global business approaches in the area of audio devices I clearly presented. I presented general phenomena came from business analytics. The performance to price ratio was rarely visited in details in past, but today it is more and more lighted. The world is changed and naturally new approaches need be applied. The simple „comparing“ by price is not so successful because you need understand technical things applied insight. Here is often used approach that there are used some high quality components (for presentation how this device is so excellent) and several chip components so people say it is phantastic quality but the situation is different. But when you take true device where things are right, optimally chosen all things, and when there is rational (good) parformance to price ratio, then naturally you very clearly recognize how things are. This is typical for CD or SACD players, but the same phenomena are found in DAC’s implemented in amps. But naturally, here are several exceptions of brands who does things well.
