Hi Sili and welcome to the community forum, I hope you enjoy your time here.
Only you can know exactly what it is that makes you like the Goldmund piece so much. It clearly has benefits that are important to you. That being so I cannot tell if it:
Those are matters that are personal to you and also relate to the other components that you have in your system.
However you are probably aware that dCS equipment enjoys the highest reputation. I might suggest that you familiarise yourself with the company and why it is rather different to many other DAC makers (and do click on those " learn More" options) :
As this is such a personal thing you can really only find out if it is for you by going to a dCS dealer and requesting a demonstration.
One thing that I can tell you is that the Network Bridge is no longer made. So Bartok or Rossini is your choice for new pieces. dCS ensure that each step up their product line produces clearly audible benefits. So, if you have the finances, the choice is easy; Rossini or even better Rossini plus Rossini clock ( many find the two inseparable).
One other thing I can talk about is your HD music files. The Goldmund is very limited in this respect as many higher resolution formats have emerged since its introduction. Bartok/Rossini are far better equipped though even in their cases even newer formats have come along. However many of these are unicorn formats or otherwise have very little support in terms of available software. I guess there may be a game of technical leapfrog continuing for some time or, even, for ever!
Let us know how you get on.
