Next step up on the streaming food chain?

@jasonbourne71 current measurement techniques and equipment do not adequately qualify ALL sonic properties such as soundstage dimensions (just one example). Besides, you are barking up the wrong tree here, almost no one here cares for the measurements crowd blather, the ASR forum is where you should be barking.

@zavato I think your DAC is fine for now, upgrading your streamer is the best 1st step, Lumin Aurender Innuos Antipodes Grimm are all good choices, hard to go wrong, budget around $8-12K to get the best value models, after narrowing your choices it comes down to software differences, if possible audition in your own system.

FWIW I have a Lumin P1 and it was the best upgrade to my system so far in my digital front end journey.

@kairosman @jasonbourne52 Dimensionality and roundness are indeed figments of the listeners imagination, as are all things stereo. But that is neithervthe question or the issue. The question is whether or not they are repeatable and reliable. If they are, then they are true, if unquantifiable. Likewise claims of blacker (a visual term) backgrounds attributable to lower noise are specious at best when the current noise floor is well below the listeners background noise floor to begin with. 'Improved dynamics' is another questionable term because dynamics have in our context a very specific definition: The change in the voltage envelope describing the event. A guitarist plucks a note. The microphone picks up that sound, its 'dynamics' defined by its voltage envelope. Pluck it harder, the voltage envelope increases. Absent an increase in the voltage envelope there is no change in dynamics. Likewise, a DAC whose output variations are greater than the input ('improved dynamics') is demonstrably defective. I'm not saying all equipment sounds identical. I'm saying if it does sound or present differently there are reasons, some quantifiable, some not. But to be valid they must be consistently repeatable.

I owned the G1.1 and G2.1, both excellent units. However, I now use an Aurender A20. In a different league with this gear. 

@jasonbourne71 

indeed - the notion of stereo music reproduction is an illusion, aka, a figment of the imagination. None the less, we try to achieve goals. Those goals may differ person to person. 
 

Let’s just say I prioritize the illusion of roundness and dimensionality
