I had Concept 20 high-level paired with 2 REL T/Zero's which was quite good setup.
I had a long thought where do I want to land with my sound desire.
I knew that most likely I'll stay on streaming and flac's from NAS, no CD or turntable.
So NAD 758 with Dirac, BluOS, NAD amp and weak link were my speakers.
Decided for 500's as for the price dealer asked, they seamed to be best value I could get from them. I read a lot about them, they were called NEUTRAL which is what I was looking. I'm not very experienced here to give some PRO valuation in English.
They do impress me with the soundstage, clarity and instrument separation. When I listen to music and I know, the avr IS in stereo mode, still I have raised countless time to check is my center is off?
Sound comes on me as wall, speakers are not present! I know, that some people, to better enjoy their sound, close their eyes. I don't have to, even when I look directly to speaker my brain don't locate it in the wall of sound.
