Thanks to all on Computer Audio to help me jump to another level in music reproduction.
I have read a few of the comments here which are based upon a variety of experiences. I'm just someone who did the research on the web and combined with my aerospace engineering, physics, and math background and 3 decades in defense technology R&D (34 yrs performing with symphonies and quartets as a violinist) and what i ended up with starting in 2002 was a 7.1 KEF Q series speakers combined with an Onkyo 705 amplifier (around 2009), plus a lenovo yoga pro i7 laptop (2013) and the Teac ud501 DAC (2015) in a dedicated mini theater - all of this equipment is not even high-end. When taking CD audio and converting it to lossless FLAC and in real-time upsampling via Signalyst HQPlayer (software filters, 2015) to DSD64 (~2.8MHz/1bit) then to analog stereo input to the amplifier, all i can say is the music was Glorious, e.g., Engelbert Humperdinck, Frank Sinatra, Jazz, Classical genres, etc. The entire family including the dog stayed in the room listening to music for 3 hours, the first time ever seeing the family drawn to the music and music a few of us dont listen too at all (me included). I didnt spend years tweaking anything, just ttok my time putting things together since 2001 - in fact i hardly listened to music in the theater, we primarily watch movies (i also have the SACD player Denon ud4010 which i probably only used a dozen times and paid too much for $1799 at the time - sounded really good via 6 analog outputs but too lazy to go get the discs out of folders and play them)! For some reason this new basic chain of technologies (doesnt include the SACD player at all) just blows away anything i have heard before. My only experience that was equivalent to this technology chain (complete 2 weeks ago) was at Goodwins Audio in Waltham, MA in 2004, where they had a pair of Wilson Alexander speakers $150K and played a classical cello piece and jazz CD in a specialized room made of wood panels, diffuser panels, etc., the soundfield was astounding. I dont have any measurement equipment, i dont have time for that, and i dont have an audio engineering degree, but i do know that between the Goodwin Audio room that played CDs and the "technology chain" at my house playing CD upsampled to DSD then to analog out, that they both evoke the same sort of musical involvement in listening that you ask yourself if this sort of music reproduction is even possible and you are hearing it like at a recording studio or being there. The ages for our family ranged from 26yrs to 89yrs and everyone was glued to listening to music from the new "technology chain". You get the feeling from the experience as though you had stolen something, next thing you know, im calling my brother about it, telling my friends, and coworkers and they get this puzzled look, what is SACD, what is DSD, do you mean DAC to be digital analog converter?
