Why I sold my $50,000 DAC ...

I’m not a measurement snob by any means but I would surmise a 300k dac is in some ways pretty “colored”. At 300k it better sound different.

Can you recall how many output channels were in use?

The reason I ask that was a bee in my bonnet that says the easiest way to improve sound reproduction is to add more channels.

It was not long after stereo (2-channel) LPs were introduced that 4-channel records came out.  Then SACD added 3 or 4 channels to CD's 2 channel, and Blu-ray Audio extends that to seven channels of high resolution PCM.  Later formats like Dolby Atmos extend the number of virtual channels to 32.

I have a lumin x1, it's a streamer dac. I think it's phenomenal. I have bought separate dacs and I hate having to get all the interconnects and then deciding on changing it out trying something new. Frankly I think streamers and dacs should be internally connected. Done well it's great.

Great speakers and great amplification. 

Not sure about spending a lot of money for a room.  Then again I don't get out very much so I haven't heard many rooms.  

Room acoustics is key as all have said above. Unfortunate I realized that later in the journey. no problem, I finally did what I must do.

Room acoustics is key

I think this is not as important for speakers which present as single point sources, or single line sources.

The ear-brain system sorts out the simple reflections from coherent speakers, but has problems with the multiple reflections from the multiple, spaced drivers found in most dynamic speakers.
