Would I hear a significant difference at this price point?
Aged and untrained ears are not going to hear significant differences.
But, the slightest difference can become quite significant for someone over time and dominate their psyche (most audiophiles might fall in that category).
If your budget is restricted to 1500, the Gustard R26 (the R2R version) is an incredible dac that often goes on sale for right under 1500 dollars...You could rip all your CDs, put them on a NAS and it will stream those files from your NAS, without the need for some extra streamer and cable botching things. Most stand alone dacs won’t offer you that capability..... Err...awful name though i know (rhymes with some bastard munching on custard), but if you can get past the brand name, it’s a good dac.
