@rudyb I absolutely agree with not quarreling.
You present a reasonable argument why streamers should not make a big difference. I told myself that for years. I streamed with every conceivable device.
Then I finally took home a reasonable mid-level streamer (Auralic Aries G2)… jaw drop, and all that theory went out the window. The problem is, in the real world it is not true.
The streamer is like a turntable in… if you do not have a great source… it doesn’t get any better. Now having owned streamers from the $3K range to over $20K… the streamer is absolutely critical in the playback.
My most expensive component is my Streamer.. to which non-dedicated devices cannot hold a candle… assuming you are being reasonable and not pairing a $200 streamer against a $2,000 carefully optimized PC… or some stacked comparison.
