Why are so many people spending so much money to build “perfect” streaming system?

Right now I'm in a state of audio bliss...listening to an Idagio stream of Mozart's opera "Abduction from the Seraglio." Three dimensional soundstage. Clean & undistorted. Lovely tone. For an eminently fair monthly fee. And yeah, it ain't even Hi-Def.

About a half hour ago I felt the urge to hear Beethoven's Second Symphony.  True, I have a handful of performances on my LP and CD shelves, but I decided to try a performance I've never heard before.  I went to Idagio and impulsively cued up a performance by the .Staatskapelle Dresden conducted Herbert Blomstedt.  Not quite as fine a string tone as I have on a couple of my performances on vinyl, but an enjoyable, well-played, emotionally committed reading. I'm a happy guy.

Let a thousand flowers bloom. And if you're a listener who just likes to listen to your first-day-it-came-out LP of Led Zeppelin II, so be it. I got a "Whole Lotta Love" for ya.

As much as I tout streaming here, I'm not ready to contemplate ditching my other media sources. First off, I just have too much stuff that isn't, and will probably ever be, available on line or over the aether.

Another sticking point is that streaming is dependent on hardware & software that, in my experience, just seems to go bad every so often, often without warning. Every once in a while the laptop I use to  command the streaming festivities just doesn't perform the task, whether it's because it needs a software update or the update I've just downloaded puts my streaming capabilities temporarily out of whack.

Finally, yeah, I do like to gaze at album covers, hold printed opera libretti & lyric sheets in my hands, and gaze at the vintage pictures the liner notes often include. I enjoy reading the technical data, too. Who produced the record? Who was the engineer? Where was it recorded?
