why a 75 dollar blue ray smokes all 2k CD players and any turntable???

I have more than a dozen recordings, originally done before digital mastering, on both vinyl and digital.  While there are real differences between them, I find neither to be superior.  There are things I like about each that are better than the other, and none of them surpass the sheer enjoyment of the music itself.

I still have the first LP I ever bought, while in high school back in 1968.  I have many LPs that will never make it to digital.  But for newbies, vinyl is just not cost effective.

I run a $200 Tascam CD player with an optical link to a good DAC.  Digital data is reliably transported.  That's why we like it.   The difference is all in the DAC.   All CD and DVD players have one built-in, but they are typically pretty cheap.  They sound OK, but taking a direct digital feed from a cheap player to a good DAC will give you very happy results.

Russbutton:  Exactly.

Years ago I had a Pioneer blue ray player which was supposed to be good. The picture was good but when I hooked it up yo my audio system, it sounded terrible.

Back in 80s, I sold technics, JVC, and panasonic CD's.  At the time, they all sounded the same. They were all priced the same. I held off purchasing one to the late 80s. This was around the time, I first heard what HiFi really sounded like - It was a tube Telefunken system imported from Germany. It was unlike anything I had ever heard in the Stereo shop. A warm lush wide soundstage that immersed around my ears. It was magical. I began my CD quest and bought a Philips CD-880. Many told me I was insane for paying $1000+ for a CD player as they all sounded the same. I never heard it before buying it.  Well many can tell you, it does not sound like the cheap $300 CD players of that era. It is a natural sound with clarity. I kept it for 20 years and sold it when the Denon SACD/DVD entered my mix.  Yes 5.1 audio like DTS sounded amazing and was cool but like most things, it was a fad.  A couple of years later, I really missed that Philipps & bought a used one.   

I am a bit confused why this is being discussed at length. Are speakers the weakest link (theoretically) in the chain. Uh, yes. Does that mean that nothing else matters? Only to someone with a tin ear. If they are happy, I am good with them. But why the hell would they be on Audiogon? There is some equipment that I personally like that is barely "good enough" to be on Audiogon (not my opinion; I have looked for it here and it ain't around much - and not because people buy it and keep it forever.) So why the long thread? It started on a total BS premise. Everything matters, but speakers are the final and weakest link.
