Bose 901 Review Well Done.

@hersch8888 : Spotify is lossy audio. Try instead Tidal or Qobuz.

If you are already an Amazon Prime customer, Amazon unlimited is a good bargain and has a very good selection of hi-rez. Up to 24/192. 

I don't like Hi rez audio...but thank you for the rec!

I've tried it...I find d it's "cut.and paste audio"

It's akin to TV these days where you get that "Soap Opera " effect video.

Like hi rez audio " it.doesnt jam" does not exude the right emotion...

Just like you can't replace an old song on.an old AM radio...

Hi rez is just numbers to my ears.

Cheers!

And the soap opera is the first thing I adjust on my new tv's.

Smoothing Motion plus Video....OFF!

We used a pair for the PA for a short time.

In hindsight the state of the solid state power to drive them with any authority in 1970 had their own growing pains. 
It might be interesting to hear them driven by todays refined solid state or hybrid amplification.
