Why on earth?

YT music, with or w/out vids, to me is like flipping thru the LPs’/CDs’ @ a b&m shop....

Sometimes with ’something in mind’, but open to the surprise....;)

Using ’phones eliminates my speakers and the space that they and I am in.

As for your speakers for listening to speakers in another space filtered by that to do so....

...I posted a vid featuring my diy efforts a rather long while back (’15)....in G Search as the first image, 7x in the images page....

I apologize for the lousy audio, Sony P&S camera, mono from the mic onboard....noisy fluorescents, ceiling fan on low...at least on a tripod...*G*

....been a low priority to reshoot, and the subject has improved...

Pre-Happy Labor’d Daze...J

@tonywinga RCA did that! They over saturated the colors, loved the irony of those commercials! That's what comes from not teaching people how to, and the merits of thinking critically. Well, that and totalitarianism. 😉

I was a teenager then during those tv commercials and I remember thinking how amazing it would have been if their color tv picture would have shown in color on our b&w tv.  

Listening to YouTube is 100% useless for evaluating the sound of someone's system.  You're hearing mp3 quality over earphones or your desktop rig.  To think that anyone could get an idea of what a system sounds like through that brings to mind very uncharitable words.

End of story.

Differences in tubes over You-Tube?  Must be really really dramatic with linear and non linear distortions in double digits.  Well, some tubes are that bad so OK. 

Going NOS I assume? Ukraine sourced?  Russian or Czeck?
