Have you reached your end point with this addictive hobby?

I done. I have said that about as many times as I said I was quitting smoking cigarettes.  I did quit cigarettes a couple of decades ago.  Much easy to quit smoking than to stop upgrading stereo equipment. 

we, Americans are unhappy, angry, bitter; buying expensive stuff is how we cope. There is no satisfaction just filling voids, when we realize it didn't fix it but maybe the next one will, the bigger more expensive purchase will be the last one, or so we hope. 

I am absolutely finished after I install the new speaker cables I ordered last week.
 

Although they may expose a weakness in my standard power cables.  So definitely after I evaluate new power cables. Of course, plugging in new power cables into a standard wall outlet seems silly.  Hmm, I really need a way to listen to my old SACDs.  I see Innuos has released new high end streamers.  Wait, what was the question?

It appears that it's not only Americans that are that, it's like a wave going around the globe.

As for sort of therapy, audio equipment and other purchases, there is no doubt about that. Effective or not, it varies, I guess.

I am finished once I: complete my audio room, get the room treatments done, buy another pair of speakers, upgrade my DAC, get a new streamer, and finish about 30 DIY cables I bought bulk cable and connectors for. So nowhere near done
