Equipment that has made you 'stop' looking?


OK we all know what a merry-go-round audio can be. For those of us who are incessant upgraders, what components have you found that either have stopped or seriously curtailed your search for better?

For me its my Audio Tekne Cables and my vintage Classe DR3 amps (25 wpc high current class A design designed by Dave Reisch in the early days of the company). My Green Mountain Audio Continuum 3s would probably fall into this category, but I would probably buy the next statement models that Roy Johnson builds sight unheard.

With all due respect, the only component that can make you stop looking is the one between your ears. 
I think I'm "done" for now, though I might upgrade my disk transport to the new one from PS Audio in the future:

My system, with all digital sources, has a P15 power regenerator, DirectStream CD/SACD disk transport & DirectStream DAC from PS Audio, a Roon Nucleus Plus streaming server controlled from my iPad & Android smart phone, a Dell Windows10 Pro machine for iTunes, McIntosh C2500 tube pre-amp, McIntosh MC452 solid state power amp, driving a pair of Focal Sopra No2 speakers, and a pair of JL Audio F113V2 sub woofers, all connections with Wireworld cabling.
