Equipment that has made you 'stop' looking?

I recently had my McCormack DNA-225 upgraded to Platinum Edition status by Steve McCormack (SMcAudio.com). Amplification is now one aspect of my system that will remain unchanged for quite some time - literally years. While of small consequence in geologic time, it is of epoch proportions to audiophiles! :-)

Amp: Fully modded Berning ZH270 (tubed)
Interconnect/spkr cables: Stereovox
Power Cords: Electraglide Epiphany

Digital Sources: hmmmmmm - no "final" consensus. Audio Aero Capitiole MK II SE is certainly amongst the better choices (but probably not better than the Rimyo CDP, DCS or EMM Labs separates)

Preamp: also no final consensus

Only 2x in 25 years have I ever stopped looking. Each time I didn't make a change for 5 years. Both systems were based around tube amps. First system I had for 5 yrs was a Mac MC225 amp, Music Reference RM5 mkII pre and ProAc Studio 1 speakers...Second system was a Korneff 6bq5 SE int amp with Klipsch KG3.5 speakers. I got rid of the Korneff for a Custom Conn PP6bg6 triode amp that I had for another 2.5 years...low powered tube gear is best w/Klipsch...

No such thing as never looking lol, but I dont see my Innersound EROS MKII speakers for a long, long time

I agree with the original poster regarding Green Mountain Audio and Roy Johnson. I have the third pair of Diamantes that Roy made for sale. They have gone through three upgrades. What an incredible product! I suspect that if I listened to some of GMA's later efforts, I would undoubtedly fall in love with them. However, I am still so happy with my "old" Diamantes that I don't see the point. At the time of my purchase, I listened to so many relatively high-end contenders. Selecting the Diamantes, considered one of my great decisions, was second only to selecting my wife. And, yes, there were a few auditions for the latter role.
