Obsession with upgrades was a serious disease I had until fairly recently. The biggest upgrade was changing my listening room so my speakers could show their best. Before, I was chasing my tail on the upgrade merry-go-round. Some choice improvements in the analog front end has landed me in a very comfortable spot, one I don't feel the need to change anytime soon.
Having components modded has made the difference also for me, instead of spending more on components I couldn't really afford, I spent relatively small amounts on upgrades to the components themselves. Satisfaction has arrived, the compulsion to upgrade has been all but vanquished, and it feels great.
I realize this approach is not for everyone, since many feel that having a stock marque product with a name and model number that says "high end" is a priority, and that's fine for those that can afford to do so. Along with many other members, that's not the case for me, so I had to get to the point where I could attain audio peace another way. The main thing is that you get there.
Peace and audio joy to all,
Dan
