If there is one thing you could change in your current system. What would it be?

I can vouch for more power on Maggie 3.7i's.   They come alive with more power.

Me. I would change me so I'm more fiscally responsible and less of a elitist pain in the ass when it comes to Fidelity and Sonic quality. It would make life so much easier and affordable.

@simao i understand but when you get great sound we chase and chase. Wallet be damned

Interesting, I look at this completely opposite from the way you do.

From my point of view, now that I am 72 and have upgraded and stretched to financially afford the system I have built over the last fifty years. Which I researched endlessly, built and  listened to by myself.

I am thankful that I stretched the limit of my financial ability, that I did not hold back and settle for anything less than the very best sound quality. I purchased cheap TP, used cars instead of new, did my own yardwork and household repairs so I could invest in my system. It brings me great joy on a daily basis and stands as an achievement of one of my dreams of a young adult. 

You only live once, and when you get to retirement, you want to be able to look back and say "the time was well spent it... these are my experiences". I am very fortunate to have a very long list of these things, and my audio system is one of them... and it  isn’t made up of Schiit. Well... ok, I have a Schitt DAC in my office system, and a Schitt preamp for burning in cables. But my main system is great.

@ghdprentice i started with a system that was $3500 in the beginning. Well its 20 years later and lets just say every component cost way more than that. But our systems are our joy. Some like cars we like audio. I went  for it and got the sound I sought. Enjoy. We all have these audio journey.
