For those of you who had spent over hundred thousand dollars for your sound system.

Oh...  And for those who have to face the Wife Acceptance Factor, my problem is on two fronts !  Factor #1...  Shes a spend-thrift !  So anything I buy has to be purchased with, ahem... discretion !  Factor #2...  She's an interior designer !  So if it doesn't fit the decor (within reason) it's a non-starter !  When we moved to our retirement home ~2-years ago, we really had to down-size so my listening room went from a 15 X 18 room to a 10 X 12 listening space.  I let her have full run of the house in decorating/colors, etc., however, in my listening space, I reserved the right to set-up/ use what I need to improve the listening.  She agreed.  The only reason that I am able to get my final set of speakers is that it's a retirement present that I'm giving to myself !  Good Luck to all of you out there who have similar challenges when upgrading !  

I have spent nearly $300K in purchases and subsequent sales of electronics and speakers over the 40-years that I've been heavily into listening.  I evolved from very inefficient to rather inefficient to efficient to soon very efficient speakers over that time and of course the respective HiFi equipment especially amplifiers that go with that evolution.  As for regrets, the only ones I have over the past 40-years are in those pieces of equipment that I purchased by reviews and had not auditioned, which thankfully were not many !  Many of my purchases were new (all speakers) and most electronics so re-sale brought me ~1/2+ the original cost.  Thankfully, on my evolution to more-efficient speakers, my last 3 amplifier purchases will work great with my soon final set of very-efficient speakers.  Most recently, I've incrementally upgraded my exclusively digital front-end to components that have made my digital music enjoyment on equal or surpassing my past vinyl days.  So unless things in the digital realm change notably for the better (I would assume they would !), I will be finished with spending for both electronics and speakers.  One thing that I've seen in this thread and I completely agree with is investment in room acoustic treatments !  They can certainly make your musical experience better appreciated and tend to be the lowest-cost upgrades for improvement that an audiophile can make...  Here's to your intelligent investments !  Happy Listening !
