I do feel genuine empathy for you that the money you recently spent on their gear is now virtually worthless.
I am sorry however this is a completely ridiculous statement.
I purchased my DarTZeel pre and amplifier at the end of 2023 after living for more than 20 years with a totl Naim 552/500. How is the money I spent on DarTZeel now worthless? I did not purchase my system to use and then sell. I purchased it to provide me with passionate music.
I like to rationalize my expensive purchases in the uber end of hifi utilizing the model of amortization. My Naim 552/500 has a list price of $70k. It gave me 18 years of stellar use and immense enjoyment. Amortized the cost to me was $3900 a year or $325 a month to listen to world class hifi. As I like to joke with my friends, there are those who spend more than $325 a month at Starbucks sipping mocha joka lattes.
I expect my DarTZeel components to carry me through for the next 10-20 years - so no - the gear is not "worthless". Same with my dCS Rossini and Linn LP12. Both do not owe me anything - their costs have already been recouped in listening pleasure.
