Nice to read your journey. I own the CEC TL-5 and ran across this thread and liked how you stayed on top of it and gave updates. A story all it's own. I bought the CEC TL-5 in 2020. Over the last few years, worsening tinnitus had me selling all of my equipment. As I was about to sell off my records, a friend convinced me to try another system, so I kept the CEC because I have twice as many CD's as LP's (6000 vs 3000) and I kept my DAC, the Mhdt Orchid. The CEC/Orchid combo had beaten all the players I've ever heard in my system and today, after getting a smaller, less revealing setup, I'm still happy with the performance. CD's sound less digital, still not as much headroom as LPs, but damn good to me. With my hearing woes, upgrading doesn't hold any value, but still interesting to read how it goes with others.
Congrats! Unlike Bono, it sounds like you've found what you've been looking for.
