While I agree that your approach makes sense for those willing to spend considerable sums for higher end gear, I've taken the approach of reducing my spend, while increasing my satisfaction by buying older or more utilitarian gear, having been dissatisfied with higher end / higher priced mainstream gear and no longer willing to pay the rapidly increasing prices of mainstream high end gear.
Examples of changes I've made in which I've saved money (or minimized spend) and increased my satisfaction:
- Refurbished Altec Model 19's replaced and are more enjoyable than my previous Harbeth 40.2 Anni's
- DeHavilland UltraVerve 3 preamp outperforms previous Aesthetix Calypso Signature
- Roon Nucleus paired with Ifi Zen Stream as ROON endpoint sonically outperforms and is more dependable than previous Aurender N10
- Duelund speaker cables outperform my previous Auditorium A23 speaker cables
- Duelund power cables outperform my previous Cardas PC's
- Quicksilver amps are utilitarian, with minimal expense towards aesthetics. But they sound good and are reasonably priced.
- I bought a used Weiss 202 DAC for $1750 , but it retailed for approx $7,300 and was predecessor to the current 501 DAC that retails for around $10K.
In summary... I don't disagree with your approach... but for those unwilling or unable to spend $15K for amplifiers and $15-25K on speakers, excellent systems can still be obtained for far less if done carefully. In my case, I've increased my satisfaction by replacing higher priced gear with lower priced higher value and/or older gear that work well together.
