Lalitk, you are so correct. Getting foundational stuff correct makes everything in the system perform its best, but it is very unglamorous. It's like getting underwear and socks for your birthday instead of a new bike! I am learning that power, isolation, room accoustics, cables, tube rolling, very non-sexy stuff is transforming my system into a much more engaging and rewarding sound. Buying expensive large components is way more fun, but without integrating each component with the rest you don't get the full benefit of your investment. A couple of years ago I bought a used Vivaldi Stack. This was the most expensive investment I had made in this hobby. After I wired the money the broker suggested that the previous owner would sell me his Nordost loom for a super low price of 47K. I'm sure they would have sounded great, but I was out of my lane. I could afford to buy the component, but I didn't have the money to integrate it. I sold the stack and went with a much simpler approach that I could afford to optimize.
