I started my latest system in 2013 - committing to tubes and all separate components. I just finished a major upgrade to it - speakers, isolators, rack, conditioner, duplex socket, power cords, & new transport (CD, SACD, Memory Stick). I like the way it sounds now, especially better at low volume. I buy everything used (except the rack, IPAD), so, that really helps the pocket book. Since I am committed to tubes, I doubt I will upgrade much in the coming decade. If I decide to pay for true high res steaming instead of exclusively using my transport for my many personal high res songs, I may upgrade the DAC and my IPAD streaming setup. As the streaming technology continues to improve, that is where I see my future money going... Currently, I am only streaming "low/medium" res.
