Upgrade in the right order and the same money buys a bigger improvement. Upgrade out of order and you can spend plenty and hear nothing change.
Before you buy anything
Put your speakers at the points of an equal triangle with your listening position, tweeters at ear height, and pull them 20 to 30 cm off the wall behind them. Then experiment with how much they angle inward. An afternoon of this routinely surprises people, and it's the only upgrade in Hi-Fi that costs nothing.
Then in this order
- Speakers. The largest single jump available, because old speakers set a ceiling nothing downstream can lift.
- Amplifier. It matters when it's genuinely underpowered for your speakers, or when the old one is failing: hum, channels cutting out, running hot. A healthy mid-priced amp driving easy speakers is rarely the bottleneck people assume it is.
- Source: streamer, DAC, turntable. The smallest gains, until the rest of the chain is sorted.
Not fooling yourself
- One change at a time. Two at once and you can't tell which caused what.
- Live with it a week. First-evening impressions are mostly novelty and expectation.
- Match the system. A €2,000 amp pushing €200 speakers is a worse system than the reverse for the same money.
After speakers, the room itself is the upgrade: rugs, curtains, a shelf full of uneven book spines. Rooms reinforce some bass notes and swallow others depending on their bare dimensions, which is why the same speakers sound different in two living rooms. It's the one component every listener agrees on and nobody can sell you.
