These are not the same size of amplifier: LEAK Stereo 230 has roughly 3x the power of Rotel DX-5. That is about 4.8dB, so it is a question of room size and how hard your speakers are to drive, not of one being the better amplifier.
| Area | Better | Why |
|---|
| Power | B | LEAK Stereo 230 has more power - 75W against 25W into 8 ohms. That is about 4.8dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Grip on hard loads | B | LEAK Stereo 230 holds up better into a 4-ohm load: its output increases strongly to 115W, where the other increases modestly. That matters with demanding speakers far more than the 8-ohm figure does. |
| Noise floor | B | LEAK Stereo 230 is the quieter design on paper - 109dB against 100dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Both decode on board. LEAK Stereo 230 goes higher - 768kHz against 384kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | evenly matched | Only Rotel DX-5 has Roon. Neither list is longer in a way that matters - check the one service you actually pay for. |
| Phono stage | depends | LEAK Stereo 230 has a built-in phono stage (MM) and Rotel DX-5 does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Room to grow | B | Only LEAK Stereo 230 offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Shelf space | depends | Rotel DX-5 takes up about 58% less shelf area (610cm² against 1454cm²), and it is 159mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | LEAK Stereo 230 is the cheaper watt - about $23 per watt against $68. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Rotel DX-5 B LEAK Stereo 230
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
LEAK Stereo 230 has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - LEAK Stereo 230 is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - LEAK Stereo 230 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 25 watts is already more than most people ever use, and the extra 50 watts would be headroom you pay for and never hear - we rate LEAK Stereo 230 poorly for near-field use for exactly that reason.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
