One is a streaming all-in-one and the other is an amplifier. Judge them on how many boxes you want and what you already own, not on the spec sheet alone.
| Area | Better | Why |
|---|
| Power | evenly matched | Effectively the same output - 40W against 45W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Room size | depends | We rate ELAC DS-A101-G the better fit for desk or near-field listening, and LEAK Stereo 130 for a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | A | ELAC DS-A101-G holds up better into a 4-ohm load: its output nearly doubles to 80W, where the other increases modestly. That matters with demanding speakers far more than the 8-ohm figure does. |
| Noise floor | B | LEAK Stereo 130 is the quieter design on paper - 108dB against 101dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Both decode on board. LEAK Stereo 130 goes higher - 384kHz against 192kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | evenly matched | Only ELAC DS-A101-G has Roon. Neither list is longer in a way that matters - check the one service you actually pay for. |
| Analogue inputs | evenly matched | The same number of line-level inputs (2). |
| Phono stage | depends | LEAK Stereo 130 has a built-in phono stage (MM) and ELAC DS-A101-G 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 | evenly matched | The same expansion options on both. |
| Headphones | depends | Only LEAK Stereo 130 has a headphone output. Worth something if you listen late, nothing if you never do. |
| Shelf space | depends | ELAC DS-A101-G takes up about 33% less shelf area (746cm² against 1115cm²). |
| Price | A | ELAC DS-A101-G costs less - $850 against $995 at list. |
A ELAC DS-A101-G B LEAK Stereo 130
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?
The usual trade-off: LEAK Stereo 130 measures better, ELAC DS-A101-G costs about 15% less. With most speakers in most rooms that gap is smaller in practice than it looks here. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - ELAC DS-A101-G is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. If you play records, LEAK Stereo 130 saves you buying a phono stage; if you do not, ignore that row entirely.
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.
