Both are Audiolab, from different ranges - the engineering approach is shared and the differences are mostly in power, connectivity and price.
| Area | Better | Why |
|---|
| Power | A | Audiolab 7000A has more power - 70W against 50W into 8 ohms. That is about 1.5dB, which is a small step in loudness but real headroom on peaks. |
| Room size | depends | We rate Audiolab 7000A the better fit for a mid-size room, a large room and a very large room, and Audiolab 6000A for desk or near-field listening and a small room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output increases strongly (110W and 75W). |
| Noise floor | A | Audiolab 7000A is the quieter design on paper - 110dB against 76dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | A | Both decode on board, but only Audiolab 7000A handles DSD and MQA. |
| Analogue inputs | B | Audiolab 6000A takes more analogue sources - 4 against 3. |
| Room to grow | evenly matched | The same expansion options on both. |
| Price | B | Audiolab 6000A costs less - $899 against $999 at list. |
| Watts per dollar | A | Audiolab 7000A is the cheaper watt - about $14 per watt against $18. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Audiolab 7000A B Audiolab 6000A
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?
Audiolab 7000A leads across most of the measured areas for a fairly modest premium, so it is the easier pick if the budget stretches. Audiolab 6000A is the one to take if it does not.
What a spec sheet cannot show: how either sounds with your speakers, how the interface feels 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.
