The Carina GaN and Carina X. The best integrated amplifiers we have ever made, period.
One question we get asked often is: why make both, and what’s the difference?
The answer is actually pretty simple. They are identical everywhere except for the power amplifier section.
The Carina GaN uses a novel GaN-FET amplifier with a zero feedback design and a regulated power supply. It is the same amplifier used in our widely acclaimed GaN-1.
The Carina X uses a MOS-FET amplifier with a high feedback design and an unregulated power supply. There is nothing inherently groundbreaking about the topology itself, but it represents one of the best executions of a power amplifier we have heard to date.
The amplifier section is also available as a standalone power amplifier, the Stereo X.
That’s the high-level overview. But the real reason both products exist at nearly the same price point is because of the sound quality. They both achieve a remarkable level of transparency that makes us feel like we are hearing the music, not the gear. That is something we never take for granted.
Of course, every design approach comes with tradeoffs.
The Carina GaN takes a “less is more” approach. The audio path is extremely simple and pure. Because GaN-FETs switch so cleanly, we are able to eliminate the feedback loop entirely. Without a feedback loop, the signal is not subjected to the phase and timing artifacts that can exist in feedback-based designs. The tradeoff is that the amplifier is a little more dependent on the speaker load. The regulated power supply also places a ceiling on the power output regardless of impedance.
The Carina X takes a different approach. It uses a large amount of feedback to correct the inherent switching imperfections of MOS-FET output devices. The advantage is that it is much more speaker load agnostic and exceptionally stable into difficult loads. Historically, many high-feedback designs developed a reputation for sounding sterile or mechanical, but the technology used in the Carina X is one of the very few implementations we have heard that simply does not suffer from those shortcomings.
So which one should you buy?
If you have higher impedance speakers, roughly 6 ohms or above, and relatively high sensitivity, around 88 dB or greater, we generally recommend the Carina GaN.
If you have more demanding speakers, or may eventually change speakers, especially 4 ohm designs with lower sensitivity, we generally recommend the Carina X.
But here’s the interesting part.
In carefully matched blind listening tests here, we do not hear a discernible sonic difference between them. Both are exceptionally clear, open, and transparent to the music.
It’s a little like choosing between two engines in a car. An inline six or a V6. Different approaches, but both can deliver the smooth, effortless performance required to make the experience feel seamless.
It would certainly make our lives easier to offer just one model in this price range, but we simply could not declare one “better” than the other. Both approaches have real strengths and achieve the level of transparency we were aiming for, which is why we are proud to offer both.
