Octave is an audio brand that offers high-quality audio products.

The Octave RE 320 stereo power amplifier represents a progressive development in its product line, integrating superior SE technology previously showcased in the Octave V 80 SE integrated amplifier. This technology enhances the amp's stability and linearity, especially notable in its adoption of the modern KT 150 power pentodes. These pentodes facilitate impressive output levels — about 2 x 130 W in push-pull mode, with pulse power soaring above 200 watts, ensuring broad dynamic range and sound integrity across frequencies from 5 Hz to 85 kHz.

Roland Kraft's review in Stereoplay highlights the RE 320's compatibility with a wide array of loudspeakers, attributing its performance to the minimal interference signal level of more than -110 dB which eradicates hum and noise, even with high-efficiency speakers. This makes the RE 320 highly versatile and capable of delivering clean, expansive sound.

In addition to its robust audio performance, the RE 320 is packed with user-centric features to enhance usability and longevity. Fine adjustments of BIAS, a power switch accommodating different tube types, and an innovative ECO mode for energy efficiency are just a few of its practical elements. It also offers flexibility in connectivity with both RCA and XLR inputs and is equipped with a comprehensive power management system that includes soft start electronics to protect the device and prolong its lifespan.

Physically, the RE 320 comes in either silver or black designs, accommodating aesthetic preferences while maintaining a classic look that fits well with various interior designs. Its construction is thoughtful with a user-friendly interface, and dimensions stand at 488 x 210 x 410 mm, weighing 27.6 kg. This amplifier is not only a powerhouse in performance but also a centerpiece in any audiophile's collection, promising reliability and superior sound quality. Such attributes reflect Octave's commitment to unparalleled excellence in audio technology.

This isn't an exhaustive review with numerous tests. Instead, it's an initial attempt to select a phono preamp within a budget from well-known models available on popular platforms like Amazon. While there may be better models or used options within the same price range, this post focuses on first impressions.

Our setup included McIntosh speakers, a custom-made turntable (limited edition but entry-level) with a brand new Ortofon S10 cartridge, a Denon receiver (to stay within the same price range), and a McIntosh headphone tube amp (MHA200) with McIntosh MHP1000 headphones for the final check-up.

The idea for this article stemmed from the need to connect our turntable to a Denon receiver, necessitating a phono preamp. We tested each preamp using tracks from Frank Sinatra, Sade, and The Weeknd to cover a range of vocal and instrumental styles, ensuring a comprehensive evaluation.

**Description and Sound Characteristics**  

The [Cambridge Audio Alva Duo](https://hifi.fan/cambridge-audio-alva-duo) offers clarity and precision, though it may lack some of the warmth and detail found in the Tube Box S2. It provides a clear sound that feels somewhat confined between the speakers. For its price, it delivers good performance, with vocals that are clear but might miss some mid-range or high details. The separation is adequate but not exceptional, sometimes sounding too pure and lacking colorization. It is relatively large and may require a separate shelf in a vertical rack. On the plus side, it includes an integrated headphone amplifier and supports both MC and MM cartridges, adding versatility.

**Impressions** 

Playing Sade on the Alva Duo revealed a slightly dull sound with no pronounced bass. While the sound was clear and detailed, it lacked the extension and separation that the Tube Box S2 offered.

**Pros and Cons**

Sony is rumored to be on the brink of launching a new chapter in its earbud series, the LinkBuds 2, stirring up conversations among tech enthusiasts. The whispers about these earbuds paint a picture of innovation and refinement, especially with the anticipated addition of noise-cancellation technology. This feature catches the eye because the original LinkBuds were known for their "open ring" design, which lets you hear the world around you. Integrating noise cancellation into this design raises questions and curiosity about how Sony has managed to pull off such a feat.

Leaks, particularly from The Walkman Blog, give us a sneak peek at what the LinkBuds 2 might offer. They're expected to provide an "elevated audio experience," potentially matching the sound quality of Sony's high-end WF-1000XM5 earbuds. This comparison sets high expectations for the LinkBuds 2, hinting at a superior listening experience.

From the technical standpoint, these earbuds are said to house the MediaTek MT2833 chipset, the same brain that powers the WF-1000XM5. This detail suggests that Sony is not holding back on the internal components, aiming for top-notch performance.

The design seems to pay homage to its predecessors, maintaining the unique open-ring structure but with slight modifications to the charging pins and driver holes. This indicates Sony's commitment to the original aesthetic appeal while probably enhancing functionality and comfort.

Color options seem to be expanding too, with leaks hinting at a classic black and a new light gray variant, offering a choice to match personal style preferences.

Battery life details are still under wraps, yet if we go by the original LinkBuds' performance, users can expect around five-and-a-half hours of playback time, which is pretty standard for earbuds of this caliber.

As for the release date, there's no official announcement yet. However, the appearance of these earbuds in regulatory filings suggests that Sony might soon unveil them, following the pattern of previous launches.

Summing up, the Sony LinkBuds 2 are shaping up to be a fascinating blend of innovative technology and unique design. They promise to challenge the conventional earbud experience, especially with the integration of noise-cancellation into an open design. While we await more details, the rumored specs and features indicate that these earbuds could be a noteworthy addition to Sony's lineup, appealing to those who appreciate a mix of cutting-edge technology and distinctive style.

The audiophile community is buzzing about the latest release from FiiO - the R9. Touted as a game-changer in digital media streaming, this device has caught the attention of high-fidelity audio enthusiasts. Let's dive into what makes the FiiO R9 stand out, minus the technical jargon and marketing speak.

What's Under the Hood?
The FiiO R9 is more than just another streaming device. It packs some serious tech, like dual ES9038Pro DACs and an eight-channel THX 788+ amplifier. In simple terms, this means it can deliver really powerful and clear sound. The device runs on a customized Android 10 system, which they plan to upgrade to Android 12.

Connecting Your World
In today’s world, staying connected is key, and the R9 ensures you're not left wanting. It's equipped with Wi-Fi, which is pretty much expected in any modern device. For those who want to use it with a PC, the inclusion of an XMOS chip reduces latency - a fancy way of saying it keeps sound and visuals in sync. The R9 also comes with HDMI ports, but it’s important to note that while you can connect it to an external monitor, don’t expect to use your monitor's touchscreen capabilities with it.

Not Just for One Corner of the World
FiiO seems to understand that their audience is global. The R9 comes with different power cables depending on where you are in the world - a small but thoughtful detail. This means less hassle finding the right adapter or cable.

More than Just the Product
There's some excitement around the launch promotions too. For instance, ordering the R9 from their AliExpress store gets you a free portable DAC and headphone amplifier. That's a nice bonus, especially for those who love collecting audio gear.

The discussions around the R9 aren’t limited to this product alone. People are curious about updates for other FiiO devices, hinting at a loyal customer base waiting to see what else FiiO has up its sleeve.

So, What’s the Verdict?
The FiiO R9 seems to be making waves for good reasons. It’s not just another high-end audio device; it’s a well-thought-out piece of tech aiming to deliver a top-notch audio experience. While it’s packed with advanced features, FiiO seems to have kept the user experience in mind, making it accessible and not overly complicated. It will be interesting to see how it fares in the real world, beyond the initial excitement. For those deep into the world of high-quality audio, the R9 could be a gadget worth checking out.
