Bluesound’s new Powernode promises more power and less distortion
August 1, 2025 Comments Off on Bluesound’s new Powernode promises more power and less distortion
The Bluesound Powernode was something of a pioneer in the world of streaming amplifiers, so a new model is always big news. The 2025 incarnation (called, like its predecessor, simply ‘Bluesound Powernode’) offers more power while promising less distortion and smarter home integration.
The 100W per channel of ‘DirectDigital’ amplification is an upgrade on its predecessor’s 80W per channel of ‘HybridDigital’ amplification.
The device is designed for “people who want powerful sound in a simple, streamlined package – a way to stream music and enjoy TV without the clutter and confusion of multiple boxes, remotes, or wires,” Bluesound says.
NiPO A100 $399 Review
August 1, 2025 Comments Off on NiPO A100 $399 Review
The NiPO A100 is a linear sounding device with a clean profile, which seems to be another one of NiPO’s niche points. The frequency response is well extended, covering deep bass, and to highs that produce lots of sparkle.
The background is dark, and there is no hiss perceived, even with sensitive IEMs. This darkness makes way for a clear view into the music it’s producing.
Kiwi Ears Septet $269 Review
July 31, 2025 Comments Off on Kiwi Ears Septet $269 Review
The bass on the Kiwi Ears Septet is excellent, with a clear focus on clarity and definition rather than weight or boom. Each note is precise, letting the character of bass guitar strings come through with ease.
Sub-bass rumble is present and felt, adding depth and body to the overall sound and preventing any sense of dryness. Mid-bass is controlled with a quick decay, making sure it never muddies the rest of the mix.
There’s a refined quality to the tuning, with the low-end never sounding forced or exaggerated. Subtle details from drum hits are easy to pick out, and each low-frequency sound lands with its distinct shape.
The bass here is not energetic or overwhelming, instead leaning into a more balanced and natural presentation. The emphasis is on texture and subtle impact, letting each part of the bass register be heard clearly.
Cayin RU9 $499 Review

I personally found the modern tube mode to strike the best balance, especially when paired with my Shanling HW600 – awesome headphone by the way- but more on that later.
Even better, the signal path remains powered by premium components at every step: JRC NJW1195A volume controller, dual LDOs (TPS7A4901 + LP5907), and a low-ripple LT8334 DC/DC converter – the kind of layout that screams no-compromise engineering.
The result? A circuit that not only handles high-resolution files with ease, but delivers them with finesse – whether you’re plugged into the balanced 4.4mm out or the regular 3.5mm jack. An outstanding foundation for the RU9’s dual-amp topology, and one that clearly sets it apart from mid-range competitors – despite the relatively low price of the DAC.

The FiiO S15 offers remarkable sound quality that harmonizes technical skill with musical expression. It provides a clear, effortless audio experience defined by a neutral-warm tonal profile. This device showcases a smooth tonal balance and accurate imaging, featuring excellent resolution and detail retrieval.
Central to the S15’s performance is its capability to merge technical excellence with emotional depth. It exhibits impressive resolution, transparency, and detail retrieval while ensuring an emotional connection that allows each note to be delivered with precision and nuance. This results in a polished sound character that reflects maturity and high quality.
Moreover, the S15 excels in areas such as left-right channel balance, transient response, and spatial separation, all of which contribute to its exceptional sound quality. The soundstage is broad, and the layering is skillfully executed, creating an engaging and immersive auditory experience.
SMSL PA-X Review

There are plenty of warm-sounding sources on the market, and when taken together, you can pair the PA-X with one of those to tailor the sound. Or pair it with a flavored DAC to suit your needs.
The PA-X tuning pushes the midrange slightly forward, but not at the expense of either end or near-neutrality. I did find that to get the best details out, the volume must be pushed higher than one might expect, but there is plenty of headroom for that.
The ability to pair with a comparable DAC makes for an enticing Opportunity to play around with the sound, too. This is where the iFi and Geshelli Labs came into play, and both represented a positive effect on the PA-X.

Perlisten Audio D15s Subwoofer Review
July 29, 2025 Comments Off on Perlisten Audio D15s Subwoofer Review
THX Dominus is the next step in the certification from THX in terms of objective performance in a loudspeaker (a subwoofer is a loudspeaker, something we tend to forget). In objective terms, a THX Dominus certification means the speaker in question can deliver SPL levels of up to 120 dB in rooms of up to 6,500 cubic feet. This is more than double the 3,000 cubic foot requirement that THX Ultra has, and it demands that a subwoofer has some serious firepower. The fact that Perlisten was able to achieve Dominus status with a single 15-inch driver is remarkable. The listening sessions bring the subjectivity of good sound to the objectivity of good science built into this subwoofer. Being the greedy bass soul that I am, the thought of “what would a pair of D215s do in our theater room if a single D15s is bringing home such power?” Each D215s brings dual 15-inch drivers to the party, and the thought of having a quad pack of these drivers trying to dismantle our theater room is a fun concept, to say the least!
