HiBy R8 II Review: The Neutral Reference DAP Under $2,000

I’ve been watching HiBy’s trajectory for a while now, and the R8 II is them arriving where I suspected they were headed: a reference-class DAP at a price that doesn’t require a second mortgage. I picked one up at launch — $1,699 — and spent about two months with it as my daily carry. My prior daily driver was the Astell&Kern SE300, which is a fine device, and the R8 II made me reconsider that relationship quickly.

What “Neutral Reference” Actually Means to Hear

The dual ES9038PRO implementation isn’t just about specs — it’s about a listening philosophy. HiBy isn’t trying to give you warmth or excitement. They’re trying to get out of the way. And when you load up a well-recorded album — I started with Patricia Barber’s Café Blue in DSD64 — the R8 II delivers the kind of transparency that makes you feel like you’re hearing the recording chain rather than the DAP’s personality.

That cuts both ways, and I want to be upfront about it. A perfectly mastered acoustic album through the R8 II sounds absolutely extraordinary. But a brickwall-limited modern pop master — something like early 2010s mainstream radio fare — sounds exactly as bad as it was recorded to be. The R8 II reveals. It doesn’t flatter. If that sounds like a feature to you, it is. If you’d rather have a player that smooths things over, look at something warmer-tuned.

Android 12 and the Streaming Integration Story

Here’s where the R8 II separates itself from competitors in the same price bracket. The Qualcomm 665 platform with 6GB RAM runs every streaming app without complaint — Tidal, Qobuz, Amazon Music HD, Apple Music, Spotify, you name it. HiBy’s Darwin 2.0 architecture does the hard work of maintaining bit-perfect output through Android’s audio stack, which is normally a nightmare. The result: I can stream Tidal Masters at full MQA unfold directly from the R8 II without touching a laptop or separate DAC.

The MSEB (Mind-blowing Sound Enjoying Brain) DSP is something I expected to ignore, but I’ve used it occasionally for specific recordings. It’s a parametric tool that lets you nudge warmth, air, and bass presence without breaking the signal path. On a few DSD albums that skew a bit thin in the upper bass, a tiny push via MSEB corrects it without making the device sound processed. I don’t use it as a default, but I appreciate that it exists and doesn’t feel intrusive.

Driving Power: What the R8 II Can Actually Control

1,000mW into 32 ohms balanced is real headroom. I tested the R8 II with my HiFiMAN Arya Organic — a planar that benefits enormously from current delivery — and it drove them cleanly to high volume with authority and grip in the bass. My Sennheiser HD 800 S also responded well. I would not call the R8 II a replacement for a dedicated desktop amp for truly demanding planars (Susvara, Abyss), but for everything short of that, it handles itself with confidence.

Build quality is substantial — aerospace aluminum, 316g, 5.98-inch AMOLED display. It’s not slim and it won’t fit in a jeans pocket comfortably, but it survives in a bag without making you nervous. The physical volume wheel has good weight and detent feel. One downside: no replaceable battery, which at this price point feels like an oversight. Battery life at around 10-12 hours balanced is adequate but not exceptional.

Verdict

Worth it at $1,699? Yes, without much hesitation — if you’re a serious listener who wants neutral transparency, Android streaming integration, and real driving power. The R8 II outperforms its price class on technical merit and it sounds fantastic with well-recorded material. Worth it at $2,000? Still yes. The neutral tuning philosophy isn’t for everyone, but if it’s for you, the R8 II is the best expression of it in a portable form factor.

Tested with: HiFiMAN Arya Organic (4.4mm balanced), Sennheiser HD 800 S (3.5mm), Campfire Solaris SE (IEM). Music sources: Tidal HiFi Plus, Qobuz Studio, local FLAC and DSD64. Testing period: 8 weeks.
