Audio Circuit Design

DPPU(Desktop Plus Power Unit)：
DPPU adapts dual high-density battery customized power system, designed for High-Fidelity while ensuring separation of digital and analog power to eliminate digital circuit noise from the source, alike an enhanced DAP + Amplifier system but with a minimal path and hard soldered joints with no compromises.
Redesigned the charging circuit to reduce the switch circuit noise,ensure charging and playing at the same time, sound quality is not affected.

SG1 Power Design：

Normal Design:

The continuous evolution of Bluetooth technology, the development of aptx HD and LDAC protocols have made the wireless audio quality better and better.
According to the characteristics of Bluetooth digital signal output,SG1 selects appropriate DAC, well-designed LPF and headphone amplification circuit to make wireless sound tend to wired sound performance.

Software Design

Customize different firmware according to DAC and LPF circuits.
Different timbres through firmware instead of different accessories.

Inerface Design & CMF

Excellent control experience comes from the unique volume knob design.
The optimization of Touch &Feel algorithm makes the volume adjustment smooth and accurate.

Dethonray Pegasus SG1 — flagship wireless clarity in a pocketable package

The Pegasus SG1 Special Edition delivers unexpectedly refined Bluetooth performance, positioning itself as a go-to LDAC wireless source for critical listeners. Its sonic character is lush, thick and smooth, with a warm midrange, well-controlled bass and engaging dynamics that belie its compact form. Reviewers praise the improved tactile volume control and confident fit-and-finish, making the unit feel mature and durable in hand. Connectivity is modern and straightforward (USB-C and LDAC), and the SG1 is especially suited to mobile listening, desktop setups and tablet-based video/concert playback. While highly musical and excellent value at the quoted ~$359–400, some users should note a modest noise floor with very sensitive IEMs and that the Special Edition is primarily a Bluetooth receiver rather than a fully featured wired DAC/amp. Audiophilepure highlighted its polished experience and build improvements.

Audiophilepure

"The volume knob is much better and the build quality has no flaws."

Pros

Flagship-level wireless sound: lush, thick and musically engaging for a Bluetooth receiver.
Refined build and controls: improved, smooth volume knob and solid fit-and-finish.
Excellent price-to-performance: delivers near-flagship wireless performance at a very competitive price point.

Cons

Not completely silent: a faint background hiss can be audible with very sensitive IEMs.
Bluetooth-only focus: certain variants function as receivers rather than full wired DAC/amp solutions, limiting use for some desktop setups.
Sharp, angular case design benefits from a protective cover—minor practical vulnerability at the corners.

Sound Quality

90/100

Reviewers describe very engaging, musical playback and improved power on the SE/gold variant, suggesting good headroom and punch for most material. While dynamics are frequently praised, there are fewer explicit lab-style tests with power-hungry planars, so the score is high but not reference-level.

Noise Floor

72/100

Reviews note a "fairly low background noise" but also report a faint hiss audible with very sensitive IEMs (e.g., Fir Audio NE4, Campfire Atlas) when no music plays; less-sensitive IEMs show little background. Because audible hiss is reported with sensitive monitors, the noise-floor score is capped in the band appropriate for slight hiss with IEMs.

Headphone Compatibility

83/100

The SG1 is described as powerful for a Bluetooth receiver (gold variant with improved power) and suitable for most IEMs/headphones, but reviewers explicitly caution about faint hiss on very sensitive IEMs and the unit is not presented as a high-power wired amplifier for very demanding planars. Lack of published low output-impedance figures, gain-stage options, and wired high-power testing limits a higher rating.

Build Quality

90/100

Reviewers call out a much improved volume knob and say the build quality 'has no flaws,' praising the mature, sharp design. A minor practical note suggests including a protective case due to the angular corners, but overall construction and fit/finish are highly rated.

Features Connectivity

82/100

SG1 offers modern wireless features (LDAC Bluetooth) and straightforward pairing; product text mentions USB Type-C support. As a primarily Bluetooth receiver (not a full wired DAC/amp in some variants) it lacks the wide array of wired/balanced outputs and streaming features that would push this into the top connectivity band, so it scores slightly above the minimal baseline for having high-quality wireless codecs.

Value for Money

95/100

At the quoted ~$359–400 price the reviewer language is strongly positive ('super high' price/perf ratio, 'super friendly price', 'hard to beat', 'Hall Of Fame'), making the SG1 highly recommended for those seeking premium Bluetooth performance. The consensus framing of 'best Bluetooth receiver' and exceptional performance at this price supports a top-tier value score.
