Geek Out 450 from LH Labs - Pocket-sized USB DAC and Amp

The video opens by setting a skeptical tone toward LH Labs claims, noting that the Geek Out 450 is from the same company behind the controversial Lightspeed USB cable. The host frames a measured hands-on review, acknowledging that some of LH Labs’ assertions may be exaggerated while still evaluating the device on its own merits. It is introduced as a pocket-sized USB DAC and amplifier with broad compatibility, capable of handling audio from low quality MP3s to high resolution formats including 384 kHz, 32-bit PCM and even DSD 128. The reviewer describes the build and physical design, highlighting a compact aluminum housing, front LED indicators, a back panel with a helper display, and dual headphone jacks for shared listening. He explains the internal controls, including volume buttons with fine adjustment, a 3D audio feature, and notes that the 3D effect can be distracting in some cases. He also emphasizes the device’s driver situation across operating systems, pointing out Linux and Mac support without drivers, while Windows requires a specific driver due to asynchronous USB audio Class 2 support, and he walks through the basic setup steps after drivers are installed. The testing methodology is detailed, including a sound-level meter to equalize volume across amps using a 1 kHz tone at 85 dB, and then performing side-by-side listening across various music formats. The host uses multiple headphones to assess performance, comparing to a prior amp (the E10) and asserting that the Geek Out 450 delivers clearer, less distorted sound at reasonable listening levels, especially with high-bitrate files. In the listening phase, he experiments with different formats such as 320 kbps MP3, FLAC at 192 kHz, 24-bit high-resolution, and finally DSD 128, attempting to discern audible distinctions. While recognizing that very compressed MP3s are typically poor, he notes that high-resolution files sometimes reveal subtle differences but often not enough to justify the extra storage and cost for his preferences. The conclusion centers on objective merits: excellent format compatibility, portability, and the sense of having a more capable device than a standard PC audio path. He notes the device runs hot, warns about heat in Massdrop promotions, and segues into sponsor content and community engagement, including Massdrop’s interactive group buys and a contest offering a Mod Mic 4.0.
