ORIVETI OH700VB VS Symphonium Giant

Youtube Video Summary

Symphonium Giant comes in at $700 with a head-scratching spec sheet that vaguely says “hybrid BA + custom-tuned DD” while shouting about a 7Ω impedance. That ultra-low load is the story: it makes the set absurdly cable-sensitive—swap wires and the tonality shifts from lively to dull in a heartbeat. The stock cable keeps things intact; an Effect Audio swap noticeably softens detail, while a cheap Flare cable warms the signature and adds thickness. Tip rolling matters too (wide-bore DUNU SS versus “Render” tips), and even sources react; a portable FPGA DAP bleeds battery into that 7Ω sink, whereas a tube hybrid (Orchard Audio Valencia) injects welcome warmth and space. Packaging and labeling feel small-batch—serial plaques and sacks galore—but the box design and shell labeling are meh.

When set up right—stock cable, DUNU SS tips, and a touch of tube—Giant delivers a surprisingly large soundstage, clean mids, and impactful bass when the mix calls for it. Chain variance, though, is wild: vocals and treble clarity swing with every wire and amp, and the wrong pairing turns the tuning boring. As a value play, the performance fits closer to a strong $500 bracket; accessories are basic, and the tuning lacks the bombastic sparkle of Symphonium’s Crimson. Verdict: fine to recommend with caveats—use the stock cable, avoid high-resistance wires, and give it a warm front end. Treat the 7Ω spec with respect, or the Giant shrinks fast.
