The Syncro Uni 16 A rebalances the sine wave around the zero line and eliminates DC components up to 4 volts. The V5 circuit delivers 260% more current capacity than the previous generation (internal peak current 32 A), uses 36 copper\/silver capacitors at 169,000 µF and silver-plated 6N-OFC conductors with FEP dielectric. The board could easily run at 32 A – conservatively limited to a 16 A input for reliable continuous performance. Thermomagnetic protection buffers spikes above 500 A.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe same calm as the 10 A version – just with headroom for the very largest transformers. The hum from the power amp disappears, the background turns pitch-black, bass gains contour and authority. Because saturation is no longer an issue, the power amp draws current unrestrained at the big drum hits.\u003c\/p\u003e\n\u003ch3\u003eWho is the V5 Syncro Uni 16 A for? (and who it's not for — straight talk)\u003c\/h3\u003e\n\u003cp\u003eFor power-hungry power amps and monoblocks – or as a pre-filter ahead of a complete chain or a large power strip. \u003cstrong\u003eStraight talk:\u003c\/strong\u003e for a normal integrated amp, the 10 A version is more than enough; the 16 A only pays off once real current is flowing or an entire system hangs behind it. And the chassis is substantial – plan a fixed spot in the rack, not the wire basket behind the system.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe powerful variant of the Syncro principle: 32 A of headroom, C20 input, built for powerhouses and entire systems. If a large power amp hums or you want to run the complete chain through a pre-filter, the 16 A is the right choice. The trade press sees it the same way: the V5 Syncro Uni 16 carries the hi-fi+ Editor's Choice Award 2026.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: DC blocker \/ mains pre-filter (active DC elimination)\u003c\/li\u003e\n\u003cli\u003eFunction: rebalances the mains sine wave, removes DC components up to 4 V\u003c\/li\u003e\n\u003cli\u003eInternal peak current: 32 A (input limited to 16 A)\u003c\/li\u003e\n\u003cli\u003eMains input: IEC C20 (compatible with EVO3 Premier C19 cable)\u003c\/li\u003e\n\u003cli\u003eMains voltage: 100–240 V \/ 50–60 Hz\u003c\/li\u003e\n\u003cli\u003eCapacitors: 36× copper\/silver, 169,000 µF\u003c\/li\u003e\n\u003cli\u003eSurge protection: thermomagnetic, buffers above 500 A\u003c\/li\u003e\n\u003cli\u003eInternal wiring: 6N OFC, silver-plated, FEP dielectric\u003c\/li\u003e\n\u003cli\u003eChassis: steel and aluminium\u003c\/li\u003e\n\u003cli\u003eDimensions (W × H × D): 150 × 85 × 250 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 2.0 kg\u003c\/li\u003e\n\u003cli\u003eVersions: Silver \/ Black, each in CH or EU version (Schuko)\u003c\/li\u003e\n\u003cli\u003eWarranty: 2 years, extendable to 3 years with registration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between the IsoTek V5 Syncro Uni 16 A and 10 A?\u003c\/h3\u003e\n\u003cp\u003eThe 16 A version has a larger C20 input, higher current headroom (32 A peak instead of 16 A) and more capacitor capacity. It's meant for powerful power amps or as a pre-filter ahead of an entire system; the 10 A is enough for individual integrated amps or sources.\u003c\/p\u003e\n\u003ch3\u003eWhich mains cable do I need for the Syncro Uni 16 A?\u003c\/h3\u003e\n\u003cp\u003eBecause of the larger C20 input you need a cable with a C19 plug, for example the IsoTek EVO3 Premier.
