From Cambridge Labs to Your Component Stack

Since 1983, Audiolab has quietly revolutionized British hi-fi from their Cambridge headquarters. While others chased exotic materials and mystical claims, Audiolab's engineers focused on measurable improvements. Their 8000A integrated amplifier became the benchmark for affordable excellence, selling over 100,000 units. Today, Audiolab applies that same pragmatic engineering to solving real-world problems - like the DC offset that makes your transformers hum and your soundstage collapse.

The Transformer Whisperer That Actually Works

The DC Block 6 addresses the dirty secret of modern power grids - DC contamination that makes transformers vibrate, amplifiers clip prematurely, and music sound compressed. Unlike power conditioners that limit current or regenerators that cost thousands, this passive device simply removes the DC offset while leaving your AC untouched. It's the audiophile equivalent of cleaning your glasses - suddenly everything comes into focus.

Where British Engineering Solves American Power Problems

Pure Passive DC Elimination

• Zero current limiting: Full dynamic power delivery preserved
• Broadband DC blocking: Removes DC offset from 0Hz upward
• No active components: Nothing to fail, color, or limit your sound
• Instant operation: No warm-up, no adjustment, just plug and play

Six Isolated Outlets of Clean Power

• Hospital-grade outlets: Superior grip and conductivity
• Star-ground topology: Minimizes inter-component ground loops
• 15-amp capacity: Powers entire systems without restriction
• Surge protection included: 2,500 joules of spike absorption

"Removed a Layer of Grunge I Didn't Know Existed"

Hi-Fi News reported: "The DC Block 6 silenced transformer hum in three different amplifiers and improved clarity across the board."

The Absolute Sound noted: "Background became blacker, dynamics more explosive - like lifting a subtle veil from the music."

Engineering Excellence by the Numbers

• DC blocking threshold: >5mV DC offset elimination
• Current capacity: 15 amps continuous
• Outlets: 6 hospital-grade with brass contacts
• Surge protection: 2,500 joules
• Frequency response: No limitation 20Hz - 20kHz
• Dimensions: 17" W x 2.75" H x 8" D
• Weight: 5.5 lbs
• Construction: Aluminum chassis with steel baseplate

Where This DC Block Makes the Biggest Difference

• Toroidal transformers: Especially sensitive to DC offset
• Vintage amplifiers: Older designs particularly vulnerable
• Urban environments: Higher DC contamination in city grids
• Home theaters: Eliminates subwoofer transformer hum

Plays Nicely With...

• Power amplifiers: Any amp with transformer hum issues
• Integrated systems: Cleans power for entire component stacks
• Tube gear: Reduces mechanical noise without limiting dynamics
• Sensitive sources: Turntables and DACs benefit from cleaner grounds

Everything You Get

• Audiolab DC Block 6 in pristine "unused" condition
• Original double-boxed packaging
• Owner's manual and specifications
• Full 2-year Audiolab warranty
