Your Transformer is Humming (And Not in a Good Way)

Ever notice that annoying mechanical hum coming from your amplifier? That's not character—that's DC contamination in your power line making your transformer vibrate like an angry bumblebee. And here's the kicker: that same DC offset is also compressing your dynamics, muddying your soundstage, and making your expensive amplifier clip prematurely.

Since 1983, Cambridge-based Audiolab has been solving real hi-fi problems with proper British engineering. Their legendary 8000A integrated amp sold over 100,000 units not through marketing hype, but by actually working better than everything else at its price. The DC Block 6 follows that same philosophy: identify the problem, engineer a proper solution, skip the snake oil.

What DC Contamination Actually Does to Your System

Modern power grids are polluted with DC offset—a byproduct of all the switching power supplies, solar inverters, and LED dimmers connected to the grid. Your amplifier's transformer wasn't designed to handle DC, so it saturates, vibrates, and loses headroom. The result? Mechanical hum you can hear across the room, reduced dynamic range, and a veil over your music that you didn't even know was there.

The DC Block 6 fixes this with elegantly simple passive filtering. No current limiting. No active circuitry to fail. No "power conditioning" that actually makes things worse. It just removes the DC contamination and gets out of the way—like cleaning your glasses so you can actually see what you've been missing.

Six Ways to Clean Power Without the Compromises

• Zero Current Limiting: Unlike power conditioners that choke dynamics, the DC Block 6 delivers full power on demand
• Broadband DC Elimination: Removes DC offset from 0Hz upward—the stuff that makes transformers angry
• Pure Passive Design: No active components means nothing to color your sound or eventually fail
• Plug-and-Play Operation: No adjustment, no warm-up, no learning curve—just instant results
• Hospital-Grade Outlets: Six outlets with superior grip and conductivity that actually hold your plugs
• Star-Ground Topology: Minimizes ground loops between components for a cleaner noise floor
• 15-Amp Capacity: Powers your entire system without breaking a sweat
• Built-In Surge Protection: 2,500 joules of spike absorption protects your investment

What Happens When You Remove the Grunge

Plug in the DC Block 6 and the first thing you'll notice is the silence. That transformer hum? Gone. But the real revelation comes when you hit play. Suddenly there's air around instruments. The noise floor drops like someone turned off a fan you didn't realize was running. Dynamics jump—loud passages actually sound loud instead of compressed. Your system sounds like it just got upgraded, but nothing changed except the quality of your AC power.

This isn't subtle. This is the difference between listening through a dirty window and a freshly cleaned one. You didn't realize how much DC contamination was compromising your system until it's gone.

The Numbers Behind the Magic

• DC Blocking Threshold: Eliminates DC offset greater than 5mV
• Current Capacity: 15 amps continuous—no dynamic limiting
• Outlets: 6 hospital-grade with brass contacts
• Surge Protection: 2,500 joules
• Frequency Response: Zero limitation from 20Hz to 20kHz
• Dimensions: 17"W × 2.75"H × 8"D
• Weight: 5.5 lbs
• Construction: Aluminum chassis with steel baseplate
• Finish: Black

Where DC Block Makes Improvements

• Amplifiers with Toroidal Transformers: These are especially sensitive to DC—you'll hear immediate improvement
• Vintage Gear: Older designs are more vulnerable to DC contamination
• Urban Power Grids: Cities have higher DC pollution from all those switching supplies
• Home Theater Subwoofers: That annoying transformer hum? This kills it dead
• High-Resolution Systems: Revealing systems show the benefits of a lower noise floor

Where DC Block Does The Most Good

• Any Amplifier with Transformer Hum: If it buzzes when nothing's playing, this fixes it
• Entire Component Stacks: Six outlets means your whole system gets clean power
• Tube Amplification: Reduces mechanical noise without limiting the dynamics tube lovers crave
• Sensitive Sources: Turntables and DACs benefit from cleaner ground connections

Here's What You Get

• Audiolab DC Block 6 in black, brand new
• Original factory packaging
• Owner's manual and specifications
• Full 2-year Audiolab manufacturer warranty

Stop Living With Transformer Hum!

If your amplifier hums when nothing's playing, you've got DC contamination. If your system sounds compressed or lacks air, DC offset might be the culprit. The DC Block 6 fixes both problems with zero sonic downsides—no current limiting, no frequency rolloff, no active circuitry adding its own signature.

This is the most cost-effective solution to DC contamination available. No thousand-dollar power regenerators. No exotic power cords. Just proper passive filtering that actually works. Your transformers will thank you with silence, and your system will thank you with better dynamics and a blacker background.
