The main power supply has a fundamental impact on the audio signal when passing through the system, from the power supply to the amplifier. General residential main power supply is easily susceptible to interference caused by various problems and AC waveform distorted before reaching each component. This creates noise in the audio signal and decreases sound quality. With more electrical appliances used in homes, conditions continue to worse Review: Cleanup sound - I got one of this for the amp at first, and like the result. Then got another one for the source equipments. They clean up the power and make sound more transparent. Review: 2 Days from now, you will be mainlining the purest audiophile grade sound imaginable! - I did not perceive there to be any problems with the electricity in my system, I purchased the DC Blocker in the hopes of better sound. As I was plugging it in, I was having skeptical thoughts, figuring that it would likely go back. I hit the power button on the amp and was absolutely ShOcKeD! The improvement in sound quality jumped straight out at me. It was like putting a new battery in your Accord and all of sudden you have a 700hp V-12 Ferrari! All aspects of the audio are improved. The biggest difference is in the mids. Vocals are more holographic and real. Hugh increase in separation, clarity, layering, etc. Insert the whole audiophile lexicon because you name it, it was doing it. I skimmed my way through around 500 songs and counting. I have tested this DC Blocker with 2 different amps, one 240 volt and one running 120v and both were vastly improved (audiolab 6000a and Rotel A11 Tribute). I like both amps, but the 6000a is definitely superior in terms of straight up sound quality -mainly in bass articulation. This DC blocker will do the most good on amps. I've tried it on partnering equipment and performance seemed a bit enhanced but I don't know if I could tell in a blind A/B test. Results will be most dramatic on amps. I would guess that it will produce the best results on mid and high level equipment because crappy power is the only thing left holding them back. It's output plug is IEC (most amps use this input) so you can't use it with any old plug without an adapter. It is limited in it's output to 300 watts although the fuse is for 4 amps so it would likely handle a bit more. Powering a receiver would likely work out great as long as you don't crank it on 8 channels. This will not feed a whole 12 outlet power strip but there is an small IEC power strip available here on desertcart and you could likely power an amp, dac and a disc player at the same time. It is a little disheartening to realize how badly our gear is being served by the terrible quality of our electrical grid. Your gear is way better than you think it is! Even if you don't think you have a problem with your power, you must try this audiolab DC Blocker. This little device was a bigger upgrade than buying new speakers and cost a pittance in audiophile terms. To the naysayers and snake oil proclaimers, there is much to be skeptical about in audio, but I challenge you to send this little guy back. I own two of these. Some day, one of them will go to my heirs. The other will be placed under my head and buried with me for holographic sound in the afterlife. Let's face it, hell likely has dc on the mains. ## Features - Remove DC from AC power - Reduces transformer hum - Reduces RF interference - Improve the performance of your audio components ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097WMR2T1 | | Brand | Audiolab | | Color | Black | | Connector Type | Barrel Connector | | Connector Type Used on Cable | Barrel Connector | | Customer Reviews | 4.0 out of 5 stars 49 Your Review | | Enclosure Material | Metal | | Form Factor | Compact box-like design | | Input Voltage | 120 Volts | | Manufacturer | Audiolab | | Material | Metal | | Maximum Power | 600 Watts | | Mfr Part Number | DCBLOCKBK | | Model Number | DCBLOCKBK | | Output Voltage | 120 Volts | | Output Wattage | 600 Watts | | Specification Met | CE, RCM, RoHS | | UPC | 840117508255 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Audiolab - **Color:** Black - **Connector Type:** Barrel Connector - **Input Voltage:** 120 Volts - **Material:** Metal ## Images ![Audiolab DC Block Audio Grade Main Filter & DC Blocker (Black) - Image 1](https://m.media-amazon.com/images/I/619XA2e31+L.jpg) ![Audiolab DC Block Audio Grade Main Filter & DC Blocker (Black) - Image 2](https://m.media-amazon.com/images/I/61Ph7bYxsPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cleanup sound *by J***F on January 16, 2025* I got one of this for the amp at first, and like the result.

Penny. *by D***N on June 20, 2022* I treated myself to a very high end Woo Audio Headphone Amp with some very nice headphones and, well, this rig reveals EVERYTHING. Bad recordings, microphonic tubes, and bad power. Based on my sitting position, I had to plug the Woo into one of our standard outlets and got a LOT of hum. I was very disappointed. However, when I plugged the Woo into the PS Audio P5 power conditioner that feeds my main hifi system and is connected to a dedicated power line from the main breaker box and the Woo was dead silent without any hum, I knew I had two options: a very long cord from the P5 to the Woo or another power conditioner. Then I came across this little magic box and based on the price I figured there is no risk trying it. I just plugged it in for the first time and wow, all hum is gone. I turned on all troublesome power users in the house (dimmers, TV, smart devices, towel warmer, etc.) and still, the Woo is dead silent when fed by the Audiolab. I cannot recommend this little black or silver box highly enough. As the title says....worth every penny and honestly, then some. For comparison, the PS Audio P5 ran $5k when new. $129 for the Audiolab is an absolute steal. ## Frequently Bought Together - Audiolab DC Block Audio Grade Mains Filter & Direct Current Blocker (Black) - zdyCGTime 3 Prong USA C14 to NEMA 5-15R Plug Power Adapter for Standard Computer Power Adapter 15A/125V (IG-320) (NEMA 5-15R to IEC 60320-C14)(2 Pack) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/724849704-audiolab-dc-block-audio-grade-main-filter-and-dc-blocker](https://www.desertcart.kg/products/724849704-audiolab-dc-block-audio-grade-main-filter-and-dc-blocker) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-06*
