Product Description

Tweek Geek Bybee Dark Matter AC Adapter

Supercharged Bybee AC Filtering with High Fidelity Wave Guides 


All of the Tweek Geek Bybee Adapters offer power conditioning like no other conditioner on the market. Nothing addresses noise like the Bybee Purifiers do. They do not limit or slow current delivery like transformers can, the do not have the negative effects of capacitors, and they take care of noise that no other electircal device can or does.


Dark Matter - The Conditioner For Those Who Don't Like Power Conditioning

The Tweek Geek Bybee Dark Matter AC adapter incorporates what we believe to be the ultimate in non-current limiting AC purification/filtration/conditioning available today. We have researched and chosen the finest materials and parts and put them together in what is our first series of Dark Matter products. This is a statement product which we manufacture in house. As such, we are selling them direct to consumer in order to keep retail pricing down.

The Dark Matter AC Adapter, like the other Tweek Geek Bybee Adapters, are a gorgeous, aluminum end capped carbon fiber tube with a high quality Furutech rhodium copper iec inlet on one end, and a Furutech IEC plug on the other. In between there is a carbon fiber tube that contains the latest Supercharged AC Purifiers from Jack Bybee, AC Wave Guides from High Fidelity Cables, and our proprietary ground filter.  It is designed to go in-between your audio component's power cord and the component, placing the conditioning elements as close to your audio component as possible. This provides immediate, direct and NON CURRENT LIMITING filtering of your audio component's incoming AC for maximum effectiveness. There are no capacitors, no resistors, nothing to impede the flow of current flowing to the component.

A Power Conditioner For Each Component, Right At The Point Of AC Entry

Imagine, a power conditioner for each individual component in your system. One with no current limitations or additional switches and LED's to add extraneous noise. One that offers the finest, best noise reduction for each individual component in your system. One that allows you to use whatever power cord works best with your system without changing the tone or characteristics of the cord. If you are looking for the best AC filtering for your top performing audio component, you've found it. We challenge you to try it and say we are wrong!


IEC inlet & plug - The Tweek Geek Bybee Dark Matter AC Adapter uses Furutech's NCF (Nano Crystal Formula) FI-50NCF and FI-06 NCF. They feature rhodium plated Pure Alpha copper connectors, and EMI RFI absorbing materials in the body. Folks, these are the absolute quietest, best sounding connectors we have ever used. They are not subtle!

The male IEC features Furutech's Pure Transmission FI-50 Piezo Ceramic series connector body and housing. Both the male and female IEC's are coated/embedded with nano particles that are highly effective at passively reducing EMI and RFI.

furutech fp-s032nWire - We use Furutech FP-S032N Alpha Nano OFC Technology power cable. It's only 8" of wire, but we wanted to use the best possible wire to compliment the low noise factor of the NCF iec, plugs, and of course the Bybee products inside the adapter. Alpha Nano-OFC is one of the best conductors Furutech engineers have found for sound reproduction. The new technology used in the highly specialized manufacturing process of this ultra-high performance power cable combines Furutech's world renowned Alpha conductors with Furutech's extremely effective signal transmission enhancer, Nano Liquid.

We also make power cords out of this wire in combination with the Furutech NCF plug and iec connectors. The sound is super quiet, dynamic, rich and layered. The bass control is un-believable with this cord.

Body of The Dark Matter - We machine our own aluminum end caps for the carbon fiber tube we use to contain the Supercharged AC Bybee Purifiers and our proprietary ground filter. This is expensive and time consuming, but very worth it. It gives the adapter a very elegant, finished look.

Bybee SE AC Purifiers - We incorporate the Bybee SE AC Purifiers on the hot and neutral legs of the AC. No other electrical component used for AC filtering can do what the Bybee Purifiers do. They do not impede current flow, or have any of the negative side effects of capacitors, chokes, or transformers. They simply remove noise that other devices cannot, in a way that they do not, and the sonic results are evident within seconds of inserting these devices on the hot and neutral legs of the AC.

High Fidelity Wave Guides - The High Fidelity Wave Guides utilize the same magnetic conduction technology that is used in their line of extraordinary audio and power cables. They work to enhance the flow of electricity, and as a result they reduce noise dramatically.  We are the first to combine both Bybee and High Fidelity technologies into a single product, and the result is really stunning. For those that demand the best, without compromise, this is the AC conditioning product for you.



Furutech fi-06 ncfWhere to use the Tweek Geek Bybee Dark Matter AC adapter

The Tweek Geek Bybee Dark Matter AC Adapter can be used on any audio component that accepts aftermarket power cords. Simply plug the power cord into the back of the iec inlet, then plug the Furutech IEC plug into the back of your component. We recommend  you start at  your source components first, then your preamp, then your amplifier(s).

For those of you concerned with losing dynamics from a standard power conditioner, the Tweek Geek Bybee Dark Matter AC Adapter will allow you to filter and improve your audio component's incoming AC, without taking a chance on losing dynamics through the common filters used in most AC conditioners. We don't use common filters...

What can I expect to hear?

More textures in the music, more decay, air, space, dynamics, musicality. Any more audiophile buzzwords? Yes! Way better bass reproduction with more finesse, tunefullness and impact. What is most amazing is how you can have more body, and more transparency with less fatigue factor. So often you sacrifice body for resolution, or gains in transparency for loss of bass weight or midrange body. What the AC adapters do is nothing short of an audiophile miracle. You achieve an organic, non-electronic flow and ease to the music. You have midrange richness, fullness along with bass weight and slam. Last, you have incredible gains in low-level resolution that give you that wrap-around SE imaging. It will take ANY power cord, no matter how good, and make it better. We guarantee it. Why not try one for yourself with our In-Home Audition Program?


How Long Does it Take To Make One?

These are hand-made, custom machined and painstakingly hand assembled products made in Colorado. It will take approximately 2-3 weeks from date of order until your Dark Matter AC adapter is delivered.

Is there a Warranty?

Yes. We warranty the adapter to be free from defects for 5 years. This does not cover abuse or misuse of the product such as excessive, repeated twisting of the cable.

Is There a 30-Day Money Back Guarantee?
