Planus AG2 Interconnect Cable

Along with our introduction of the Planus III AG speaker cable, we have developed a companion interconnect that allows one to experience the full capabilities of that speaker cable. The new interconnect is Planus AG2. Planus AG2 has a revised geometry that allows more of the music to come through unscathed. Planus AG2 takes the music to a whole new level of detail and refinement.

Planus AG2 is more detailed while also being smoother. With AG2 you will not experience the nasty peaks or sheens normally associated with silver. Instead you will hear greater detail with a smoother presentation. The interconnects remove another layer of haze allowing you to hear more clearly into the performance.

As one listening panel member (who currently uses the Planus AG1) said, “Fantastic IC. I am listening to things I have listened to so many times and things are being revealed I never heard before. None of the "sheen" you guys used to sometimes ascribe to AG1. You have a real winner.”

Instruments/voices sound more natural. The transient response of the wires allows one to better hear the initial attack with a more natural decay. Also one can better hear the expressiveness of the musicians. These are subtle changes compared to Planus AG1, but are very noticeable.


MG Audio Design, LLC is now offering, as a companion to its award winning speaker wires, a series of interconnects - the Planus interconnects. The Planus interconnect has the same sonic virtues of the speaker wire -it is transparent, detailed, neutral, and very musical.

Consistent with our design philosophy, we did not develop this wire to have a house “sound.” Rather, we focused on minimizing capacitive, inductive and skin effects that inevitably color the sound of all wires. The minimization of these factors is especially critical with low-level signals where loss of high frequency information and phase response is magnified. The design is based on physics and good engineering practice, not voodoo. The result of this design is that you can hear more clearly into the musical performance, catch details you have never heard before, and better capture the emotional expression of the artist(s).

We have three different versions of the Planus interconnects- the Planus CU2 (Copper), the Planus AG1 (Silver), and Planus AG2 (Silver). Planus CU2 has been cryogenically treated to maximize signal flow through the wire. The cryogenic treatment allows the CU2 version’s performance to be about 90% of the performance of the AG1 version. The CU2 version is an excellent wire, among the best on the market today; however, when compared to its more expensive big brothers, it lacks a certain “magic” that is present with the AG1 and AG2 versions. The CU2 has more warmth in the upper bass and lower midrange compared to the AG versions, but lacks the last bit of air, detail, and speed that make the AG so stunning. Our latest interconnect, AG2, redefines state-of-the-art in terms of musicality, transparency, detail, and soundstaging.

We are introducing a Series 2 version for our balanced interconnects. At the suggestion of one of our friends (Bascom King to name drop), we put an RF filter on the end of our balanced AG2 interconnects. We had thought about this previously, but were concerned with how the increased capacitance would affect the overall performance of the wires. As it turns out, we should not have worried. Another veil was lifted from the music. We tried this with single ended cables and did not find much, if any, improvement. Therefore, we will be offering the Series 2 as our standard for AG2 balanced interconnects and a $50 option for AG1 and CU2 balanced interconnects. We will retrofit older balanced interconnects, but you will lose an inch of length on the cable because we have to re-terminate them. The cost to retrofit will be $250.

No one wire can be the “best” wire for all systems and ours is no exception. While we have put these in a number of different high-end systems and they worked very well in each, there may be times where the wire is not well matched with the voicing of the system. All Planus wires are very revealing, not boring or polite. Because of the potential to not work well in a particular system, we offer a 30-day money back return for standard length wires sent back in saleable condition.

All Planus interconnects are available with a balanced or single ended geometry. The single ended versions use a locking RCA. We will make custom lengths for these interconnects; however, we will only make single ended wires a maximum of 1.5 meters long because of the potential for high frequency interferencee.

All Planus wires are unshielded so their physical placement within a system is critical for best performance. If you must cross other wires, especially power cords, be sure to cross them at a 90-degree angle. Running them parallel to other cords can cause signal degradation and introduce the potential for hum.

The price/performance of all of our wires is exceptional. They have easily outperformed well-regarded wires costing ten times as much as the Planus wires. Please contact us if you have any questions.

Also, your best results will be achieved by using Planus interconnects with Planus speaker wire. The speaker wire is based on a geometry similar to the interconnect and has very similar sonic virtues. Together, these can transform a system.
