Planus IV Speaker Cables
MG Audio Planus IV Speaker Cable
Planus IV resolves low-level detail even better than Planus III while also adding a palpable presence to the instruments and voices in the soundstage.
As the newest members of the Planus cable family, the Planus IV series of speaker cables brings a whole new level of performance to our wire line. Please read about Planus IV AG after reading the rest of this narrative.
Improved Low Level Resolution
Planus IV resolves low-level detail even better than Planus III while also adding a palpable presence to the instruments and voices in the soundstage. You get a better sense of being at the performance. Another veil has been lifted compared to our already incredibly transparent Planus III speaker cables; however, musicality has not been sacrificed – the Planus IV speaker cable is even smoother in its presentation. Planus IV has no nasty sheen or edge you typically find with most other “high resolution” cables, just a natural, balanced sound. With Planus IV wires, more of the subtleties in the performance flow through the system. You are able to hear more of the musicianship of the performer(s). You can more easily “get” what the musician is trying to portray.
The Planus IV series uses an even thinner and wider foil for the conductor than Planus III. It also uses a new PTFE (Teflon) tape formulation for the dielectric. While much of the enhanced performance of the wire can be attributed to the new geometry, some of the performance increase comes from the new dielectric we are using.
In terms audiophiles like to use, Planus IV does everything better than Planus III. The soundstage is wider, deeper and more three-dimensional. The dynamic shading is more evident, with more impact on dynamic passages. It better captures both the leading edge and decay of the fundamentals and overtones. One gets a better sense of pace and timing. The music comes from a blacker background and the retrieval of detail is just stunning -- without any glare or brightness.
With Planus IV one can better hear the complexity of bass in the music; the fundamentals and overtones are more accurately portrayed, giving them the proper weight and speed -- no bloat or tubbiness. The midrange is full with the proper balance between the lower midrange and the upper midrange. The upper frequencies are sweet and extended without any nasty edge or glare.
The differences between Planus IV and Planus III are not startling when you analyze them using the individual criteria discussed above. However, when taken as a whole, the Planus IV offers a whole new level of cable performance.
Planus IV uses copper foil as the conductor. Planus IV has is slightly warmer in the upper bass/lower midrange region giving the music a more organic quality. However, Planus IV does not have the resolving power of Planus IV AG. The difference in performance between the two is the difference one gets with silver vs copper. Silver has more high-end extension and better low-level retrieval. Copper is warmer and more organic sounding. Which one is better depends on the system and individual listening preferences. While generally the silver version is “better” in most systems, we recently tried both in a system with Soundlab speakers. In that system, the listening panel preferred the copper version of Planus IV. The stats already did a great job of resolving low-level detail so adding silver to the system did not enhance this part of the system’s performance. Also, the system was already slightly lean in the upper bass region and it became even leaner with the silver. The warmth of the copper was just what the stats needed. However, in all of the other systems we have tested, silver was the prefer cable if you did not consider the cost difference.
Is It Worth The Price Difference over Planus III?
Now, the big question on a lot of peoples’ minds – is Planus IV worth the price difference? If you are looking for performance versus cost, the answer is no. On a strictly bang-for-the-buck comparison, Planus III is clearly the superior wire and probably the best value in high end today. Planus IV (copper) offers substantial performance improvements over Planus III, but needs to be used in relatively high- resolution systems to show the full potential.
Handling of Planus 4 Speaker Cables
Please be aware that the Planus 4 speaker cables use very thin foils for the conductors which can be easily torn. Always handle these wires carefully and do not pull or twist on the terminations- you will rip them.
