I've never bought one so cannot advice first hand, But I have read zillions of reviews and posts by people I trust their opinions. It would seem that this company "Monster" is held in low esteem by audio professionals. 
  I don't purchase cables that have  so called "gold" plating. I don't believe there's much real gold in there so I stick with whatever it is Switchcraft uses. I believe it's a nickle alloy. 
I have also come across Monster cables in places like Radio Shack so that tells me they are mass consumer oriented. They seem overpriced for the quality. So it would seem that the company is " Marketing" based and not at all about building what audio professionals ask for. 

Personally, I build my own cables, but I'm also good at soldering. Unless you're building a studio to compete with the big boys, and you would be ok building cables, don't bother with anything more than this:

Rapco Star-Quad spool (may cable is yellow) and Gold-plated Neutrik connectors. You will save yourself thousands and come out with excellent cables. I have several that are 50+ feet and they are super silent, even when strung right alongside of power cables. They're made mainly for TV studios. Be sure and wire all five conductors to the XLR plugs.

Monster and Mogami are embarrassingly over-priced. They are good cables (Mogami is better than Monster, imo), but they both use the same marketing technique: If you want the BEST, you will buy ours and pay our premium prices. They REALLY dig the "get what you pay for" analogy. But this is not unlike the $10,000 power cables you can get your hands on. They are likely the best, but this gets pretty subjective in nature, when compared to other areas you're better off spending time and money on. See my signature...  

For location work, I will use standard canare star-quad or redco snake cable.  Neutrik connectors are better for gripping the cable and are more durable by far over switchcraft, which fall apart easily with rough handling.  The one exception is the thin cables on snakes, where the neutrik chuck will not grip, and could cause the pins to pull out.  A little shrink wrap or electrical tape at the chuck can fix that.  I have noticed however, switchcraft connectors seem to be less prone to ground problems and possible hum introduced by microphone handling and poor grounding schemes. So it is nice to have a combination of both for different situations.  

For studio I would recommend the thin cables from Canare, Mogami, or Gepco for installed connections and standard cable for microphones.  The heavier cables are only necessary for areas where extra damage protection is needed.  It does nothing for the sound. 

Quad cables have higher capacitance than standard cables, but even at 1000 feet, the frequency drop is only about .1db at 20kHz.  So nothing to worry about.   I have never had problems with phantom power driving microphones at over 200ft of cable.  

I have several redco cables and I like them. I also have some really inexpensive cables from monoprice that works well too. I can't tell the difference in performance. I like them better than the overpriced cables hanging on the racks at music stores.

So as I posted earlier, I ordered from Redco, using the MIC-5 cable. It turns out that Redco did not have any of this cable in stock to complete my order. After a brief conversation with a representative from Redco named Mark, Redco has decided to substitute the Canare L-4E6S for the out of stock MIC-5 in an effort to complete and ship my order for an estimated arrival on Thursday of this week...same price. I spoke with Mark on Monday or Tuesday of this week. Redco's commitment to customer service is great and I am so happy with how they handled my order. If the cables are as good (and I am confident they will be) as their business model/customer service, then I believe I will be doing business with them from now on. I intend to build a studio space and will need to install permanent cables and wall plates and Redco will be supplier. Thank you Redco and thanks to all who led me in that direction. As a side note. I took the opportunity to look closer at the other offerings at Redco and wish I had done so before I placed my order with another company earlier. It turns out that Redco offers a lot of stuff and I did not know this when I placed my order for two Onstage SB9600. There pricing is very good. Now, in fairness to the other company, they have free shipping and a some other pluses, but Redco's price savings on one stand alone was $35.00. So don't just go to Redco for microphone cable...they have a lot more to offer. Oh, by the way...some of you know me from other forums and posts...and can attest to the fact that I don't work for Redco. I am just a guy starting out in an effort to record my own band and believe me if I was to get these cables and they were crap, I would report my finding to you immediately, but I am confident this will not be the case. I should be using these this weekend and will let you know my hands on opinions, thanks again.
