Summary:
Fair enough, this cable is not recommended for people seeking the best base performance. But it works wonder for me given the small room size. It opens up the music and produces tremendous clarity to vocal musics. Unless your system already suffers from bright sound, it's worth giving this cable a try. Although this cable is not flexible, I can tell you that it's tough!!! Try bending it and you will know what I'm talking about.

Summary:
Bought the Super Flatline Gold MKII Biwire to replace my UltraLinK Ambiance cables for new Mission M74 speakers which can be biwired. After break-in period, the difference was noticeable. The highs (cymbals), the midrange and Ray Brown's Bass are just simply awesome! These cables are so fast and revealing that you should only hook them up to a good system, not necessarily an expensive one. If your source is bright (usually entry level gear), stay away. The brightness and shrillness will only be accentuated.
My cables are hooked up to 50 W/ch Audio Refinement (YBA) The Complete integrated amp and a Denon 2580/MSB Linc DAC combo at the other end. All bought used.
I can now hear new things in almost every recording I listen to. Now, time to sit back and enjoy the music.

Strengths:
Tight fitting banana plugs. Good connection. Pristine highs, good midrange, clean tight bass. Wide,deep soundstage on good recordings.

Weaknesses:
Handle with care.
Not for MAWKs (Married audiophile with Kids)

Summary:
I found an unused 5 meter pair on eBay and decided to give them a try. Though I hadn't read any of the reviews the recommendation of the fine folks at Madisound was enough to peak my interest. I figured that the speaker cables were one of the more cost effective upgrades I could make at the time.
When they arrived and I examined them I was immediately impressed with the surface contact area of their banana plug design. I proceeded to roll them out on the floor of my studio and admire my eBay bargain. The length was overcut so that 5m would be the working length after the gentle bends necessary for connection. The striking nature of a "cable" this flat is an odd bit of visual candy when you first see them.
Since my current speakers are not configured for Bi-wireing I used a pair of dual banana adapters so as to utilize both runs. I carefully laid the runs from the amp to the speakers and took one last listen to the old bullitproof buddies for the sense of immediate comparison. Then after cleaning all the contact surfaces I plugged in the Nordosts and settled into the critical sweet spot in my listening area. As I pressed the power button on the remote and the telltale LED changes from red to blue on the Krell the relay seems to take longer than usual, like Christmas morning when you're a kid. Then I press the play button.......
Diana Krall is sitting right in front of me, the transparent airy openess is stunning. I noticed that the bass is somewhat dampened compared to the old MC but this is not even a remote consideration. I switch to Hancocks' New Standard and hear nuances for the very first time oooooooooo. Neighbors, let's see. Adjust the subwoofer and put on a well mastered Carmina Burana and head straight to O Fortuna.
The Krell smiles as I punch up the volume control.....
Windows bow,the mailslot door goes horizontal and a few recent memories relocate. I can hear the size of the hall and the texture of the wall coverings. Neumanns separate themselves from Crown PZM supplimentals. Cymbals crash and shimmer. Tympani resonance is palpable and you can pick out the individuals in the chorus. I sit into the wee hours of the morning remeeting Miles,Jimi,Horowitz,Morrison (Jim&Van),Brand X,Weather Report and any other well recorded & engineered CDs that I remember I have. Over the next two weeks dramatic improvemant is evident and the initial bass frequency rolloff I noticed has blossomed into tight realism.

Bottom Line:
A Tactile Sense of Speed.
Beautiful Midrange, Highrange transparency.
Excellent Value, even at retail.
Highly Krell Complimentary.
Noticeable and Rewarding Break In Period.
Plus/Minus Flexibility Characteristics.
The Fine Folks at Madisound Like 'em.
Beats The Hell Out of Oversized Zip Cord!

Summary:
I had never believed that speaker cables made a difference until I started using these. Before with the monsters, my system sounded bright, fatiguing and on complex passages, it was muddy. Now it is clear and clean. My speakers sound the way they did at the dealer showroom! Gladiator soundtrack sounds fabulous, and so does everything else. I guess what it comes down to is that these speaker cables match perfectly with my system - they really brought out the detail in my system without being fatiguing.

Summary:
Having moved from AQ Midnight to this cable, I am impressed by the speed of this cable, though it is pretty clear to me that if your system is on the bright side, or your speakers are deficient in the low end, these cables won't do you any favors. The AQ Midnight, for instance, has a fatter bass. This can be great with some speakers, and with other, makes the speakers subjectively slower. Which brings me to a great strength of these cables- speed. If your system doesn't need a fat low end sort of cable, this cable is a fine cable. By the way, I am using this cable, bi-wired, with a pair of Revels.

Strengths:
Great sound- easy to run under a run

Weaknesses:
not all that flexible
