Strength:
Warm, Detailed, Soundstages well, Accurate
Weakness:
Does not work well with all equipment Although I have owned the Pro 9s for quite awhile, I figured that it was time to write a review on my observations. During this time period, I have changed quite a few pieces of equipment in my system, and what I have discovered is that the Pro 9s do not work well with all equipment. At one point, I had the Pro 9s hooked up to an Adcom GTP600 processor, and the wire sounded great and made the Adcom sound warm and lush. Recently, I upgraded my processor to a Tag Mclaren AV32R which is already a warm sounding piece of equipment and the sound became so warm that the same wire became very compressed. On my center channel, I replaced another warm sounding cable with Pure Silver Sound Sextets, and things sound very detailed and lush on the Tag Mclaren but it did not work well with either copper wire used with the processor except with the TMC Yellow Label Interconnects. In purchasing cables for your system, you have to really understand the characteristics of your equipment or you can easily ruin a high resolution system with incompatible wires. Is the wire the problem, no but not all wires work with every system. If your system is on the bright side, add a set of Pro 9s and you will have a wonderful lush sounding and accurate system. However, if most of your components are warm be carefull with the Pro 9 it may make your components sound congested. Make no mistake the Pro 9 is a great warm sounding copper wire and will do wonders for many systems, just know your eqiupment before purchasing.

Listen to these cables before buying anything else, regardless of price. I don't think there's anything better on the market. |

The product name is actually Harmonic Technology, but it seems one can't correct ones mistakes once posted. These cables are an absolute steal at the prices asked by JimWang and Robert Lee. In my system they out performed cables like SPM, Siltech, Nirvana SL and Transparent Ultra. These cables opened my system up like nothing else. They just sounded right. The connectors are also excellent locking types I find better than WBT. Do yourself a favor and audition these cables before buying those kilobuck wires, you just might save yourself enough money to go on a little vacation. Or to buy lots of software. Don't take my word for it, listen and judge for yourself. Their website can be found at Harmonictech.com. |

I just wired my whole system with Harmonic Technology cables. I have the Pro-Silway between amp and pre, the Truth-Link between CD and pre, and Pro-9 Plus Bi-wire speaker cable and Pro-AC11 CL-3 power cords. I've had this stuff less than a week and so far I'm very impressed, and things can only get better. Just prior to buying the HT cables I had been trying out JPS Labs Superconductors. I had my whole system wired with their stuff as well, except no power cords. The JPS cables added a kind of interesting 3D effect but there was a dramatic loss of detail from my original XLO cable. After 2 or 3 weeks of listening while the cable broke in I found the JPS Labs growing more irritating and I promptly returned them. They were an obvious missmatch for my system. I didn't try that many cables in my system but I did do a lot of research and that's how I stumbled across Harmonic Technolgies. These cables have transformed my system and made the music flow so fluidly with incredible depth and detail that the component change I was considering is not even an option any more. |

I make it a practice to never purchase replacement audio equipment until I get a SIGNIFICANT improvement in performance. By this, I don't just mean discernable (let alone simply measureable), I mean a jump in quality so obvious that I would be reluctant to give up the new piece and return to the old stuff. For this reason I still use a McIntosh Amp that's about 12 years old, etc. I've been using some old Monster cable for even longer than that, since none ofthe new stuff made that much of a diference in my system -- until now. When I read about the Harmonic Technology patent, the theory made sense to me. I decided to try out a pair, under the stipulation that I could return the new cables if I didn't agree they were a significant improvement. I had a little hassle with HT overf spade size, and had to return them for a fix. But when I finally got the HT's hooked up, the sonic performance was IMMEDIATELY, SHOCKINGLY and OBVIOUSLY GREAT. Case closed. I decided to keep them within about 60 seconds and I can't get over how great my system sounds now ( after 3 weeks). I highly recommend that you try these one-of-a-kind technology speaker cables, and judge for yourself. I'm convinced. Rating: 5++++ |

I totally agree with Bill B. about the HT cables in response to Len claiming a 50% loss of output. The HT Truth-Links replaced Tara Master Gen 2 and the cheapest Audiodyne silver cables and there was absolutely no loss of output. If anything there was more output due to increased tranparency and bass. The treble is all there. If anything they were somewhat brighter than the excellent Audiodyne's. There must be something wrong with Len's layout. I have tested many cables and unless there hooked improperly there is no output loss only different sounding output. I have the 11 guage HT speaker cable for my midrange cable and was immediately impressed with their tranparency. The HT Truth-links are at least as good as any I've had in my complicated (tri-wired, bi-amped,5 interconnects), exotic tube system. |

I have audit the Pro-Silway, TruthLink and the Pro-9. I have to admit that they are good cable at the price they are commanding. But they are far from the best. In fact, I agree with Mr Leonard saying that the cable is not musical and I feel that the cable is dry and boring. No doubt that it sound detail and dynamic. This is some form of false information to your ear cos' there is emphasis over the upper treble and they have no 'air' or extension excluding the silway. The silway is fine but it is again dry sounding and pretty lean in sound (good for warm tube amp). Overall, all the cables are not as exciting as other manufacturer. For Mr RIVA, the silway is far better then the Truthlink.But careful audition is required as it may made your system dry and boring. |

To Sam B. and WP, who responded to my post of March 31, these words of clarification. The pre/amp connected to a source with Tara Decade interconnect produced a volume that was represented by a digital value on the pre/amp, e.g. a "20". To match that volume using the HT Truth-Link interconnect for the same musical material, I had to set the volume to a value of 30-35. This proved necessary on every kind of material (music). Others present in the room specifically to hear auditioning of the HT cables noticed and remarked about this uptake in gain to match volumes. Same result, i.e., higher value to match volume, was needed with XLO reference interconnect which, interestingly enough, replicates many of the HT's sonic effects. Audition a Decade interconnect for comparison to get the picture. |

Just a collection of our personal experiences after trying out over in Singapore as opposed to the previous Singaporean poster. |

I have not tried HT interconnects and the 5 star rating is for the Pro-9 Plus speaker cables which is the best speaker cables I've ever tried. In regards to the 50% loss output, it must either be a really thin conductor or a defective cable. But given the amount of possible audible differences in cables, I would lean toward the latter. I've only encountered <30% output with one interconnect and that is the Esoteric Musica 500. In any case, people seem to have different opinions on which interconnect model is better sounding. Have someone compared the Truth Link with the Pro-Silway? |
