Review: Furutech TF-10A Pure Transmission Fuse Tweak

Category: Accessories

I purchased this fuse mainly as a cheap power upgrade for my Burson HA-160 since I was unable to use the upgraded power cable I purchased. I figured, for the amount of money to purchase a fuse, if the benefit was as good as others had stated, then at least it's worth a shot.

Before installing the fuse I played one of my more familiar discs (Sade-The Best of Sade) just to implant the overall sound paying close attention to image depth, soundstage width, details and tone. I then powered down the system, installed the Furutech fuse and powered back up. I waited a few minutes before listening, but was interested to see what the immediate changes (if any) would be. I will just say that the first impression was a night and day noticeable difference between the Furutech and the stock fuses. There was a clearly evident improvement in 3 dimensionality of images. A tad bit more extension to the higher frequencies, although very smooth and grain-free. Also, an additional punch to leading edges that were most noticeable in the beginning of words, such as words that begin with "b","d","f", etc. Even though you know the word the singer is singing, hearing them sound it out properly is nice and a trait you may not know you miss until you hear it more correctly reproduced. I was also impressed that the tone of the amp was allowed to remain fairly balanced throughout the spectrum as well.

I then let the amp/cdp run for an additional 24 hours and listened again for any changes that might have taken place. Unfortunately, the additional extension in the highs had settled, and were a bit rolled off in comparison to my initial experience, yet still a slight improvement over the stock fuse. I am pleased to say that the other improvements were still in place. The biggest area of gain for me was the 3 dimensional images. It truly makes the difference between hearing some music and actually being able to picture the instruments and singers. Soundstaging was plenty wide with good separation. When playing my favorite metal band Opeth, I could clearly hear the guitars, bass, keyboards, drums and vocals in their 3 dimensional glory even when all members were jamming along hard and heavy.

My next test was to use my other source...an iPod. The iPod is connected via the line out connection to rca's using Wireworld cable, so it's a pretty decent source believe it or don't. Yes, there was noticeable improvements even with the limited format of iTunes material. The biggest gain again would have to be the 3 dimensional images that helped to paint a more realistic image. Positive Feedback has a brief statement about the Furutech fuses in which they use the word organic. This word I feel is as good as any I would have chosen to describe them myself.

72 hours into use and the sound remains pretty much the same as after the first 24 hours. For the price of entry, I highly recommend. It has given me improvements comparable to a good aftermarket power cable, and I do mean a good one. I might have to get one for the Primo next.

Just following up on comments here.  I originally tested the Furutech fuse along with several other fuses a few years ago.  I came to the conclusion that the Furutech was the "fastest" fuse (i.e. all the instruments hit faster with more authority), but it seemed too "solid-state" sounding to me.

Years later, after playing with multiple types of power plugs, I have determined that the rhodium plated items from Furutech really take 250+ hours to fully burn in before they sound best.  In the first 100 hours you will have a natural roll-off of the high frequencies.  Bass can also be lean.  I think bass comes back after 100 hours, but between 100-200 hours the highs become really bright and harsh, causing everything else to sound harsh.  After 200+ hours, the rhodium finally starts to calm down and after 250+ hours they really start to open up and just sound absolutely phenomenal.  The resolution and strength and punch and bass power (the whole deal) is just awesome.

I have no problem with the brass instruments that gbmcleod said he didn't like.  Once it's burned it, it does everything perfectly.  I came back to this fuse after a long time listening to Isoclean and wanted more resolution.  The Isoclean's were great and very warm, but they did have as much high frequency resolution.  The Synergistic SR20 had resolution and were very fast, but they just didn't sound real (they were cold sounding to me).  I tried Synergistic RED, but it was just too soft (not enough resolution).  I didn't like Hi-Fi Tuning because I don't like the sonic signature of silver (it pushed the upper mids/highs and just didn't sound as real to me) - though many people like this.   After working through A/C power connectors and determining the rhodium copper alloy from Furutech was the best, I tried the Furutech fuses again.  I think many people just haven't given enough break-in time for these fuses.  I think the rhodium plated copper end-caps and the copper alloy conductor are the best materials to use.  Furutech puts a damping filler in the fuse to help with electrical resonance of the very thin fuse element (as akin to what Audio Magic does with LittleFuse fuses).
