My Purple Fuse blew after only a few weeks. It uses the same Large, Slow 2A as the previous Orange and Blue fuses, which had no issues. I have advised the retailer and expect they will replace them, but what comfort do I have the next one will repeat? And I really thought the Purple was a major advance.  Neal

It’s interesting that I have only had problems with SR fuses and not any other standard fuse. They were all slow blow and even rated at two levels above the standard. My preamp manufacture cautioned about using a higher rated fuse and I didn’t want to get into a warranty dispute in case I had a problem.

Guys,

Synergistic has been quick to respond and replaced any of the fuses I popped at no charge and were willling to work with me to analyze posssible causes. My solution was easy. I turn my Carey SLP-05 preamp on first and then the power supply. The problem we all seem to be having is the current rush when we turn the power supply on. It is apparently a bigger issue with tube equipment. Also our gear could have weakened caps? Since I have replaced all my gear with Orange and now some purple fuses the music has become more real and musical. Improved imaging and detail, etc. The purple are even better. You do have to have good equipment to here major improvements and decent hearing as well. I replaced the fuses on my othe system in FL with the orange fuses but the improvements were not as dramatic. Good equipment there too, but not like my main system here in Chicago. I still wonder whey the cheap fuses never popped?

Glad you got yours figured out, Greg

I had a post last year where I tried the SR Blue in an integrated amp and it blew upon first power up.  The dealer recommended going to a higher-rated but Audio Research did not condone nor recommend this.  There was no problem whatsoever with that amp and this only occurred with the SR fuse.

The current ORANGE30 sale had me considering another go as I have changed electronics to different ARC models now with separates.

I talked to another dealer today, nice lady out in CA, and she said many customers up the values but nonetheless if I want to give it another go at the mfg ratings they are happy to sell and give a full refund if they pop.  This frustrates me that the problem even exists.  Spending $110 each at this point in the game is meaningless....I really wish I could comfortably try them out to let my ears decide if anything happens....oh well.

It's a dilemna for sure,

They really do sound better with good gear. Synergistic told me the cheaper fuses are not very accurate on their rated values so they could be significantly higher than their rating. If that's the case the manufacturers would have to be careful not to rate their recommended values as high.  Moving to a higher amp rating is  Synergistics normal suggestion and they say their amp ratings are very accurate. It worked for me and the technician at Cary was OK with a small jump in amp rating. I called first just to clarify things.

God luck

Greg
