Synergistic Research Purple UEF Duplex - receptacle

lordmelton - 

Thanks for responding to my post and offering a recommendation. I’ve never heard of Oyaide R1, but will look into them before purchasing a hifi receptacle. Regarding the new SR Purple receptacle, SR states the technology behind the receptacle is based on the following “The Purple Duplex has an entirely new mechanical and material formulation selected during Double-Blind Testing, where Synergistic Research compared different duplex designs, choosing the one that sounded best. SR then added brand new UEF Tech, first developed for the new SRX cable loom, and Purple fuses for a lower noise floor with enhanced soundstage scale and realism. SR then applied the Purple Fuse’s Long Duration, High Voltage Conditioning Process. Hence, the new Purple Duplex shares the same house sound of high resolution with rich musicality as the Purple Fuses. Lastly, SR went with a floating ground design so that noise from your wall junction box is isolated from your system: the net result is the highest resolution and most musical duplex in Synergistic Research history.”

The question whether to use SR or QSA fuses, I believe, should be based on individual preference and which brand fits their system the best. My system is natural and neutral, leaning to the warm side, so the QSA fuses are a great match for my system. The fuses add more detail to my system. I have to say, the Yellow was a little brighter than I prefer but the Violet kept detail and removed the harshness. Also, I demo’d the SR Purple fuses and liked them but they were a little too warm for my system and I lost a lot of detail. I think the Purple is a great fuse but just didn’t match my system as well as the QSA fuse. What concerns me about the Purple, is how sensitive they are and SR recommends going up one rating above manufacturers’ recommendation. I have read many QSA forums and posts and none of them have stated QSA fuse are sensitive or have blown (not saying none of them have not blown). 

I do agree, $1,000s on a fuse is a little silly, but I am a believer that audiophile fuses make a huge difference in sound quality. I’m also interested in your statement regarding the possibility of SR creating a new fuse later this year. I also think the competition between SR and QSA is working in the audiophile’s advantage.

I hope you are well. I love my Atoll IN300 and think Atoll is an amazing hifi manufacturer currently flying under the radar. The IN300 is a very warm sounding solid state integrated amplifier. The sonic character is tube-like but with greater detail. It does an amazing job pushing high demanding speakers. I have a pair of ADS L1590II that have been completely refurbished by Richard So. They sound amazing. 

I thought the QSA Yellow sounded a little bright and am glad I moved up to the Violet. I think you will be very impressed with the SR Purple for the Atoll IN200 IEC. I like the Purple but I read SR recommends going up one rating above the manufacturer’s stock fuse. Also, Tweek Geek (where I buy my QSA fuses) allows you to receive full price on your current QSA fuse if you upgrade within six months. I agree with Willgolf and believe fuses can have the same sonic improvement as cables or any other tweak. I truly believe these fuses have taken my setup to the next level and I’m now getting the most out of my system. 

The Atoll IN300 takes a 10am/5x20/slow blow. 

Keep searching for the sound.

Thanks for the suggestions. Have you tried any of the QSA fuses to compare to the Power House Zero 2 Extreme fuses. I’m very interest to know which QSA fuse (color) I can compare it to. Thanks again for your suggestions.

Thanks so much for your review of the Purple duplex. Can I ask if you are using a power conditioner, and if so, what kind? Also, do you think there is is break in period? I bet there is and if you would be so kind to let us know if the sound improves over the next few days. I’m guessing it will really sound great after 100 hours

Thanks again and keep posting.

Thanks for the FYI regarding how to notify a person if I reply to their post. Your Furman is a very nice conditioner. I’m using a Audioquest Niagara 1200 which is not too bad but I’d like to step up. It’s awesome that the duplex corrected your loss of midrange after you applied High Fidelity Cables NPS-Q45t to all of your contacts. I would have been a little worried but I’m probably not as patient as you are (my wife reminds of that all the time…lol. 

I’m also wondering if the duplex sounds any different today than it did when you wrote your last post.
