New Silver/Palladium Opera cable in house!
This is my first time dealing with Arctic Cables and my entire experience was absolutely stellar! Val was the consummate professional and all of my emails were promptly and expertly answered. It was a pleasure doing business with them.
The Opera is being used with my Focal Utopia headphones, HeadAmp GSX MK2, with source duties provided by one of my 2 channel systems streamers - the uber Linn Klimax DS (google if you are unfamiliar).
I have been a member of HeadFi since 2003 and spent 2006-2017 out of headphones and strictly with my 2 channel system. When I returned I wanted to go straight to the totl and during the 2017/18 time frame it was all Utopia…Utopia…Utopia. Together with my Focal acquisition Sony had just released the Signature Series Z1R and WM1Z which I also purchased for mobile/closed back use. Kimber Kable had recently introduced their Axios line of headphone cables and a set was purchased for both the Utopia and Z1R. Both cables have remained my primary drivers up until now.
The difference in performance between the Kimber Axios and Opera cable is quite dramatic with the Utopias. The bass heavy sound of the Axios has been removed and replaced with a tighter and more tuneful bass - the bloated sound is now gone. This has allowed more details to come through with increased air and separation - all resulting in a more tuneful and engaging presentation. I definitely think silver cables will be a fixture in my systems going forward. Together with the Opera cable my Utopias have started to venture into Stax 009S performance and are giving those cans a serious run for the money.
My next step is to decide whether or not I want Arctic to fabricate a set of adapters to enable me to use the Opera with my Z1R - or purchase a second Arctic cable for the Sony. Tough decisions to make!
PS - build quality? Impeccable!
PSS - I went with the upgrade to the Furutech XLR connector over the standard Neutrik. So much nicer.

Roy was extremely accommodating and agreed to help make a custom order for a palladium wire speaker post/tap adaptor.
Furutech female adaptor and Furutech banana plugs, with custom fabricated fittings to mark out the R and L channels. He had to specially order in the banana plugs, and he told me his crew broke 6 drill bits trying to fabricate the plug fittings for me.. Lol!
Excellent workmanship as usual!
Oh I forgot to tell him im not a big fan of CF.. No biggie. Nothing some matte tape can't fix..!

OK- this cable is fantastic and an audible improvement over the stock Utopia 2021 cables!
I bought it for use with my Hugo 2+2Go and Astell&Kern SP2000 but will be ordering a 4 pin XLR adapter for use with the Focal Arche as well.

Currently at 60 hours burn in, and AC/DC's Back in Black has gone all the way from "ho-hum 100% meh" to "realistic in a fun way". I was convinced that my Hugo 2 (or my Aeon 2 Closed) was simply not suited to AC/DC, even though other hard rock sounded great, like Van Halen. With the Vivo cable, that was the case. But with this Signum +, AC/DC sounds the best I've ever heard! What is so awesome is that there is more detail and realism, but also more musicality, more fun at the same time! And Van Halen still sounds good, better than on the Vivo. The soundstage seems to have evolved in a general sense, without losing any positive traits that I can detect. Loving it so far!

Alright! I made it to 150 hours burn in on my Signum Plus! Took me about two weeks, cause I prefer to give my headphone rest breaks rather than going 24/7, even though it may not be necessary. But now it seems the bass and mids have fully bloomed, and the whole sound has become more refined and pleasant. My Aeon 2 Closed almost sounds like a whole new headphone, and I bet if I had been using the basic stock cable rather than the premium Vivo cable, it absolutely would sound like a whole new headphone. Compared to the Vivo, detail has increased across the whole spectrum, treble and bass are both better extended, every aspect of the soundstage has improved a bit, and everything sounds "nicer" or "more refined" in a way that words can't properly express. The most exciting thing to me about the Signum+ is that, due to the improvements in imaging/soundstage, many albums which I thought lacked the acoustic information necessary for interesting soundstaging are now presented in a fun, spatially varied, natural sounding 3d way. Two of my favorite albums, Back in Black by AC/DC and A Day Without Rain by Enya both sounded tragically boring to me with the Vivo cable. Detailed yes, "technically accurate" certainly, but just dead, lifeless in the soundstage department, a flat, mediocre image. The Signum + brings a little more detail, and still sounds natural and honest, but it presents certain recordings in a fundamentally more interesting, involving way that will have a MAJOR impact on how much of my music I really enjoy vs simply appreciate. I feel so sorry for people who don't believe cables make a difference. I seriously thought Enya just wasn't hifi worthy. Man was I wrong. Same exact cans/dac/amp/source, and this cable, by itself, made Enya good (at least from the perspective of a soundstage maniac like me).

My Fusion Series Cable arrived finally!! USPS had a horrible holiday season, but the Fusion is here. Here is the first photo I took, and it doesn't do this cable justice, super beautiful, and wonderful ergonomics. Also asked for an interconnect for the Romi Audio BX2 +.

Just received my Signum+ today and am listening right now. From the splitter to earcups is pretty tight, not loose at all. See the pics. Pretty good quality. Packaging is very impressive.
Fresh outbox, wow, significant! Dynamic, fine details, richness, probably toward 'bright' side. Will give it more break in time. Very confident it will 'mature' better. My system: HP All in One Pavilion --> WireWorld Starlight 8 USB --> SONY TA-ZH1ES (as DAC) --> Cardas Golden Ref RCA --> Woo Audio WA6 SE 2nd GEN + GEC U52.
Not quite an OMG effect as when I first rolled in GEC U52 rectifier to my WA6 SE 2nd GEN, but definitely impactful change. How long it takes to fully 'break in'? Any idea?

Finally received my Signum+ cables yesterday. Initial impression all very favorable. I can’t yet delineate the many good things that I hear since 24 hours is not enough time on ears to yield valid conclusions IMO. But I will state that the following characteristics have been noted thus far compared to the stock Stellia cable:
Strength, depth and impact of lower frequencies very noticeable
Provides a layered and transparent sound with smooth tone and precise image placement
Wide airy soundstage with more 3D illusion
Nice even frequency response and no more perceived “shoutiness” with the Stellia
Top end more extended without any grain
Very nice leading edge transients
Cosmetically attractive with excellent construction quality
After a week or so I should have a better handle on its long term performance. After that I will see how well it mates with my HE100se and my son’s Elear and T5p phones. So far very impressed and extremely satisfied.
BTW, most of my listening is being done with my MBPro running Roon core via USB to a Direct Stream DAC to Pass HPA-1 which unfortunately does not take advantage of the balanced capability of the cable (using a 2.5mm trrs female to 6.35mm male adapter). But I am also occasionally listening using balanced out on my A&K SR25.
