Oyaide chose the 110Ω impedance for the AR-910
, thus the ideal value for a balanced interconnect. While we were in flip-flop mode with multiple interconnects, we did a tour with the Tunami Terzo XX V2 versus AR-910 as analog interconnects between PS Audio DSD DAC and preamp. In this case we had to hard-swap the cables at the DAC end as there is only one pair of XLR outputs available. Our conclusion was that the AR-910 in its analog capacity in an otherwise fully copper-wired environment introduced a slight brightness. This was mainly present with transients like cymbal crashes which moved more into the aural spotlight. While this was noticeable in most if not all studio recordings, the effect was not present with unadulterated live recordings. We might say that when limiters and compressors are involved, a cable can be of greater replay influence than with recordings that have large dynamic range. That was our lesson for the day. All throughout, we used the Tunami GPX V2 power cable terminated with bright Italian red P-046 and C-048 plugs, two Tunami GPX-R V2 terminated with what Oyaide calls Aspirin white P-004 and C-004 connectors and one Tunami GPX-V2 terminated with M1E and F1 connectors. All were thus terminated with male Schuko EU plugs which enable easy phase/polarity correction. The Schuko plugs in the Tunami series are equipped with a coloured polycarbonate cover whilst the contacts are beryllium copper plated with platinum/palladium. Differentiating the red and white connectors is the thickness of the plating.


Common to all these power cables is the 102 SCC conductor and black polyurethane outer sheath. Underneath that sheath sits a copper foil followed by a layer of carbon-infused PE and a sheath of polyolefine polymer that acts as a microwave absorber. Next a pure polyolefine layer sheathes each individual wire. There are 4 wires in total, two 102 SCC, one OFC copper for the ground wire and another OFC copper for the so-called drain. That’s quite a lot of poly material and layers. What we noticed when training the power cables? The black polyurethane sheath is quite rough. Two cables touching kind of stuck together. We managed to phase align all connections thanks to the Kemp Polarity Checker. As mentioned, the red-plugged GPX V2 was in charge of the MTS-6E power distribution block and the other three Tunami power cables served various masters throughout the test period. Except for the power distributor having an iron grip on the connectors to require some ‘persuasion’ to let go, plugging and unplugging was a cinch and the IEC connectors fit really well, a matter that is questionable with many other makes, even renowned ones.


As with all good power cords and especially a full loom, the sound factor derived from their employ was one of tranquility and rest. The most expensive cable had the M1E/F1 connectors where Oyaide’s standard beryllium copper, platinum and palladium recipe adds Delrin for the inner housing which covers the glass-filled PBT pin assembly before an aluminium alloy outer sleeve covers all. This is Oyaide’s top-of-bill (literally) Schuko connector. The IEC F1 female is its mate. While doing chores figuring out what the best combination of device and cable was, we came to the conclusion that the source gained the most from the M1E/F1 capped cable. In our case we found that the already not too shabby sounding PS Audio DSD DAC gained in performance when fed through this version of the Tunami GPX-R V2. Most likely, the PS Audio power supply was sensitive to this enhancement. We likened the effect of getting more depth to a higher f-stop in photography. The last cable we put to the test was the 2.5 meter version of the Tunami II SP-Y V2 loudspeaker cable. As expected, the wire was 102 SCC in the Nigo geometry. Also as expected, it had at least 3 layers of applied shielding. The outer sheath was the now familiar slightly rough Polyurethane sheath whose whiteness proved quite prone to smudges. Take care when laying out this cable on a not squeaky-clean floor! Under that white jacket sit a copper foil, a layer of carbon PE and a microwave-absorbing polyolefine polymer. Each of the two 102 SCC wires has a jacket of polyolefine. A third wire, now OFC, is used as drain connected to the copper foil shield. The loudspeaker cables are terminated with SPSL spades that are built up from a silver base plated with platinum. Just like with the Focus 1 XLR plugs, the SPSL spades are furnished with red or blue ‘jewels’. Before the white Nigo cable splits into two separate wires, Oyaide fit a metal collar/splitter as a finishing touch.


We deployed the Tunami II SP-Y V2 in our analog system where the cable served up signal to the white Sounddeco Alpha F3 which also matched on colour. After ample burn-in, the sound—tube sound from the Audio Note Meishu, Trafomatic Kaivalya or PTP Audio Blok20—was denser than the Nanotec SP#79 MK4 on duty before. The sound had more impact on the gut and was not only acting upon the ears. Not that there was suddenly more bass or boom but an enhanced form of overall physical involvement which was really pleasurable. Let us start our conclusion with stating that getting a box of cables is fun and not something with a dark undertone like Forrest Gump’s "life was like a box of chocolates. You never knew what you were gonna get." Part of the fun was that all cables came from Oyaide's mid-price range except for the M1E/F1 terminated power cord which nearly hits the €1’000 threshold. This combined with the wide range of cables all built with the same conductor and only differing in assembly due to specific applications makes it eminently doable to configure a full Tunami loom for many music lovers not on an unlimited budget. The benefits of a single supplier, single design philosophy hence consistent material/mechanical tuning really pays off. Then add Oyaide’s attention to detail and this package completes very nicely indeed!
Condition of component received: Excellent.
Reusability of packing: Simple outer box, extra scratch protection where needed but nothing fancy or silly expensive.
