Subsequent upgrades, improvements and tweaks
added the '+'. By now many companies would have renamed their models but Adam stuck to his established nomenclature and customers probably got used to it. Visually the PC-2 EVO+ is a typical hifi component of 440x115x400mm WxHxD weighing 15.6kg. Its maximum output power and current delivery are 3'680W and 16A respectively. Peak overcurrent protection is 20'000A. A black or silver brushed aircraft-grade aluminium fascia affixes with four hex screws in each corner. A rather large plexi window with logo, model name and one white LED between sits at the centre (one may order an LED of a different colour). Higher-tier GigaWatt models sport voltage displays but not here. Six Schuko sockets grouped in three categories occupy the rear. From left to right, these pairs are meant to work with digital, analog low-draw and analog high-draw components respectively. There's also a nameplate with serial number, wall voltage, input socket type, power consumption (9W) and DC Blocker option plus 'Engineered & Handcrafted in Poland'. A red LED confirms proper power polarity and an IEC power inlet with mains switch completes the list.


The sides and top cover are U-shaped sheet metal finished in matte black and decorated with a deeply engraved good-looking logo on top. The underbelly sports four aluminium footers with rubber ends. These feet are big, heavy and of yeoman quality plus there's a €660 proprietary roller-ball isolation option. A €300 upgrade worth taking a closer look at is the DC Blocker. DC on the alternating AC sinewave creates asymmetries which tend to impact transformers, causing them to hum. To conclude the external inspection, the GigaWatt PC-2 EVO+ looks utilitarian yet finely put together. Stripped of visual flamboyance, it seems modest and minimalist. It's once we pay attention to the inside that things really escalate. I was told that each component in any GigaWatt product is produced for them exclusively. Their early days of relying on off-the-shelf parts are long behind them. Today they identify the best specialty suppliers, then cherry-pick and customize the best parts. To meet the demands of his well-developed sales network, Adam's financial commitments are big. When he orders, he orders a lot. That creates more supplier willingness to accommodate customizations.



With this background and high QC, everything about my loaner fit perfectly and screamed quality even though the product itself is cosmetically simple. The fantastic innards showed not a drop of stray solder and instead, large traces, clamps and bolts which were exceptionally orderly. The core circuit is based on multi-stage parallel filtration across seven main blocks. Phase control, surge suppression, DC blocking, compensation battery charging and entry-level filtration are all found in the starter module under the biggest hood next to the IEC socket. Then the current passes through highly conductive and massive C11000 cathode-copper rails to a double buffer loaded with high-quality compensation batteries designed by GigaWatt. The goal here is to increase current efficiency for non-linear loads like power amplifiers and decrease any power differences between the filter's input and outputs. Past this stage and prior to the outputs again via massive copper rails sit three separate sections powered in parallel. Each one is a bit different to work with different loads yet all sport RLC blocks with GigaWatt's proprietary filtering and decoupling capacitors topped with iron-powder core filters.


Adam shared that the only company able to deliver suppression capacitors to his specs—Miflex—ended up being just an hour's drive from GigaWatt's HQ. When asked about differences between the PC-2 EVO+ and my old PF-2, he explained that among many other things, the latter shared its distribution branch with all connected devices and lacked any buffering circuitry. The most important difference of course was his latest concept of lossless power delivery. The PC-2 EVO+ can be bought with any GigaWatt cable but the LC-3 Mk3+ is suggested and that's what I received. If purchased separately, it goes for €990. Like all GigaWatt cords, it is quite stiff. Inside are eight 1.5mm2 solid-core OFHC C10100 copper strands isolated with elastic polyethylene with lowered dielectric constant, then wrapped in an aluminium shielding foil and finally sleeved in soft PVC topped with an anti-static mesh. The power plugs are GigaWatt's own with gold-plated brass contacts and all connections are bolted, not soldered.
