TUNERSYS 120W Audiophile Linear Power Supply for WS161 | Official Store

I used to think all power supplies were the same. Then I plugged this into my WS161. The difference was audible within seconds – a cleaner, more three-dimensional presentation. The background noise floor dropped to inaudible levels. The sealed toroidal transformer and passive cooling design mean no fan noise, no transformer buzz – just dead silence. The aviation-grade connectors inspire confidence. The 3kg weight is substantial but reasonable. Factory direct pricing makes this an easy upgrade decision. Highly recommended for anyone serious about their WS161 setup.

The WS161 deserves a power supply that matches its performance. This 120W linear PSU is exactly that. The DC 18V output is stable under load, and the 6.5A current capacity means the amplifier never starves for power. The difference in dynamic range is immediately apparent. The aviation connectors are a nice touch – they lock securely and feel industrial-grade. At approximately 3kg, it's heavy enough to stay put. The aluminum chassis is well-finished and dissipates heat effectively. If you own a WS161, do yourself a favor and add this.

My WS161 system was already sounding great, but I felt something was holding it back. This 120W linear power supply was the missing link. The upgraded Nippon Chemi-Con capacitors and sealed A-grade toroidal transformer deliver incredibly clean power. The result? A darker background, more precise imaging, and better transient response. The aviation connectors are over-engineered in the best way. The aluminum chassis looks right at home next to my WS161. For anyone chasing maximum performance from their TUNERSYS setup, this is non-negotiable.

I've been using the WS161 for months and loved it, but the stock switching adapter always left a slight high-frequency noise floor. Upgrading to this 120W linear power supply was a revelation. The background became completely black – silence between tracks is now absolute. Dynamics tightened up noticeably. The 3kg weight tells you this is serious gear. The sealed toroidal transformer and Nippon Chemi-Con capacitors are no joke. If you own a WS161, this is a mandatory upgrade. Factory direct pricing makes it a no-brainer.

I'm an electrical engineer, so I appreciate good power supply design. This unit ticks all the boxes. The sealed A-grade toroidal transformer minimizes stray magnetic fields. The CLC filter with high-quality Nippon Chemi-Con capacitors keeps ripple to an absolute minimum. The 18V / 6.5A output provides clean, stable power even under heavy load. The military-grade aviation connectors ensure a reliable connection. The aluminum chassis acts as an effective heatsink for passive cooling. At approximately 3kg, the weight reflects the quality inside. A well-engineered product at a fair factory-direct price.

I've tried various aftermarket power supplies, but nothing compares to this custom-engineered unit. The DC 18V / 6.5A output is exactly what the WS161 needs to perform at its peak. The aviation-grade connectors are a nice touch – solid locking mechanism, no wobble. The aluminum chassis runs cool even after hours of listening. The difference in soundstage width and instrument separation was immediate. My only regret is not buying this sooner. Worth every penny.

I live in an apartment with dirty power. The WS161 always had a faint background hiss through my high-sensitivity speakers. This linear PSU completely eliminated it. The CLC filtering with high-end caps works. The sealed toroidal transformer also means zero mechanical hum – the unit is completely silent. At 3kg, it's substantial but sits nicely next to my WS161. If you're chasing that last 5-10% of performance, this is where you get it. Highly recommended.

I've been an audiophile for 20 years and know that linear power supplies make a difference. The stock switching adapter was the weak link in my WS161-based system. This upgrade delivers on every promise – darker background, reduced noise floor, better dynamics, and tighter bass. The 18V / 6.5A spec provides plenty of headroom even at high volumes. The build quality is excellent – military-grade aviation plugs, solid aluminum chassis, passive cooling. A genuine high-end component. Factory direct pricing is very fair for what you get.

I was skeptical that a power supply could make an audible difference. I was wrong. After swapping the stock adapter for this linear PSU, the WS161's presentation became more relaxed and natural. High frequencies lost their slight edge. Bass became more articulate. The improvement is subtle but meaningful – it's the difference between good and great. The sealed toroidal transformer eliminates any chance of mechanical noise. The 3kg weight gives confidence in the build quality. Expensive? Yes. Worth it? Absolutely for those who care about sound quality.

I've tried generic linear power supplies with my WS161, but none had the correct voltage and current combination or the right connectors. This unit is purpose-built. The 18V / 6.5A spec is exactly what the WS161 needs for optimal performance. The CLC filtering with premium capacitors ensures ultra-low ripple. The sealed toroidal transformer means no mechanical hum – something that plagued my previous linear PSUs. The aviation-grade DC plug provides a rock-solid connection. This is how the WS161 should have been delivered from day one. An essential upgrade for discerning listeners.

I've owned my WS161 for two years and always enjoyed it. But after adding this linear power supply, I realized what I was missing. The stock switching adapter introduces subtle noise that you don't notice until it's gone. This unit delivers dead-silent background, improved dynamics, and a more natural tonal balance. The DC 18V / 6.5A output provides ample headroom for the built-in 50W amplifier. The aviation connectors feel premium. The 3kg weight inspires confidence. If you're on the fence, just buy it. You won't regret it.
