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.
