Niangua 5 Foot, 9 Gauge Power Cord With 20 Amp IEC

This is a pre-production Niangua power cord that has been connected to a RGPC power conditioner in one of our demo systems here for the past several years.  It is five feet long and features a Watt Gate 330i plug and 350i HC 20 amp IEC plug. 

This is the same 9 gauge wire, build specifications, and connectors that are used in our premium series power cords.  This pre-production model has all black Techflex and shrink tube.

Niangua power cords are built in the USA using the finest materials and most intelligent and effective design techniques to offer a product that is unparalleled in performance at its asking price. 

This power cord is sold as is in excellent working and cosmetic condition.  The gold plating on the 330i plug is a little weak.

Lieder Cables Maxx Generation 2 RCA Interconnects

Production has ended on the Lieder silver interconnects and loudspeaker cables.  We expect a new series of models to appear sometime in the future, but for now we have seven pairs of Maxx Generation 2 interconnects in the one meter length with RCA terminations for sale. 

Lieder cables are designed and built in the Netherlands.  Their design philosophy can be traced back to the early days of Prima Luna and Siltech.

These interconnects have been used for demonstration purposes and all seven pairs are in excellent condition.

These have the milled locking RCA connectors as are shown in the photo, and have the gray sheath.  These are the best silver cables that we have ever used here, and we hate to see them go.  These interconnects come with our 30 day store warranty, and will likely be the last interconnect cables you ever buy.

In the one meter length, these sold new for $1600.00 per pair.  The price of silver has gone up considerably since these were introduced.  The price would be much higher today if they were still being manufactured.  Prices are below.

Retail Price:  $1600.00

Regular Price:  $800.00

Cash Price:  $750.00

Regular Price – All Seven Pairs:  $4200.00

Cash Price – All Seven Pairs:  $4000.00


Final Clearance On Black Bristle Listener Select Record Cleaning Brushes
