CH Precision L1 - Dual Monaural Line-stage, Factory certified w/2-year warrantee

Just returned from the Swiss factory, a pair of CH Precision L1 Stereo line stages. They have been thoroughly inspected and tested along side new production LI's. New displays and this one has a brand new chassis so it is essentially new at a fraction of the original price. CH Precision dealers are not allowed to advertise current units at discounted prices so you will need to contact me for prices. I'd rather talk to the buyer anyway:)

The customer that traded these units in had the four box dual monaural L1 set-up. So a separate L1 pre and X1 power supply for each channel. While at the factory, each L1 was fitted with a second input board so these are now stereo units. They can be converted back to monaural units at any time with no cost penalty. In other words, any CH Precision product can have the optional features added at any time for the same price as if you had ordered the options up front. A very customer friendly company!

Some factory marketing speak...

Product Description

Any great line-stage must possess transparency, ultra-low noise performance and absolute stability. It must anchor the incoming signals and deliver them onwards, propelled from a firm footing that ensures dynamic and musical authority. It must pass the source signals in your system, without limitation or disturbance, leaving no trace of itself on their passage. Any great line-stage needs to be the next best thing to sonically and musically invisible, the hi-fi equivalent of effortlessly enacting its own audio super power. Input voltage is switchable between 115v or 220v

Like all CH Precision products, the L1 uses fully discrete, balanced and complementary design, ultra-short signal paths and exactingly selected components. It is fed from heavily regulated and filtered power supplies, is wide-bandwidth, high slew-rate and DC coupled. But in this critical application, that’s not enough. It’s one thing to eliminate unnecessary components from the signal path and eliminate DC offset at the inputs, but the L1 takes things much, much further than that. Completely separate left and right channel circuit boards prevent crosstalk, while a super sophisticated, software driven R-2R network for each channel employs precision metal-film resistors and allows precise level control in 0.5dB steps with the minimum possible number of components. DC offset is monitored and eliminating not just at the inputs but throughout the volume control ladder and at multiple points throughout the entire circuit. That makes the L1 not just one of the quietest line-stages ever built, it makes it one of the quietest in operation too.

Another hallmark of CH Precision is the user adjustability of their electronics. And the L1 is no exception. It also allows the user to name the inputs to reflect what source is being used. Display can be changed to any custom color. Can be dimmed or brightened to taste or it can be arranged to just turn off after a short time.
