CH Precision A1 stereo amplifier
If you are reading this ad, you are likely aware that CH Precision makes some of the finest sounding amplifiers in the entire world. The A1 is the predecessor to the A1.5 which is CH Precision's entry level amplifier. The A1.5 retails for $39,995.00. This amplifier when new retailed for $37,475. Price just reduced by $1500!
This particular A1 is being sold on consignment - its owner upgraded to an M1.1. This is the way to get into a CH Precision amplifier without spending new BMW money for an amp.
If you are new to CH Precision amplification, these amps have some features which make them very unique in the industry such as adjustable global feedback, adjustable display settings to show power, status or display off, adjustable gain settings to work with a variety of preampfification products, etc. Liquid HiFi is happy to install or help you maximize the sonics of your new CH Precision product.
If you currently own an A1, we DO have a second A1 which could be sold as an A1 mono upgrade - inquire with us for details.
