Audio Laberty MC & MM Phono Stage Preamplifier For Moving Magnet and Moving Coil Cartridges, created by a retired engineer,Sam Ngai

Audio Laberty LP-121phono stage uses twoindependent power supplies to minimize crosstalk and noise, and maximize signalintegrity. The single-endedclass-A circuitry uses no negative-response. RC attenuation is used for theRIAA network. The LP-121 has two sets of RCA inputs, and can easily meet the requirementof systems with two turntables, or two arms on one table. The inclusion ofvariable loading and capacitance makes it a good match for many differentcartridges. Several layers of shielding are used to isolate the circuit fromEMI/RFI.

It was designed to be a MovingCoil & Moving Magnetselectable, the switched is mounted on the backof chassis, making it compatible with virtually every MC/MM cartridges in the market. The power supplytransformer will be made to order based on customer prefer AC voltage. It alsohas a detachable cord socket;chassis mount jacks and exceptional build quality.

There is nothing as affordable and versatile in a phono stagethat comes close to the listening pleasure you will receive from this world-classdesign. If you treasure analog with incredibleextension at both frequency extremes, taut powerful bass, and extended airy highs as I do, particularly if you\'re a fan ofwell-recorded classical works, it should be on every audiophile\'sshort list of high-performance phono stages.

The selection of components are critical to thesound reproduction, I used good quality capacitors and resistors and solder onboard by hand.

Pls note that this is a custom made toorder and it will take me about 7 days to complete production upon receipt ofpayment. So you will expect shipment for less than 8 days. The attached photos showno silk screen logo on however I will add my logo “Audio Laberty” and silkscreen wording on the front and back side of chassis for any of orders.
