The CS2  Integrated Amplifier

Taking the term upgradeable to a new level.

The CS2, our new entry level integrated amp is available in two versions.  A 50 watt per channel version and a 120 watt per channel version.  The input stage is based on the NSL and the other stage is similar to the BC1022 (80 watt version).  The amplifier is designed on a semi modular level.  The user can purchase the base model and later upgrade with various options.

In order to make the amplifier accessible to as wide an audience as possible we have decided to make the faceplate an optional accessory. Not to worry, the CS2 chassis has a sub plate which will keep dust , fingers and cats away from the internal circuitry.  The faceplate is only a cosmetic item.

The CS2 has a speaker terminal switch which turns the speakers off when using headphones
