KATLAS Integrated Amplifier

The Katlas is a 145watt per channel integrated amp that shares it's sonic signature with the GDC. With the extra wattage and power supply storage capacity, the Katlas has a more authoratative bottom end while retaining the overall balanced presentation of the music. Its quick and transparent quality lets you hear through the performance and the venue acoustic*. The Katlas strikes that perfect balance between delicacy and authority that will make you simply want to spend more time listening to music.

*New term invented by Gilbert. In his own words venue acoustic is, "you can hear the acoustic of the concert hall or recording studio where they record the moooosic. Venue Acoutic is actually a chink ga lish. When I type it, my mind had the venue and the acoutics in mind so there is the birth of a new term." So there you go. Happy Birthday Venue Acoustic. :)
