ZOTL40 Reference+ Upgrade Program

Two years after releasing the award-winning ZOTL40 Reference power amp, LTA is proud to announce the next generation of our flagship amp, the ZOTL40 Reference+.

After trying over two dozen component combinations, and countless hours of listening tests and comparisons, the new ZOTL40 Reference+ upgrade improves the tone and texture across all frequencies, and there is more detail and clarity around the performers.

These sonic upgrades are achieved through adding a massive 100,000µF of additional capacitor storage and changing resistors at key points in the audio path to non-magnetic Audio Note Tantalums, each value specifically chosen for their location.

Free shipping is included in all Reference+ upgrades for US customers.
