Our ultra-high end ST-500 mkII and ST-1000 mkII amplifiers deliver all the refinements of our award-winning mAMP monoblocks with the convenience of one component. As with the mAMP, both the ST-500 mkII and ST-1000 mkII are built on the latest generation of ICEpower® technology and boast a 3rd generation input stage that produces smooth upper-mids and low and tight bass. With 14AWG OFC wiring direct soldered to gold plated 5-way binding posts, optimum power delivery and reference audio quality is guaranteed.
Whether using balanced or unbalanced inputs, the dual differential common mode converter ensures a perfectly balanced signal is fed to the power amp, while the quad FET buffer optimizes synergy between components. Ruggedly built yet exhibiting a smoothly toned industrial design, our STmkII series showcases unmatched value and performance.
Kimber Wire/WBT binding post upgrade:
Under the Select Options dropdown, you can choose to upgrade the internal wiring and binding posts of your ST mkII! We replace our usual OFC internal wiring with premium Kimber TCX wire, a 14 ga. multi-gauge/multi-strand OFC wire for improved transparency and sound. We also replace our normal binding posts with high-end, German-made WBT nextgen® binding posts for a better fit and connection. Consider this upgrade to maximize the performance of your ST mkII.
