Wyred4Sound STI v2 Series Integrated Amplifier
Available in 2 power configurations, our STI-500 v2 and STI-1000 v2 integrated amps are consistently lauded by critics as one of the best integrated amps on the market. The STI v2 series features a reference quality analog pre-amp and two mono amps built into one chassis, creating exceptional performance in a convenient form factor. The new STI v2 models feature all-new ICE modules for this series, borrowed from our very successful and award-winning ST mkII series. Also featured for the v2 series is a new chassis color: a very sleek antracite gray, as well as traditional black.
Because the unit is efficient and consumes very little power at idle, the STI is a truly green product that conserves all its energy for your music. On the outside, the STI’s Vacuum Fluorescent Display and optical rotary encoder not only look great, they ensure years of trouble-free listening.
Kimber Wire/WBT binding post upgrade:
Under the Select Options dropdown, you can choose to upgrade the internal wiring and binding posts of your STI! 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 STI.
