The 5 series
Designed and handbuilt in Boulder, Colorado—the 5 series has withstood the test of time as ultra-reliable, reference quality gear that has been heralded by reviewers worldwide for its superior musicality. Adhering to our philosophy of upgrading rather than obsolesence, each of the 5 series products receives perodic upgrades reflecting significant technical improvements we have discovered through our continued reasearch and developement. Every product in the 5 series is designed for a life time of musical enjoyment.

“…the AX-5 is not only, overall, the finest-sounding amp I’ve ever heard, it ranks as one of the finest components I’ve heard of any type.”
