The Headroom Max was Headroom's cost-no-object flagship amp before cost became an object for their company. This amp has two TRS jacks that can be used simultaneously and an Alps RK50 pot. This retailed for $3500 and has been untouched in the rack since purchased. Will ship in original Headroom boxes.
From their manual:
"HeadRoom’s ﬂagship Max ampliﬁ er is nothing short of an allout assault on the world of headphone audio ampliﬁ cation. The Max amp is the gleaming culmination of HeadRoom’s 13-year
quest to create the ﬁnest headphone amp available anywhere.
We employ a painstaking high-quality build design that utilizes
only the ﬁnest audiophile-grade components regardless of cost
concerns to produce an intensely liquid, transparent and accurate sound rich in exquisite musical detail and jaw-dropping dynamics. The sense of space around the notes and the hidden
nuances of the performance become vivid, expressive entities
with the Max ampliﬁer. The Max provides the ultimately reﬁned
route to the pure audio resolution that we feel exists only on
reference headphones. Let the Max become your personal route
to transcendent sonic bliss and get it perfectly right between
