The Apex Pinnacle 2 and Pinnacle 2 Ultra

The Apex Pinnacle 2 and Pinnacle 2 Ultra are an evolution of the Apex Pinnacle headphone amp and preamp.

Like its predecessor, the Pinnacle 2 uses a single-ended two-stage amplifier circuit using a 6SN7 and two PX4 directly-heated triodes. The Pinnacle 2 Ultra uses the exquisite Emission Labs PX4 tubes.

Both the input and output signals are coupled through very high quality audio transformers, providing truly balanced inputs and outputs. New C-core output transformers are employed in the Pinnacle 2, with an amorphous core in the Ultra version. Three inputs are accommodated, from either balanced or unbalanced RCA or XLR connections. Three output impedance selections are available for both balanced and unbalanced headphones, and a preamp out mode drives both balanced and unbalanced outputs. The input and output selections are made via a front panel switches, which activate relays that are strategically located to keep the signal path direct and pure.

Although it uses the same basic circuit as the original Pinnacle, the Pinnacle 2 received many component upgrades, like a new medical-grade power transformer, as well as a number of aesthetic enhancements. The Pinnacle 2 Ultra includes several key upgrades from the Pinnacle 2, including silver foil paper-in-oil coupling capacitors and Spiral Groove Strange Attractor feet.

New Silver (P2) and Wine (P2 Ultra) finish knobs and transformer covers are cosmetic upgrades over the previous model.

Also added is a gain switch on the rear panel for ease in changing the gain of the Pinnacle!
