The Apex Pinnacle
The Apex Pinnacle is a highly evolved vacuum tube preamplifier and headphone amp.
For the highest quality tube sound without harshness or distortion, it employs two single-ended tube stages. The input stage uses the venerable 6SN7 tube, often regarded as the best tube ever made for audio voltage amplification. The power stage uses triode-connected 307A directly-heated pentodes, or optionally Sophia Electric PX4 triodes. This carefully matched arrangement cancels some of the softness - actually, second-order harmonic distortion - that is often associated with single-ended tube amplifiers. The result is pure, clean, musical sound.
Both the input and output signals are coupled through very high quality audio transformers, providing truly balanced inputs and outputs. Three inputs are accommodated, from either balanced or unbalanced RCA or XLR connections. The versatile output circuitry allows the connection of high or low impedance headphones, as well as a power amplifier. 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.
Components are carefully selected from throughout the world, from hand-machined Japanese Teflon tube sockets and aluminum knobs to transformers custom-made in Europe. Unlike many so-called "high-end" audio components, the Pinnacle is not just a prettied-up marginal design implemented with poor-quality parts from third-world nations. It is truly a high-end component from design through assembly, hand-built in the USA.
To keep the noise level as low as possible, the Pinnacle places the power supply circuitry in a separate enclosure, which may be located up to five feet from the amplifier. Special transformers, Silicon Carbide rectifiers, and a sophisticated filament supply help ensure the Pinnacle is as quiet as it can be.

HI All,
We have 2 new products to announce and we are now taking pre orders for them!!!
The Peak is a new hybrid headphone amp/preamp and the Volcano a high end power supply upgrade that currently works with the Peak and TTVJ FET-A. Both are designed by Pete Millett and sold exclusively through TTVj.
The Peak comes supplied with a 120/240v external power supply for $1400 or with the Volcano for $2000. The Volcano as a separate purchase is $650 so you can save $50 by purchasing them together.
Here are the details...
The Apex Peak represents a fresh approach to a mid-priced headphone amplifier and preamp.
The Peak is a hybrid amplifier, pairing a 6SN7 vacuum tube voltage amplifier stage with a class-A single-ended MOSFET output stage. Unlike some hybrid amplifiers on the market, the Peak generates a true high voltage B+ supply to operate the tube where it belongs – at a very linear operating point. The single-ended MOSFET output stage is DC-coupled to the outputs to provide excellent drive capability and deep bass response.
Three inputs, selected by a front panel switch, and a line output (which is automatically muted when you plug in your headphones) are provided, so you can use the Peak both as a headphone amplifier and a pre-amp for a loudspeaker system. Relays are used to keep the signal path short and direct.
The standard Peak is powered by an external switching power supply. For ultimate fidelity, an optional linear power supply is available that matches the amplifier in appearance and performance.
Unique design and quality parts combine to give the Peak optimum sound at an affordable price. Unlike many so-called "high-end" audio components, the Peak is not just a prettied-up marginal design implemented with poor-quality parts from third-world nations. It is proudly hand-built in the USA.
