CanJam 2012 has brought about another award/acclaim for the Pinnacle. The Audio Beat named it best of show!

The Pinnacle wins an award! The Absolute Sound Has given the Pinnacle the prestigious Editors Choice Award for 2012! Look for it in the March issue!

From the July/August issue of The Absolute Sound with a review from Dick Olsher of our Apex Pinnacle! Here are some quotes... and the whole review here...:

“It was evident in just a quick minute that the Pinnacle was an extraordinary preamp. Its level of clarity and soundstage transparency place it firmly in the top echelon of line preamps”

Dick Olsher, The Absolute Sound, July/August 2011


“Its overall soundstage presentation exhibited considerable grandeur: a wide and deep 3-D perspective with rock stable image outlines.”

Dick Olsher, The Absolute Sound, July/August 2011


A new review from John Crossett at The Audio Beat!

"The sound: remarkably pure and accurate, effortlessly revealing, and subtle as could be."

Chris Martens  Playback  speaking of the Pinnacle!

And this just in from a Pinnacle owner!


As you said, the amp is basically transparent to the 6SN7 quality, and I've tried some great ones before settling on the Marconi Osram B65 variant, and I'm getting the best sound I have ever heard.  On a scale of one to ten, this thing is about 23.  Quite amazing.  (I'm using the

Also, I really appreciate the level of basic technical expertise.  I live in a very, very hostile RFI environment - 11 blocks from the Empire State Building, which has 244 transmitters on it, on a direct line of sight through my window, and background noise is totally non- existent.

I'm a very happy customer.  Expensive, but you get what you pay for.

Best always, Jim

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 the 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.
