Pass Labs New Headphone Amp $3,500 Review

“The foundation of the HPA-1’s engineering is a custom, low-noise shielded toroidal power transformer feeding a discreet low noise regulated power supply for the audio circuits. The importance of the power supply is often overlooked and plays a large part in overall performance of the amplifier. The HPA-1’s amplifier circuits are low-feedback, wide-bandwidth discreet designs employing J-Fet input stages and Class A-biased direct-coupled MOSFET output stages. The HPA-1 easily drives headphones presenting loads from 15 to 600 Ohms, particularly excelling on planar headphone designs. The sound is rich and detailed.”

“It’s hard to find flaw for the money. No, the system doesn’t have the home-shuddering dynamics, the extraordinary detail and transparency, the volume headroom, the bass extensions, or the seamless coherence of a system costing at least as much as an S-Class Mercedes. And the headphone amp, though good, is no match for the anointed standalone ones. But the thing is the Lindemann/ProAc combo gets close enough. Some think there is no such thing as a law of diminishing returns in audio, but you could be mistaken for concluding that line in the sand is drawn here.”


Trafomatic Audio Head 2 $1700 Review

” The Head 2 uses ECC88 input tubes and 6N30P output tubes, one in each channel for a total of 4 tubes. The tubes are in a Class-A push-pull configuration with output transformers. The amplification is 100% tube based and can deliver up to 2W of power into 50 ohms or 26dB of gain if using the Line Out. I am a huge fan of the ECC88 tube family as most of them have low noise and a clean linear tube sound. The Head 2 comes stock with Electro-Harmonix 6922 and Sovtek 6N30P tubes which worked well and provided fantastic sound right out of the box.”

” The Curve is built out of plastic. One side is gray plastic, the other is transparent. It looks plastic, and it feels plastic. The look certainly doesn’t scream high end, but then neither does the price ($250), so no problem there. More important is that, even though it does look and feel like plastic, it looks and feels like solid plastic. It may not be a modern art masterpiece, but it is functional”

Reference 3A Nefes Loudspeakers $9990 Review

” It seemed to me that the Nefes had been designed by people whose most important consideration is quality of sound. In discussing the speaker with Tash Goka, I was struck by the care and thought that had evidently gone into every facet of the speaker’s design and construction, right down to the phase plug at the center of each midrange-woofer, which Reference 3A calls its Surreal Acoustic Lens, said to prevent the formation of air vortices and turbulence at the deep center of the cone.”
