OPPO HA-1 Headphone Amplifier Review

HA-1

Since headphones have become so popular, it seems only natural that dedicated headphone amplifiers would follow. Many have come to market, and the OPPO HA-1 headphone amplifier has just been introduced. It has numerous digital and analog inputs, and the output stage operates in Pure Class A. It also can handle digital audio in the new ultra-high resolution formats, e.g., 24/352.8 PCM and DSD128. A dynamite product from a dynamite company, the HA-1 is a champion in the ring!

OmniMount PJT40 Projector Mount

OmniMount PJT40 Projector MountCompared to mounting a flat panel TV, installing a projector is a pain. You need to get the screen perfectly level and flush with the wall. Then you have to mount the projector to precisely line up with the screen. It has to be perfectly parallel to the screen or you'll see distortion. Getting the projector perfectly level usually means lifting it up to make small adjustments to the feet, placing the projector down, and checking again. Since I review multiple projectors every year, I do this dance too many. By the time I get a projector perfect it's almost time to box it up and send it back to the company. The PJT40 projector mount from OmniMount is designed to make this easier than before and so I decided to install one in my home theater to find out.

OPPO PM-1 Planar Magnetic Over-the-Ear Headphones Review

OPPO PM-1OPPO, known for their very high quality universal players, including the latest OPPO BDP 105 Blu-ray player, has now ventured into another arena: headphones. Their first model, just released, is the OPPO PM-1, which is an over-the-ear design, using planar magnetic drivers. At a time when everyone seems to be offering headphones and/or earbuds as part of their product portfolio, only a handful really stand out as top notch performers. The PM-1 is destined to join that group. NOTE: INFO ON THE NEW OPPO PM-2 HEADPHONES IS POSTED AT THE END OF THIS REVIEW - APRIL 29, 2014.

ADE-24.1 Analog Digital Enhancer

ADEThe ADE-24.1 Analog Digital Enhancer is an accessory that has been around for a long time. It works at low voltage (e.g., RCA analog output from CD player, iPod, etc.) and manipulates the harmonics. I got one of these units at the California Audio Show and the demonstration definitely indicated that it could improve sound (make it sound more appealing, and widen the sound stage), so I decided to bench test it to see what it does.

NAD HP20 In-Ear Headphones (Earbuds)

NAD HP20 In-EarphonesThe HP20 is a welcome addition to the in-ear (earbud) headphone family from none other than NAD. These little guys pack a lot of punch into a small package and at $169 they cost almost half as much as the $299 NAD HP50 headphones. Like the HP50, the HP20 also takes advantage of the years of research spent at the acoustic labs of Canada's National Research Council. This research is what Paul Barton utilized to create RoomFeel, the concept of making a headphone sound more like listening to a pair of speakers in a room.

NAD HP50 Viso Over-the-Ear Headphones

NAD HP50 Viso Over-ear Headphones

The NAD HP50 is the latest headphone design from Paul Barton, founder of PSB, a sister company of NAD, and features a new trademarked concept called RoomFeel. RoomFeel attempts to recreate the sound of listening to high-end speakers in a room. Most listening rooms add a low frequency bump to the sound that is often not taken into account when designing headphones. A room gain compensation transfer function was developed to add a +3 dB per octave boost from 200Hz down to 50Hz in order to replicate the fuller, warmer sound of a room. Clearly a lot of time and engineering has gone into the development of these headphones, the only question is, did it pay off? Yes it most certainly did.

Emotiva Stealth DAC

Emotiva Stealth DACListening to my records one night, I received an email from Susan Johnson asking if I would be willing to review the Emotiva Stealth DC-1. Would I ever! Last year I tried the Emotiva USP-1 preamp and UPA-200 amp in my system and I have been very happy with the combination. Needless to say I was very curious to see and hear this reference piece from Emotiva.
