The manufacture of the PS1000 housing is a complicated and proprietary process that results in a sonic signature and voicing that is the Grado hallmark. An important step in this process is the metal housing being stressed and then cured resulting in a unique aesthetic finish. As with all Grado products the most important aspect is the sound. If you are interested in owning the finest headphone Grado has ever produced then the PS1000 is the choice that will satisfy the most critical music lovers.

PS1000 REVIEW

Review

Grado is one of America's oldest hi-fi companies. In the 1950s it manufactured phono cartridges, turntables, and speakers. While Grado still makes a full line of highly regarded cartridges (budget-priced all the way up to high-end models), it's perhaps better known today for its headphones, which spring from the professional line it began manufacturing in the 1980s. The company now offers a complete line of headphones ranging from the $49 iGrado to the $1,695 flagship we're reviewing here, the Professional Series 1000 (PS1000). It still has the retro/industrial styling Grado's famous for, but we think it's the best-looking and best-sounding headphone we've tested from the company. That also makes it one of the best pair of headphones we've ever heard.

Design and features

All of Grado's high-end headphones ($495 and above) have featured either wood or machined metal earcups, but the PS1000s use a combination wood-metal earcup. The headphones' drivers are bonded, without any metal fasteners, to a mahogany mounting piece that is in turn bonded to a solid, round metal earcup. The wood-metal design approach is unusual, but it seems to produce a more natural sound than previous Grado headphones. The PS1000s' earcups certainly feel remarkably solid and inert, desirable qualities for speaker cabinets and apparently for headphones.

The PS1000s' drivers don't look much different than the ones we've seen on other high-end Grados, but Grado claims they are unique to the PS1000s. They're open-back headphones, so you can easily hear external sound around you. (Since the PS1000s are intended for home use, we don't consider that to be an issue.)

The leather-covered headband is a nice finishing touch for the design. And while this is a rather heavy headphone, it didn't feel heavy on our ears. Ear cushions are large bowl-shaped black foam units, which are user replaceable. The overall result is that the PS1000s are the most comfortable Grado headphone we've ever tested.

The 5-foot, eight-conductor cable is a little thicker and more flexible than what we've seen from Grado before. It's Y-shaped (with cords going to each ear), and terminated with a gold-plated, 6.3-millimeter phono plug. The PS1000s also come with a 15-foot extension cable and a 6.3-millimeter to 3.5-millimeter (minijack) cable adapter. The adapter is a bit bulky but works well enough; we used it when we listened to the PS1000s with our iPod.

Performance

Before we get into the PS1000s', sound we'd like to point out that Grado headphones, from the affordable SR80i up through the line, share a "house" sound. Grados sound like Grados: they are all exciting, extremely dynamic performers, and while the PS1000s share those qualities, they're more refined, sweeter, and with a more sophisticated design.

Since the PS1000s are made in Brooklyn, we decided to start our listening sessions with a Brooklyn band, Oakley Hall. The group's "I'll Follow You" CD sounded great, with the sort of full-bodied dynamic swing you rarely hear from contemporary rock CDs. Patrick Sullivan and Rachel Cox's twin lead vocals were natural and clear.

Review

Grado RS-1i headphones ($695) have been our reference for years, so we know their sound well. Switching back and forth between RS-1i and PS1000, the difference can be summed up with one word: scale. The RS-1i is still great, but it's more closed-in, more "inside the head" sounding. Stereo imaging is much wider over the PS1000, but it's also more spacious. The RS-1i is dimensionally flatter, and then there's the bass. Yes, with the PS1000 there's more of it, but the quality, depth, and palpable bass texture come through like never before. Listening to any decent-sounding acoustic jazz CD, we were much more aware of the bass player's contributions.

The treble is likewise better resolved and clear. Cymbals sizzle more and they have greater presence through the PS1000s. But rather than try to describe different frequency ranges, it's the entirety of the sound that's a huge advance over what we've heard before from Grado.

DVDs and Blu-rays sounded pretty terrific over the PS1000s. Listening over our Onkyo TX-SR805 receiver, the circle of drums scene from the "House of Flying Daggers" DVD had tremendous impact and the sound of each drum thwack was clearly defined. It was undoubtedly better than Sennheiser's flagship HD 800 headphones in that regard. To hear this level of detail over speakers you'd need to spend at least five times the cost of the PS1000s.

For CDs and SACDs we switched over to our Woo Audio WA6 Special Edition headphone amplifier. A great-sounding SACD like "Symphonic Dances" with Keith Lockhart conducting the Utah Symphony Orchestra put the PS1000s' strengths in perspective. Notably, it was the scale of the sound, the orchestra was huge, and during the music's quieter interludes we could hear the sound filling the Abravanel Hall in Salt Lake City. The strings were the perfect combination of clear and naturally warm. When the orchestra performs "West Side Story," the dynamic jolts were fully reproduced--the PS1000s are state of the art in that area.

Ultrasone Edition 8 headphones sounded very different with the same recording. First, the closed-back Edition 8s produced a smaller stereo image, but their bass went deeper and was more powerful. The Edition 8s' weighty tonal balance, were closer to a set of full-size tower speakers. Those headphones deliver more of the gravitas of a big score like "West Side Story" than either the Grado PS1000 or the Sennheiser HD 800 headphones. Comparing the PS1000 with the Sennheiser HD 800, the Grado has a bit more bass and has much greater presence and immediacy. The Sennheiser HD 800, meanwhile, is even more spacious-sounding than the Grado, though it may be too distant sounding for some listeners.

Finally, we connected the PS1000 to our iPod to check out some uncompressed and lossless digital music. Hearing that kind of sound quality from the iPod was really pretty amazing.

The PS1000s may not be the best headphones on every count, but they're definitely the best Grado headphones ever made.

Grado is proud to introduce the new flagship of their headphone line, the PS1000. This hybrid design has an inner sleeve of a selected species of hand-crafted mahogany made by using an intricate curing process. Its outer housing of metal machined from a special non-resonant, very hard metal alloy utilizes a special processing and casting method to increase the porosity of the alloy. This combination of wood and metal insures that the earphone chamber has no "ringing" which might obscure detail or add coloration. The way the wood and metal housing moves air and reacts to sound vibrations is now virtually unaffected by transient distortions. Grado has also designed a new cable for the PS1000. The new eight-conductor cable design, utilizing UHPLC (ultra-high purity, long crystal) copper, improves control and stability of the total range of the frequency spectrum. The PS1000 also utilizes a newly re-configured voice coil and diaphragm design, resulting in unsurpassed speed and accuracy response. The cushion design creates the correct balance between the driver and hybrid housing to give the resulting musicality desired. The cushion design also makes the PS1000 one of the most comfortable to wear headphones in the world. Grado has taken all their knowledge and years of experience in controlling resonances and eliminating distortions and this has culminated in the development of their finest headphone ever, the PS1000.

Listen, enjoy and agree.

"Brilliant resolution; cohesive; rhythmic; strong dynamics; impressive bass insight. The PS1000s are undoubtedly one of the finest headphones money can buy."

"The PS1000's are finally, the first set of headphones that would motivate me to sell all the rest, because these PS1000s do it all and do it as flawlessly as I've yet experienced. The PS1000's are the very best Grado headphone ever made."
— Jason Morin, aka Zanth on head-fi.org
"I've been listening to Grado headphones for over 15 years, and I have to say that the PS1000 is the greatest headphone theyve ever made."

"Built to last and a masterpiece of engineering, they are the first conventional driver headphones to outperform Stax electrostats across the board. What an accomplishment!"
— Positive Feedback Online / Robert H. Levi
"In any type of music, at any level, this is music reproduction of the highest order which convinces both instinctively and analytically. Hats off to Grado!"
— Hi Fi Choice magazine / Richard Black
"The Grado model PS-1000 is like a statistical anomaly that comes up once in a great while, like a great ballplayer that comes along once in a generation or two. The PS-1000 retrieves all the data sent it, with delicacy, or power (as the music demands), without smearing or masking. I think they are the Willie Mays, Derek Jeter or Peyton Manning of Grado headphones."
— Positive Feedback Online / Max Dudious
"For a sense of the instrumental separation that the PS1000s can deliver, go no farther than Rodrigo Y Gabriela's version of "Stairway to Heaven". As a bridge out of the slow intro gets going, there is a lot of fast chord work happening on acoustic guitars and you can hear every string clearly. The sound on this track was amazing enough that I had to play it twice."
— AVguide / Tom Martin
"...the PS1000s are simply the best-sounding, most comfortable, and best-looking Grado headphones we've ever tested."
