It will be a shock to many that a pair of £1,700 headphones arrive in such a shoddy white box. It is plain cardboard with foam inserts.
Grado are a relatively small family run business, so the presentation is sadly lacking as they put all their time and effort into the design and creation of the headphones themselves. It may bother people used to Sennheiser packaging, but we can live with it.
When the headphones are removed, there is an extension cable and a 6.35mm to 3.5 mm converter cable.
The PS1000 headphones are really very heavy, especially when compared to the wooden GS1000i's. They do however look absolutely stunning. Like the GS1000i set, the phones have an 8 conductor cable design with high quality dynamic transducers. Grado claim that the control and stability of these phones is unsurpassed throughout the range of the frequency spectrum.
The cable is reassuringly thick and is held in place with a substantial support. It ends in a 6.35mm gold plated plug. This is an extremely high quality cable as we would expect at the price.
The PS1000 is a dynamic transducer design which works on an open air principle, with a frequency response of 5hz to 50khz.
The GS1000i by comparison have a frequency response of 8hz to 35khz. Both phones have a 32 ohm impedance rating with a matched driver db rating of 0.05.
Both sets of phones are supplied with the oversized cushion design implemented by Grado many years ago for this range.
The idea is to create a ‘room’ for the ears to sit inside, which in effect creates a larger soundstage and greater spatial awareness. Grado spent many years working on fine tuning the balance between the driver and the housing to create the desired end result. Finding the sweet spot was painstaking, but they claim to have found it.
Give me a break !
Do you need any reviewers? 🙂 please ?
I read KitGuru daily, I wanted to add that I think these reviews are great and I enjoy reading them. I am an audio fanatic and have been for 30 years now. My naim setup has cost me an arm and a leg and I have never adopted CD yet due to the harshness Zardon describes. This was a very enlightening and entertaining review and thoroughy enjoyable. You have made me want to try this setup and also pick up mike oldfieldds remastered discs
Finally, I was getting disheartened trying to find a decent review of this amplifier and today I find one.
Do you think the amplfier works well with Sennheiser I have HD650 headphones, not the 800’s. whats your views on this pairing? I use chord cables also, as I think they are lovely and warm? views?
Grado are spectacular. I have a set of their 125’s and love them. they come from New York too, so im biased :p
Someone who has a taste for classical music ! so uncommon on sites such as this. I normally read reviews of headphone and speakers tests with some 18 year old reviewer using his oasis 160kbit mp3 compressed recordings of wonderwall as a guideline.
refreshing, well written and inciteful. thank you.
Any idea if Graham slee export their amps to USA?
Been hearing a lot of good things about Graham slee on forums. But 600 is more than my cd player and headphones put together
Chrome finish? Bet that’s a total nightmare to keep clean, looks great mind you. Like the Harley of the phone world.
I need to contact Graham Slee and see if he can ship to Australia. I hate the sound of my headphone amplifier.
I also need to look at Grado phones, but probably something like the RS1. these are out of my price bracket.
what a brilliant idea and pairing of equipment. never heard of graham slee, but he seems active on his forums which is a nice thing to see.
Those headphones are works of art !
I have heard the Ps1000 headphones in a studio environment. they are mindblowing, but extremely difficult to power correctly. very demanding of the partnering equipment.
That Graham Slee amplifier has a hell of a wide support range.
Well I have eyeing these headphones now for a long time and this review just made me bite the bullet and hit the credit card. I only got them yesterday so I’ll let you know how it goes over the next few weeks. Thanks for answering my emails zardon you were a lot of help.
Could you please tell me the difference between the Graham Slee Ultra Linear and Ultra Linear de? Thanks you.
I love the new vented diaphragm!
