Recently purchased the Grado PS2000e headphones. I have used them for about 25 hours for the past week. I've never been much of a believer regarding the effects of burn-in other than one's ears getting used to the sound peculiarities of new headphones. The gear used to drive the PS2000es are as follows: Mcintosh MCT SACD/CD Transport, Mcintosh D1100 DAC/Preamp (connected to transport with supplied umbilical cord to maintain SACD capacities), Mcintosh MHP100 headphone amplifier (using the low impedance high gain setting; no bass boost was used with this amp), Black Sand Cable Black Max Series Violet Z1 MKII power cables all around, and Moon Audio Black Dragon balanced interconnect cables. Paid full price for them at Sound Components, a local dealer here in the Miami area.
There are bad and good things about the Grado PS2000e headphones:
THE BAD:
1. Ergonomics: except for the headphone drivers and maple wood used for these headphones, the design is exactly the same as that of the PS1000s and the rest of the Grado products. I have never liked the Grado design. The "coat hanger" wires that hold the drivers are not practical at all, specially for heavy headphones like these ones. The phones tend to slide down (one side was much less secure than the other one...while one stayed in place, the other one slid down. Quality control issues at play here!). I ended up bending the two coat hanger wires to one side to create resistance so they would not slide anymore. While I was able to solve the problem, it should not have been a problem in the first place.
2. Weight: these things are quite heavy. They are heavier that the PS1000s (at least they feel that way...I also own the PS1000s). The wider head band does next to nothing to ameliorate the comfort issues (actually, the PS1000s are more comfortable given their lighter weight).
3. Foam Pads: make the headphones feel uncomfortable. The ears end up touching the surface of the drivers, thus creating friction and lack of comfort.
4. Cable: the headphone is just too short. While Grado has supplied a high quality headphone extension cable, I am afraid that slight sound degradation due to the added connection of the extension cable could potentially be at play. By the way, I got these headphones single-ended (there is the option of balanced termination).
THE GOOD:
There is really no reason to be wordy regarding the good things inherent to this pain or headphones:
1. Treble: extended, no grain, smooth, no sibilance. This is possibly the best treble production I have heard in a pair of headphones. I also own the Focal Utopias, which have great treble, but the Grados are, to my ears, slightly ahead in quality of production.
2. Mids: not too prominent, not too recessed. The mids sound just right. No V-Shaped curve here. Amazing mids that do not bleed into the magnificent treble presentation. As good (at least to my ears) as any Audeze, but without the thickness. Euphonic mids, but never goes over the top. In the same league as the Utopias (maybe a bit more euphonic), as far as I am concerned.
3. Bass: best bass Grado has ever produced in a headphone. Definitely not a headphone for bassheads (that's what the Fostex TH-900s and Audezes are for), but excellent bass nonetheless. Layered, excellently-controlled bass that never bleeds into the other frequencies. I listen almost exclusively to classical music and the bass is just perfect for my "predilections". Compared to the PS1000s, it's no contest. Better bass than the Utopias (note that with loud timpani and bass drum strikes in orchestral works, the Utopias splatter a little).
4. Soundstage: the best soundstage Grado has ever produced in a headphone. Not huge (a la Sennheiser HD800s), but not smaller-than-average either (a la Focal Utopia). The soundstage sounds extremely natural (not exaggerated or slightly artificial, like the HD800s). Just perfect for classical music, as far as I am concerned. Voices sound just perfect (not too distant, not too close) in opera recordings. Male voices excel, but female voices not too shabby either.
MISCELANEA:
1. These headphones are classical music kings. Better, in my humble opinion, than the HD800s (i.e., previous kings of classical music).
2. Sound-wise, there is nothing I can criticize about these Grados.
3. I had never been a Grado fan in the past...this changes everything.
4. The most balanced (top to bottom) headphones I have ever heard/owned (take a look at my profile)
5. Fast transient response. Airy. Highly detailed, yet at the same time euphonic. I don't own (or have heard) the Stax headphones, but I can't imagine them sounding better than these.
6. These are one of the few headphones that sound great at low volumes (Grados are kind of known for this); for instance, the Utopias have to be played at high volume levels to get the best they have to offer.
7. Mr. Grado strikes me as a stubborn man. The ergonomics of this pair of headphones are really holding them back, in my opinion. If these drivers had been assembled in a design similar to the HD800s or Focal Utopias, then we would have THE HEADPHONES.
8. Expensive, but for the sound alone these are worth every penny.
