The GH2 has replaced my RS2e (both with G Cushions) as my "to go" and primary Grado Headphone, nice soundstage, great bass for a grado , maybe not the RS2e "Detail Monster", but i love the sound signature, engaging, live, fun, universal, from classics or jazz to techno or rap. ... but this is...

bmichels - you can replace the potentiometer by two resistors, but should not just remove it, because the resistor(s) together with the Input capacitors work as high pass filter limiting the lowest possible frequency (see http://www.electronics-tutorials.ws/filter/filter_3.html f.e) (the cut off...

Dear Shikada San, great to see you here, a big welcome from Germany!

Just saw this on ebay - one used GH1 available:   http://www.ebay.de/itm/Grado-GH1-High-End-Kopfhorer-neuwertig-aus-2016-/162456588962?hash=item25d32ad2a2%3Ag%3A4E0AAOSwdGFY4p65

  Playing from internal Storage - never faced this Problem, playing from micro sd Card - it was a bad Card, changing the Card was the solution.

(one time) Slow during indexing / updating the Music library, but in any other aspect works fine (10k files on two 128gb Cards, x3 xduoo Firmware).

GRADO RS2E PORTABLE: RS2e with Philips SHL3565 Headband and Wireworld Silver-Nano Eclipse Cable, fits into a VModa Crossfade M100 carrying case (xduoo x3 for size comparison).

My xduoo sometimes just needs a reset, seems the device sometimes looses some bits of the firmware, my xduoo swapped left and right channel, also it happened that left channel had no signal, after reset everything worked fine again.

  Had the same problem, finally have started reading and learning opamp and tube amp design and have designed and build my own portable tube amp(s) especially designed and finetuned for grado headphones and 32 ohm Impedance, big soundstage and my sonic preferences. Details are posted here:  ...

Tried grado flat, l and g cushions ... Some time ago listened to the previous version of the ps500, it's not my cup of tea, i definety love the sound of my two rs2e (for office and home) with g cushions, the rs2e has replaced my gs1000e as primary headphone, and while i love the engaging sound...

Just for fun i bought a 14 years old sr325 (no i, is, e), no impact, bite, sparkle, sounds totally boring and lifeless, seems the drivers have reached the end of their lifetime cycle.

No isolation from external noise!
