I thought I would share my own thoughts on the Golden Reference Discrete Regulated Power Supply, to give it its full title, so GRPS hereafter.
A separate dedicated power supply for the Gilmore Lite MK2 (GL2) headphone amplifier. This must be rare for amplifiers in the sub $1000 price range. The only one I can think of is the AUNE XPS-1, but that is in a lower SQ league.
The GRPS comes in a black case identical in size to the GL2 and with the same tank-like build quality. It neatly sits on top, or below or side by side if you prefer . The lettering on the front panel matches the latest design of the GL2. There is no on/off switch, so it is designed to be powered up permanently. The top of the unit is perforated with relatively large holes from which a red glow emanates from the components inside when powered up … it looks like it means business but runs just lukewarm to the touch. My unit has a white power light, which doesn’t match the amber one on the GL2 that I have, although I believe that a matching colour light can be specified at the time of ordering. I just forgot to ask, but to me the sound trumps looks.
I detected that it benefits from some settling down … the sound became more refined after a couple of days, or so.
The GL2 with the standard PS is already a worthy performer but the GRPS brings some notable and worthwhile improvements and these (IMO) are not merely small differences. From my notes …
First off, the soundstage … wider and noticeably deeper. Sound-levels are clearly commensurate with where the instruments are on the stage, front to back. This results in a pin-sharp image of of the instruments.
There is an airy ambience that adds to the realism of the sound. The detailing of the instruments is impressive with fine nuances revealed. Even the decay is well detailed … then it goes to complete blackness.
All frequencies are well represented. In particular the detailed low-end is remarkable. One can almost feel the low frequencies, given the right recording … the E string on a double-bass or electric bass is articulate and easy to follow. The B string on a 5-string electric bass is visceral but perhaps not to bass-head levels. Everything is, however, well balanced.
The GRPS finally realises the full potential of the Gilmore Lite Mk2 amplifier. It must be closely approaching the quality of its bigger brother, the GSX-Mini, albeit with just an SE output, which is fine by me.
Full marks !
Music: Jazz, Classic Rock and some Classical.
