Not to test the ‘money no object’ but to show what an end game SS supply could look like; a current driven amp with a small Hoover Dam backing it up ‘power no object’ Jackula on these blogs, introduced me, he has one:
http://www.audio-gd.com/HE/HE-9/HE-9EN.htm
“Summarize Built in regenerative power supply Uses three R-core transformers (In total 260W ) and more than 100,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery. Separate class A PSUs power supply for regenerative drivers ,Left and Right channel audio signal amps . Total applied 8 pcs exact matching 150W transistors ( In total 1200W )  as the output stages  for implement large class A output power . Uses most Hi-end grade parts and exactly matched transistors, OCC wires. Four-channel 100 steps digitally controlled relay-based volume control avoids channel imbalance and improves sound quality . Supper Exponential Volume Characteristic,  easy match the volume with very high headphone / speaker without change the gain mode. 20DB gain can drive the low sensitivity headphone very well.”
Many other lower cost amps will take you beyond your GSX1000, and I’m sure other HE4XX owners will chime in.
Edit; Your GSX1000 gamer has a low power processor in it, to be kind; not too impressive:

The Audio-GD R-28, one I have been considering, is something that will give you an R2R DAC and gobs of power to drive the HE4XX's at a bit less $$ than the Hoover Dam level HE-9 (amp only): http://www.audio-gd.com/R2R/R28/R28EN.htm

AckerIf you have the money... leapfrog all the in-between hardware, save yourself while there is still time —- go ~mid-fi, it’s a wonderful place, get something like this R-28 and go for 24/96, 24/192 FLAC & DSD files; http://store.acousticsounds.com/c/372/DSD_Download?gclid=EAIaIQobChMIzpuXnYTJ3QIVDV8NCh0oPQWJEAAYASAAEgKKkvD_BwE , get a player - examples; Roon ($$), Jriver etc. to bypass internal windows crap, nice white paper; http://m.marantz.co.uk/DocumentMaster/master/Marantz_DAC_White_Paper_6th_March-2018.pdf
You will actually save money, time and frustration in the end...

USB has issues... but best we have right now... a fix: https://www.adorama.com/cc10mtusbcbl.html , don’t fret about the length, it’s optical - photons;) coil it. (adaptor needed for DAC side)
Or... get this stack from MD right here... I have suggested that they offer a bundled package; aesthetics, versatility and performance / at a palpable price...

rastusI received my R-28 about 3 weeks ago and still burning in (24hrs on). It's also burning in my new 3 day old dynaudio studio monitors at the same time and I think i achieved my end game for a few years.
That being said, Im already thinking how i would stack an HE9 to my existing setup cause the power regen stuff interests me to a great deal.

HeavyboxerNice,, I was going to go for the R-28 but changed $ plans to get a 300B SET for speakers, a quest for the Siren's Song, that is also incredible with cans btw. The R-28 is also current driven, like the HE-9 with nice reserve power, just not the Hoover Dam Regenerative "no mountain (peak;) too high" level of the HE-9. Interestingly, I see my 300B SET as being somewhat analogous to the HE-9, by having a secondary massive capacitor bank, to handle the transient power requirements, normally deficient in a SET amp.
So how does the R-28 deliver in regards to an "organic live" signature, what files are you playing with it, native DSD? I went with the Denafrips Ares R-2R, in the mail from China, looking forward to this experience. Hopefully end game for me for a few years also;) I was disappointed that the R-2R from MD/Airist skipped over DSD native capability, really... the bias or whatever it is, is strong.... For an SS amp, the HE-9 is also on my list.
Yes, nice looking table top racks for these mid-size units like the GD's, are a missing item in the marketplace... the stuff that is out there is like - crazy custom price level... why you see the DIY oiled wood/threaded rod/nuts& washers... which done right is not a bad look... MD should really package price the THX/R-2R/CTH... the market is there and ready to buy... a calculator, a few keystrokes, upload, and see how it ticks...
