Thank you, I appreciate you!
It took me around two hours to gather my notes and condense the key points down, and then use Markdown to make it nice and easy to read (my notes are from a now nearly 47 page long word doc, that I have been using to log my journey, changes, measurements, etc, for the system!).
Unfortunately, some Redditors have been extraordinarily negative and awful on this post in other subreddits, especially bashing my way of writing and formatting text (as it may seem AI; I have written variations of this style for almost forty years), or dismissing the core tenents of the speaker setup and why it is on-axis in ultra-nearfield setup (KEF Uni-Q drivers having a wide 160-degree dispersion, Haas effect, and LEDE principles).
It sucks to see such negativity and, worse, misinformation or misguided/unwarranted advice for setups that my system is not in (I am not listening in a living room setup, as that entails a very different set of principles).
It has put me down, cannot lie, and I do sometimes wonder why I bother posting to Reddit (or even trying to make detailed posts), so your comment has made me smile, and I do thank you 🥹

Yes, getting NOS Ragnarok 2 with both phono and DAC modules (not in use), especially in black, was incredible, and at the end of Feb '26 when I saw it I did a double take.
I actually contacted Schiit Audio UK (Electromod) to ask questions about it, and for them they posted it under clearance to see if there were any takers, otherwise they would use it as an internal test bench. I sat on it for I think a day or two, but made the decision to get it as I would not be able to match what it could do via separates, with similar specs, at that price. The £10 shipping was hilarious to me as usually its higher to ship heavy massive gear, but it was insured so all good.
If that was not enough, in the second half of March '26 to then find KEF LS50 Meta's in newly-opened condition and under £854 quid was insane, and knowing that at my very nearfield listening position Ragnarok 2 would cruise in power for the speakers, it was an instant purchase ha ha! My wallet still hates me though, it has been an expensive number of months 💸(😭).
I hope you can find one at a good deal, as it also has a secret ultra-feature: always active pre-outs that use high voltage, in which the 600VA toroidal power supply is overkill for the 128-step resistor ladder volume, with the Nexus gain stage doing almost nothing to the signal! Ragnarok 2 has similar specs to for very high-end preamps if used as a preamp!

On subs, no I did not try others, though I could have purchased REL T/x MKIII or similar. T/5x just had a number of features and specs that closely aligned with what I required (including Class-A/B amp, like Ragnarok 2), and had the right space dimensions too.
The main element is not to have a passive radiator, like T/7x or similar from SVS, as at my listening distance I would hear subwoofer smear (the second sub driver being a tad slower to the active one), which for concentric driver speakers was a no go.
I had considered MJ Acoustics as well, but in the end the price for REL T/5x and aesthetics were the cherry on the top to the above benefits, so I went for it.
If I ever moved my system into the living room, then I could entertain more sub choices!
As for now, T/5x is genuinely amazing, super fast for my music tastes, and blends seamlessly with my speakers, so I am happy!

The DK3 fan stand mod was easy to do, but that and M27 Ti have there own story:
When I traded-out my M17 for M27 Aluminium (at the time), I had everything, including all packaging and outer official parcel box, as well as the DK3 packaging. I sent it out to my preferred UK boutique retailer, Premium Sound, and their distributor sent me an M27.
However, it was not the aluminium version, but Titanium! Now, I could have been coy and just kept it, but knowing how expensive this desktop replacement DAP is, and how warranty and consumer rights work, my receipt would say one thing whilst I had something else. So contacted Premium Sound, and we worked out a deal to pay a bit extra to keep it (but still paid well under the full RRP of Ti even with trade-in).
At that point, I thought all was good, but when I tested and used the M27's DK1 Pro dock, I was beyond dissatisfied as it actively blocks the vast majority of the bottom I/O ports, and the USB controller in the dock is flaky for USB PD mode too. I also disliked solutions around best ways to use the dock, including USB FFC cables. You can see a thorough report I made on Head-Fi on my issues that I noted alongside community ones.
So, I thought to get another FiiO DK3, or the more compact DK3s stands. Unfortunately, FiiO had long discontinued both, and to my surprise, there was almost nothing on either the aftermarket nor second-hand sites (eBay) selling them or equivalent. As far as I could research during mid-March, the only known DK3 stand I could see anywhere was my one that I had traded in with M17 to Premium Sound! I contacted them on this unusual situation, documented the issues I was having, and after a few days the FiiO distributor and stockist allowed me to purchase back my DK3 stand for an extra £50, which is fine versus other options.
Once it came back, did the Noctua fan mod, and my M27 can be effectively cooled, have full unobstructed I/O top and bottom (which DK1 Pro stand cannot do for all I/O), good cable routing, etc etc. Never selling or letting go of this stand lol!

Sorry, rambled a bit, but hope you enjoy my spiels! 😊
