That is true. If you are looking for a neutral/transparant piece of equipment as some us are, it is different. If you want a colouring amplifier you will have to try many of them with your equipment. Sometimes some kind of tone controls are better/cheaper for adjusting to a prefered tonal colour etc.

Has it occurred to you that what you think sounds neutral/transparent may not sound so to someone else?

Neutral is not transparent.
You can have a "warm" sounding component that is very transparent. You can have a "neutral" sounding component that is not at all transparent.
Neutral relates to freq domain. Meaning flat FR and preserving flat FR at different output levels.
Transparent relates to transient detail and tonal (harmonic structure) and texture aspects. But not necessarily so much to FR response being flat. E.G. an equalizer or tone control can be "transparent".
Good clarification Satie!
How would you describe your listening experiences with the UCD? Which model was it? And with what equipment?
I have not had the chance to hear an up to date UcD and did not hear the early one I came across at any conditions to pass any sort of judgement.
I was interested in trying an Ncore amp till I saw the paper you linked describing how it works and implying that the sampling rate was not increased. Now I am (much) less interested.
I have a modified Nuforce amp that I used for midrange duties for a while but have "retired" it a few years back and one of them is broken at the moment awaiting repair at Nuforce (2nd time now). Very neutral transparent through the mids, great dynamics, slight grain in the highs increases the higher up the freq of the music and harmonics goes. Resolution is not really there - the difference between digital and vinyl is much reduced indicating that it is not as transparent as it seems through the mids.
I had one of the Crown XLS for 1 day. Need I say more?
"I had one of the Crown XLS for 1 day. Need I say more?"
Many on audiocircle are having a much different experience. That shows how subjective audio can be.
I haven't heard it so I can not comment-not that anyone's opinion really matters. It all comes down to personal preference.
For the price, it is hard not to give it a listen.

I know about it, that is why I tried it in the first place.
Well for me the first word that comes into my mind about Hypex is actually "neutral". I've heard quite a few amps, and one the best was my latest Luxman L505. Even though Hypex UCD costs only about 1/5 of it, I thought that it was on par with the sound quality. Not exactly the same, but pretty much as good as Luxman, both being musical but also very neutral with acoustic music.
But hey, can anyone give answer on this; which tubeamp can handle the 2-3 ohm resistance of the ribbon?
Tube amps for 2 ohms: Most of the KR audio amps. Some of the Beards, Audio Innovations has 2 ohm taps on some versions of the model 1000. And there are others. Besides you can put an autoformer between the amp and the load.
I appreciate the L505 and unless your source is restricted to redbook digital or entry level vinyl you are likely to not lose much in going for an Ncore or Wyred 4 Sound, or Bel Canto class D amps, or Nuforce whatever you want to call their amp type. It also depends on your speaker. My Vandy 2C would never have shown up the difference. My JBL Centuries would never have shown it either. With the NS1000 berilium tweeeters I put in them they definitely did show up such differences. E.G. I bought a Rotel Pre and Power amp and borrowed the integrated from the same series. I kept the integrated and returned the separates since I could not find an interconnect that made them work better than the integrated. The dealer suggested an interconnect that cost nearly as much as the power amp, I didn't even try it.
The designer of both the UcD and ncore has said repeatedly that his priority and design goal is neutrality-that the amp should have no sound of its own. The ncore is brutally revealing; what many have thought were flaws with the ncore are in fact issues upstream. Some prefer a more "musical" amp.
