OK… Time for me to move on elsewhere. As stated in my first post.
Let the flaming / excuses commence 
Jk and I both share the same passion as does all of us here. We are just a big family and we all are independent individuals. The discussions are that and not worth fueding in my book. I like to learn every time I read a post and it doesn’t disappoint.
I think both of you are fundamental resources of this forum! Good luck for your journey even if on different routes, anyway in parallel!
Memory can indeed fail. I suspect most of us have had this experience.
Unfortunately, every other method of making a subjective judgment, such as what component or wire sounds best, is similarly fraught with failures.
I find it best not to make a decision as to what component/wire/tweak is “best” until I have evaluated it on many levels and in multiple ways over time.
Along these lines, it is intriguing how often DACs, preamps, amps are described as “bright,” “recessed,” “dark,” etc. when they all measure within a fraction of absolutely flat. Something other than frequency response is at issue. For example, the component judged bright does not have an elevated high frequency response.
Or maybe the use of different components can make things sound bright where others do not however on paper they look like a good fit.
Just find out who compared what…
So far I noticed only Vmax found the Mk II brighter in his setup and you so far didn’t compare Mk I to a Mk II because you decided not to buy it for the moment, correct? Or did you meanwhile have a chance to hear the Mk II?
One doesn’t need to purchase to evaluate.
Also in my reading I found many more who found it bright sounding. Also many said you have to move the speakers to FIX the brightness.
Yes I am NOT purchasing the MK2. Waiting for the TSS as stated several times.
Yes sure, so you had a chance to compare to someone else’s Mk II…didn’t notice it so far…so you have first hand experience.
Have you read what I posted?
I had both the MK2 and my DS with the big Jensen’s in my system and A/B them.

Are you indicating the use of thin film resistors actually tips the high frequency response upward from flat, or that there is something about the sound of thin film resistors which a listener may interpret as “bright”?
I really don’t understand.
What I thought to understand from your post was that you didn’t buy one but you had another chance to hear one. Not sure if you think I criticize you, which I don’t. Just wanted to find out if you heard one.
Your own boss picked thick film resistors in the opamp circuit over thin film in the DS as he liked the sound better.
Please read my post. It explains everything.
Yes, placebo, expectation bias, etc. is potentially involved with any subjective judgement - including real-time A/B.
Thus I suggest evaluating the impact of any component in as many ways possible before reaching a conclusion.
OK… Sounds like a plan however you are wrong about real-time A/B testing if you do blind testing and level matching. (no one knows what source is being listened too).
I am comfortable stating no one with whom I work has any knowledge of resistors whatsoever. 
Back to my question: Are you indicating the use of thin film resistors actually tips the high frequency response upward from flat, or that there is something about the sound of thin film resistors which a listener may interpret as “bright”?
I’d say things a little differently: the thick film resistors sounded bad everywhere except when setting the Vocm for the opamps. So arguably with the initial DS release he liked a “fuller” bass sound. Thin, vs, thick would make no difference to the high frequencies where they were used. With later software updates this is no longer a good idea. Thin film resistors sound better everywhere in the DS to most of us.
thick film resistors sounded bad everywhere except when setting the Vocm for the opamps.
Yes… That is what I’m talking about in my statement. I never stated where it was used and what effect it would have. There is a proper place for the type of components used and they all effect the sound. Some look good on paper and don’t sound as expected.
Maybe that was a bad example.
A/B/X testing is fraught with many dangers and is often misapplied/misused/misinterpreted. It is not a panacea.
But it is a valuable tool.
Nope, this particular statement is yours:
This is why I asked you a couple of times whether you were asserting "the use of thin film resistors actually tips the high frequency response upward from flat, or that there is something about the sound of thin film resistors which a listener may interpret as “bright”?
