More true to the original? If the component is meant to do something other than amplify, if it is a form of EQ, noise removal, compression, limiting and so on,
by definition it isn't true to the original and
the manufacturer of that component will be the first to tell you so.
I've no idea about the Weiss- I stay well away from Stereophile. I've seen JA blow measurements out of the water, although usually he's pretty good. The Audio Precision device he used in the mid 1990's was supposed to measure with either single-ended or balanced but apparently didn't support AES48... I don't know if Audio Precision ever fixed that. DACs have been one of those things that have changed like the wind- you can pay a lot for them and a few years later can buy a new DAC on ebay for $125.00 that sounds better and measures better too. Digital was always one of those things that if done right, you really shouldn't hear a difference between one and another, yet here we are 40 years on and that's yet to happen. I regard them as a poor investment due to their ephemeral nature. Useful though, just like underwear, but you lose a lot when selling used
But to be clear, I regard a DAC as a source rather than something meant to modify, in much the same way that a turntable is a source, or a tape machine. They are fundamentally different from an EQ or reverb in that regard.
My reference has always been recordings I've made myself. I have LPs that I mastered and I set up the microphones before the tape rolled. I know how they are supposed to sound because I was there. When I started doing this, I started out trying to sort how a reference can exist, so I started with direct microphone feeds, listening to actual musicians and then listening to what the feed sounded like played through headphones and then a system. I found that everything made a difference- the mics, their placement, the mic preamps, the amps and speakers and headphones. None of it is perfect although a mic feed can be so good it can easily fool the most jaundiced audiophile- I've seen it happen and been fooled many times. When the signal goes to any form of recording or processing that spooky nature of being so real is usually lost.
So if you want to know what my goal is, I want that spooky character where you suddenly realize that someone got into your house while you are playing your stereo and is singing really well along with your stereo- and when startled- you look and no-one is there. That can happen with recorded media but its rare. When it happens it makes it all worthwhile. IME the only way to get there is to keep the signal path as clean and as simple as possible.
