Is no preamp really better that a good preamp?

It's not really about the specs, although impedance matching should be considered. Go back and read Atama-Sphere's response. Pay attention to #3 and #4. IMO If you do not need the gain, the source variable output section can control the interconnect, and you like the sound then you should stop there.

I am at RMAF and saw the bespoke passive preamp that George posted the link to. It is quite a piece of art, has very smooth input selection and 47 step volume control, and both balanced and RCA connections. Unfortunately cannot judge the sound because it was only on a table display. Based on the view under the hood I can say it is well manufactured with proprietary wound transformers but at the price point it sure makes me pleased I own high value passives like the Lightspeed and Slagle AVC.

Milpai, I have had a TVC using S&B transformers and now have an autoformer unit. As you know I am a fan of passive preamps in general and also own George's Lightspeed. They are all a bit finicky to work with but in the right system are great devices. I have been fortunate to have such a system.

However, a couple years ago I found the need for more gain in my system due to my increased use of analog vinyl and tape sources. So I turned to an active preamp for that purpose, and in my case one that is quite transparent. I still use my Lightspeed in a digital system I have set up, where it works flawlessly.
