This is your dogmatic comparison philosophy. Tube swapping is hardly "required" for a comparison.
An alternative and equally valid philosophy is to use the stock components provided by the manufacturer. I don't want to relitigate these philosophies here.
I would disagree, I would never make a call on a component unless I hear it in its optimized fashion. Listening with stock valves is purely academic. Any valve amp, or a dac like Lampi that can be rolled, or a phono, should be mentioned with associated valves. A TT with its ideal arm cart combinations, or with ideal isolation. Would you want someone to audition Brinkmann only with the Brinkmann arm and the Brinkmann cartridge.
You are the one being dogmatic, I have a cat.
Would you compare two carts only on one tonearm, or will you compare them on their ideally suitable respective tonearms. You could do it on the same tonearm as well, but you would have to do them on their ideal compatible arms
Kondo amp sounds better with Kondo pre
I do not know if absolare does or does not. I do know that Kondo does not sound as good.
In my previous experience I would have chosen the Absolare, but not the Diesis. After listening to Chris’ Kondo Diesis set up, I would wholeheartedly rate it as a brilliant set up and for someone with the money advise that whole set up, Kondo and Diesis included, instead of the Absolare.
