Frantz, I thought the pointless sound and fury of my spats w/Purite on my Entreq grounding thread were bad enough, but this thread is emerging as the main contender to top it for a pointless waste of energy by all involved.
Ok the way I see it is that I think it's naive at best, and laughable at worst, to think any algorithm or filter or deliberate tonal choice can mimic so-called tube euphonic colourations. Tubes present music in a particular way that for it's fans like me just has a unique effect on brain chemistry. End of, IMHO. I'm quietly confident in a few yrs time we won't have dsp-type units that give us the option to have "tube sound" or "SS sound" and sound authentic.
Re lack of measurements. Well there aren't any, whoopy do. If you depend on measurements before you buy, you won't likely end up being a GG customer. I wouldn't be at all suprised if Lucasz has them, and just can't be bothered to publish them. His product, his choice.
I would love to see a customer get wowed by a GG demo (about 100% success rate from all the positive reports online), request a data sheet, not be provided one, and go "you know, I'm really not sure about this at all, I think I'll nab myself a Vivaldi, or a Trinity or an Msb etc instead". And walk out the door.
When I bought my Zu Definitions 4 spkrs in 2012, after the 2's in 2008, I came across the Zu Essence review in Stereophile from c.2010. It was a pretty glowing report re SQ, but the measurements were poor by any measure. Did I as a Zu customer go "ooh, time to sell them and buy Magicos". No. I didn't even bat an eyelid. Now, I know Zu doesn't get a lot of love (not the measurements, just their house sound is not for everyone), I just mention this as an illustration.
Just what is the point of all this?
