Not sure if this is of any importance, but Golden Gate from this picture in particular is the one I use daily. It was upgraded to balanced version and got silver front changed to black one.
In any case, I previously owned two-box Level7 and moved from there. Yes, LampizatOrs aren't pretty inside. At least a good while ago (2 years back) that was the case, not sure how it is today. But this I know: this unit was purchased somewhere in September 2015 and it works flawlessly ever since. It's on duty eight hours a day, five days in a week and is never completely switched off. This is the best DAC I've heard thus far. Additional bonus is that LampizatOr HQ is about 15 kilometers from my place and the man who does them will do any fix needed if something bad happens. He's solid, I never had any issues when I wanted to upgrade my unit. IDK, maybe that's me only, but the ride thus far is enjoyable.
As for DAVE, it's a great DAC. I believe that I could be very happy with it. I never had an opportunity to compare it to GG. But after hearing it several times in various places, usually with Utopias, my bet is that it's less showy and not this feisty, hence different. Still, it seemed to be quite balanced sounding with no obvious downsides.
Just my two cents.
In addition, I see that people diss LampizatOr a lot here and, to be perfectly honest, I understand why. The company is still one leg into DIY and its price tags are heavy. Overpriced products? Quite possibly yes. But the most important thing for me is there, I enjoy what I hear.
