By the way and back to the title of this thread...
In January I met Dr. Gauder at a dealer presentation of the DARC 100 and 200 with the new top of the line T+A Electronics. As I was considering trading in my Berlina RC7 D MKII with a pair of DARC 100, I asked Dr. Gauder about his opinion.
He told me that a large number of Asian customers still prefer the Berlina series to the DARC series to to their fuller sound. However, he told me that with the Black Series update, the Berlina RC 7 would make a big step towards the transparency and bass performance of the DARC series.
Due to the lockdown it took me until June to bring my Berlina speakers to Gauder Akustik. The good thing about such a small and customer oriented manufacturer is that you can ask for any kind of customization. I therefore asked Dr. Gauder to go beyond the update to the Black Edition version and get me the best available sound from my Berlina RC7... and Dr. Gauder had already some speciall tweaks in mind.....
When I went to pick-up my upgraded Berlina speakers, me and Dr. Gauder had a test run in their listening studio and the big leap forward in sound quality was clearly audible - even in this unknown environment. The clarity and soundstage was just stunning! The Berlina Black Edition speakers are a kind of mix between the Berlina MkII and the DARC speakers: transparency with body and weight.
The official name of my speakers is now: Berlina RC7 Diamond Black Edition Double Vision
Another great feature of the Black Edition speakers is the Bass Extension which boosts the low bass (I measured below 60 Hz +3-4 db). If you don‘t need this boost (like me), the amplifier even sees a simpler load which is great for my Grandinote monos.
So I heavily recommend the Black Edition Upgrade!
