The company Soekris was there with an integrated DAC+headphone amp. What is unusual about it is the R2R ladder discrete DAC.
I asked them how they can survive in this competitive market and they said that they actually design such products for other companies. I forget the brands they mentioned but they were significant.
I think the retail price was $1,200 (?).
Any of our European members know them?
Very nice people and I enjoyed chatting with them about their product and industry in general.
