I can't really be sure, because the products in the company's main page (http://www.store.abrahamsenaudio.no/) are the same like in the distant past. But, the company started selling these products this year (there was nothing in their official page until then- if i recall correctly). And the products did not appear all together. Instead, the DAC appeared last one. Many months ago, the company advertised a new series to come, called "Aeris". I finally never saw such a product line. But instead, the v1.0, v2.0, v3.0, v4.0 and v6.0 appeared on their main page. So, i have no idea, but it seemed to me as if it is an improved version of the old ones. I hope someone else knows more nformation than I do. Is there anybody that has bought an Abrahamsen v6.0 in the last month ? Maybe he/she could help us.
