Which Hegel are you on? The H390 max res is 32/384 through USB … if you bought H190 which is much less expensive then yes 24/96. You are a victim of not doing your homework and possibly financial limitations.
I just read a report on an independent lab that tested the H390 and the results comply with what my ear hears … the H390 is an amazing piece of equipment. Source was HiFi news.
Your complaint is equivalent to buying a 718 Porsche Boxster and then complaining because the 911 Turbo is faster and has more horsepower … both are beautiful but the complaint is without merit because it was a self imposed limitation.
