#1 Yes, using analogue out from 808v6 so no MQA light but assured of MQA performance. ASP 0 setting gives a well balanced presentation. ASP 1 and ASP 2 tend to push soloist (both instrumental and vocal to the fore) however some recordings benefit from these settings, some don't. Conclusion ASP is a nice to have.

#2 I have owned Grado Statement Range GS 1000 for approx 5 years purchased new. Also Grado GR10 earbuds. Both Grado products are easily and satisfyingly driven by the Prime Combo, they are both very comfortable for long periods of use.

#3 2 Years +

#4 Yes, still very satisfied with the price paid.

#5 Difficult question but Yes is my answer today. In future years I would look at available alternatives and available funds, audition / compare and decide. I don't think I will be in the market for replacements anytime soon, unless I win the lottery, tempus fugit.
