They're all very good suggestions:
- The Pass Labs Int-250 was in my short list together with the Hegel H590
- The Vitus RI-100 is an excellent suggestion at around $6000. I read the suggested review and a couple more. I think it is a winner.
- I like the idea of getting a new DAC since 100% of what I listen is streamed. I was thinking the Pontus II of even a Terminator II. I have to research the Aurender and the Innuos to see if there is considerable difference. I'll do that after I upgrade the Integrated amp.
- I'm using 2 REL subs T5/x at very low volumes. I also tried the Dirac with the NAD M33. It doesn't do too much of a difference in my room. I actually think it is better with Dirac off.
I just want to say thank you again to all the suggestions and comments.
