Add, Change, or Delete? N801 , Krell , Wadia.....

I would add a few dozen new CD's. Then I would turn off the lights, kick back in the sweet spot and listen to this system for a few days. Oh, don't get me wrong -- take naps here and there -- get up and stretch from time to time -- don't be a maniac. Nice system.

Upgrade the 650's to 750's.

I would like to get a pair of 10Ts again, as I loved their characteristics, but they would be completely different with this system, and surely better than before. I recenlty picked up a pair of Matrix 801s and those sound phenomenal! Had a fellow AGONer over (considering their purchase) and he was stunned at the sound of the Matrix 801s. Really did sound nice, so the Aerial would be a nice tester as well!

For the last month this set up has been complete, I have fallen asleep probably half of the nights listening. That is one of the best parts!!

I would be curious if the 'upgrade' to the 750 would make any difference at all. Being $3,000, as I understand it, I know I don't need the additional power, but not sure if any other changes are made/necessary. Have you done this?

Thanks,
Dan

Upgrade the the 850 to a GNS modded 850 or 861. The sound will be smoother and fuller while retaining the detail. There will also be more warmth.

How about SACD player? Krell makes nice one for 4K.
