Package arrived … 
I propose we hold off the shipping for a week or two just to make things exciting! 
  Try to get some sleep! 
Aeolus I like the Novo with the HD580 and HD600 a lot. Where are you located? Send me a PM if you are interested.
Up for your consideration are two units by Red Wine Audio, both in 9.5+ condition using the Audiogon scale. I also have the original boxes and materials received from Vinnie. The units are about 2 years old.   1. Isabella LFPV Edition with both the USB and the 24/192 DACs including the balanced headphone out. This unit retails for $7,000 plus S&H, I will be including an OCC cable to convert from the balanced out to 1/4" made by Vinnie and which retails for...

RFI is an issue with a lot of electronics, personally when I have an iPhone in use close to the amp (couple of feet) I can hear noise.
IMO the LME49720HA is an outstanding sounding op-amp and in many applications the best.

I have also replaced the volume pot with a cheap attenuator from eBay, see pic below.

Of those the AD8620 sounded the best but not necessarily better than the NE5532 just...
