Aurender n200, talk me out of signing on the dotted line

I’m loving my N200! I signed on the dotted line and 37 hours later DHL dropped it off on my doorstep!  South Korea-Indianapolis-customs-Missouri-my doorstep in 37 hours.  I was blown away!

Oh and I had no problems in installing on two phones and two pads. I’m using my NAS and Qobuz.

All the best.

Next day:

The n200 and DAC ran on repeat overnight. Still hot so I dug up a few Amperex:

1 Orange label PQ etch 436

2 Orange globe 7308 etch 100 and 728

2 7308 JAN Orange globe etch 714 723

1 6dj8 Bugle Boy Holland etch GA40L1

also has 6433 inked on glass

Insight anyone? White label PQ they’re not.

Thanks

@wlutke takes 200hrs to run the N200 in. It did go thru a rough patch at some point but eventually settled. 
For tubes why not try EH or Gold Lion? The NOS stuff is hit or miss. Been there, done that. 

@wlutke after the break in I would look into trying different cables. What’s connecting the AM DAC to the Pass amp? What speaker cables and power cords are you using?
