Bakoon: to correct some misunderstandings.

The Company is run from the USA, with manufacturing at this time in South Korea.

If you reside in the USA then contact Bakoon directly.

In Europe contact your local Bakoon appointed dealer. If you are in the U.K. and would like to try please let me know.

As someone who is casually looking for a Bakoon 13r - the resale market is no way a 50% drop. I've seen on average about 1k off from 6k MSRP which is a pretty standard discount in terms of a listing price.

In terms of dealers can't speak to that.

If I purchase a unit new it will likely be through Bakoon themselves. 
If you do purchase a Bakoon 13R  amplifier and have the time (And inclination) would you post your listening impressions? I believe there are folks on this thread who’d be very interested.
Absolutely. Will do. This is the best thread on agon. Might as well contribute here ! 

For reference I've got the LTA Ultra Linear right now powering some Tannoy Eaton speakers (dual concentric). From the sounds of it in this thread I think it's safe to say the UL is similar to the FW SIT variety (in the ball park). A tube change to some GE model tubes has made this amp exceptional
Miraculously this thread has avoided agitating trolls, keyboard warriors and rude and disrespectful behavior, what a welcome relief.
The LTA Ultra Linear compared to the Bakoon 13R is very interesting as there’re such distinct differences between them. It’d be fun and informative to hear them driving your Tannoys or the Nenuphars. As this thread has substantiated,  there are numerous good quality amplifiers to consider pairing with the Nenuphars.
