My 2 Cents on Bakoon has nothing to do with performance. Their is no dealer network to speak of so you have to pay Full MSRP or VERY close to it. Re-sale value (supply/demand) is horrible based on past "attempted" sales.  The guy in AZ who I think is the importer is a total RICHARD in my book.  So if you look at your audio gear as an "investment" and you dont want to get killed when you eventually flip it the Bakoon is dead in the water.  PASS Labs you can buy new with a 20-30% discount if you know what your doing and you MIGHT lose 10-15% when you ditch it which is acceptable.  50% Loss or more is not.
Well if that's the case in regard to Bakoon , that's quite a handicap to deal with in a highly competitive High End audio marketplace.  Too bad, as I noted above based solely on sound quality criteria it is considered to be  exceptionally good. It seems that the Bakoon deserves a better fate.

Hi Stephen,
Your VR integrated has outperformed formidable competition in your system in direct comparison.  There's no better way to  determine what's best other than actual listening experiences. You've found outstanding synergy in your amplifier and Nenuphar pairing. I think that's fantastic!

Through personal experience I know how superb the Elrog 300b sounds. 
The VR offers easy switching of various DHT tubes. Are you tempted to experiment with other tubes or is the Elrrog so good that you'll leave well enough alone?

If am not mistaken you can also purchase the Bakoon 13r direct from the manufacturer.  That might alleviate at least dealing with US importer.
Hi Charles,

That is a good question and one that begs the premise of my post: that the L2i-se has uncanny neutrality since but has a DHT tube pre and what tube is truly neutral?  But to answer your question, I first what to point out that there is scripture on this subject written by Srajan in his review of the VR Signature L2 se pre amp where he thoroughly compares various tubes in DHT mode.  From reading this, the tube I would want to try is a vintage WE 300b--which I think was Srajan's overall preference followed closely by the WE VT52, the Elrog 300b and the EH 50.   Since a pair of WE 300b's go for about the price of the component, I would like to try the WE VT52 and the EH 50 which Srajan said had an "hallucinate" sound stage.  I want to know what that means.  I like big sound stages.  Vinnie's favorite tube is the Takatsuki 300b.
