Vinpic,  Just a Heads up concerning Valvet. Some prefer the Original 2 over the SE model. Original is suppose to be sweeter. I probably made a mistake myself ditching the 1st one before listening to it to get the upgrade. The SE will run you around 4K...you can get the regular used for about 1200.  Just something to consider and potentially save some dough
Thanks Riaa. It’s on his way... 🎶
My Sound|Kaos Vox3a are lined up for the Valvet, will also try it on the Nenuphars and revert with thoughts.  
@vinpic,
Thank you for your reply, I now more clearly understand the passive Icon replacing the Vinnie Rossi active DHT Line stage. The analogy comparing the Bakoon13R and S.I.T.3 is very effective and clarifies their different sonic presentations.

Very interested in your listening impression of the incoming Valvet amplifier. I saw elsewhere on this forum you’ve had the Ypsilon integrated amplifier. You have certainly had/heard your share of really fine quality audio equipment. Sound Kaos? Nice! I look forward to reading more of your posts.

@david_ten, 
Thanks for asking. Yes, pretty much, especially when stephen dunn chimed in and said that his Vinny Rossi integrated sounded even better when he put resistors into lower the damping factor. Still curious about the Bakoon. I have not been able to find a figure on the web for its damping factor, but it's unique Satri circuit could have something to do with it. Seems like low damping factor is a good rule of thumb, though there may always be outliers.

Keen to try your resistor solution for the VR L2iSE.  Can you pls share model of resistor Vinnie recommended, how to install, any precautions etc.  If you could add a photo that would be great.  Thx!
