Who has Luv for the Lyngdorf 2170 and is thinking about the 3400.

Great post @bullitt5094!  Our digital front end is so important. I applaud you for all the work and time you gave this test.  Wow!   I learned a great deal from Kenny and through reading. I will add these points. My front end is much like yours it seems.  I also use Roon. 

- you really need to add both the Audiophile Optimizer and Fidelizer if using a computer server. I cannot overstate the Sonic importance.

- my computer uses a Nice SOTM USB card - SOtM txUSBExp - that I power with a nice linear power supply. Do not let that card be powered by the computer! A quality linear power supply is a must. Huge SQ improvement.

- I use the IFi Micro USB 3 and it is my digital MVP tweak! This must also be powered by a nice LPS. Very, very important. Your DC cable quality is also very important folks. Make one using Canare Quad Core cable and Oyaide DC connector.

- get a great sounding USB cable. The Phasure LUSH or the one I make. Yes I can make you one. Kenny is now testing it.

The front end is the MOST important way to get the most out of your 2170.

I use current and usually turn it up quite a bit.

Bullitt5094,
My name is Kenny and I haven’t used the I7 in quite a few months,in fact I sold it about 5wks ago,I probably overwhelmed you with my jabbering.

Anyway It’s all about the sound and whatever works the best for you,and I’m damn proud of you for trying different stuff,that’s the only way to know for sure.

IfI the winner,That’s odd to me,but I still respect your decision regardless.

Happy Listening,
Kenny.

Aniwolfe,
I usually use default or 30 and I have experimented higher too,
I don’t think it really matters as long as you are close.

Somebody else may have a different take then me though and I always try to be as open minded as possible.

Kenny.

Well Kenny you know I love my Ifi Micro 3  USB also 😉.   See my above post.  You have been a great help to me!
