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

Hello All,
I’m coming up on 40 yrs in this hobby,and or obsession of ours,and I started with a pair of Khorns and Macintosh at the age of 12 and Offcourse owned a ton of different gear over the yrs.
I bought a 2170 a little more than 6 months ago and I enjoyed it so much that I quickly realized I don’t really need anything else,solid state,tubes,or even dac’s anymore.I could step off that silly merry go round of amplification and just enjoy music.I was able to utilize the extra money and time and put together a really great sounding network audio system that rivaled the best in analog that I have ever had,I was mainly a analog guy all of these yrs but finally gave it up,I even sold my longtime record collection of 3k records which included many Hot Stampers that I purchased and also several that I found on my own.

So who Luv’s the 2170 and is maybe also thinking about the new 3400.

Happy Listening,

Has anybody drawn a conclusion over the PSU of the 3400/2170 claiming that no external filter or conditioner is required? I am in the market for a conditioner but before I pull the trigger I'd like to figure out if the 3400 truly doesn't benefit from a conditioner.  If Lyngdorf and conditioner advocates are correct, then the former is essentially claiming that an filter/conditioner isn't required (to a degree), and that the users find that adding one increases the sonic performance by a margin.  Then I ask myself what buying a 2-4k conditioner will actually yield...any thoughts?
I find my 2170 loves a balanced power isolation transformer based conditioner in front of it. 
As I am not using my Lyngdorf 3400 currently as much, I am going to invest more into my headphone setup. My 3400 is going for sale. If anyone is interested, please let me know. Comes with the digital and analog modules.
