Lyngdorf TDAI-3400

Well, after reading all the rave reviews of the Lyngdorf TDAI-2170 both here and other places, I decided to order a TDAI-3400 for myself.  I must admit I am still skeptical that such a diminutive piece of equipment can sound better than the Primaluna Dialogue Premium HP tube amp weighing more than 50 lbs, but I have been so intrigued by everything I have read I simply had to pull the trigger. 
I just unboxed it today, hooked everything up, and am listening to it for a while before setting up Room Perfect. 
I really want to hear the what the amp sounds like as-is for a bit to understand it better. 
First impressions:  Without Room Perfect it sounds like very nice solid state amps I've owned in the past, but to be honest, I don't find the sound to be particularly moving.  I moved to tubes after years of solid state, and I swore I would never go back.  That is where I'm coming from.  I should also add that I always try to keep an open mind.  While my initial take on it might sound like I don't like it, I hope folks just read this as me being as honest as possible about what I hear.  I know the tendency when buying new gear is to want so badly to love it in order to justify the expense that it's easy to fool oneself into believing it's an improvement over what you had before, even when it's not.  Of course I really want it to be as mind blowing as it has been built up in my mind to be, but if it's not I am OK with simply moving back to what I have liked so far.   
I have only been playing records through it so far.  Analog makes up 98% of my listening so that's where I am starting with it.  I have a nice CD transport that I will connect to it in the next day or so just to hear the DAC in the unit.  I will also experiment with playing files from USB sticks, computer audio from my MacBook Pro, and whatever else I decide.  I am not prepared to purchase a music server just yet, but it's something I have thought about for a while.  
My system:  speakers are Harbeth Monitor 40.1's.  Turntable is an SME 20/2 with SME IV.iv tonearm and Kiseki Purple Heart cartridge, fed to a Parasound JC-3+ phono preamp.  Power conditioner is Audioqest Niagara 7000.  CD transport is a Wadia 8.  
I will report back as I have more time to experiment and let the amp break in.

Well, similar to the OP, I tried the same thing again the next day and mysteriously, it worked. There was nothing different about this attempt but somehow it was able to detect the microphone and I was able to launch Room Perfect. 

I will say though that I reached out to Ellington Hifi and Tony got back to me within a few hours. He then tried to reach out to me by phone multiple times during the day and we finally connected later on in the day. Though I was not his original customer, he treated me like one and his effort to help did not go unnoticed. Just a stand up guy, Tony is. I wouldn't hesitate to work with him in the future for anything he carries. Just thought I'd put that out there. 
Is there any place nearby the Washington DC area to hear either of the Lyngdorf integrated amps?
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.
Hi very interesting reading. I was searching for reviews of the Primaluna HP integrated and stumbled on this discussion.

I am looking for an amp that can deliver a huge 3D soundstage. Can the Lyngdorf deliver that? In the France review the soundstage was being criticised for staying between the speakers.

 But from what I am hearing here you all think that the soundstage are very good.
I purchased the Lyngdorf TDAi-3400 from @waltersalas and am just starting to familiarize myself with the amp.  I moved from a Devialet 200.  Look forward to sharing thoughts!
