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.

I owned a Primaluna Dialogue Premium and preferred the 2170 over it. It all comes to taste and system synergy. I still like tubes, but if I ever went back I would get a SET amp not a PP Tube Amp. Just my opinion and good luck. FWIW 3400 does not use a DAC if connected digitally only with the Analog inputs.
Stereo5,
If snackeyp doesn't ultimately prefer the Lyngdorf to his Prima Luna he will occupy a rare position. Based on owner feedback the Lyngdorf exceeds nearly all previously owned components.  Room perfect seems to be a very significant factor for overall performance. So it will be interesting to read his listening impressions once he utilizes this important feature. I don't doubt that the Prima Luna and  Harbeth 40.2 sounds beautiful.

Snackeyp,  thanks for posting your initial impressions.   I’ll be interested to read your thoughts as you listen to it with different sources.

Couldn't disagree with @stereo5 more.  You can't judge an audio component until it breaks in (and you break into it), so if you simply judge it on first listen you're not even close to evaluating it fairly or accurately.  I think you're very smart to listen without room correction first.  After 100-200 hours of breakin you'll have a very good baseline for the performance and character of the amp on its own.  My guess is that if after that breakin point the Lyngdorf is even in the general ballpark of your enjoyment level with the Prima Luna, the room correction (properly implemented of course) will smack the ball out of the ballpark.  Room correction, in all but the most meticulously treated rooms, can be HUGE and can overall greatly outweigh the differences between two electronic components IME, but of course this is all room and equipment dependent.  In any event, I'll be very interested in what you find as someone who is also very interested in potentially becoming a future Lyngdorf customer.
