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 will add that digital room correction is a mixed bag. If the software is trying to heavily boost a null in the bass then it could easily cause your amplifier to clip in the bass even at modest volume levels.

+1. My thoughts exactly. @JCarcopo, perhaps the unit is working as designed, but the room correction function is doing exactly what Shadorne is saying.

I know that the DAC circuit at the output of the DEQX HDP-5 I use as my preamp can be clipped if any bass frequencies are boosted for room correction by more than about 6 db, depending on the frequency content of the music. In my case, though, exactly what the HDP-5 is doing for room correction, at every frequency, is visible and adjustable manually, via a computer that can be connected to it. Does the 3400 provide visibility into the characteristics of the corrections it introduces?

Hi Waltersalas,
I’m looking forward to your upcoming listening impressions with the system maneuvering you propose. You make an exceptionally compelling case for the Lyngdorf, that is for certain. The LM 608ia provides those elusive "goosebump" moments (which I totally understand).

If further burn-in time and fine tuning tweaks could very possibly get the Lyngdorf to the "goosebump" level. If so then overall the Lyngdorf would be the superior choice. Even without the "goosebumps" the Lyngdorf exceeds the  LM 508ia in several very meaningful sonic parameters. Again I thank you for your always clear and very descriptive writing.

@charles1dad I hope to get some response from Lyngdorf very soon. Hopefully they will swap units, but I fear the Lyngdorf is boosting certain frequencies which is causing the clipping problem.  If that is the case I'll need to reposition the speakers and hope to fix the issue with placement even though its well nigh perfect in my room atm.  I will say when it's playing properly and not clipping its amazing sounding at higher volume levels.

@shadorne I hear ya loud and clear. I fear this is the issue, which really sucks.

@almarg Yes, and I hear you too. Again, this really sucks!

@waltersalas I'm just having 1st world problems.  I'm certain this can be rectified.  I will remove my whining post. It's not helpful.
