Tekton Double Impacts

My decision was always going to be a SS amp, but my decision to go with a clad D amp, did not come easily. Truth be told, I am (was) a class D bigot. And I don't mean a bigot for class D. I didn't want anything to do with it.
As I mentioned, my primary use will be HT. I am working with a person that has professionally worked making commercials, so he knows about the HT sound and how the sound steering should work. Quite interesting actually. He is the one that steered me to the Anthem processor because he said he thought it did the best job of moving the sound around seamlessly between where it was supposed to go. He also recommended the M27 to me. I respect what he told me, but I thought to myself "you can't be serious, with all that is out there."

I started reading as much about class D amps as I could and the M27 specifically. I could not find anything bad on the M27, and some comparisons were to some pretty expensive amps. I also did speak to Dennis at D-Sonic since he is local. His amps put out much more power. Most of the people I spoke to about his amps had good things to say. In the end, with myself finally convinced that I could not only live with but like a good class D amp, my friend promised me that the dynamics of HT would be superb and that the musicality of the M27 was excellent. So that is going to be my amp.

I just googled M27 review and this came up http://www.soundstagexperience.com/index.php/equipment-menu/636-nad-masters-series-m27-seven-channel...
I've actually read better, but this review is pretty typical. Yeah.... it surprises me too...

Evolvist,
You are most certainly right, all amplifiers regardless of topology present some degree of tradeoffs, this is unavoidable. Super low distortion as a result of utilizing NFB then introduces the unwanted higher odd order distortion (5th,7th and 9th) that Ralph (Atmasphere) has described often on this forum. It’s always going to be some form of compromise/tradeoff to content with. Best solution is to choose what sounds right/better to your ears and accept the fact that it is not perfect in every sonic parameter,  nothing is.

@evolvist and @bullitt5094  Great to hear Bullitt's system is coming together. Looking forward to hearing more about the SEs once they are fully run-in.

@vitop  I'm pleased with the NAD M27. And it is frustrating that it is sitting idle while I wait for my HT system to take shape. Like you, I've been impressed with it's reviews and performance in my system. And like you, I will probably have the Anthem AVM 60 in front of it. But I wouldn't choose it as my go to amp for 2ch, as long as I had choices. For that, I have a very clear lean towards Class A/B and now finally a Class A amp in the Pass XA30.8.  Your response to 333Jeffery made me think it would be good to get it back in system and see how it does, now that my system is more 'mature' and better dialed in than it was when I had just received the Double Impacts.

Just for the record, I have nothing against Class D amps. In fact, I have nothing against anything in the audio world unless the sound turns me off. 

Evolvist, the Ulfs now have over 100 hours on them, and they are still breaking-in. If I had to call it right now, I would say the DI's get you 75% of the way to the Ulfberhts. But this can change as I put more hours on them. I am using the Yggy dac, and it seems to pair well with the Tektons. One thing I can say for sure about the Ulfs is that they respond very enthusiastically to power, much more so than the DIs. My dad put this to the test by playing some of his classical piano cds through them, and cranking up the volume to thunderous levels. I'm talking heavy metal concert levels!  The Ulfs didn't once strain/distort/compromise the sound quality. The piano sounded amazing, almost like having a concert grand in the room with us.
