My new VTV Audio Class D amp arrived today

You weren't tempted by the tube buffer?

twoleftears,
I was, but figured my tube preamp would enough.  The tweaks offered above look interesting so thanks for the share on that.  

I have maybe 30 hours on the amp and honestly sense very little difference in SQ since the time I connected it to my system and have run it in.  I am really impressed with the crystal clarity of the music, along with very large soundstage and tonally very balanced top to bottom.  I got the Sparkos op amp, recommended for a softer musical presentation by Warren.  At the moment, I am enthralled with the sound of the amp in my system, but will swap back my McCormack amp as means of comparison after 100 hours.  However, at this point, I am of the opinion that this amp is a huge advancement in the art of Class D amplification, very different than my past experiences with Red Dragon, Nuprime and Bel Canto, although I am sure that all these Class D companies have greatly stepped up their game since my audition of their amps several years ago.   More later, but I am really happy with what I am hearing so far.

How would you compare the $979 VTV Purifi amp with the $150 ac mod to other class d amps in the $1500-$2k range with no mods?
