Dk Design VS-1 mkII what tubes are you using??

I believe I was one of the first to buy a DK amp, I own the MK I version ( I took a risk and purchased it for $1000 new on ebay and had it shipped from the USA to Spain when there was absolutely no info available on the internet - in fact, I think that the first post here on Audiogon was mine!) I am still happy several months later. I use the Siemens CCA tubes. I like the slightly more neutral sound that they provide as opposed to the lusher richer sound you get with other tubes.

As a follow up, last night I was listening to a wide variety of music on the DK unit.
This Integrated,(I almost feel blasphemous calling such a precision piece integrated, as if it somehow diminishes its performance)--makes music fun again.
It does not 'clarify' things...it does not give 'more slam' it does not give any of the prototypical audiophile descriptions of performance, it just works, and better than my list of well knowns, Krell, Mac, Ayre, AR, cj, (sorry Bill and Lew), et. al.
All bets are off. At $3K don't hesitate; it has the power in my thousands of cubic feet room to fill it with sound, and it's music.
Peter Cincotti, Rod Stewart, the movie D'Lovely, are all rendered wonderfully, and in a way I thought had been lost in some ways, with all the techno babble, and advancements, we're back to the basics. It just sounds right.

Good to know, mine should be here next week, I have some PW amperex e88cc's to try.

I replaced the Amperex 7308 us orange globe gold pin tubes I have been using with nos Siemens CCa 6922. The CCa tubes are as stated by many more before me, amazing. I hear a sweetness to vocals that makes me listen to many songs over and over. The bass is also incredible. I am still considering Amperex pinched waist down the road but for now enough audiophile madness. I am going to be spending my time listening and buying some new music instead of worrying about changing gear or tubes. Thanks to everyone as always.

Congrats, get off the gear changing, and get into the tunes. Enjoy to music.
