Yes I am the one that picked up the Bartok. This past weekend my friend brought over a bunch of his gear and we had a mini meet. He just picked up a fully upgraded MSB premire stack and brought is new Traformatic Primavera and formula s.
The Primavera is really amazing with the abyss. It is the best that I have ever heard it sound. With the MSB it was incredible. I can not afford this combo though it is in excess of $50k for the amp and dac.
That being said we listened against his Dave and mscaler combo too. In the end I am glad that I went with the Bartok it is more to my liking ( I would really like to get the rossini but $). I have no intentions on upgrading my dac for a good long while now.
He did let me keep his formula s to audition for a while too. The formula sounds incredible with the abyss and Bartok.
Here is a photo from the proceedings. Please forgive the traformatic on the box and the Dave on the floor ( we did move it to a solid surface for listening.) The traformatic is huge though.
