"I'm thinking of trying to build the K and K Trio. I have a Dynavector 20XL on my WT Amadeus. Rest of system is Ultraverve Premap, Bryston 4BSST, Vandersteen 3A Sigs. Currently using the Van Alstine phono stage which is actually very good. "
I'm very familiar with your equipment. If you would be willing to consider an alternate approach, I would start off with an Aesthetix Janus. Its the Calypso line stage and the Rhea phono pre in one box. I have a 20xl myself and can confirm that its a good match with Aesthetix. After that, swap the Bryston for an Ayre V-5. It will be a huge upgrade from your current system, and can easily be your last. Most Vandersteen dealers sell Ayre and Aesthetix, so you shouldn't have a problem finding a demo.
