Accepted and I apologise. I am sensitive to shilling and some dealers do 'announce' gear on here in public posts. It was the price list inc shipping that sent me off on one LOL.
Back to the OP, I do think the R-2R sector is very active right now, and in a good way. There is a healthy DIY group building discrete R-2R DACs at real world prices as well. I would love to have ago, but would look to fit a tube regulated PS and tube line stage to support a discrete board. The Soekris board is 230 USD, and you could probably set 2K USD max in parts for the rest inc chassis for a tubed DAC.
Well, if it makes any difference, I couldn't sell my Lampi fast enough, so I did...and no, I didn't pick up a Metrum Adagio. I bought a Linn Klimax DS/3.
However, I am very interested in what Soekris can do with their R2R. You an pretty much get these for a song. Implosion? Yes...but in a good way.
