@charles1dad Indeed, I first heard about the duelunds from you and as always found that I heard the same thing when I put them in my system. I've currently got them on my pre tweeters and as output caps in both my dac and pre. I've tried a number of different caps and never heard better. I'll certainly update with some details of the Radu Tarta (Shiny Eyes, simplepleasuretubeamps) build. Thanks for all your posts, you're one of the few people with whom I find perfect opinion overlap when I try the same equipment. So valuable to have that information.
@mresseguie I made the updates in a number of steps. The only one I can't totally disentangle is the impact of the silver wbt rcas (installed concurrently with the solid core silver signal wire). The primary upgrade I'd suggest is the output cap upgrade. I know a lot of people like the miflexs, but I found the duelunds to sound better in every way. I also preferred mundorfs to the miflexs, which just sounded flat and two dimensional in my system. Both duelunds and mundorfs produced much better 3d imaging. You can read a bit more about all my cap comparisons on my system page (I wrote a lot due to boredom).
It's more involved, but next I would consider replacing the stranded duelund signal wire with a solid core alternative (I use vh audio solid silver in cotton). People correctly talk about the wonderful tone of the duelund wire, but I have found that stranded wire blurs the imaging. My three DS inputs have the vh audio silver, stock duelund, and a single strand of the stock duelund run through a Teflon tube (you don't need 16ga speaker wire for small voltage preamp signals and tiny wires work just fine, see phono hookup wire, for example) so it's easy to do comparisons. I believe anyone listening to my system would be able to immediately distinguish between the three and would prefer the silver wire, then the duelund single strand, then the 16ga duelund. Again concurring with Charles, the solid core silver sounds more real than copper to me. I replaced all my amp, dac, and internal speaker wire with solid silver too and have never regretted such modifications.
