Thanks so much for the responses. I'll pick up some of the JJ ECC88 Gold pins since they aren't too much money and give them a go. Thanks ZenGentleman for the info on the DAC upgrade. I do have one more question since you both use the Multibit Bifrost. Is it a big step up from the regular...

Good evening, Does anyone have opinions on Amperex 6922 from 1951 or New Genalex Gold Lion with gold pins? I am looking for some new tubes to try. I am also open to suggestions. I currently have a matched pair of the OTK 6n23p/E88CC from the early 80s. My setup goes PC>Bifrost 4490>Valhalla...
