I have little more to say than these are without doubt the best 211 valves available at any price.
I’m not sure how many of these limited edition silvers were made, but I suspect you’d find them hard to find now. Not cheap, I know… but quality never is!
I bought these new directly from Elrog in Germany last October and have literally only used them to test they work correctly (and they do!).
If you own a 211 amp and you want the ultimate performance, you have got to try it with these. I can only describe the sound as truly holographic. Once you have these on your amp, you’ll wonder how you managed to live with your previously inferior sound.
I’d say these silvers sound slightly better than the regular ER211 valves (see my other listing), but there’s not that much in it IMO.
