Clabe, I agree with Bobby on the Mundorf sound. I've tried the Mundorf Silver oils in various places in my system, thin out mids and brighten highs. I've heard the Mundorf golds are a bit better in mids. I will only use Mundorfs as replacements in my Merlins. I should have my Duelund copper foils in tweeter position in the next week or so. Next to Duelunds, Hovlands sound best in Merlins IMO.
