    I purchased these tubes for my Quicksilver Audio line stage preamp. I wasn't sure what to expect, as my preamp already provides great imaging and detail and I was skeptical that a noticeable improvement could be gained. Well, I was WRONG, as the improvement in overall sonic character was immediately noticeable. The bass is actually tighter and more defined, which was the last thing I expected. In addition, the soundstage seems even more detailed and clarified, and the highs/mids/lows sound more pronounced and separated if that makes any sense. In short, these tubes have made the single biggest impact out of any changes I've made, including intereconnects and speaker cables. I could not be happier, and it was the best investment I've made on upgrades to my system.
