User Experience on Aqua 274B Rectifier Tube

Hello,

I recently discovered your Aqua 274B and I liked it, no, make that LOVED it, enough that I purchased a second one as a back up. This after trying, and I'm not exaggerating, at least 30 different rectifier tubes in my Lampizator DAC. It is an amazingly musical and enjoyable tube. 

So let's just say I'm now a big fan of your company. I am intrigued by the Magik Box and am considering purchasing the open box unit on your web site. Based on the reviews I've read, I expect I will love it, and I will know very quickly (in the first few minutes) whether it's a good fit for my system or not. My question is, if I decide after a one-day trial that it's not right for me, can I return it for a refund? 

I seriously want this thing to become a permanent part of my setup -- but I need to know I can return it if I'm not impressed. (I suspect I will be.) If you say yes, I will place my order immediately. 

Thank you,

Kevin
