Hi Dbe,
I was thinking about purchasing a Blue Circle audio Peed Al Sea Thingee Power Conditioner in the future but I recently read about your minibuss here on AC and was wondering how they differ/compare 
The short answer is: I have no idea.

Beyond that I have some observations on Blue Circle in general:
I met Gilbert Yeung at RMAF a few years ago and he seems like a very nice, knowledgeable man. I was flying incognito (badge upside down), but I have no doubt that he is what he seems to be. One of the good guys.
I like their products. I don't own any, but that does not imply a lack of faith. He and I are business owners and we do our own things.
I have heard them in use and they work well. I have an idea as to what Gilbert is doing in there, but it is just speculation on my end... so I won't. Wouldn't anyway

He may have, maybe... (!?) the BUSSes beat on the ugly, strangely techie and humorously ingenious end of the equation. I roll on black paint reasonably well. They have PVC and silicon down to a sculpture that appeals to the geek in me.
The best way to find out is to try each one in your own setting with the pressure off. I offer a 30 day 100% moneyback guarantee (including shipping) that is a no-brainer to use. You can just let me know that you don't want it like 0.3% of my customers have done and the money is back to you.

Email Blue Circle
[email protected] and see/hear what they can do for you. Do a comparo. Write a review.
I am a firm believer that competition breeds better products from people and companies that care. It's all good.
