Well I haven't got a good answer for you but I do have a word of advice. Equi=tech isn't exactly an "audiophile" company so if you do compare the products I would strongly suggest trying a decent power chord on the equi=tech. The BPT folk provide a nicer one with their products and so the comparison is a touch skewed out of the box. I would be a bit worried about all of that silver wiring (I believe) in the BPT. I personally use the 1.5Q equi=tech and find that sitting it on a good shelf not just plunk on the carpet and putting a decent cord on it (cardas golden ref, Blue Circle 62 (i think), audience power cord) makes it a good relaxed, get out of the way and let the shading and detail come through without over emphasising. It also helps give a little more definition to the soundstage and images without over-doing it. I like it.
Hope that helps
