I've wanted an Aguilar DB750 since I bought my Aguilar cabs (410 + 2 112's). I love their sound and have heard only incredible things about their amps. I'm using a BMAX with a Carvin power amp and I'm pleased with the sound so far. I also own an SVT-II Pro which I'm planing to sell soon. I like it's sound but the weight is just to much to handle. The problem is that as I did with the cabs, I can't try before i buy that amp. I live in Puerto Rico and no store sells Aguilar here. Here's the thing, I've seen a couple of used DB750 on ebay and other online stores, but i read somwhere that the 10-year warranty is not transferable to a second owner. Is this true??? If so, would it be wise to buy a used 750 w/o a warranty?? Sorry for all the writing but I want to know about this issue. Thanks for your time and feel free to comment on the amp if you own it or have tried it.
