here's my two cents. I was looking at the HSU VTF3 my self for HT & music. I ran across articles of the PSA15. after much research comparing the two, I decided to go with the PSA15 ported sub. my deciding factors were the basch 500 watt RMS amp over the HSU smaller 350 W Rms. yes the HSU has a higher short term power of 1400w, but I'm of the old school belief that RMS power is a better standard than total peak power. The psa has no delivery charge. So both amps price out the same. From what I had read, I fill that once some comparisons come out on this sub it will come out tops in it's price range. so I decided to get the PSA15V. I can't give you any comparisons, none of my friends have any thing to compare this to. I will say that I'm happy with the performance of this sub. My sytem composes of an emotiva xp3, Wharfedale 10.1 speakers and a 12" ported non powered sub. I have a large open floor plan with 15' vaulted ceilings. I have not had a chance to test this sub with a THX movie yet, but the indications for this PSA15V are good.
