How low can you go? HELP?

[psyopwak]

Help me pick the right sub-
Pick from the list and tell me why it is
your choice. My budget is under $600
If you have another you like. I will consider it as well.


a) HSU STF-3
b) HSU VTF-2 MK2
c) OUTLAW LFM-1
d) ADIRE RAVA

I want a very "musical" sub since I will be listening to music
mostly and only movies occasionally. Tightness is more important
than total depth in low frequencies to me. I listen to Diana Krall,
Alison Krause & Union Station, Jackson Browne, James Taylor, Eva Cassidy, Dead Can Dance, Dave Matthews Band and Natalie Merchant

I have receiver- DENON AVR-4800
speakers- PARADIGM MON 9 (2)
speakers- SNELL E-5 (2)
center- BIC dv62clr
cd- ARCAM 72T
dvd/sacd- ???

I am going to make the system all Paradigm or all Snell very shortly.
Also taking reccomendations on a good DVD/SACD
player for around $600 as well. New or used.

Thanks
