Im putting together a system and need help

Hi there, Where to start. I have a reasonable budget and some decent gear to start. I hit hard Times and sold most of my gear and am looking to rebuild my system.

I mostly listen to older bluesy rock but also listen to hip-hop funk rap, not so much the typical audiophile stuff. I love tubes but cant afford what I want.

So heres what I have left after selling my nice little system

Equitech Son of Q, Furman Elite 20
Parasound Halo A23 Amp
B&W 804 Series 3
MIT 330 shotgun, 330+ an T2 interconnects
QED Silver anniversery Speaker Cables
2 nordost Magus Power Cables

As you can see I need a Preamp, CD player, USB DAC (I use AIFF Computer Audio) and Subwoofer.

As far as amplification goes I have the Halo A23 and was thinking of getting another to bridge it to 400 watts.

I would like to buy a Conrad Johnson PV11 but am poor and am thinking $450 should I get their PF-1L for now? whats good for cheap. if its $600 ill just spend $200 more for a PV11 but I need something to get me by.

I was looking into the velodyne HGS 15 or 18 with a broken amp as velodyne just 2 hours away or a paradigm servo 15.

as far as dacs I like the PS Audio Digital link III as it can me modifeid by underwood HIFI and looks good.

I am looking for solid reliablity and as much customer service I can get while still getting some great sounding gear. Also as much that is local to the SF BAY area as possible.

Please any and all advice will be very much appreciated and well listened to and researched. For the record im 26 and back on a budget and really need to redo my system.

Oh do you know of any rock solid DVD Players that weigh 30+ pounds that dont have HDMI so lthey lost all there value but will still make a great transport (Id get the 5910CI but its still $800

Oh and one more thing as far as subwoofers go. In my car I have 2 Focal/JM Labs Utopia 11" subwoofers in custom fiberglass boxes with a Diamond/Esoteric Audio D7402 Amp which retailed at $3500 in the mid 90's. How would that do If i hooked them up to a car battery with a charger and eliminated the wall noise. While its 12 volt if i hooked it up to a car battery it can pull i believe 160 Amps of current. Its rated at 400 watts x 2 @ 4 ohms in Class AB. The boxes were made by one of most respected installation companies in the business. Any way they would be ugly but the boxes were $600 a piece and the drivers were 1400 each. Would i better of going home audio sub. It seems like my amp is about as awesome of a sub amp as ill find and it has a built in crossover. Oh when the subs were made the drivers were the fastest ever made and the 13" version is in the 15K Talon Thunderbird Sub (with the most awesome box almost ever built).

Lots of questions

Thanks again, Toby
