Audio Research SP-8 or Quicksilver Full Function ?


Hi there I have been looking into tube preamps for a while now and I have it narrowed down to two. The ARC SP-8 or the Quicksilver Full Function. I want it to look good and sound very detailed and natural with a great sound stage. I want to spend under $1000 and must have a great phono section and lots of Line stage inputs.

I was wondering if anyone had actually heard this two and Know the defferances I'm leaning toward the SP-8 and doing some upgrades to the Caps.

My System is
Magnapan 2.6R
Home made sub kit from Parts express with 10" titanic sub and 250 watt sub amp, this is an awesome sub kit.
B&K ST-140
Music Hall MMF-7 with Grado wood Platnum
B&O Cassette
Teac Reel two Reel
Sony ES CD player
Sony CD Changer
Senergenic Research .5 M between Turntable and CD Player to Preamp
Tera Labs 1M between Pre and Amp
Speaker wire old Huge Fulton Gold or Kimber Kable 4pr
I have two preamps now A
B&K pro 10 mc and a Dynaco Pat 5

The Pat 5 actually sounds much better then the Pro10 With much better inner detail in the soundstage and more musical sound
I have been told by many that the Preamp is by far my week link. and I should go with a Tube preamp with the True Ribbons in my Magnapans
I mainly listen to Vinyl I have over 2000 lps
I know I also need a better CD player or maybe SACD player soon also

PS Don't give me more idias for preamp that don't have a Phono sections and don't have many line inputs like everyone seems to always do.
I have rulled out the MFA magus, Audiable illusion 2b,c,d,3ect. Counterpoint, Sonic Frontiers ect.

I wouldn't rule out the SP-6 either. I have had many of the Audio Research preamps, sp6- sp8- sp9mk1-sp9mk2 sp11. They all do a nice job. Of all I like the sp6-sp8. Each version has had many changes and depending on which revision you are looking for there can be some differences. Hopefully this doesn't confuse you. If you can find a clean sp-6 tha'll be a nice addition to your system.Check all dealers that have sold Audio Research for many years and you may find someone trading up. Check Natural Sound in Framinham, Mass. They sold many peices over the years and occasionally get trade ups of all the above ....Good luck

AVA's new (brand new, this month) (SLR) version of the Transcendence 6 pre-amp will eat, in tranparency, dynamics, and tonality your other choices, and @ $799.00. Add their outstanding phono section @ $200.00. With plenty of inputs and a 30 day money back guarantee (which you won't use)... The transcedence 7(LSR) is worth 4 times its price, easy, if compared to the sculpted aluminum "Neil Fey" chassis crowd. The newer AVA top products simply disappear. Let your ears judge.
I've had about every pre-amp and line stage that Audio Research has sold....I would say that the best phono stage is in one of the three of these, Quicksilver Full Function, Audio Research SP-3A or the SP-9 MK lll.....They all have there high points but are very close in detail and price.....
