Suggestions for a tube preamp


I am looking for a tube preamp that will work well with my system:

Clayton S 40 ampliflier
Rick Reimer Wind River GS speakers (on order)
Heavily modified Pioneer DVD player

I do not need phono and do not want to spend more than $1000.00 used.

Here are some preamps I have looked at:

AR LS 7, LS2, LS1
Blue Circle BC 21
Sonic Frontiers Line 1
MFA MAGUS
Audible Illusions L1 or Mod 3
CJ PV 10
Counterpoint 2000, 3000

Any and all suggestions will be appreciated!

I thank everyone for the responses so far.

TWL, MFA is out of business. Is there anyone that can service this unit if there is a problem? I have also heard that this unit is better when modified.

There is a MFA Magus B for sale on AGON right now. Any info on this unit would be helpful.
Yes, the MFA products can be serviced and upgraded by one of the original designers, Bruce Moore, through RB Audio in California. I bought my preamp from him and the upgrades also.
Hiflyer if you get a chance listen the Aronov LS9000. I replaced a AE-3 with one and I never looked back. Just for your info the AE-3 replaced a LS-7. I thought the LS-7 just didn't cut it. Best of luck on your search.
The Sonic Frontiers Line 1 is an excellent sounding full featured pre-amp (no phono). I use the Line 1 in my 2nd system and have also used it in my main system very successfully. IMO, it is on par with the more expensive Line 2, and is even better when you find tubes you really like. Cheers. Craig
You should also consider BAT VK3i at that price point, esp. if your amp can handle a balanced input. It will accept s.e. and balanced, and provides both balanced and s.e. output.
