Tube Preamp shoot-out


I'm in process of buy a tube preamp that has HT pass-through to add to my HT system. I've done some ressearch and narrowed down to BAT VK-5i, Audio Research LS-25 and Sonic frontiers Line 3 which available in the same price range(used). Now I would like to know "What will you choose among those three?"

My current HT setup:
CD Transport : Audio Research CDT1
Processor : EAD TM Signature
Power Amp : Jeff Rowland 5
Main Spkrs : B&W Matrix 802 S3

Thanks,

I'm a big S/F Line 3 fan.. I've got one and love it. Yes on the HT pass thru, yes on the most outstanding remote both ergonomically and feature laden,yes for a superbly neutral sound (tailor your system w/other equip. or accessories...) and yes for both single ended and fully differentially balanced inputs and outputs... not to mention exceptional build quality and reliability. A top performer and exclnt. value. To me, it's an easy choice. Good luck
Supakit, I have the EAD Ovation Plus and I also have the SFI Line 3. It is nice set up. The Line 3 is the best for music. The only problem I have, and it could be only with my system, is when I use the HT pass thru, I get a noise that is like whisper from all speakers, it's some kind of interference, it is very annoying especially at quite scenes of the movies. I have been trying to get rid of it for sometimes now, but I couldn't. Even thu I have the PS-600 that is powering all equipment with the exception of the SFI Power 3 amps and the CRT projector. I have tried different cables, power cords, different outlets, nothing worked. My understanding is EAD is very sensitive. So my advice is to try them together first. I would appreciate anyone who can help with this noise I am getting.
Why no one has considered Cj. Try the Premier 17LS - its a killer at that price esp. used at Audiogon. I feel the Rowland 5 with B&W 802s + the cj 17LS will be a killer combo! The musicality of the cjs are top class.
A word of caution about the Kora Eclipse... I owned one for over a year and I loved the sound with my 2 Plinius SA-100 amps. However, I had a serious problem whenever we had a power failure and the Kora was turned on. The 4 input fuses in each plinius would blow. These are a real pain to replace. I tried all manner of power conditoner/supply changes, but ended up switching to another pre-amp when neither Plinius or Kora folks could identify the problem.
