Audio Research or Conrad Johnson Tube Pre-Amp???

I am looking at the purchase of an Audio Research SP-9 or SP-14 or Conrad Johnson PV-9a, PV-10, PV-11 or PV-12 pre-amplifier. It's very difficult since I've not been able to hear every one of these pre-amps. However, I do want a tube pre-amp to mate with my Threshold S/300 and Mirage
OM-9 speakers. Later I plan to purchase Magnapan 1.6 speakers. I will also be using an Elite Rock Turntable with Excalibur tone arm. I will also be using two professional tape decks for recording and playback.

I really need assistance regarding the following:

1. Which pre-amp will work well.
2. I also need to know which tubes are the best for a particular pre-amp?
3. how long do tubes last normally with 2 hours daily use?

Any other information you can offer would be greatly appreciated. Thanks so much all.
4. Does turning on and off the tube pre-amp hurt it?

There is a rating on the HIFICRITIC web site, they have tested most of their preamps and keep the ratings current.

I suppose downunder refers to the location of your head so you should know bullshit when you see it.

Downunder, when I want your opinion I will beat it out of you. Martin Colloms has been one of the most respected Audio writers for over thirty years while you are just some shithead.
