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?
I have been a big fan of CJ's Premier 10. Owned three, still use one in the HT set up. Affordable, huge soundstage, not too warm. Also check out the Motifs... best of both worlds.
