ARC SP-6 Warmup time
Not familiar with that unit but 10 minutes does seem excessive. My cj premier 16 took less than a minute or so. Currently my Herron phono stage goes through the same start up sequence and takes less than a minute as well. Chuck 
How long daes it take your gear to warm up?
About 45 minutes ...... 
Tube Preamp/solid pwr amp or solid pre/ tube pwr
Well I am in the camp of tubed pre-amp with ss power amp or go all tube. I have used a cj tubed pre along with cj ss amp to drive Thiel 3.6's and it was a great combination. The ss power amp can get a better grip on demanding speakers more than tu... 
Need info on amp rec. for these Thiel cs2.4's
The direction I would take with any Thiel which wasn't totally clear in my last post was a tubed pre-amp with a ss power amp. Thiels really seem to like this combination. 
Any way to "improve" a Conrad Johnson MF 2500
Is the hum coming from the speakers or the amp? The transformer in the 2500 does have a propensity to hum.If you placed the stone on top of the amp it is probably dampening the cover which in certain circumstances can amplify the hum.Chuck

I was using Thiel 3.6's at the time along with a premier 16lsII pre-amp. The amp became more detailed and faster while retaining the typical cj 2500 sound. It did require about 20-25 hours of burn in. The non A version smoothed over the details of...

When I had mine upgraded it cost $500 plus shipping there and back; well worth it. Chuck 
what is a good tube pre amp out there...........
I use all silver cabling (HGA) as well and find it to be very transparent and organic sounding; not harsh in any way. I also use NOS tubes in the Cary and the sound is very open and detailed and smooth.

The tube store or tube depot http://thetubestore.com/ or http://www.tubedepot.com/ to name just a couple.Chuck

Upgrade it to a 2500A if it isn't an A already. The "A" mod improves the amps speed and detail. You have to send it to cj to get the work done but it is well worth it and while it is there they can go through it.Chuck 
what is a good tube pre amp out there...........
Kennesawjet understandable and fun to do and if you buy used and don't like it you can always flip it. I am using a Cary SLI-80F1 integrated and love it but cj is great as well. Based on your comment about ARC it sounds like you like cj and would ... 
CJ PV-14L replacement tubes
Not sure what tube that model uses but you could roll a couple of different Manufacturers and determine if there are any differences. If that model was like my PV-10 you just remove the top and the tubes are right there just pull them out slow and... 
what is a good tube pre amp out there...........
I went from a PV-10 to a premier 17 then on to the premier 16 and in each case the improvement was dramatic in all areas. So I would suggest you stay within the cj line if that is the sonic character you enjoy. Cary makes outstanding tubed preamps... 
Can 12AT7 be a substitute for 12AU7 tubes?
In most circumstances I would say No .... I would ask the manufacturer of the component in question.Chuck 
Need info on amp rec. for these Thiel cs2.4's
I ran a pair of Thiel 3.6's with first a cj MF2500A and then a cj premier 350 both worked great and were ss offerings from cj. I used a cj premier 16II tubed preamp in combination with the ss cj amp and the presentation of was very smooth and deta...
