Matching preamp to amp

Dave,
More would never hurt. I'm not sure about 50V but typically tube preamps do swing larger voltages than solid states.
I'm SS dude but CAT is on my most tube likes!

Daveyf, Read your question again then read my response. The CAT has the same output as Audio Research preamps that matches your D-70. Actually the ARC SP-8 is a matching preamp for your D-70 and has a maximum output of 60 volts, but you won't be using the 60 volts you will be attenuating your source.

Did you try the CAT and D-70? Maybe you should try it and let us know what happens.

Thanks Rrog, I haven't yet tried the CAT/ARC combo, but should be able to next
week.I will post as to the results.My current setup of CAT/Jeff Rowland model 8 works very well together, although I can set the input impedance on the model 8 to accommodate the CAT.

BTW, Marakanetz I agree that the CAT rules..:0)
After having listened to many preamps, both ss and tube, the CAT is here
to stay.

Well guys, I hooked up the ARC today and it worked very well with the CAT.
Unfortunately after about 20 minutes there was a VERY loud cracking sound
and i think one of the tubes ARC'ed ( pun intended).( Luckily I managed to mute the output before it blew my speakers...whew!) At first, I thought it could have been a bad cap, but my tech seems to think it was a tube gone bad..:0(
Oh well, back to the drawing board...
Any ideas as to the problem?
