How hard is this on a tube pre amp?

I have an audio research ref2 mkII going in to a proceed hpa2. You know those low signal channels, the ones that sometimes you record awesome live shows from? Well.... I feel kinda uneasy cranking the pre past 12 to 1:00 on the dial, but 3 sounds prett dang sweet.. Am I driving the crap out of the tubes?

It's gotten better, ( louder signal ) since going balanced from the oppo 105. But still, some things really have to be cranked.

wow how loud do you need??
ref2 already seems to be a high gain pre, but turning it to 3:00 -- chances you're hard either on speakers or amp.

It seems to me that you have a lack of input level and using player with weak signal.
There are players that have 2v output and perhaps you should look for the one instead of what you have.
Your volume settings past 12:00 should realy shake the house while moderate volumes should between 9:00 -- 10:00 or 10:00 -- 11:00
Your tubes in preamp pretty much 'don't care' about your volume settings. Oppo players have only 1v output.
