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.

The volumn control is really an attenuator. You are not hurting anything by turning it up louder. This also will have no bearing on tube life. Enjoy
It's no big deal.preamp tubes last for years. I have my volume control almost at full gain and the tubes are over 6 years old . Preamp tubes are not expensive to replace.
BTW you are better off with the volume control in the upper area on the dial because it is more flexible that way.
FWIW, I sometimes push my Ref 5 SE to 80+ clicks out of 104 total clicks when playing some records. Kal said I won't hurt the Ref 5. If you want to be certain, e mail Kal. He's very responsive.
Dial it up. No problems. I believe most, if not all, volume controls are actually attenuators and are more linear for stereo tracking (unless they are really fairly extravagantly designed and built) in the upper reaches.

I "slingshotted" pres together from a line stage to a TacT for years and unless you drive it into distortion, so what?
You can do the same thing from a tape deck with volume controls or by setting a phono pre a bit hot.
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's not really that loud since the recorded signal is low. It's about as loud as 11:00 on most standard CDs. (Rock)
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.
Czarivey, oppo list the output at 2.1 SE and 4.2 balanced.

And speakers are martin logan ascents. Not the most efficient speaker around, but not terrible.
It's a live show from PBS... The levels are just crazy low. The funny part is the interviews shown between the live set are Normal, which is loud as heck at the volume needed for the music.
