While a passive can be easy to build one that does not degrade the sound is not. Especially one with a cheap pot. My high output tube pre with a cathode follower and low Z out was always used to attenuate my sources. It never provided gain. Connecting my source to my sensitive high Z input amp could easily overdrive it. An unneeded gsin stage will provide no benefit. My pre was a nice CJ with lots of tweaks like coupling caps, ps upgrade and a power cord and IEC inlet as well as nice black plate tubes.

I'm trying a pre, now, and can easily max out the volume. Average loudness maxed out (depending on source's recorded volume) is 100dB.
My opinion is that I like it. It sounds beautiful. But I'm not sure it's any different than the P5 I used previously, other than having much lower overall sound level capability. Basically...I can't decide, yet, if it's a good setup.
Thanks for the help.
If you go balanced XLRs I see no issues. Using RCA's not so much.

The pre does not have a balanced option. I'm using 2' BlueJean RCAs, now.
Do you say this because of the difference in input impedance of the amp between these options?
Not only the amp but the DAC too. Its output doubles balanced. Im saying if you get a passive get one that is balanced. there are plenty of all types that have balanced connections (XLR) Your preamp wont be used anymore then.

I read a post in a forum about the Lightspeed volume control that suggested that a balanced system would not be as good (more noise, blah blah blah)...
ahhh...that makes sense (I think). Many thanks for the help. I'll try out a balanced pre and see what happens.
You guys are great!
Yes and get it from a place that will let you return it if youre not happy with it.
