Best Sounding Passive Preamp


What is the best sounding inexpensive passive preamp? I may have to send my preamp in for repair which could take a while and I don't want to be without music. My top priority is sound, but I don't want to spent a lot of money as I will be putting my preamp back in system upon return. Help please.

This must be a bit new, $300 more though, should keep the tube lushness guys happy.

I guess I must be one of those tube lushness guys. I already own a Schitt Asgard headphone amp, which impressed me enough to act like a Math guy and try the passive pre/tube combo, just in case!

Slowhand, if I might intrude, thanks in advance:

M Brown, I own the SYS. Currently use it with a Dynaco ST-70. Have not compared it to my Jolida Fusion all tube pre in my primary system.  Also own the Schiit Valhalla all tube headphone amp. Would like to know what you think of this new Schiit passive/tube active.
