Quad QC24

Is there any Quad QC 24 tube line preamplifier user that may share the comments on it comparing the other brands tube preamplifiers if possible?
I red only one review but could not find any user so far
I have the QC 24P phono stage. It has those small pencil tubes too.

Very nice with my Scoutmaster and Shelter 900 cart. Only problem is it will humm a bit if you have the sensitivity set too high and it is too close to other components.

Tubes are rated 100K hours and are not rollable.
