Do tubes matter beyond gain stage on preamp?

So better to have a couple tubes vs no tubes.

ie. Harmonic distortion is highly desirable vs flat ss.

ashame they dont insert tubes in an av processor.  I run av sound thru a tube pre and it sounds incredible.

+1 but don't expect a troll to provide details of a made up comment.

jperry, how r u?  Even if made up it would be good, its not. So add somethin or go away.

It depends on the topology of the preamp, as to how many tubes are used. 

well, if i had a client with a tight budget, i would advise gain stage first….but in my experience they all matter eventually as ratchet up performance across the system.

Can hardly wait to get the tube power supply for my….wait for it….direct drive turntable….
