I had been using an Audio Research phonoamp and was reasonably happy with the open airy vibrant appeal of tubes. Now I have always used Klipsh Cornwall’s and have never been left wanting. Until a friend was upgrading his system and he had offered me a loan of his Plinius 14 phono. I was very impressed specially in bass response, needless say I am still using it on a permanent basis. Now I do have a tube pre amp that the Plinius is connected to. The bass region is just great with just as much openness and staging.
