Hi Charles,
That is a good question and one that begs the premise of my post: that the L2i-se has uncanny neutrality since but has a DHT tube pre and what tube is truly neutral? But to answer your question, I first what to point out that there is scripture on this subject written by Srajan in his review of the VR Signature L2 se pre amp where he thoroughly compares various tubes in DHT mode. From reading this, the tube I would want to try is a vintage WE 300b--which I think was Srajan's overall preference followed closely by the WE VT52, the Elrog 300b and the EH 50. Since a pair of WE 300b's go for about the price of the component, I would like to try the WE VT52 and the EH 50 which Srajan said had an "hallucinate" sound stage. I want to know what that means. I like big sound stages. Vinnie's favorite tube is the Takatsuki 300b.
