The Elrog rec was dwarfing the KR 2a3 tubes. swapped in the EML 300b 2.5v tubes and suddenly the Elrog doesn't seem all that big a tube anymore.
The 2022 Utopia and Cardas Clear cable + WA33 and this tube combo sound sublime. i believe it is well run-in, and the Elrog is now being used more often than my Tak274b rec. very much enjoying the clarity, space and air the Elrog 5u4g rec brings to the table. it evens out the sound of the 300b 2.5v tubes.
Really love how the amp looks in the lounge. always a conversation starter when non-audio friends drop by the house. "why are there so many light bulbs on your stereo system?"
