EL34 & 6L6 characteristics

I finally got my garage sale tubes tested out , thanks bigshutterbug !
I rolled in some EH 6L6's in place of my EH EL34's to compare . About as close to apples-to-apples as I can get .

I am asking if there is a tube that combines the characteristics of these two tubes ?
I like the warmth , body and bass of the EL34's and the top end , detail and air of the 6L6's . Is there something that would have all of these characteristics in one tube ?
Yes , I want it all !

Thank you

I find 845 tubes to have the midrange magic of 300b but they have great bass with slam

Yes Almarg , you are correct . I am looking for one tube that will combine the characteristics of both the EL34 & 6L6 . I want this tube to be able to be used in my current amp , a Primaluna Prologue II .

Analogluvr ;
Yes these 6L6's do have bass but not as much as EL34's and the 6L6's are nowhere near as warm as EL34's . The warmth is the most important thing that I want to add to the 6L6 characteristics .

Thanks to all for the response , please keep it coming .

I have no specific suggestions, but for everyone's info the Primaluna Prologue II is apparently supplied with KT-88's, with the manual indicating that 6550's and KT-90's can be substituted, and that "you may also use EL-34, 6L6GC, 7581A and KT66 though power will drop slightly."

Saki,
I used the Shuguang Black Treasure 6CA7 in my Primaluna Dialogue One. It sounds to me to combine the best attributes of my NOS Reflector 6n3ce (6L6) and my NOS RFT Siemens EL34. Better detail and air, yet full, a drop of warmth, increase of quality bass. Generally all around better in my system. The Simens are also good performers. You might also like the Bugle Boy 12au7s in combo with Sylvania 5751 3 Mica Black Plates in the Primaluna. I know I like them a lot.

Mikirob ;
I have rolled the small tubes to Mullards for the ax's and radiotechnique for the au's and they made the biggest difference for me . I have lived with the EH EL34's for quite a while .
How plentiful are those Shuguangs and Siemans 6CA7's ?

Thanks
