EL 34s for Cayin A 50T Integrated Amp


I am thinking of changing out the stock tubes (The EL34s) in my Cayin tube amplifier, but don't know what brands to look for. I mainly play rock and I am looking to improve my base and possibly the level of detail as well. Does anybody have any suggestions?

Thanks for your help!

I saw a set of 4 Sveltlanas but they are not the "Winged C" that people are talking about. Are they good as well or is the difference night and day when compared to the "Winged C's? Also, the electro harmonix that you are referring to replaces the small tubes in the Cayin?
Olimpico,
Where can you get a quad of those ? Thinking about trying them on my Dialogue II.
You might also try the KT77 tube. It's a replacemnt for the EL34. They have better bass but not quite the romantic midrange of an EL34.

Audiogabby, I'm using Genalex KT66's in my Dialogue II to great effect. These tubes have great drive and amazing bass.
