Tube recommendations


Hi all
The phono stage within my pre currently uses these 3 stock tubes - Sovtek ECC83, Electro Harmonix ECC81 & ECC88 (I think it's Tung Sol).
As I'm new to tubes which tubes would you recommend to be a significant  upgrade?

Thanks 
Rich

@lowrider57  Thanks for the info. From what people have said & from the tube characteristics outlined on Andy's site I think I'll go for the Telefunken tubes.


@chakster  Yes I can see how it would be addictive - I like to tweak so the addition of tubes is a blessing & a curse!

@chakster  Interesting commercial! I'd like to see an updated version by Seth MacFarlane!
