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

@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!

yeah, i hope this Telefunken video will make you laugh :)
you know what to do now
@chakster  Interesting commercial! I'd like to see an updated version by Seth MacFarlane!
Thank you for the kind words.  The price of Brimar tubes has generally been lower than the Mullard equivalent. To be perfectly honest I haven't bought a  Brimar Trustee  6060 in many years.  I would guess that because of their scarcity that  it will boil down to you and the seller agreeing to a price usually on Ebay.  I think that $100-$150 range people have mentioned seems appropriate.  I still have 2 or 3 of them.  Which brings me to the other point people have been alluding to.  Tube rolling is indeed a slippery slope.  I too couldn't get over the fact that with most tube rolls I heard a different sound.  I liked it so much that I have a stupid number of tubes.  I suppose I should sell but then I would want to buy them back again. 
Not only did I like rolling the various tubes I was using, I then just collected them for any of a number of reasons.  I also thought I should get back ups for them.  You see how it goes-
So you can stop now or forever hold your piece.  Quite honestly I enjoy my tube collection. However,  I am still wondering why I bought so many short bottle 6SN7Ws. I have about 16 of them.
I hate selling, many of these tubes are 70+ years old and might not sound great or even good in the buyers gear.  I don't want to deal with complaints and returns, I am not a department store.  At the same time I don't like it when the seller says no returns whatsoever, or as is. as found.  I  have been burned many times by unscrupulous sellers and have bought some real loser tubes .  One prominent example is my experience buying Western Electric 421As. I was buying them for a headphone amp I bought that uses 6AS7Gs and 6080 power tubes.  So many were feeble shadows of themselves, and I got the sense that the guy was selling it was simply trying to get his money back from the last guy.  I swallowed a few and decided to look for other brands of the same construction, e.g. domino plates. I refused to do the same passing on a weak tube.  That's what honesty buys you.
