The best tube I've tried so far has been the JJ E88CC's. these are dead quiet, even handed and have a vibrant sound, underpinned by a solid bass register.
From Germany I've use Tube Town as a supplier in the past over UK (my location) suppliers.http://www.tubetown.de/ttstore/produ...Red-Label.html
Thanks for the recommodation!
Funny enough, I was in contact with tubetown.de since yesterday, asking them for advice.
They recommended the NOS "Philips JAN 6922 Audio", allthough being "critical", and the JJ that you just mentioned.
I asked them what would be "critical" about the Philips, and they replied:
"Stability. We often see disorders, or they tend to Microphony after a short time. But once you get past the first 24 hours, you`ll have a very nice and detailled tube".
I was like: WTF?? What kind of reply is that?
Not exactly a recommodation, now is it?
I was such astonished by the honesty of that reply, that I spontaneously ordered a pair of them!
At the same time I`ve read you recommending the JJs too, so while I was at it, I simply decided to try a pair of them as well. They aren`t exactly expensive anyway, and should the Philips fail, they might be a nice substitute.
Well, sometimes such decisions are made under weird circumstances.
Did you try the Philips with your rp5.1 as well?
I`ve ordered the 5.1 as well, for the AD2000, can`t wait to get it, hopefully next week.
What were the stock tubes in the rp5.1?
And are the Amperex worth their price, where did you get them from?
I`ll certainly first try the stock tubes in the amp, and plan to change the tubes only if I dislike something.
Like it was the case with the chinese tubes in my CD-Player!
Thanks to everybody who gave advice, it`s very interesting, and I`ve learned a lot!
