Hi El Drifto and Rudy,

Welcome to the Audiocircle and the RWA forum - and thanks for posting!

I also have a pair of Telefunken's E88CCs that I enjoy.  Never heard them Cryo'd yet.
Soon enough I need to post some tube rolling updates here, as it has been a while.

Thanks for keeping us posted!

Vinnie

This thread was confusing me since the Liliana RE and the Isabella RE can both take some types of tubes but cannot share other types of tubes.

I made the diagram below as an unconfuserator. I believe it's correct?

Regarding the stock JJ tubes in the Liliana RE, I find a variety of types available. Eurotubes has a comprehensive list: https://www.eurotubes.com/cart/index.php?page=view_submenu&category_id=2

Which of these 12AX7 variants of new JJs is stock with the Liliana RE?

ECC83S ( 12AX7 )          --the standard one seen in most online stores
ECC83S Gold Pin            --the gold pin version of the above with perhaps some additional quality control at the factory (?)
ECC83MG                      --a mid-length, ribbed plate version with lower gain than the standard version (#1 on this list)
ECC803S ( 12AX7 )        --a long-plate version
ECC803S Gold Pin          --a gold pin version of the long-plate version

Hi newzooreview,

Looks good, but there have been times when I've shipped the Lilianas with JJ E88CC, and other times with JJ ECC83 (because I was out of one).  In the case of these two JJ tubes in the Liliana circuit, they sound very similar.

Hello All,

I'm using the Red Wine Corvina in balanced mode with LCD2s (stock cable)

Using the stock tube but would like a little more definition in the high frequencies and a bit more air and space.

Reading this thread it seems the Miniwatt Dario 7308/E188CC or Amperex 6922 Pinched Waist are highly recommended and have a more open, airy treble than the stock JJ..

I listen to all kinds of music from acoustic folk and jazz through to Hendrix and Stones, Nirvana.

i generally like a rich textured sound but also want to make sure the sound doesn't become too cloying, over-polite or congested.

Can anyone advise me if the above two tubes would be best for me or are there other alternatives?

Thanks,
Ken

Hi Ken,

Welcome to Audiocircle and the RWA forum!

I would recommend first upgrading the stock cable, as it does lack in high frequency extension.  While not cheap, this one
would be on the top of my list for the LCD-2s:

http://www.aloaudio.com/cables/headphone-cables/reference-8/reference-8-headphone-cable

If you don't want to spend that much, tube rolling would be my next recommendation.

I've been playing with the Telefunken E88CC (that are being sold new-in-box from Upscale Audio) and they seem to have better
resolution, without losing the midrange magic. 

But what what you are looking for, and for the price, the Mullard CV2492 is going to be hard to beat!  From first hand experience, I would get it from this guy:

http://www.ebay.com/itm/E88CC-CV2492-MULLARD-MILITARY-NOS-BOXED-/260577827114?pt=UK_Sound_Vision_Valves_Vacuum_Tubes&hash=item3caba6192a

I know, I know - lots of choices.  I don't think you'll go wrong with any of them, assuming the tubes are in good shape.

Keep us posted!

Many thanks Vinnie.

Unfortunately at the moment anyway I think the cable upgrade is out.

But I will definitely check out your recommendations about the tubes.

Thanks again. Will report back about any changes I make.

I have now had the Signature 16 amplifier for a few month and before writing a review , must quickly tell you about my tube rolling result...
Luckily , in my long crazy valve days , I accumulated a nice box of goodies...so , the dipping began ...as the Sig. 16 is a very neutral amplifier and my 99 db Horns crossover  at 900 Hz to a 12" , my thought was to get a bit more "valve flavor"  , so straight to Mullard and Brimar ....found the 12AX7 family to have better control than the 6DJ8's etc....
to cut a long story short...
the one outstanding with absolutely stunning bass control was the Siemens E81CC...triple mica...
Testing was done with Reference Recordings RR-S3 CD "Track 3 - Isaac Albeniz , Festival Day in Seville"...
enjoy...more to come soon... :)...
Helmut

Thanks for these latest tube impressions! I might be ready to experiment again......the stock tube has been awesome for me and my system. I like it's tonal balance, but if I could have more of that kind of flavoring then......hmmmm :)

I had some gold lion 6922's from cryoset that I liked at first and thought I preferred them to the stock JJ's......but after a while a put the JJ's back in and liked them more. I feel like I burned the GL's in long enough as well so that wasn't really a question :)

a "down under" update... :green:...

the previous tube which made me very happy was the Siemens E81CC/6201...
but , as usual after a while back to the famous tube box to see what else is in there...
the unusual sleeper I liked was a CV4024/12AT7WA which I believe was made by Mullard ,triple mica ,square getter...unusual configuration what attracted me here and yes , very nice...bass not as good as the Siemens , but... :D...a bargain...
and than a bit more digging and there was a couple of gold pin Siemens E188CC/7308 with CCA written on the glass...
whoopee !!!
Straight away , the Siemens balanced sound was there , with the Mullard midrange "richness" added...this one will stay in for a while...maybe more surprises later ???
