G9 with different tubes (soundfiles inside)

Some results from the Karlsruhe Hörsession:
Here´s a link to a packed 20MB file which contains several recordings with a G9. We changed the tube in the SRPP stage since there´s no feedback around this stage which could equalize nonlinearities.
The G9 was the OEP version. We recorded a padded signal from my HD recorder so that every tube after warming up the same time could get the exactly same signal through always the same channel.
Happy download and have fun

Some impressions from the action going on this day:

Test setup for comparing different preamps





Volker (silent:arts) dissecting an alphatone DI

Did not listen too hard, but the differences were very very subtle I think

I love these tests :green:

any chance to get an zip-file?
:sad:
I am not able to open this on my Windows PC.

Use winrar ( rarlabs.com )

Thanks! It works now!!!
Nice Testfile..... I can hear some little differences with my PC Speakers, but I would need to hear it back home again to find my favourit.

how the heck do I add a poll. It doesn´t work for me. Am I stupid??? :evil:

(no comments please)

..Edit your initial post, and at the bottom of the page there is an option named "add a poll"..

..dunno how it works, though..

Jakob, that´s what I tried. But obviously it´s not possible.

Was tun sprach Zeus?
:roll:

..maybe it's only possible at initial posting, not after replies has come in..

You may need to start another thread..

Everybody´s invited to tell us which tubes he liked best, anyway.

So let´s hear it :razz:

I did not listen to the files, but whatever file used the tubes in your avatar, thats the file I like the best!

Gustav

can´t exactly tell which I like the most... I´m in the workshop...
to me the 02-valvo sounded a little different than the others. seems like
the esses are more kinda sharp in this recording.

I tried to have an analytical listen, and although it was all very subtle, I was able to pick favourites.

Siemens und Halske ECC82 came out as the best sound. It really performs cleanest and has the "high end" edge over the rest of these. Secord favourite was GE ECC82. Is it just me or does it sound a bit louder than the rest of these? It could be the distortion it produces that gives that impression, and the impact seems very usable.

Valvo struggles with sibilance and high frequency definition, and sounds almost broken in comparison to the Siemens.

The rest of the tubes sound quite OK, but I always went back to the Siemens as reference, as it sounds that much better than the rest.

Playing Valvo and Siemens side by side, for example, the difference isn't all that subtle anymore.

"Darmsanierung" doesn't sound very good in general :green:
Other than that I would use any darm.. err... tube you'd tested.

:wink: Frank.

You know, I'd love to say these comparisons were useful, but regardless of which tube is used, I still can't understand a damn word!!!

:razz: :razz: :razz: :wink:

I bet you don´t want to know anything about Darmsanierung.
:wink:

Hiya Chaps,

Filled my G9's with NOS yellow badge Mullard ECC82's - Best so far .Even on blind testing

tried GE, tfunken, trigor, tesla's - more 'sound '( can't explain it - just richer, fuller better sounding), with the mullards', and that's not just my opinion :wink:

wish I had more

Steve :thumb:

i've just listened to the clips and notice they are all incredibly hissy. i was thinking of doing a g9, but not sure if they all sound like this. :shock: do they?

thanks. :guinness:

I have ordered a few Philips 5751 tubes to compare.
