The C3G destroys them. Not even close. The extra detail, dynamics, extension, clarity is a step change. My audio buddy puts it around 20% vs the TS RP in my WA5 with Takatsuki 300Bs/274Bs. I'm thinking more around 10-15%, but either way, those are huge numbers given that we are already at the pointy end of audio diminishing returns.

 

The only thing the C3G doesn't do is add any warmth to the music - it is ultra transparent and neutral. In every other department that I can think of, it smashes anything else I have heard. Personally (and a big, fat YMMV applies here) I would not consider any other drive tube.

Tony, how do you compare the Tak 300b to other 300b tubes?  I have not heard a 300b in a very long long time.  Maybe last I heard one was like 13 years ago with a Rethm speaker and then it sounded glorious.

I am not the best person to ask as my 300B collection is quite limited (compared some others). Best alternate tube I have is the SERP. That's a good tube with good extension, but the Taks are better IMHO.

 

There are folks out there that have heard the full gamut of vintage WE300B, reissue WE300B, Taks and others. They tell me that the Taks win. Similar midrange magic as the WEs, but combined with better extension.

It is my understanding that the 6SN7 isn't really up to the job of driving a 300B. And if my understanding is correct, it is not at all surprising that a C3g destroys them in your amp.... 

 

For a different perspective, I have a 6AS7-based Glenn OTL designed to use either an SN7 (or similar double triode) or a pair of C3g. In this amp, neither the Lorenz or Siemens C3g have gotten much use recently. Primarily, this is because I am a "tone" guy. If vocals and instruments don't sound correct, then no amount of detail and resolution can compensate. And at least to my ears, the C3g just doesn't cut it. Further, there are a number of other tubes, such as the E88CC, and especially the E80CC, that can rival the C3g in resolution and in fact, are even more linear and have less distortion. Thus I have many, many high quality tubes to choose from. Until recently, the Sylvania 6SN7W occupied the driver socket most of the time. And at this time, an ECC31 is my go-to tube. The tone is correct and to my ears, I do not find it lacking in resolution.

 

Don't get me wrong. The C3g is a wonderful addition to the Glenn OTL. But to my ears, it is but one of many equal, but different choices.

 

Cheers

The C3Gs in my WA5 do have a slightly elevated tone in my WA5. For my preferences that is a small price to pay for the glorious SQ these tubes deliver. The E80CC... etc are tubes I have never used (but they have my attention).

Thats what I also heard when lurking in other forums.  The Tak is a very good tube.   

 

About the C3g and other driver tubes, I guess it all depends on the circuit of the amp.  Using a pair of 50's RCA 6sn7 with support rods, it sounds wonderful in my Liquid Glass but not so good in my Glenn OTL.  Then some NU 6f8g sounds noisy in the LG but sounds great in the OTL.  Weird right?

Tried the 50s RCA - didn't do it for me. I have had a number of noisy NUs - seems to be around 30% of mine (6F8G). Not weird at all.
