If i remember correct a member here compared the gz37 "fat glass" type rectifier with some other good rectifier tubes, but i cannot find the thread now.

 

It is realy nice to hear about other member's views and experiences around the many different tubes out there, it realy makes the choice easierregular_smile%20.gif

 

Don't shoot me for this, ok... I bought an used Mullard GZ37/CV378 (brown base).  In my opinion, it sounds not as good as the Sophia and 596 on the WA6SE.  The bass extension is lacking.  The mids and highs sound a little weak compared to the Sophia/596.  Overall, it sounds a little shallow.  It may be that my particular tube is a lemon (I've had different experiences between same brand tubes before).

 

Wish I can try a GZ34 one day.  I personally like the Sophia a lot (I currently used it over the 596)

Saw several metal based GZ34s on eBay...very tempted.

 

But need to stop getting tubes for the wa6se.  Got to save the pennies for a new amp.

im interested in trying out one of those U52's i was looking at the other day.

 

gotta save money here too though, wanna buy a car soon, and a new DAC, as well as replacing my TV which is only about a year and a half old.

I'm a new owner of a Woo audio 6 SE amp. Thanks a lot for all the people in this thread/forum who have provided a lot of valuable information on this amp and made me aware of Woo Audio in the first place.

 

I'm using a Audiolab M-DAC as a source (and also a Rega Apollo cd player) and my headhones are my good old HD-600 (with upgraded cabling). I received a pair of RCA 6EW7 driver tubes with the amp. I will post some images later of my set-up. I'm pretty new to headfi. The last decade I have mostly ventured into regular hif. But I realized I was rarely able to really play it on reasonable living in an appartment and  mostly listen late at night. It was painful especially to part with my beautiful Pathos Logos hybrid amp but it was a waste not to use it.

 

I bought the Sophia 274B/n rectifier right away with the WA 6E amp. As expected based on the posts here I found this to be a big upgrade. I do however not yet get the sound that I had when I tried out the amp beforehand. The sound is too bright (I have been burning in for a while now) and lacks bass impact compared to the trial. I think the RCA 6EW7 driver tubes are the culprit. My reference point for comparing the sound of the WASE and its configuration is always the built-in amp in the M-DAC.

 

At the moment I'm trying out the Syvania 6GL7 which I borrowed. Unfortunately I more or less get a confirmation of what I read in this thread.The spaciousness of the music is gone and my headphones sound boomy just like my hi-fi set started to sound in a small room with the bass bouncing of the wall. The good news is that I learned that also the drivertubes can make a huge difference in the sound and bass since at the moment my configuration with the RCA 6EW7 has zero slam. I'm looking for a sound that has a nice dark undertone and an adds smoothness over the seeminly bright 6EW7's I have now. Should I look into the 6EFD driver tubes? I have read a lot postive things about in this thread and its synergy with the Sophia. What should I pay attention to in getting a pair? Any help would be very appreciated.

 

The kind of music I listen to mostly: Radiohead, R.E.M., Neil Young, the XX, Depeche mode, Elliott Smith, Fleet foxes, Damien Rice, Bjork, Atoms for peace, the National, M83, Nick Cave, James Blake, Grizzly Bear etc.

Welcome to head-fi and i'm sorry for your wallet.

I'm currently enjoying some RCA 6SN7 which are providing some very enjoyable sounds compared the 6EW7 I have which I find are very bright. I'm also new the tube amps and what I'm learning is many tubes have so many subtle differences that you just have to keep trying different ones. What I'm also finding is that some cheap tubes on eBay can sound extremely good!

Good luck!
post #667 of 1391

Thanks a lot. The 6SN7 only are for the 6 version right? It's a nice hobby to have. With my photography equipment I more or less go through the same process picking the perfect lensbiggrin.gif.

 

Unfortunately I have to justify my spending these days since I got married a few months ago. Which means the LCD-2 headphones I have on trial now have to go back. Getting away with tube purchases is easier unless it gets out of hand and they stack up. I will try do look around on Eba yas you said and I also asked some local hi-fi stores whether they deliver tubes different from the standard ones they list.

Thank you! i will take a look in that thread.

Thanks a lot for your feedback Sko0byDoo!

 

"I personally like the Sophia a lot ( I currently used it over the 596)" Really..? thats interesting!

 

(From Mullardtubes webpage)

"Mullard GZ-37 / GZ37 / CV378"

"An absolute favorite with Audio Note & Kondo amplifier owners.
Highly versatile & adaptable. Without a doubt the finest GZ-37 available today only exceeded by the High Wycombe CV378 "Fat Glass"

 

About the bass "tigtness"/extension and soundstage, the "fat glasss" version should be on the + side according to many reviews, but then again very hard to compare between different AMP's.

 

 I think ill stick to a good Mullard/Amperex GZ34 Black base and save some Money, i read many positive experiences about this tube here..regular_smile%20.gif

Correct me if I am wrong fellow Woo'ers, should he expect bass slam from the HD600?  I have tweaked my setup in every way possible and I am barley getting that slam with the HD650's.

 

Also, congrats on the purchase!  I am also new here, only a couple months and have already spent sooo much money on tubes etc.  My favorite combo is the 596 or Sophia with the Sophia 6SN7.  So clean and punchy!

6SN7 only works on WA6, need a custom adapter for WA6-SE

 

i agree, the 6EW7 is a bass light tube, smooth but can be a little harsh for some people, my 6ew7 where personally ok, and i enjoyed their sound, but alot of people don't. also the sophia will get smoother over time.

 

the 6GL7 is good with a few tubes, with the sophia its a muddy mess. 

 

i would recommend 6FD7 or 6DE7. the 6FD7 are better balanced, the 6DE7 are smooth and tubey but can be bass light as well.

post #672 of 1391

Thanks a lot teknikk. Perhaps depth or amount is the better word. At the moment with the stock tubes there is none.

 

I'm starting to fear for my wallet already. One day I will look at different headphones. It's more fun to go step by step I find.

Thanks a lot for these insights.

 

I will try to pick up a few pairs of 6FD7 and 6DE7 to start with. Is there a big difference in brands here? Which one should I get that is both "tubey" and has bass impact?

 

I will pass on the 6GL7 now. Perhaps I will come back later on it once I have different rectifiers. One of my local hifi-shops has the Mullard GZ37 and 33. In terms of driver tubes they only have the more "standard" ones (ECC88, 12AU7, 6SN7) . It's a good thing I don't have to get those. These really burn a hole in your wallet.

post #674 of 1391

im not sure theres a huge difference in brands. i try to go for sylvania or GE., theres also RCA which generally are tubier though im not sure how it works with these tubes, also i think tung sol made some of these tubes, but they're pretty uncommon. 

 

and lol yeah, ECC88 and 6SN7 can be pretty expensive.

Thanks a lot again. I'm going after the tubes you advised me now!

 

Those ECC88's were the ones I had on my Pathos hybrid amp before. A few year's back they were much cheaper though. I should have just bought them all upbiggrin.gif. Pathos have come up with a hybrid headphone amp but so far I have not read any reviews on it.

 

The 6GL7's I have on trial this weekend sound amazing with voices. I was just playing the National's latest album and the deep voice of the singer just sounds so real life. The 6GL7's do introduce noise. In my setting only really audible with the volume beyond 10-12 o'clock. With these tubes I nowhere get near that point though. I will but them at a later stage once I have more rectifiers. Even my wife who I played some Amy Winehouse to thought the combination sounded shut in. Everything coming from one direction.
