Woo audio WA2 and beyer T1. I don,t have a problem with this setup, i like it, i just wanted to know what were the darkest tubes. I am ordering 7236 soon and then i wanna get really bottom heavy ones jsut to a the variety. The 5998's are great.

The tung sol 7236 seem to be really thick and warm but i dont think the bass is more than 5998. The RCA 6AS7G is quite bassy.

Try rolling ur 6922s, the reflector 6n23p-ev are bass monsters. Combined with the rca tube, the amp becomes a little muddy sounding, but the T1s will sound like Dt 990s with the bass sometimes, tons of bass

To me with 339 amp, 7236 has little more gain than 6AS7G but it's not bassy. It's actually more dynamic and transparent. 6AS7G is darker and thicker. It's slight though. Same with Bendix 6080 slotted graphite plate, compared to 7236 it's dynamic and lively with strong bass, less bloom downlow than 6AS7G but more control.

nice, thanks for posting this. this is what i want to try next. have you used this combo with hd800?

I agree with telecaster - in cathode follower otl amps, my experience has been that traditional 6as7(g)/6080's are slightly darker and bassier as they have higher output impedance.  Higher transconductance, lower output impedance tubes (i.e. 5998's and 7236's) have higher gain and sound a little faster, livelier and brighter in my setup - although still have plenty of good deep bass for my tastes.

 

Note that this is also going to depend on your specific headphones.  E.g., the HD800's have a mid-bass impedance spike on their curve so their FR really does change based on output impedance.  Phones with a flat impedance curve should not be impacted as much in this regard.

not really, i find that the bassiier tubes take away from the transparency and detail, though they are quite fun to have!

 

by the the definite/best combination i've heard for the HD 800 is the  Tung Sol 5998 or GEC 6AS7G with Amperex 6DJ8 Bugle Boy's and RFT EZ 80s.

 

the stock rectifier or maybe the mullards might have more bass, but the RFT is by far one of the best, well balanced and great extension and clarity.

 

you would be ok with the sylvania 7308 and 5998 for the hd 800, the 7308's already have very good bass and the 5998 has a little weight in the bass as well. the 7308s also have great extension in the bass as well, the 6N23P-EV are similar sounding, but slightly more treble and bass, the treble smoothens out alot with burn in, great tonality.

 

the bugle boy's are smooth, warm, with great soundstage, bass is well balanced and full but not super strong, they are incredibly good tubes.

 

and the 5998 as i said i find to have a bit more bass than GEC 6AS7G as well as being warmer. the GEC 6AS7G are slightly brighter, mostly cause they're very analytical, but they have a great synergy with the HD 800, the best tonality out of almost any of the other tubes, transparency is a league above 5998, and the sound basically has no flaws, thats the first thing i noticed about the tube, usually they all have some flaw, but this one really has no problems at all and performs at top level in every category. the soundstage is incredible as well as the imaging, really works well with HD 800.

 

 

only thing i'm missing now is siemens CCa or some ultra rare amperex tube. i can't imagine the WA2 sounding any better though.

You should also try the bendix wb6080 with graphite solid/slotted colums.. I liked them more then the 5998 in the end when they were burned in...but they are almost not to be found anymore i understand.. Takes a long time to warm up to working temp also in my experience..at least 30min.

yes they are..as i said..i had a pair of both of them...paired with ts or rca as drivers..and i liked them more then the 5998's..sound got more open..and faster...more 3d..less surrupy... In my 337 i had anyway... I loved the bendix best with the rca redhots 5693 as drivers... Especially With live recordings in high quality lossless material this pair sounded by far better then my 5998 with sj7gt mesh plates as drivers... But as one smart guy said... Every tube amp reacts different on tubes.. So maybe fr a woo audio amp the 5998 sound better..dont know..u just have to try out i guess... But those bendix are hard to find..so if u find a NOS matched pair..jump on it! biggrin.gif

UPDATE..i have my 'evil one' back for a few months to use...until i have my new amp that is....i can use it while my friend is out of the country for business for a few months....i have such good friends!!! tongue.gif

but OMG...he sounds soooooo F..Cking good... i even called my boss last night and took 4 days off...so until next wednesday..all relaxing!!

compared to my not really cheapish onkyo speakeramp (which sounds wonderfull by the way on my tannoy speakers) that i used since i sold my amp its a HUGE step in sound quality,,,

no matter what u speakerguys say...for me the 337 is the best amp i ever heard for the he500..PERIOD!!..especially with the bendix and rca redhots 5693's....okay i mean this evil (modified) 337..somebody did some magic on it...am glad it has a good home now..but damn its squeeky clean..and no dust..WTF did they do? put it in a dustfree/oxigen free case or something?...redface.gif

I am very happy with the sound I am getting out of the 5998s and mesh plates/5693s. But my curiosity always gets the best of me and I wanna try new things. So now I have more tubes on order. There's also the novelty factor of collecting these rare tubes.

Ive always been really curious of 337/339 and he-500 combo, seems like it would be similar to t1/wa2 combo, not much talk about he-500 synergy much less he-6. I know the best amp ive heard he-500 on is the allnic hpa-5000. But thats a $5500 amp

Yes ur right..there is almost no talk bout the synergy with the 337/339 and the he500----the 339/337 owners are not of the bragging kind (check their 339 thread and mention if the 339 goes well with the he500...and then see what happens..lolz..

in general they just enjoy listening to it instead of talking bout it elsewhere on threads..just like blue circle audio owners..silent lovers... They dont need to prove that they have something special...

But another thing... the 337 i had was heavily modified under the hood by the first owner...i bought mine second hand...so i guess because of that it sounds so heavenly also

Just try a 339/337 once with ur he500

Ps..i tried the he6 with my amp....horrible! Lack of power!!! Bad Also with the hd800 ( the previous owner sold it to me because he just had bought a hd800..and hated the pairing)..bad!

.lcd 2/3 ..was okay..not great.

But hd650/600, beyerdynamic mmx300, he500/400/300... Good pairing! (Owned/tried them all!)

Best pair until now was the hd650...u wont believe what u hear from the good old hd650! On second place the he500..well u know how i think about that pairing..and then the rest i tried.

hmm, i am also looking at amp upgrades atm.

 

right now though im very happy with how hd 800 sound with WA2 and the GEC 6AS7G tubes, the transparency and clarity even rivals that of the LCD-3. so natural sounding and zero grain with this tube.
