Very tempted on the TH-900s...How are they compared to D7Ks, worth it?  I've read a lot of opinions and the general concensus seems to be that they're an improvement but are not worth the money.

 

LCD-2/3's look nice...will go to a local meet soon and Audeze will be there.  Sure to check them out!      

 

I have never heard HD800, but used to own Beyerdynamic T1 and your reasoning applies there too. However, there is something about Denon AH-D7000 that I truly love. It just takes some time for the brain to adjust from other headphones (like LCD-2r1 and LCD-3) when going back to them. For example, I like to use Woo Audio WA2 with 6AS7G tubes with D7k. This is really not ideal, as WA2 is an OTL design and not recommended for very efficient headphones like the D7000. The sound is far from neutral, in fact it is really colored, but I absolutely love it. :D The combo sounds big, bold and beautiful, haha.

 

Actually, I don't think D7000 and TH900 have much in common besides the form factor. I've written about it in the Fostex TH-900 thread, but most people do not seem to agree with my opinions on that. It may be that I'm an Audeze kind of guy; loving that dark, yet detailed and liquid sound. I'd get LCD-3 before TH-900 every day. I bought TH900 used without hearing it first, and if my opinion of them does not change, they will be sold again. D7000, on the other hand, is a stayer.

 

Be sure to try LCD-3/LCD-2 with Woo Audio WA22 or WA6-SE if possible. Also hear great things about Mjolnir and LCD-3.

i sold my denons a few months ago. they're great headphones but with the lawton mod i found them a little too sibilant on poor recordings for my tastes, i had to use 6EW7 and sophia to tame the highs, but then everything else sounded congested and smeared. also the denons lacked the resolution of the LCD-2 and the Beyer T1/HD 800. i'm planning to rebuy as TH-600 or TH-900 in the future though. the denons are awesome headphones and very fun! 

 

Agree with you on USAF-596 and GZ34 (the latter is also quite similar to GZ37). HE-500 is somewhere in my future, as ardilla here on the forums is going on and on about how great they are with AURALiC TAURUS (SS amp), which we both own.

 

6FD7's and 6GL7's I have not tried. Thank you for the input. The 6GL7's should deliver more power (and hence be suitable for the orthos), right? Which brands of those have you got, please?

 

Oh, I see. I have J$ Real Leather Pads, but quickly took them off as they made them sound far to bassy(!) and the highs were being far too much recessed(!). When I told the seller of the pads of this, he agreed and said that was why he sold them. Do you know if your Denons were old or new? Tyll @ Innerfidelity has talked about the sound quality being changed on the D[2|5|7]000 lineup during the passage of time. Mine are from one of the last production batches that were made.

 

Yes, I agree that they lack the resolution. It's actually pretty funny as I thought they had great resolution when I first got them, then I got Audeze, Beyer T1 and saw that they really didn't, haha. Beyerdynamic T1 is now sold, as they got a bit too sibilant for me. I know you like T1 a lot with WA2, so TH-900 may be something for you. They have great resolution, but the sound stage and holographic imaging is bested by T1 imo. T1 is brighter, but TH900 is not far behind. And the fun factor you get with that thumping mid bass in D7k is not found in TH-900. The bass goes deeper though, and it is more pronounced and detailed.

Yes they do have more power. Mine are GE brand 6GL7 and sylvania 6fd7. My denons where late 2011. The t1 is way different on wa2. Less bright and different sounding

D7k doesnr have good midbass, only subbass

Hi all!

I just scored a used WA6 with V-cap upgrade and PDPS, and I'm wondering if any of you have got any opinions on the tubes the seller included.

The classified said it came with stock tubes (though not specifying which, my impression has been that they're not the same for everyone), a Sylvana 5U4G rectifier (from the 40's/50's), a Golden Dragon rectifier (apparently with the widest soundstage and lots of bass) and a matched pair of GE fat bottles.

I've read through every post in this thread, and never found mention of the Golden Dragon. I saw some comments on the 5U4G, but from EML.

I'm also curious as to what tube the GE fat bottle actually is, does anyone have an idea?

I just closed the deal on the WA6, and it's currently in the mail (though I don't think it's left Canada yet frown.gif). It will be my first venture into tubes, and my first proper headphone amp.

I do like the D7000 sound with my DacMagic Plus, but I also find it a bit lacking (but can't really put my finger on it). Can't wait for the WA6 to arrive!

well the d7000 sounds great from wa6/wa6-SE! 

 

umm stock tubes generally are 6DE7 or 6EW7 power tubes and the really crappy Shuguang 274b rectifier.

looks like gold dragon is a new production tube, chinese.http://www.tube-shop.com/store/proddetail.asp?ProductID=63&RelatedID=&RelatedID2=149

 

the GE are probably fat bottle 6EW7 or 6FD7. the sylvania 5U4G is a good rectifier.

Thanks! Now I really can't wait biggrin.gif

Seems there are a lot of Golden Dragon rectifiers, both 5U4G and 274B that fit the WA6. Tube-shop was a good find.

If I want more rectifiers to play with, it seems I'll want a GZ34 (fat or metal base), a USAF-596 and the Sophia Princess 274B mesh. These seem to be getting the most praise here. If I can find one,

I think I'll start with the 596 as you found it to be the best sounding rectifier for D7000.

 

Though I think I'll settle in with the WA6 and the tubes that's coming with it before I start rolling more tubes. Though I am endlessly curious to try new sounds, and I've got constant uncureable upgradeitis tongue.gif

As such I think rolling tubes will be much cheaper than replacing amp, DAC or headphones, and should keep the upgradeitis in check for some time gs1000.gif

worked for me!

also both 596 and sophia can be picky with power tubes. the sophia is smooth and the 596 is more forward, so its definitely a good idea to get used to your tubes first and see which ones where actually included.

I actually didn't mind the 6DE7 stock tubes with the 596.

Question: Is it a fair assumption that similar tubes have similar sonic characteristics?

Will a metal base Philips Miniwatt GZ34 and a Golden Dragon GZ34 sound similar in the same way that the Denon AH-D2000 and D7000 sound similar?

If so, I'm tempted to get a GD GZ34 just to see if I like the characteristics with my D7k and drive tubes. They weren't exatly ruinously expensive...

post #549 of 1507

not necessarily. 

 

a shuguang 274B is nothing like a sophia princess and likewise, a cheap 5U4G is nothing like an EML 5U4G.

 

closest you will get is a black base GZ34. different tubes of the same type sound different.

 

sound signature might be similar, but you wouldn't be able to compare, the cheaper tube will be grainy, thin, and bright. the more expensive tube will be more refined and have a smoother more transparent presentation..

I just stumbled across this on Google, trying to find a 596:

http://www.worthpoint.com/worthopedia/lot-10-united-usaf-596-rectifier-150269263

 

That went to a happy buyer, I'd guess!

 

Too bad they were used...

Sold in 2011...before anyone knows about them.  I did some trolling and found some online stores (http://www.armyproperty.comhttp://www.parttarget.com) that offer them.  Wonder if anyone has looked into them yet?  It seems to be a lot of troubles to buy from these folks since they ask for a US business address (foreign export restriction?), wholesale quantity, and military association.  These seem to be pulled from equipment, not NOS.

Well, it took forever to get the RCA JAN CRC 5r4GY. After a few nights of listening I'd say Brent Jessee is right about this rectifier. It's very transparent like the sophia princess with more defined bass(but maybe not quite as extended). Images and layering are more well defined, but I think the stage might be a touch deeper with the princess. The only drive tubes i've used with it so far are canadian made 6de7 Westinghouse. We'll see how it does with the 6FD7's. This tube boogies better than the princess. I compared the 2 on a cd felt the sophia was a little slow? First impressions, but they are good. On the other hand I tried a gz32 a week ago and pulled it out after the first night. Grainy is not the right word, but not ...right.

Picked up my second hand WA6 today! Now my workstation smells of hot tubes biggrin.gif

Got noise from it on both channels with nothing playing and the volume all the way down. Turned out to come from my DAC, disconnecting the interconnects (or sometimes just touching them) made the WA6 dead quiet.

The USB portion of my DAC (Cambridge Audio DacMagic Plus) has a Ground/Lift switch, and setting it to Lift made the noise go away. Hot tip for anyone having similar issues.

 

Anyways, this thing is bigger than it looks! And I do love the build quality. It wasn't a monumental upgrade from the DacMagic (<5 min warm up, Denon AH-D7000), but it makes the DacMagic sound sterile and a bit boring. Can't wait to settle in with it, and roll some tubes. I popped in the Sylvania 5U4G to begin with, together with a pair of GE 6FD7 fat bottles.

The stock tubes turned out to be a chinese unbranded 274B (probably Shuguang) and Sylvania 6CY7s. The Golden Dragon is a 274B as well.

 

 

The WA6 looks very good, and matches my black DacMagic and black gloss desk very well:

The image quality on my Nokia Lumia 800 isn't that good...

sylvania 5u4g should be better than the other 2 rectifiers, and the 6FD7 are nicer than 6CY7

Well, it seems I've absorbed some of the tube rolling information you guys have provided then dt880smile.png
