post #7921 of 29797

Thanks for your insights. I have a USB DAC, so I chose a Firewire HDD. Last week, I added a 5v linear power supply to my DAC (EMU-0404) and the difference was huge - my Woo certainly liked the extra attention. This now has me thinking is there any gains to be had if I replace the switching adapter on the HDD with a linear supply? Or moot in the same way the quality of the USB/Firewire cable wouldn't matter?

Since the Duet is FW, I have the OWC Al-Pro mini on USB. I will move it to FW when I get the Wyred4Sound which is USB (or Toslink).

Did you add the RAM & SSD one at a time or at once? How would you determine each of their improvements individually from stock? Small, moderate or huge gain?

Thanks.

I put my WA2 order in on January 6th, 2011 and got the shipping notice yesterday (January 17th)....so I guess you should be getting the shipping notice later this week/early next week.

I bought the EML from Jack.  He felt very bad that I was having issues.  He replaced each time under warranty so it just cost me to ship the defective tube back to him.  The last time I told him to wait until he got 1 of the new batch so I was without an EML for about 2 months while waiting.  I'm glad I waited as the new EML is working like a charm.  Also glad I bought through him.

The EML is around three months old, so it's not very old.  I am sure Jack is busy, so hopefully he'll get to me soon.

 

Thing is, I have not seen any posts here about EML's dieing in WA22's.  What have you heard?  Does the Transporter use the EML 5U4G?

 

Thanks.

 


 


 


I don't know what style I have.  How do I tell?  Did you get your EML from Jack?  He has not answered my email yet, but I am sure he must have a stack of other emails to answer first.

You might need a bigger power regenerator if you move into the airstream!

Thanks for sharing your experience, it helps.  Hopefully I will hear back from him tomorrow.

The new redesigned EML5U4G mesh plate will have a silver top.

The older EML5U4G mesh plate have been out of inventory for about 7 months.

 

Anyway the new and the old EML5U4G mesh plates are about the same sounding tube. If I had to choose between the new and old I would take the new version.

I hope so I am really excited about this purchase. It's my first headphone amp so I do not really know what to except. Always been a 2ch Loudspeaker guy before I found this site. Sort of wondering if a headphone amp can be compared to the same improvements that a dedicated phono stage/pre amp offers for SQ on a turntable, wherein soundstage and overall control are much better as well as the obvious volume gain. If this is the case I will certainly be happy with it. @MacedonianHero Did you go with the stock WA2 or did you opt for the Blackgate caps or other upgrades?

sillysally didn't last set of EML you had have clear tops?

I thought that was one of the differences in the redesign?

Thanks

Dropping in on the conversation... 

 

20101228-094005-IMG_0045.jpg

 

 

Just got a WA22 and want to share some initial impressions for anyone else looking to pair them with D7000. Now I wish I had joined you guys years ago. I normally don't give initial fanboy honeymoon impressions, but couldn't help it this time.


FLACs, 192/44 mp3s(so sue me) -> DacMagic -> cheap XLR cables -> Woo Audio WA22 (stock tubes!) -> 4pin XLR + stock cable (not in pic) -> D7000 (markl, j$)

Initial impressions:
This thing is AWESOME!  Pure sweetness with wide and airy soundstage.  Clarity, power, deep bass, you got it.  WA22 is laid back yet forward somehow.  It's very musical and easy to listen to.  No fatigue at all.

 

Head-fi Chesky tracks since most have these:

  • Tumbao De Tamborito -  4:00-6:00 sequence is airy and easy to locate individual drums.
  • Heartbeat - 1 scary, 2 scary, 3 good bass, 4 dropping off (could just be my hearing)
  • Money - clear instrument separation and drummer on the right has excellent imaging.
  • Get Behind the Mule - around 3:30, the reverb on the tapping is incredible.  One of those, "I never realized it moments."
  • Texas Rangers - sweet voice.  The airy soundstage makes her voice less in-your-face and pulls her back a bit.  She's still clear as wire, but more "speaker-like."


Balanced vs Single Ended?
My non-golden ears can't tell, only that it sounds damn good. Switching between the balanced/SE inputs (4pin XLR and 1/4"adapter plug) on the WA22 is a very noticeable improvement.  However, it's could be the push pull topology is just better with balanced input (or the level boost).

Previous experience (all from super duper accurate memory):

  • Owned: SACD -> 61NP diy amp/Little Dot MKIV -> hd580/600/650 (good for acoustic guitar)  Compared to current: not as airy
  • Owned: SACD -> KGSS -> Omega 2 (awesome, in a different way. un-listenable with with bad recordings. not a fan of it for rock)
    Compared to current: requires good recordings, just different character.
  • Owned: SACD -> cheap speaker amp -> K1000 (It's the K1K, how can it not be awesome) Compared to current: less bass, but
    K1K is just special.
  • Listened: SDS->L3000/R10 Compared to current: both are lovely, can't say I remembered as much "air" but it's been too long.
  • Listened: SACD -> McIntosh -> Apogee speakers (killer soundstage/imaging) Compared to current: headphones have better clarity
  • Listened: SACD -> ML monoblocks -> Genesis 1.1 speakers (No headphone, dynamic/e-stat/planar speaker I've ever heard comes close to this thing's clarity, attack, imaging, and impact) Compared to current: 1 ton vs 30lbs.  delivered by 18 wheeler vs your friendly fedex guy.

 

Edit: note with balanced inputs, my normal listening level is 9 o'clock on the volume knob (not like the pic).  plenty of headroom.

Nice WA22 impressions (and a nice WA22 as well), hozo.

My EML 5U4G is only a few weeks old and it has a silver top, I hope it lasts for awhile!

Yes first redesigned had the clear top about 11 months ago and I think EML switched back to the silver tops about 7 months ago for there redesigned EML 5U4G..

Anyway the EML 5U4G's that both Jack and George are shipping are silver tops.

 

I have both redesigned clear and silver top EML 5U4G mesh plates, for my system I can't tell any difference between them. As I said there was a little difference between the before redesigned and the redesigned.

 

Yes I understand what you are getting at but at this time I think it to be ill advised to start a witch hunt. That said you may want to keep track of the clear and silver tops that go bad, but I don't think there is any problem as long as you let your amp cool down before you restart it. wink_face.gif

Thanks sillysally, I was only trying to confirm the different versions of this tube.

I'm sure, as you said there is little or no sonic difference between them.
