Ghere are tons of speaekrs that this will drive including some great floor-standers like Coincident Technology,ZU,Tektron and Omega just to scratch the surface then there sis Salk,Hawthorne and many more. The sound for me of the direct heated triodes make this end game for me.

thanks frank. this is the no1 one amp for me now. i probably wont get the money together for a while because i have decided not to sell the WA2 and i will get a DAC first - maybe B stock vioelectric V800 from thomann. Of course if i sell some paintings you never know what could happen.wink.gif

That look like an LE not the WA5. The 5 has the speaker post and the XLR output

Does anyone have advice how a WA2 would drive some JH Audio JH5 Pro's?  Jack recommends the WA2 to drive headphones between 25 and 600 Ohms.  The JH5 Pro's have an impedance of 21 Ohms.  Safe to be driven by the WA2?  Or, should I look into buying an extension cable (which I need anyways) with an inline resistor?

i don't know if the WA2 is up to the task. Anything below 60 ohms is usually a no go.. it says 25-600 on the site but 32 and 50 ohm headphones don't sound good on it, at least the ones i have tried. some stay above 150 ohms with the WA2 for saffety. 

 

I would be sceptical of those impedance leads some people think they are a gimmick.

I'd really want to hear them on the WA2 and figured at the least an extension with a resistor would be ok.  Is that not true?

post #26256 of 30983

Mmm yes, this talk about wa5 is relevant to my interests...

 

My only concerns are that I'll need to buy another 5u4g to pair up with my left over eml, and to get an 3xlr to 4 or se connector for the T1.9

Waiting and dreaming about a new Woo is the best part!beerchug.gif

It's up and running...  Dueling 596's are quite impressive in the WA5LE.

 

Initial impressions: more slam than the EML 5U4G.  Dynamics are what the 596 seems to be about on first listen. 

 

They seem more aggressive to me.

double mighty 596s!!!!!

 

yeah, they're great tubes. best rectifier in my WA6-SE, very forward, dynamic, and clean sounding. very transparent.

sweet jesus they are nice - you must post more pics with different angles.

Resistance adapters don't do much for the headphones.  All they do is change the impedance that the amp "sees," and not the impedance that goes through the headphones.  In OTL amps, such as the WA2, the output impedance is actually determined by the interaction of the output tubes and the headphones they're driving.  By adding a resistance adapter, all you're doing is raising the output impedance of the amp, which will likely make it sound worse.

 

Now, when it comes to amps, headphones, and output impedances, you can basically run anything you want.  You're not going to damage your headphones and you won't cause the amp to blow up.  Things just may not sound as good as they can.  Considering many stereo receivers have output impedances of 120 or 470 ohms, and they don't blow up when using headphones, there's really not much to worry about.

 

But, I'd still ask Jack if his circuit design can take the low impedance of 21 ohms.  I don't see any reason why it physically cannot take it.

it will take it but will also sound bad IMO

Beautiful shot reeltime! The 596 is my favorite rectifier....

I'm a 596 man but I still lurves my Princess.biggrin.gif
