Er... yes?  But I'd rather spend the money on two monos that spit differential output rather than trying to feed four separate amps

I was just kidding, I guess there is a reason this isn't done....

If everything is perfectly matched between your positive and negative driving amp of each channel, the produced signal should be ok. If you're not pulling more current (due to the higher voltage swing) than the amps can handle, you should be ok. In theory if everything is referenced properly to ground and the aforementioned matching is perfect there shouldn't be a problem... otherwise you'll be cranking some DC through the driver.

Right. Maybe I'll order 4 WA5 mono blocks, then. Always wondered why nobody tried this B)

Why isn't the WA5LE good enough for the HE-6?

 

The LE output is about 1 watt at 120 ohms and the WA5 out of the K1000 output is 8 watts at 120 ohms.

The LE does a decent job but depends on the driver tubes with some tubes it kind of run out of juice. The best result I have had are with a pair of Sylvania 6SN7WGT Short Bottle, Brown Base, Chrome Top.

 

But to be honest I use my Threshold T50 (50 watts/ch Class A in 8 ohms) to really make the sing.

Wow, didn't know that. What's the difference? Inside I mean?

Ok, you go do that. I'm gonna go get me some octo-monoblocks and bi-amp an AKG K340 :biggrin:

I think the main difference is the transformers because in a point of time I asked Jack if my WA5-LE could be modified to add the K1000 output only and he said no because he would need to change the transformers too. I was interested in a K1000 (8 watts output) for the HE-6 but not interested in speakers tabs.

 

I would think I can special order a WA5 without speakers tab but it is not economical convenient to modify an existing WA5-LE to provide the 8 watts.

True. WooAudio has to tap the transformer for K1K duty. He'll be throwin' a switch on my monos. He originally proposed giving me K1K Outputs but gutting the speaker options - I said "no." A switch should be a good compromise.

 

First :rolleyes: I need to find the funds for this project. However, once done, I would only need to get a pigtail with L/R 4-pin XLRs.

I'm in the basement. Trying to get myself right. Perhaps, it would be best if I contact customer service for HiFiMan after my first bowl of Jasmine Pearls. I made a purchase last Friday - HE Adapter. And promptly received an invoice notifying me the item would be shipped Monday. From Illinois. I'm in Cali and it's Friday once again.

 

Before running off to lunch, I sent an email inquiry "Where's my box?" The return reply left me silent:

 

"We forgot to ship it. It went out today, sorry..."

 

:blink: No need to contact the buyer for more options? No offer to expedite?? 

:deadhorse:

 

That I even had to chase someone in the first place... but I digress.:rolleyes:

Why did you get an HE-adapter? Your cable has pigtails. Plus there has been experiences of coloration from that adapter.

Does the color rub off?

:biggrin: Coloration? I'm using a Preamp, could there be any more colour coming in? I got the adapter to protect my vacuum tube monaural amps. The pigtails for the Sansui speaker taps.

the adapter i got from Blue Circle is a little cleaner i think that the the HE adapter, plus you can switch around the series resistors.  It costs more though.
