I read in a couple of places that the Woo WA3 is a good match for ZMF headphones (300 Ohms). Since that model is discontinued, what model is a good match? Is the WA6 the replacement?

Yes, sadly the WA3 has been discontinued. The WA6 is probably the closest replacement in the Woo Audio product range, but there are other brands of OTL tube amps that I've read work well with ZMF headphones. I only have experience with the WA3 myself.

The WA2 is the closest replacement. They're both OTLs. I can guarantee that the WA2 sounds superb with the ZMFs. I have both.

Anyone planning on selling their WA6SE? Let me know please. Cheers.

I’ve been enjoying my new amp but why isn’t there a better glow with my tubes because the tubes seems faint. They are stock tubes that came with the amplifier.

I don't know exactly what types tubes a Wa-5LE can accommodate but a Sophia Electric Princess Mesh Plate sure looked nice glowing brightly on my previous Wa-6SE and now my WA-22!

I can 2nd that the WA2 is surperb with Aeolus. I'm running rca 6as7, jj e88 the rectifiers don't know the brand but they are ez81. The Aeolus sound ridiculously good. I am using a Wells Audio Cipher Tube dac, that adds a big 3d sound and cost a lot more then the amp is worth. The Dac is technically built for 2 channel setups so it's not desk friendly.

WA2 is essentially TWO WA3 in one chassis. It's a great all-tube amplifier for the money. Price is low by today's standards for a point to point wiring amplifier.

The revision WA2 is better then pre amp WA2. Mike told me they improved the circuit by removing the pre amp.

Oh no, what did I do?

This one will be a little custom.

• 6SN7s instead of 13EM7s, like the old-school 234's. This gives up a bit of speaker output, but I only do headphones for now and I want to take advantage of my big 6SN7/6F8G collection.
• XLR inputs will be passthrough so I can use an external pre-amp. This will probably be my Benchmark HPA4, which has the guts of the LA4. I didn't know it when I bought it, but apparently it is now considered by many to be the best preamp in the world (!).
• RCAs will continue to use the 234's volume controls, except now Woo is putting in RK50 pots (like they do in the WA33 Elite) instead of their custom stepped attenuators. At first I was skeptical of this idea since I figured channel-matching would be a bear; after more thought I realized I've hated every stepped atten I'd used in the past for various reasons, and Woo strongly thinks this setup is a better experience. So I'll see how it goes.
• My 1st-gen WA5 is still doing spectacular after six years. Its reliability strongly influenced my decision to continue with Woo. I just wanted to take the next, and last, step up. Another WA234 owner repeated privately to me all of the positive things he's said publicly about it, so I have my fingers crossed.

Almost there with the new KR HP’s getting burned in... I can tell these tubes will be exceptional when they prime.. Also demoing a pair of JPS power cables along with a XLR. So far very happy with these cables and anyone with a tad of glare or brightness try them. I’m trying them from TheCableCompany 3 x cables for $100+ shipping and if you decide to buy the price goes towards the cable or cables.

I am quite chuffed I found this thread. I did a quick search: most of the recommendations for the Woo Audio WA2 seem to centre around the T1 and the HD800. Anyone tried them with the newer headphones like the Utopia, D8000, HE1000v2? A few years back, when I needed space for my 2 electrostatic amps, I had mothballed the WA2 and just remembered how it was so fluid and gorgeous. Hence, thinking of plugging them up now that I have a DI box and so am now able to have more amps fed from my desktop DAC or line out from DAPs. Thanks in advance for your kind suggestions.

You know what the best thing about owning a UE/USAF 596 rectifier tube is? Besides the awesome sound? You're now all set to make in-flight repairs to the radar systems on nuclear bombers:

I'm guessing you don't need the Woo adapter for this.

Fired up the WA2 last night and been listening to music via TH900 and now the Focal Utopia. Almost forgotten how good the WA2 sounds.
