Interesting. Never heard of this company. Will have to give them a look.

If you follow Josep69's succedding posts, he sold his WA33 and retained his custom Citadel. Read and discover why: Link: https://www.head-fi.org/threads/oblivion-ultrasonic-studios.902926/page-55

Custom Citadel (the silver one) link: http://ultrasonicstudios.org/citadel/

Which unfortunately, I regretted doing about 1 month later very much, so I was aiming to buy another WA33 and was fortunate to find one about another month after that and I no longer own the Custom Citadel.
This is not to say I didn't like the Custom Citadel because it is an excellent sounding amplifier, for sure, but very different from the WA33.

The Linear Tube Audio Z10e looks like a good choice. I’ve been reading about it, and I’m intrigued:

It can play normal and electrostatic headphones too, as a bonus

I think the ampsandsound nautilus would fit your needs. Has balanced in but not out.

Of course there are other non popular brands that have big buck offerings but with little or no impressions/reviews :

Opera - Consonance Linear X

MFE.Technology TA 845 V SE

I sold my original WA33 to joesph69 with a trade of his custom citadel. Week later got another WA33 sold that to fund WA33 Elite Edition. Someone hexed me! It was probably Joe. I’d stay away from companies that produce outside your country because now I’m sending the Citadel to get fixed and it’s going to cost a lot. For me Woo is 2 hours from my house so I could drop it off and go see my buddies in NY. Just sent out a 10lb amp insured for $5000 from PA-California. Had problem with volume control but that was $150 bucks UPS ground. Input the possibility of returning the amp for it to get work done on it to the out the door price. Also can you afford to replace tubes.

I really love the Woo. It sounds so good with every headphone... literally have no desire to change anything.. but I would love an amp that can power dynamics, planars and stats. Would be huge. I am so sick of having to power two different tube amps lol.

I've been watching the thread on this amp, it's just so hard with so few impressions out there.

There is an amp like that.
It's called Paltauf KHV-ESD.
Patltauf has been designing amps for decades and is quite famous in German speaking countries. He is from Austria, which might be a disadvantage for our foreign friends.
He calls this amp the Universal amp, as it will power any headphone known to man.
Musicalhead. de is busy auditioning the amp as we speak.
I am positive he will post his findings soon.
Some info here, you will need to scroll down, as the page starts with ES (electrostatic) version only.

That's an amp I'd love to hear with the Abyss 1266 TC some day. I have the Kenzie Ovation which is much lower power and at lower volumes it does a surprisingly good job with the Abyss.

I've heard and read raving reviews of these beauties:

[sn0gl0be]

Viva egoista 845 is definitely the best headphone amp I’ve owned with the abyss 1266 (but admittedly have never heard the wa33, outside show conditions)

 

[mammal]

I’d stay away from companies that produce outside your country

That has been my issue - unless I get warranty in my local country (like I do with Abyss and dCS) I find it difficult to buy online (most often than not blindly), pay expensive import tax, just to deal with transport/insurance logistics down the line if I ever need warranty.

 

[ThanatosVI]

I can recommend the Octave V16SE.
Certainly in that league and has much cheaper tube Rolling options available.

That said I sporadically think about adding a Wa33 as well

 

[Bonddam]

I did what I should have done from the start and save money Just buy WA5 LE and then add WA234(in my dreams). Found the WA33 not enjoyable for it wasn't musical yeah it's more detailed but that only last so long. I only learned this from talking to Mike over at Woo so I bought the upgraded WA5 LE about 5K and I'm happy I got rid of the the Standard and Elite( Kicking myself for not buying the 234 when I had the money). Last the freakin Wells Audio Dragon level 3 Fing beautiful.
