I have an opportunity to purchase a used WA 33 standard right now however if I did it’ll bother me wondering how much the performance may possibly be if instead I ordered a WA 33 JPS ,.Anyone here compare the two edition’s ?
That was the main reason I didn’t buy a 33, I’m just gonna deal with my WA5 LE, because that’s maxed out.

I have the WA33 standard tubes and using the HE1000se right now. Neither one is really broken in yet, but the music sounds bright and fatiguing - any suggestions?

I’ve just received mine and I got the same first impression: it sounds bright and fatiguing. I’ll be doing some intense burn-in in the next days. Let’s see how it goes.

But all tube amps have to deal with component selection issue.

There will be a WA5 / WA5 LE "Elite Edition", if you will, just by using some better components, such as premium caps, transformers, cables, etc. :dt880smile:

Or you can do the component upgrade by yourself (no matter WA5 LE or WA33) - just need some knowledge and skills, coz it will void the warranty for sure. :)

I think the key differences between WA33 and WA5 are different designs/topologies, so they will sound quite different.

Although I've never heard any other version of the WA33 I purchased my original WA33 (standard) new, then sold it +/-1 1/2yrs later and regretted it so much 1 month later that I purchased another pre-owned WA33 standard without even a thought of buying a different version...that's how good the standard sounds too me...and even better with some nice upgraded tubes.

Thanks for the reply,, Though I hesitated on the purchase he sold it on me ,.I will order the standard model and get some good quality tubes to go along with it.

Can anyone tell me what is the purpose behind these wire connectors from the base to the tube?

It’s how the you have to put in certain tubes. It’s like an adapter

And they look really cool! I have the same tube, and it definitely gets compliments from visitors. Even the ones who have no idea what a tube is.:jecklinsmile:

While the 5U4G rectifier tube coming with WA33 has all connections on the bottom pins, not all tubes work like that...LOL.

The pictured 596 rectifier tube for example has 2 connections moved from the bottom to the top (to avoid possible arcing/interference), so the 2 wires on the adapter are used to connect them back to the bottom (as the bottom socket is wired for 5U4G).

Be careful though the 2 wires are connected to the rectifier plates, so lethal high voltage there - avoid licking them in any case :dt880smile:

Tip for tube amp newbies like myself: the WA33 may sound very shouty and unbalanced at first. Tube burn-in is very real for the WA33. Don't worry: it will sound way better after a few hours of burn in, and continues to improve after a few days of intense listening. I'm getting the 6C45Pi Electro Harmonix Gold-pin and TA-274B this week and the 2A3 KR in the next few weeks. Introducing them incrementally will give me a good sense of how the upgrade tubes improve sound quality.

I just got my zmf Verite closed stabilized headphones. They are plugged into a wa33 and I’m using a holo may as the dac. streaming from roon with hqp and naa.

The wa33 is set to high/low. The volume is barley turned up and it is way too loud. I end up turning the hqp volume to -13.

do you guys have any recommendations? I’m running single ended xlr on the headphones and connecting the mag with wa33 over Xlr.

the susvara sounds awesome on this.

After much experimenting, I ended up setting up my WA33 volume at max volume, and using the Dave to control the volumes. Listening ranging from -15 to -40db depending on music on the Dave. Impedance set at low and gain at low for the Susvara. Tried impedance at high sometimes, but tend to prefer low for now.
