Try TAD EL84 STR tubes in your Zen amp
10/08/17 at 22:57:18
 
I've been running the stock tubes for about a year. Switched in some TAD's and it's the best I've ever heard the amp sound. First thing I noticed is there's added weight to everything. Deep bass is improved, voices sound more natural, resonations of acoustic guitars sound more realistic, and drums hit harder. There's no loss to detail or transparency, but there's an overall warmer sound.

Also, another big improvement imho is to switch out the stock 6n1p for 6n2p,. You can get Vokshod ones for cheap.

I have no desire to try other tubes at this point.

Awesome! I don't know if you've noticed, but I love the TAD EL84 tubes, especially the cryo'd TAD EL84-STR which I get here:

This is a great tube. I do prefer the SV83 in my Taboo Mk IV but these TADs are wonderful in the other two amps I use with this tube type.

I should've gotten those. That's basically what I paid for non cryo. Never hurts to have a backup set  :)

Stock tubes are back in. The TADs are fun but there is a certain magic I missed. I don't know how to describe the sound. Sort of like a holographic sound and more coherent. Never doubt Steve.  8-)

I use this one. It's like the switch on the Zen that makes it sound hotter or more laid back, it's like adding a little more to the forward switch. I think it gives you a little extra gain as well. I've tried going back multiple times to the 6n1p but couldn't do it.

I also replaced the two 6n1p input tubes that come with the Schiit Valhalla 2 headphone amp with these tubes and it sounds a hundred times better to me.

Side note. I like this input tube so much I bought 10 of them because I'm afraid of the tube ever being unavailable and losing that sound.

i tried this tube in my Zen amp. Beautifully, buttery smooth, a presentation that is set back a bit compared to the stock tube, a really nice sound. But i also heard a loss of detail and a touch of realism compared to the stock tube.

i can see how a person would prefer that more laid back, smooth presentation. Sometimes i do. Guess it just depends on the mood i'm in!

i'm also using a Raytheon type 80 as a rectifier. Very nice.

The TAD tube (all EL84 tubes) won't take advantage of the Hazen Grid Mod/Christmas Comes Early Mod, which is why there's a difference in sound. . . . I like the sound of these amps with and without the mod activated, and for much of my listening the EL84 is the most comfortable. The best sources benefit from the mod, the lesser sounding ones get a bit of forgiveness without it, that's been my experience.
