Are you upgrading to a better tube?

not necessarily. downgrade really, but consolidating for now. I bought a Saga+ Preamp to feed my other newly acquired schiit gear – it’s a matching set. Plus for whatever reason, my wife approves the schiit and wasnt a fan of the Woo around the house. (i think shes the only one who doesnt like the looks of the Fireflies)

that is also needed some times. I have also reached a: I-can’t-buy-anything-for-the-next-months-without-getting-divorced period.
So good idea :+1:


Sorry to bump an older thread, but I’m trying to decide between the Lyr 3 and the Woo WA7 Fireflies. I’m going to be using it with 4 primary headsets - HD600, Elegia, Aeon2, and JH11Pro CIEMs.

Would the WA7 have any difficulties with any of these?

I am the wrong to ask, @antdroid is the right one.

I don’t recommend the wa7 for iems and it’s ok with planars but not great. The lyr3 is better for all gear and tube rolling is cheaper.

Wa7 had very limited and expensive tube options and the stock tubes aren’t that great in my opinion.


Thanks for the information, now I’m really happy I decided to order the Lyr 3. :slight_smile:
