The information contained in this thread has helped me considerably...well, sort of.   I began ordering upgrade tubes for my WA2 before the amp arrived from Woo Audio.  I bit the bullet and bought a pair of TS 5998s; although not inexpensive, it was from reading information here that gave me the confidence that they were right for me.  I am also using EI EZ80 rectifier tubes.  I was lucky enough to land a pair of 1975 Voskhod Gray Shields (from a Head-Fier) for drivers.  All of this has improved the overall performance of the amp considerably.  I have the amp paired with a pair of Beyerdynamic T1s and I am pretty much over the moon with musical enjoyment.   Thanks to all for all the great advice.  .  Three months ago I didn’t know what tube rolling was.  Now, in addition to the stock tubes, I have two pair of power tubes, 7 pair of drivers, and two pair of rectifiers.  Darn good thing I have no spouse to complain.

Love that photo... very cool presentation. What/where is the source?
 
EDIT: I mean source component for music, not the photo.

​I am upgrading (one step at a time), but currently it's my desktop computer and an older CD player running into a NAD D1050 and split to run into the WA2 and into an old Denon Receiver, out through Paradigm speakers and a sub woofer, in both the living room and the Kitchen.  I live in a small third floor flat with a downstairs neighbor, so headphones most of the time, but it's good to have tunes when you're cooking.

I find in my system that the TS5998 has a little more musicality with the WE396A driver as opposed to a reference/ more analytical presentation with the driver types you mentioned above.  It all depends on the recording (and my preference at the moment) as to which one sounds best.

I have a D1050 and while I am less a fan of the headphone amp, the DAC section is quite nice. With the WA2 with what looks like T1s, I don't see what you need to upgrade.

​On the headphone side of things, I feel no need to upgrade, but I would like to get back to my vinyl collection and this will require a new turntable.

Got an excellent deal on a low hour pair of 60's (think 64/65) Amperex USN-CEP 7308's from another head-fi'er... had been wanting to try these out to compare to my '75 Reflektor SWGP Silver Shields... don't know which i like better thus far paired with my T1 gen 1 and Gumby. Only been listening for a little bit so far... can tell they are excellent tubes though! Using them with TS 5998 and RFT EZ80.

Are they American or European manufactured?  The ones made in New York for that period are suppose to be some of the best.  Keep us posted....

I think they are an underrated tube.

Quite neutral. A touch of warmth in their nature. For me.....the lower end is a little like the holland tubes but more air and detail on the top end. A good well priced alternative from the holland tubes.

I find my reflektors to be nicely detailed, from memory perhaps extended or a touch more focus on the top end than the amperex 7308 but on the cleaner/linear side of neutral. Just short of being bright. Maybe mot "musical" in nature but more neutral (again) with good "flow" as rb2013 had stated

Thats my take on these creatures

Hey guys,
 
  I have had WA2 for quite some time and I love it. Unfortunately it seems that my power tubes are dying, since I'm getting some ringing which comes and goes and is extremely irritating so I'm looking for a replacement. Could you guys share some tips with me please ?
 
ps: Right now, I've got 2399 Tung Sol/Chathams which from my research should be similar as 5998's. and for driver tubes I'm using Siemens CCa's which are absolutely wonderful.
 
Thanks a lot, Flisker o/
