I am willing to buy tubes for less if you can make someone sell them to me.

I will hold out as long as I can, but eventually I'm going to want some better tubes. In the meantime, I will have to be happy with the Sophia Princess and whatever stock tubes Jack sends me.

Ok, I bought this NOS RCA 5R4GY. Any idea what year this tube was manufactured and has anyone else tried this tube?

Just be careful. Many pricy tubes out there sound no different from their cheaper counterparts.

Hi!  Just ordered a silver WA6. Really looking forward to it.

Congrats. I am pondering whether to pull the trigger as the black version is on back order. I would be interest to know how you like it when it arrived and it may just motivate me to place my order

Thanks! It literally just arrived.  I'll try it out tonight and let you know.  
 
What kind of headphones are you using? 

 

[Brumas7]

It is always an excitement to setup these stuff and then get a first listen. Enjoy!
 
I am using the Senn HD650. I still have my Beyer DT770 Pro as backup but I hardly use that now. I tested the new Sony MDR Z1R recently and is planning to get that in next couple of months when stock becomes available. It's impedance is about 65 Ohm and I think the WA6 would be a more suitable amp than OTL headphone amps from what I can understand.

There so much information out there that I'm having a hard time getting the specifics of what I'm looking for.  I have a WA6 and a Marantz  HD-DAC1 that I'm using as a source with Kimber RCA's with WBT connectors.  The Headphones are HE X and Audeze EL-8's.  I'm using a Sophia 274B and NOS GE 6FD7's. My problem is that the lower and mid frequencies are spectacular with a lovely sonic signature however the highs are missing a lot of detail.  I know that by doing an A-B between the Marantz AMP/DAC during the same song.  Is there a recommendation for driver tubes that will give me more highs and more high resolution while maintaining the low and mid's?
 
Thanks in advance,
 
Bob

The 13DE7 is not a commonly used tube and it's 13 volts. The voltage makes it difficult to roll non 13 volt tubes without some modifications.

The good news is that they are cheap on that popular auction site.

I am a very impatient person I have had the woo 6 for roughly 2 weeks and have had roughly 80 hrs burn in on it,
And I still feel that it sounds a bit rough around the edges , I have the princess Sophia 274b and the 13de7s running on the woo
Can’t help but feel disappointed after 80 hrs burn in .
Guys am I being impatient, shall I give the amp more time because at the moment even tho it sounds good it feels a little lifeless
To say the least.
I have a couple of tubes coming the rca 6de7s maybe the 13de7 is not to my liking , I do not want to roll the tubes just yet until the woo and tubes
Are fully burned in .
What’s your opinion guys does the woo 6 eventually open up ?
Cheers guys .

Just be aware 6DE7 is 6 volt 13DE7 is 13 volt not a drop in tube replacement the tube will incinerate very quickly

Just pulled my WA6 out of storage. Was running a USAF-596 with Sophia 6SN7 and found that to be the best combo after much trial and error. I just dropped in a new rectifier and am very surprised at how good it sounds with this new tube, even better than the Mighty 596. I am now looking to play with the other tubes again.

I’m also running a Brooklyn DAC+ and using HD650 and ZMF Eikons.

The Sophia 274B leaves much to be desired. Bloated bottom end, overall veiled sound. If the 13DE7 are anything like their lower voltage siblings, I’d swap those out too. The WA6 design leaves a lot of options for tube rollers. Don’t give up.

Any suggestions for tubes on the budget side of things? I dont want to spend a few hundreds for tubes. :-/
