For any WA2 owners that are interested, I have a few pairs of rectifiers (GE and RFT)) and a handful of 6DJ8/6922 tubes that are left over from when I had my WA2. I was going to list them in the classifieds unless anyone wants to buy the lot in bulk? Special discounts apply
Did you perhaps listen to verite before your purchase? The verite does seem more '3d' in a sense than other headphones I owned in the past with the universal pads so hopefully that does it for you but it does read to me like you were expecting a different sound from what you are experiencing now.

The verite sounded alright and had better soundstage using the questyle 800r golden i tested with. Was hoping the tube system would sound more 3d. Not forcing it just trying to achieve optimal setup with my tube amp. My rft ez80 will be arriving soon.
anyone had good experience with mullard driver tubes?
I prefer warm and 3d like soundstage with musical high and low.
With my current tube setup it only sounds good with good quality recordings and too honest with badly produced recordings, I have experienced this with Tidal(Hifi/Master) and also offline music from my KANN ALPHA.
Now I have a feeling that the Russian Gold Lion tubes not perfectly matched with Mullard 6080.
Please help me to find me the perfect matching tubes that can give me that WOW experience!
I do use the Mullard (black plate, Philips rebranded) 6080s. I use 12AT7 type tubes with adapters. These tubes are Brimar CV455 KB/FB (Footscray) and Mullard ‘gold pin’ 6201. Both will satisfy your preferences.

• I will go with the last query first. I have had no issues with noise from the tubes. When no music is on and the volume knob is fully turned clockwise, there is a light hum. At my listening levels and half again, no hum. I make sure that all tube pins, all adapter pins, tube sockets are clean (via oxalic acid metal cleaner first with isopropyl alcohol next).
• The Brimar CV455s are a very dimensional, dynamic, full-frequency tube with a vast openness. The Mullard 6201s are slightly less so but are extremely adept, facile in the low bass and mid-bass. When not using either of these two, it is RFT ECC81 ‘foil getter’ time. I have found that a good 12AT7 type tube coaxes much better sound from the WA2 than does a good 6922 / 6DJ8 / 7308 type tube.
• A point to consider about Woo Audio h/p/a that feature tube rectifiers. In my experience (not the longest by any means), change of rectifier tubes has a dramatic effect on the sound. I have been using RFT EZ81 that have ‘foil getters’: very airy, solid imaging, adept purveyors of low-level detail. Highly recommended!

It is indeed a feature of all woo amps (at least wa2, wa22, wa6se i had) that rectifier matters a lot. I also liked rft ez81. Still have fwo pairs in case i will get back to wa2)
• I have tried Amperex PQ 6922, Amperex PQ 7308, Philips BEL ECC88, Siemens E188CC, Siemens E288CC, Sylvania 6922 (green print).
• Woo Audio does not usually recommend tubes that require an adapter. Woo does make a few adapters for specific use.
• If you wish. I will say that the use of 12AT7 type tubes + adapters has incurred no sonic penalty: only benefits. The only ‘negative’ is the extra outlay for the adapters.
• The best adapters for this use are the 12A*7 —> E88CC from Pulse Tube Store (located in India: maker of the adapters offered by Tubemonger). I (and a few other Head-Fiers) have ordered adapters and tubes on numerous occasions from PTS with no issues pertaining to delivery or to product. The longest delivery time (from India to western Pennsylvania) - from order to arrival - has been eleven calendar days.
The rectifier tubes: RFT EZ81 (w/ foil getters);
The power tubes: Mullard / Philips 6080;
The driver tubes: Brimar CV455 (KB/FB - Footscray plant).
Used in rotation are Tung Sol 5998 (power) and RFT ECC81 (driver w/ foil getters).
Sound is: . With no music playing and volume at maximum, very light hum. At 1.5x normal listening level, no hum. This is my best setup for high impedance headphones: Beyers, Senn, ZMF.
