Thank you for sharing your insights! I will buy an A90D soon and pair it with my Schiit Modi Multibit DAC. I will let you know about how it sounds compared to my excisting pairing together with the silver cable

I'm thinking of pairing my Empys with the new Topping A90D Amp together with the Meze upgrade silver cable (4,4mm). Anyone that is considering the same pairing or got it already? :)

Has anyone yet tried the new Topping A90 Discrete with the Empys? I am tempted to buy one as I got the Silver Upgrade Cable with 4,4mm but running it through a 4,4mm to 6,35mm adapter from amazon and an unbalanced amp. I feel like there is more potential in these waiting to be heard and using...

I got mine from a store as a B-Stock (so basically mint condition) included with the upgrade silver cable for just below 2000 €. I believe it was a good deal. I love my pair!

Thank you Joseph! I found 12SN7's on eBay. https://www.ebay.de/itm/12SN7-GTA-General-Electric-USA-NOS-El-R-hren/222846563481?hash=item33e2b0b499:g:PnwAAOSwMgdX1X8e Do you know what adapters I need? :)

Thank you for your fast reply! Well thats kinda sad! wished I could upgrade my drivers more easily. Wonder if anyone else has WA6-SE with 13DE7's and ugpraded their driver tubes with a positive sonics in sound as a result :confused:

Thanks for the insight :) I'm looking forward to upgrade my stock pair of 13DE7s on my WA6-SE as I upgraded the rectifier tube already. Do you happen to know if your suggested "6SN7" tube would be compatible with my amp?

You can also check out this chart for some comparision between the two. Its from WooAudio - unless you haven't seen it yet. http://wooaudio.com/docs/wooaudio_amplifier_comparisons.pdf

Thank you mowax! Actually I just tried the "twisting" trick on the tube while its on and I could hear how the buzz noise disperses into the background a little bit more depending on how I twisted it. However it always went back to an audible volume right after 6-7 seconds. I feel like I've...

Thank you guys for all the recommendation on rectifier tubes. Looks like my brand new but annoyingly buzzing stock tube is going to be replaced soon. If I look up the Mullard GZ34 I seem to find 10000 diffrent ones, with diffrent shape, price etc. Could you please link me the one I should look...

Thank you Badas. I may consider it but I may also wait for Mike to reply about my case and perhaps till I got a replacement rectifier tube. Despite I don't think I have the right screw driver for the screws being used here. :/

Thanks for the hint! Im going to test that right now. I did however test it already in a completely diffent room where there is no electronic device at all nearby - simply the amp itself and yet it has the some buzz. I got damping material underneath the amp right now (some sort of foam) which...

Thanks Watchdog507 Going to have an eye on the EML 5U4G and United 596 as you have mentioned. Biggest task will be to find someone that ships to Germany

Thank you Spyder1 I checked out Dub's thread but I wasn't sure if they were compatible as they are been tested with 1st gen - I guessed. I will look out for a reasonable priced one now! Thanks

Thank you for your suggestion MIKELAP. Which other rectifier tube for my 2nd gen would you then recommend?

WA6-SE w/ stock tubes + Asus Xonar Essence One (custom opamps) via RCA, Sennheiser HD800 (custom cables)

Thank you Joseph69! I may going to order one now. The external buzz-noise is indeed anoying however the sound is fine. Lets see how another rectifier is going to work out :)

Hey guys! :) I'm a happy new owner of the WA6-SE 2nd gen here in Germany. Since my PSU-amp is making buzz-noise fellow head-fi'ers recommened me to buy a new rectifier tube as mine could be a faulty one. So my question to you guys is: which rectifier tube would you recommened that is...

Thank you everyone for helping me out to find a replacement rectifier tube for my "faulty" stock one. Joseph69, the Brimar 5Z4GY looks like a good deal! I wish I knew if its compatible with the 2nd gen WA6-SE :/

Thank you Mikelap! Yes you are right. So I may going to buy a new rectifier tube while waiting to get a reply from Woo Audio for a possible replacement of the effected tube. What do you guys think about the Sopha Princess 274B? I appreciate the looks of it. Is it compatible with my new WA6-SE...

Thank you for all the help guys! I've contacted Woo Audio regarding the buzz-noise comming from the PSU-amp already. It won't be so easy for me to request a new rectifier tube as I'm living in Germany and getting the amp shipped here was already a "gamble" as its nowhere to be sold in Europe...

Hmm that may be a solution but I just bought it new and I dont have any nother tubes. That and also if you just bought something new and expensive you want it to work properly first before I spend more to tinker with it :)

Got a little problem here: My WA6-SE arrived but... There is an audible external buzz-sound comming from PSU amp (where the big rectifier tube is located at). The unit where the other two smaller tubes are is dead-silent. Whats happening exactly: Turn on the amp The „PSU" amp is flashing...

Previous poster's are right. If in any case you do want to "ugrapde" your cables I would recommend prioritizing for durability, comfort (e.g. headphone cables) and/or looks. I would never recommend buying new cables SOLELY to hope for an elevated sound. For example, I've swapped my HD800's...
