No need. Go ahead with the OTA v2.01 :)

Cant agree more. I went NOS tung sol 5998 power tubes and amperex 6922 orange globe driver tubes. A-B testing with stock tubes have massively upg. I have ZMF verite, aeolus and HD800S (most surprised to enhance the weak points of these cans). Take your time and enjoy the searching process! 😊

v2.01 installed. Battery issue is fixed. Thanks Ibasso for prompt fix. I notice a slight change or potential improvement. The screen becomes slightly over sensitive. e.g I swiped through the mango player in the song list. sometime it would treat as touch/select then it will play the song...

Anyone experienced android 11 not as snappy as before. I tried v2.0 then use tool 660 downgrade back. Wonder v2.01 has improved?

it works. Thank you :)

Thanks man. can you share the 600 tool link again. it's a dead link. cheers.

Hi Guys, I have the same issue with battery drain and laggy interface of firmware v2.0 . I tried to installv1.07.390 but not allow me to do so. Any tips for me? thks.

Power: TS 5998 Drivers: amperex orange globe 6dj8 (lusher, punchier), sylvania 7308(more transparent and dynamic) RT: lorenz ez81 (I have only tried this and it's better than the stock EH6CA4) All have the 3D effects. Note: I use stock Universe pads. Pad effect from ZMF website. Just my 2 cents...

Anyone the power consumption in watts for WA2?

Power tubes (6080, 6AS7, 5598) comparison. FYR. https://www.superbestaudiofriends.org/index.php?threads/bottlehead-crack.120/page-3

Agreed. I use a pair of 6CA4 EZ81 Lorenz NOS made in Austria. costed me $25 sounds better than stock EH 6CA4. Drivers and Power tubes have the most effect on SQ and S preference.

Something on my doorstep today Woohoo!! Merry Christmas guys!!

OTL Tube amp will sound good on ZMFs and high z HPs. If you have some low z e.g planer. You should consider transformer coupled tube amp like WA6 mentioned.

Good question. May be good for genres R&B, Lo-fi, vocal focus, tap you toes easy just enjoy your music.

I guys. I currently own VO. I want to get a 2nd ZMF cans. Do you think Aeolus would be a good company? Or should I go for Eikon (a closed cans) heard the deep bass extension really well.

Thank you again :)

Hello exchez. Thanks for helping someone like me who just got into tube world. btw, I have read there are few variations of TS5998. something like 1. o-getter 2. d-getter 3. top getter 4. bottom getter Which one should go (sounds the best) for for WA2? cheers, Billy

Very nice. I love the raw cable look than sleeving. just my personal preference. Are they the hybrid one for both cans? how does it compare with stock cable and what has improved? P.S I know Hifiman stock cable how.... cxap they are.... :P Cheers!
