NOS 12AU7s with Ayon amps


Just ordered an Ayon Spirit 2 - would like to know what NOS 12AU7s folks may be using with Ayon amps in general if not specific to the Spirit

Thanks

I would try the German TAD 12AU7 tubes. I replaced the Electro Harmonix with the TAD's and it was quite nice. They are not NOS tubes, but it was an improvement.

The Ayon Spirit II is an excelent amp -
It depends. If you like a warmer, sweeter sound; go with something from Britain(Mullard/Brimar). If more detail and transparency is your cup of tea; something from Germany(Telefunken/Siemens). Amperex offerings will get you somewhere between those two. Just don't skimp on your purchase, or you'll rob yourself of much musical enjoyment.
Thanks guys, I also have a Rogue Cronus Magnum , it came with Sylvania & I have Siemens in it now - different presentations but I like it with either. Will experiement per normal.
