I am using 6H23 NOS 6922 tubes from Upscale Audio on my ARC LS25 MKI. Results are spectacular.
I am interested in this also!!! I just got some Matsushita tubes from Andy at Vintage Tubes and put them into my ARC PH 3 SE....too soon to tell but I suspect I hear a difference...have to listen more tonight. Anyway, I have heard good comments about Amperex and Semeins. I would like to know if anyone has used them in ARC equipment (LS 25 mkl's)..come on 'Goners....help us out? Thanks to you all!!
