Went through briefly the thread. I have Grado RS1. Used to have MAD EAR but considering Little Dot 1+ for the RS1.
It seems the recommended opamps are: op2107 and LT1364cn8
Recommend Tubes: Mullard M8161 and Mullard ef91
Which is best?
I see that the M8161 is part of the EF92 Family of tubes.
I see now that the EF92: M8161 with op2107 is probably the best followed by Mullard CV131
