ekimg,
Just curious, are you using the stock tubes in the 518ia or have you swapped them out; and if the latter what do you feel is missing that is casuing you to want to go with a separate preamp? I have the 518 and with the exception of the stock 845 swapped in NOS 5AR4, 6L6GCs and 5751s and find it pretty engaging as is. Thanks
