The issue isn't with the Preamp, it's with the Winged C 6550. Don't use them! The last of those tubes that came from the factory before the plant burned down were awful tubes. Use a 6550WE. That is what ARC is using now.
winged c 6550c is not good for ref 5se??
I ordered 3 of svetlanan SED winged C 6550c from 'Upscale audio' last week and it was not shipped until today, so i call them to find out what is going on here.
They told me they didnt send it because " This tube is not going to work well with your audio research amp and it will failed almost every time".
Is it right?
