I have boxed the JJ's and probably will sell them. My amps simply did harmonize with them. Straight out of the box, the JJ's were closed in and sounded like they were nasal sounding. I gave them a chance and about 75 hours. That was enough. I ordered another set of the EH KT88's and all was rigth again. I now know that the EH KT88's are the ebst choice for my amps and my listening. If you want the JJ's send me a private e-mail. I will never use them in the these amps.
