Thanks for the info, I am aware of upscale audio and they do sell quality tubes, I found a pair of older rca 12au7,s and I will try them with the genelex, my goal is to soften the treble a small amount and reduce the gain if this happens and I will be happy.I my have to go to a different tube comination or all of the same brand.The radiotechnique look interesting.
Thanks for the feedback.
