Original owner, used on my Ayon Audio Triton for about  month  or about  25 hours.  Included Upscale Audio Box and measurements. Cryo treated.  Will sell the pair for $150 plus shipping and Paypal (was $85 each).   I have an extra pair and wouldn't need this back-upair.  Holy grail tube.

I have 3 of these and can vouch for their performance. Really outstanding,  you can't go wrong here.
