You must have gotten two for that - right? Otherwise, that's a premium price for a Tung Sol rectifier - entering Mullard territory.
I paid around $15, or $20/ea for the two I have - if I recall correctly. Though they are not the ST "Coke Bottle" tubes, which may be more expensive. I haven't been able to find any of those yet.
The Tung Sols are better sounding tubes in almost every tube I've had... but... I don't know that you'll consider them 2x+ better than others. They have a very solid, punchy, smooth sound with pretty good extension, clarity and detail. Soundstage may be a little smaller than the Sophia Princess, though, and resolution may be a little less.
But... we're talking very small differences in sound attributes with any of these tubes - even the Sophia Princess. Though, the Sophia Princess seems it may be better in most aspects of the sound, except the bass slam, and solid punch of the Tung Sols.
