I am glad to hear that you discover this special gem. I have an opportunity to hear ST225 at a friend's in Philly driving a 3-way with a pair of 15" woofer. With Paul's expertise in design and manufacturing top tier tube gears, I think he manages to harness the 'tube' warmth and magic into a transistor design so that we can rip the benefits from both worlds coming in a SS box. I have been thoroughly enjoying my TRL mono's and have not being even tempted by any amp upgraditis as yet. I look forward to your review.
