What's wrong with you people? Nobody's heard of Symphonic Line? I was also a tube fanatic, till I've heard their RG line of amps. I've progressed from an RG1 to my current RG7 MK4. In my humble opinion, these gems have the resolution, soul and transparency very few tube amps can match. The ones that do will cost you very dearly. Honestly, they don't sound tubey nor transistory, they just sound like music. Turn them on and never turn them off. Been saving for the Kraft. Just my two cents.
