I've had the Ernestolo amp for over 3 months now, and I can say it's now my current favorite T-amp. It's a beautiful looking jewel of an amp, and non hifi people compliment me on it's looks. It sounds even better than it looks with the focused, coherent, and punchy sound the TA2024 chip provides. It sounds even better than the typical TA2024 amp though, because the Ernestolo feeds the TA2024 from a tube preamplifier that is built into the same chassis.
The preamp is a low voltage design (probably what is referred to as "starved plate") that barely makes the tube glow. For visual appeal, there is a very pleasant blue led to light the tube. I got my Ernestolo for $300 on amazon.com. That's significantly more than I've paided for my previous T-amps. Still, it's cheap by audiophile standards, and competitive for a (presumably) Chinese manufactured tube amp. The Ernestolo sounds an order of magnitude better than the Qinpu A-3 for example, and it's only $100 more expensive. If you can live with the cramped and cluttered back panel connections, the fussy powering sequence and in the inevitable pop when you turn it on, you'll be pleased with the sound of the Ernestolo.
