Please consider getting a Bravo Audio V1/2. Remember to get a multimeter to adjust biases, as the factory settings are super wacky on mine.
But after adjusting biases, this little amp really sings. It pairs very well with with highly regarded Sennheiser 5xx and 6xx. And it also offers a glimpse
of what you can get with tubes:
1) Very high output impedance. Koss PortaPro sounds like everything is sent down from attic.
2) It works with BA IEMs, such as Ety ER3/4, but the bass is even leaner.
3) It works reasonably well with Hifiman Sundara, the output is high current, but the details are simply lacking.
Best of all, it is only $70 new and $50 used. You really don't lose a fortune if you don't like it. And if you are more daring, you can try modding it to
sound like Garage 1217 amps. If you are tired of the super analytical sound of solid state, you can always retreat to the land of valves and transistors.
