My 2c. I've tried quite a few headphone amps over the years. These are the ones I owned/tested more than once.Just saw Auris Nirvana specs, It uses EL34 tubes which are not direct heated tubes (DHT), no wonder it has very low noise. For DHT tubes like 300B, Class A linear powered, it's almost impossible that you can eliminate noise/hum without sacrificing sound quality. CMIIW.

I've tried two different HA300, both in show conditions, one quite a bit quieter the other exhibit a very noticeable amount of noise regardless of output impedance. Noise dropped significantly when using planar. The EC, DNA and Woo amps are dead silent regardless of gain and these are DHT.
