This amp has created a new love for my headphones. I got some studio quality phones because I wanted quality, but never really liked their sound because they were never given enough power. I'm sure that any amp would have done a pretty descent job, but I like the bass response I get from my phones now. They are totally balanced and warm. I can play them pretty loud and it doesn't make me cringe. Other reviewers might say that they are non-fatiguing. I am interested in changing the tube to one that warms the sound even more, but I have heard that the electrical components would need to be investigated as well. As said by a reviewer from another site, "The plate of the 12AU7 is DC coupled to the Gate of the MosFet output driver stage. [...] Any variation in tube DC currents or voltages directly affects the MosFet operating point and tube filament voltage. [...] So 'tube rollers' proceed with caution since changing tube types is not straight forward at all. Even dropping in another 12AU7 can have a negative impact on all DC operating points and sound quality." The amp does run warm, as is to be expected from a tube, and from a Class-A transistor output stage. The heatsinks on the voltage regulators and the output MOSFETs become too hot to touch for more than a couple seconds, though they remain within the safe specs for the devices. Other reviewers have said that creating a steady 24V power supply that is regulated, and higher quality than the one supplied will help the sound. I haven't tried this, but I would be interested in it considering it is an inexpensive upgrade to an already good sound.Read full review
