Since I have been in the process of acquiring headphones for my home studio, I need to know all the ins and outs about headphone amplifiers with high ohms.
For example, I am interested in 80 ohm headphones. What happens to the 80, 250 or 600 ohm models and the relatively cheap headphone amplifiers (<€ 100)?
In fact, the headphones that I like have a power of 100mW (Custom Studio), when my sound card (Sound Blaster ZxR) only reaches 80mW at the headphone output. I deduce that I will have power problems at a high volume, around 70-80%, although Creative states that they should support headphones with many ohms.
Do these amplifiers do what they promise? Amplify the sound with enough power to perfectly support 80, 250 or 600 ohm headphones while maintaining a high volume level without distortion?
I have seen compact 4-channel models. It really seems that there are not many options, and manufacturers seem to hide the technical specifications of these devices.
Another issue is how the amplifier can influence the audio quality of the original source. I like how my Sound Blaster ZxR counts, and I don’t want an amplifier to transform the sound in any way. That it was exactly the same as the original, but more powerful, obviously, to support the most demanding headphones.
Although he now chose to acquire 80 ohm headphones, perhaps later he acquires one of 250 ohm. It is always better to look to the future.
Can we discuss these things in this thread? Do you have experience on studio headphone amplifiers for PC?
Here is an example: Auna HA-4CH
